Animation is no longer played on the PaintBBS NEO continue drawing screen

Previously, when continuing to draw with NEO, the drawing animation of the steps taken was played, and you had to wait for the playback to finish or tap the screen to skip the playback.
With this update, the drawing animation will no longer be played on the continue drawing screen, and only the layer information will be obtained from the animation data and output as a still image on the screen.
This eliminates the need to tap to skip when the animation starts playing.
This behavior is closer to the original PaintBBS.

Review of user authentication code

The user code has been expanded to 64 characters.
The password is no longer used as a seed for the hash value of the authentication code when replacing an image.
To improve the reliability of authentication, the authentication code when replacing an image now includes the article number and article ID as is.
Added identity verification for posted images when replacing an image, and the image is posted only if the user code or IP address matches.

Fixed an issue that occurred when replacing an image/editing an article after deleting an article.

An issue occurs when someone deletes an article while an article is continuing, and the password of a new post posted afterwards is the same.
This is because the "article number" and "password" of the newly posted article are the same.
In this case, The new post is overwritten by the "continuation" post.
The same issue occurs if you delete an article you are editing and then post a new post with the same "article number" and "password" as the article you are editing.
To avoid this issue, the UNIX time of the article is now used to check whether the article you are overwriting when "continuing" or editing is the same as the original article.

The function that checked whether GD was available has been simplified and consolidated into a class method in thumbnail_gd.inc.php.
In PHP8.4, exit() has become a function instead of a language structure, so exit; without parentheses has been changed to exit();.
exit; without parentheses may be deprecated in future versions of PHP.

Bug fix

Fixed a problem where explode() would fail and cause a PHP error if a non-existent article number was intentionally specified during password authentication processing when drawing a continuation.
(This did not occur in normal use, but was recorded as a PHP error in the server error log when an invalid process was performed.)

5MB limit on log file size removed

When the log file exceeded 5MB, the file was cut off in a way that required items were cut off in the middle of the log file.
Therefore, the 5MB limit when acquiring a log file has been removed.
Instead, a check on the log file size has been added.
If the log file exceeds 15MB, an error message will be displayed. (When writing and pressing the paint button)
However, by the time the log file size reaches 15MB, the bulletin board should be quite heavy.
It has been proven that it works up to about 8,000 posts, but if it exceeds that, it is likely to become unstable.

If you want to store more posts, consider using.
satopian/Petit_Note_EN: Petit Note English ver. PHP script for PaintBBS NEO, tegaki.js,AXNOS Paint,ChickenPaint and Klecks. (PHP5.6 - PHP8.4)
https://github.com/satopian/Petit_Note_EN

This is a one thread, one log file format, so you can operate up to 8000 threads instead of 8000 comments.
With 200 posts per thread, you can have 8000x200=1.6 million posts.

Added new configuration item to config.php

The limit value for the log file size check could be set to 15MB uniformly, but now it is configurable.
If you don't have any particular preference, there is no need to add a configuration item.
If the configuration item does not exist, the default limit value of 15MB will be applied.

// Maximum file size limit for the log file (in MB)
// Setting a large value may cause instability.

Replacing Functions Marked for Removal in the PHP 8.4 RFC with New Functions

POTI Board EVO previously used functions that were proposed for removal in the PHP 8.4 RFC. Although these functions were not deprecated due to a slightly higher number of votes against their removal, I have decided to replace them proactively to ensure future compatibility.

New Functions for Cryptographic Operations

Deprecation of uniqid()
I will stop using uniqid() and replace it with random_bytes().

Changing the Hash Algorithm for Duplicate Image Detection from `md5` to `sha256`

Deprecation of md5()
Since the deprecation of md5() was proposed in the PHP 8.4 RFC, the method for generating image hash values to prevent duplicate image posts has been changed from md5 to sha256.

// Reject files with the following image hashes.
$badfile = array("dummyhash","dummyhash2");

If you have specified images to reject, you must reconfigure this setting.

When the total size of PNG format image file and PSD format layer information output by Klecks exceeds the server's allowable size, it displays detailed information on why posting is not possible.
Until now, it only displayed "Your picture upload failed!\nPlease try again!"

ChickenPaint Be has been updated

Displays a more detailed error message when the file size exceeds the server's allowable value.
Displays the current file size and displays the error message "The file size exceeds the server limit."
Previously, it only displayed "Sorry, your drawing could not be saved, please try again later."
If you merge and organize ChickenPaint Be's layers, the file size at the time of posting will be smaller. If you are unable to post because this error message appears, merging the layers may enable posting.

If you have a rental server that has a default limit of 5MB and you want to allow file sizes larger than that, edit php.ini.
POTI-board looks at both post_max_size and upload_max_filesize and uses the smaller of them as the limit value, so you need to adjust the following two upper limits.
Please check the server manual for instructions on how to edit php.ini.

The units in the following setting examples are MB.
Please note that if you set the limit too high, you may be more vulnerable to DDoS attacks.
Considering the stability of JavaScript apps, I think a maximum of 25MB is appropriate.

Example settings

; Maximum size of POST data that PHP will accept.
; Its value may be 0 to disable the limit. It is ignored if POST data reading
; is disabled through enable_post_data_reading.
; https://php.net/post-max-size

Classify the series of GD processes for thumbnail creation to make the source code more readable

As a result of cramming functions into thumbnail_gd.php, the readability of the source code significantly decreased, so we reorganized it into a static class.
thumbnail_gd.php has been deleted.
Use thumbnail_gd.inc.php instead.
thumbnail_gd.php is no longer necessary, but there is no problem if it remains on the server.
Please be careful when deleting, as you may delete a necessary file when trying to delete an unnecessary file.
thumbnail_gd.inc.php` is now a common class with Petit Note.
There is no longer a need to maintain two types of files, one for Petit Note and one for POTI-board.

Fixed a bug that reduced the actual size of drawing images.

// The maximum size for width and height during upload, any larger will be resized.
define("MAX_W_PX", "1024"); //Width
define("MAX_H_PX", "1024"); //Height

Fixed a bug that reduced the image size when the size set with MAX_W_PX or MAX_H_PX was smaller than the maximum size that can be drawn.
The image size limit for drawing images should have been specified as the maximum size that can be drawn, and it was unintended that the image would become smaller than the initial image after posting.

When posting, the screen now scrolls to the posted reply

Because there is an input field at the top, previously the top of the reply screen was displayed once posting was completed.
However, this could make it difficult to tell if the reply comment was posted, so we've made it so that the screen scrolls to a position where the reply comment is visible.

I have improved the function to convert PNG images to JPEG when they exceed MAX_KB, and moved the GD processing that was processed in potiboard.php to thumbnail_gd.php.
By utilizing the existing GD processing, the code in potiboard.php has been shortened.
When drawing, even if the image file size exceeds the value specified in MAX_KB, the post will be completed without an error.
As before, images attached from the posting form will result in an error when they exceed MAX_KB.
This specification has existed until now, but even if the original file size is very large, it will be reduced due to the vertical and horizontal limitations, and if the file size is larger than MAX_KB, PNG will be converted to JPEG, and if the final file size is within the MAX_KB range, the post will be successful.

By using it in combination with a pen or pencil, you can draw more pencil-like lines.
It is also effective when applying thick paint with a watercolor brush.

Disable texture when using eraser

Added a process to disable texture when using eraser.
You can now erase with the eraser even if a texture is selected.

Images can now be restored even if the PC is turned off

PaintBBS NEO has a function to restore images when you move to another page or accidentally close the browser tab, but if the PC is turned off due to a power outage caused by lightning, images cannot be restored.
Backup data was only saved when you moved to another page or closed the tab, so if an unexpected power outage caused by lightning occurred, the data for restoration was not saved.
To address this issue, data for restoration will be saved every 10 strokes.
Data will also be saved if the browser is closed.
The data storage destination has been changed to local storage, similar to mobile devices.
However, this alone will still leave problems.
Test drawing data, etc. will continue to be saved for more than a week and may be restored at unexpected times.
Taking this into consideration, restoration data older than three days will be automatically discarded.
Due to recent climate change, power outages due to thunderstorms are increasing.
With PaintBBS NEO v1.6.5, you can now restore your Drawing bulletin board data even in the event of a sudden power outage.

Operation has been confirmed on PC versions of Chrome, Edge, and Firefox.

ChickenPaint Be's Update

The brand logo is now intentionally visible even in smartphone mode to prevent accidentally tapping the browser home button.
The shortcut menu to hide palettes now spans the entire width of the device.
Previously, the spacing was too narrow, so it was sometimes impossible to tap the yellow shortcut menu where you intended.

2024/06/06 v6.31.20

In v1.36.10, we fixed the issue of the canvas size not returning to full screen after entering numerical values for blurring, grid settings, etc., when using the ChickenPaint menu on a smartphone. However, there was an issue with the palette placement being misaligned when performing this operation, which remained as an issue.
We found that this issue was caused by both the modal window and the Hamburger menu being displayed, so we set it so that the display event of the modal window is obtained and the Hamburger menu is automatically closed.
This fixed the issue of the palette placement being misaligned.
Detects changes in the orientation of the smartphone or tablet and initializes the palette placement of ChickenPaint.
In v6.31.10, we added a process to initialize the palette placement when the window size was changed, but the appearance of the on-screen keyboard when renaming a layer was detected as a window size change, making it impossible to change the layer name, so we decided to initialize the palette placement when the smartphone or tablet orientation was changed.
If you want to change brushes while drawing, collapsing the palette each time would require more taps.
Since you can hide all palettes by tapping the shortcut menu in Mobile mode, we have removed the auto-collapse feature for tool palettes.
Smartphone mode with collapsed palettes can now be displayed even on smartphones with large screens.

2024/06/01 v6.31.10

Fixed an issue where the canvas size would not return to full screen after entering numerical values for blurring, grid settings, etc., when using the ChickenPaint menu on a smartphone.
To address the issue where the layer palette would not appear in the expected position when tilting the smartphone vertically or horizontally, the palette layout is now automatically initialized when the screen is resized.
The palette layout is also initialized every time the browser window size is changed on a PC.
This also solves the issue where the palette would shift to the left when the window width was narrowed and would not return to its original position even if the window was widened again.
However, since the palette layout is initialized even if the window is changed slightly, problems may occur if you want to move the palette position while drawing.
However, it will not be initialized unless the window size is changed, so there should be no problem if you draw with a fixed browsers window size.

twitter.com→x.com

Even if the setting is twitter.com or x.com, a SNS sharing link will now be created with the x.com URL.

// Servers displayed in the list when sharing on SNS
//Example ["Display name","https://example.com (SNS server URL)"], (comma is required at the end)
$servers =
[

	["X","https://x.com"],
	["Bluesky","https://bsky.app"],
	["pawoo.net","https://pawoo.net"],
	["fedibird.com","https://fedibird.com"],
	["misskey.io","https://misskey.io"],
	["misskey.design","https://misskey.design"],
	["nijimiss.moe","https://nijimiss.moe"],
	["sushi.ski","https://sushi.ski"],

];

You can now create a link to x.com without any problems even if the URL of X (old Twitter) in config.php remains twitter.com.
If you don't mind leaving the name of the SNS that opens in the list as "Twitter", there is no need to modify config.php.
However, the settings in config.php take precedence, so if you want to display the old Twitter as "X", change to ["X","https://x.com"] ,.

Improvement

Even if Bluesky is not in the sharing list, you can now share to Bluesky by directly entering https://bsky.app.
Fixed an issue where when sharing to X, Bluesky, Misskey, etc. on a smartphone, the app version would launch and the shared server selection screen would remain on the Chrome side.
We solved this problem by closing the screen when the focus is removed from the SNS shared server list screen.
However, if the screen has already been moved from the list screen to an SNS site, it will not close even if the focus is removed.
If so, it's because you're already typing or viewing a social media post.
Also resolved the problem that occurred when using the app on a PC, where multiple SNS sharing windows remained open.

Fixed an issue where the ChickenPaintn screen would remain scrolled and the menu bar would disappear when you finished using the iPad's onscreen keyboard.

Fixed an issue where IP address check did not work when using Java Applet + IPv6

The IP address sent by the Java applet is IPv4, but the PHP script receives an IPv6 IP address.
As a result, there were cases where posts were not determined to be by the same person.
Fixed an issue where the image would not be displayed in the posted image list even if you posted a drawing image due to an IP address mismatch.
Even if the IP addresses do not match, if the cookies match, the image will be displayed in the posted image list, so this problem rarely occurred.

"Tegaki" updated

In addition to the conventional right-click, you can now register colors in the palette by long-pressing with a pen or finger.
However, if you press the palette for a long time, it will become a long press and will register the color instead of selecting the color.
Please be careful not to press for too long when just picking up colors.

"ChickenPaint Be" updated

Added shortcut keys. You can now invert negative and positive images using "ctrl+i".
It is also possible to invert negative and positive layer masks. You can also invert the visible area by inverting the negative/positive mask.

Improved key input restrictions for PaintBBS NEO

On the screen where NEO is running, key operations other than NEO's keyboard shortcut keys and text input could not be performed.
Therefore, it was only possible to use the right-click menu of the mouse to paste palette data to the "textarea" of the dynamic palette.
It was also not possible to edit the pasted palette data.

By acquiring and pasting dynamic palette data, you can use your own palette on any bulletin board.
With this update, it is now possible to enter keys in the palette data input field.
Like the original PaintBBS, ctrl+v (paste) crtl+x (cut) ctrl+c (copy) crtl+a (select all), etc. can now be used in the palette data input field.

Additionally, an issue where browser shortcut keys such as ctrl+r (reload) would work when using the text input function has been fixed.

CheerpJ v3.0 supports Shi-Painter's drawing playback function and detailed settings of dynamic palette

CheerpJ v3.0 is now available

CheerpJ is a tool that converts Java applets to JavaScript on your browser.
Previously, with CheerpJ v2, it was not possible to adjust the brightness or create gradients in the dynamic palette of the Java applet ShiPainter or PaintBBS. 　

Unfortunately, CheerpJ v3 is designed to not work on XAMPP's Localhost, and posts by Shi-Painter will also fail.
This can be said to be a specification of CheerpJ because it only supports Java applets that are published on the Internet, not in the local environment.

If you need CheerpJ v2.3, set it in config.php

//Use an older version of CheerpJ Yes:1 No:0
//If there is a problem with the latest version, do this:1

Use "Lightbox" for pop-up displays

"Luminous" which was used to display popup images, The LICENSE file has been removed from the repository, so LICENSE is now unknown.
To resolve this issue, use a "Lightbox" to display the popup.
I'm customizing the "Lightbox" to create a "luminous" like popup.

Make transparent PNG transparent
Since the background color of the "Lightbox" is white, I made the background part transparent so that the background of the transparent PNG image can be seen through.
Long press on image to save
In "Lightbox", you cannot save an image by long-pressing it, so I adjusted the CSS so that you can save it by long-pressing the image.
Reposition the forward and backward navigation bars.
The arrows that display the previous and next images that were displayed above the image have been repositioned to match the left and right width, and if there is space on the left and right, the navigation arrows will be displayed on the left and right.
Close button
Images now close when pressed anywhere other than the fo prev / next navigation arrows.
As a result, the close button is no longer needed.

Change the loading circle GIF to two large and small circles created with transparent PNG. Rotate the image using CSS3.

Fixed an issue where it would become impossible to post if cookies disappeared while drawing

The system that matches the cookie value set in HTML with the actual cookie value has been abolished.
Even if the cookie does not exist at the time of posting, it is now possible to reissue the user code cookie and post.
I believe that this not only addresses the issue of cookies disappearing from the user's browser, but also the issue of cookies not being able to be verified due to the server's WAF settings.
Also, information was packed in the extension header of Shi-Painter and PaintBBS NEO, but we have switched to a method of obtaining it with GET parameters instead of via the extension header.
To maintain compatibility, if it is not possible to obtain with GET, it is now possible to obtain with extension header.

This eliminates the need to process the image a second time if the width and height exceed the specified values.

Previously, both the drawn image and the uploaded image were converted from PNG to JPEG when the IMAGE_SIZE setting was exceeded, but now only the uploaded image is affected by the setting.

If an error occurs and you cannot post because the posting capacity limit of MAX_KB is exceeded, both the drawn image and the uploaded image will be converted from PNG to JPEG.
After conversion, if the file size is reduced to a size that can be posted, it will be posted in JPEG format.

You can now set the width and height of the window that opens when sharing on SNS in config.php.

Added a new setting item to config.php.

// Width and height of window to open when SNS sharing

//window width initial value 350
define("SNS_WINDOW_WIDTH","350"); 
//window height initial value 490 
define("SNS_WINDOW_HEIGHT","490");

When adding a server for SNS sharing, the height of the shared screen window was insufficient and scrolling was sometimes required.
Solved the problem by making it possible to set the width and height of the shared screen of the server list when sharing with SNS.
If the above setting items do not exist in config.php, the default values of 350px width and 490px height will be applied.

Search results that were previously displayed with a URL like "search.php?". The URL will be changed like "potiboard.php?mode=search&".

Externalize and standardize CSS switching part of templates MONO

In order to deal with the problem that the aspect ratio of the drawing area is broken when the orientation of the device is changed on the iPad, we have included a version of ChickenPaint that has been customized and built independently. (Temporary measure until the problem is resolved)
This issue only occurs when using ChickenPaint in fullscreen mode.
Therefore, I stopped starting in full screen mode and started in normal mode.
You can switch the display to full screen mode by selecting full screen mode from ChickenPaint's menu bar.

Improvements

Fix WCS dynamic palette script's deprecated JavaScript Rewrote substr() to substring() .
String.prototype.substr() - JavaScript | MDN MDN
Added a "Post in the same thread" checkbox.

Added a "Post in the same thread" checkbox.
However, in the case of "image replacement", there is no choice but to post in the same thread, so this option is unnecessary.

Therefore, I used JavaScript to display the "Post in the same thread" checkbox only when a new post is selected.

bad host chek

When a user has the same host name and IP address, we made it possible to specify a few characters from the front of the IP address displayed as the host name and reject it with a prefix match.

$badhost =["example.com","100.100.200"];

If set like this:

"example.com" will be rejected with a suffix match, and "100.100.200" will be rejected with a prefix match.

define("USE_URL_INPUT_FIELD", "1");
//No: 0, the URL field disappears from the form input fields.
// Even if the form is faked, the URL will not be entered.

In addition to prohibiting the writing of URLs in the text, if you can also make it impossible to write URLs in the URL field, you can eliminate advertisement spam whose purpose is to write URLs.
URL judgment of URL writing prohibition in the text is quite strict, so even if http:// is omitted, it should be almost impossible to write URL of advertisement spam.

Fixed an issue where the template could not be sent due to a JavaScript error when the URL or subject fields did not exist.

It's not a bug, but I've rewritten the JavaScript so that it works fine even if the template is modified by the user.

In PaintBBS NEO, improved so that the screen does not move up and down when manipulating the canvas area such as copy and layer combination.

If the width of the terminal is large compared to the canvas size, it will not scroll even if you grab the mesh of NEO.
This is because the screen moves up and down when copying, layer merging, and Bz curve operations.
However, you can now grab and scroll the mesh when zooming in with pinch zoom.
This is to avoid inoperability.
These are implemented with inline JavaScript in NEO's paint screen, so you'll need to update the paint screen template.

Changed communication of PaintBBS NEO from raw data to formData to avoid false positive error by WAF.

In order to be able to post to the conventional oekaki bulletin board, we modified NEO, which used to send raw data, and made it possible to send header, image, and timelapse animetion data with formData.
With this change, the probability that the conventional WAF will detect NEO transmission data as an attack and block it will be greatly reduced, and the probability of successful posting will be dramatically increased.
Added an option to send data individually with formData so that WAF does not judge it as an attack. by satopian Pull Request #94 funige/neo

Important changes

Receipt of shi-Painter data is done by picpost.php as before.
However, the data of PaintBBS NEO is received by newly added saveneo.php.
If you forget to upload this file, you will not be able to post from NEO, so be sure to update it.
Transfer it to the same directory as potiboard.php.

A parameter has been added to switch to the formData submit mode.

Changed the config.php

Until now, it was not possible to remove PaintBBS NEO from apps that use it, but now you can choose to use or not use NEO.
If you set it to not use all, it will be a setting that does not use the drawing function.
You can also set it to use only Klecks or only ChickenPaint.
When there is only one app to use, the pull-down menu for app selection disappears and the screen becomes clean.

Limited by drawing time

For example, if you want to reject submissions with only lines drawn in less than 1 minute,

// Security timer (unit: seconds). If not set, use ""
define("SECURITY_TIMER", "");

It was possible to specify the minimum required drawing time with , but until now, it was effective only for Shi-Painter and PaintBBS NEO.
With this update, ChickenPaint and Klecks now have this setting enabled.
In the old method, when there was a violation, it was possible to jump to another site (for example, the Metropolitan Police Department site), but instead of that method, an alert will open "Please draw for another 30 seconds.".

It has become easier and more convenient to upload and paint PaintBBS NEO and Java Shi Painter videos from the administrator screen.
Until now, it was necessary to specify the canvas size before loading the pch animation file into the canvas.
With v5.52, you can now automatically get the canvas size from the animation file.
However, it is necessary to specify the canvas size when uploading the animation file of the Java version of PaintBBS.
For HTML5 version PaintBBS NEO, you can automatically get the canvas size when uploading animation files.

PaintBBS NEO update v1.5.16
Solved the problem that cookies could not be read with JavaScript when WAF (Web Application Firewall) was turned on.
If WAF is turned on, cookies are encrypted and have the httpOnly attribute.
POTI-board uses JavaScript to load cookies into static HTML files.
Therefore, with the conventional POTI-board, it was not possible to read the cookie of the form input content when the WAF was turned on.
I solved this problem by issuing a form input cookie not only in PHP programs, but also in JavaScript.
However, it is safer to use httpOnly cookies, which prevent JavaScript from reading the cookie.
There is also a drawing board that uses httpOnly cookies.

Log conversion from POTI-board is also possible.

Adding JavaScript to HTML files to emit cookies for form inputs increases the number of lines of inline JavaScript.
So I externalized my JavaScript.
This externalized JavaScript also includes the back to top button JavaScript and the Luminous image popup JavaScript.
We apologize for the inconvenience and the need to update templates frequently.
A directory for JavaScript has also been added, such as templates/mono_en/js/.
Please note that if you forget to upload this directory, things like the back button that appears when you scroll down or the JavaScript that appears on the same screen when you click on an image will not work.

Just upload all new installations.

Improvements

Changed the format of the canvas size pull-down menu formula generation loop to prevent XSS.
Removed self-closing tag due to warnings when checked by W3C Markup Validation Service.
Add same-origin check. Illegal posts from different origins are now rejected.
However, for browsers that do not support Orijin headers, such as Edge's IE mode, Orijin headers are not checked.
This is because if this check becomes mandatory, it will not be possible to start the shi-painter using Java.
CheerpJ, for example, cannot smoothly play Shi-Painter's drawing animation, so Java must be started.
Protection against directory traversal attacks. Invalidate hierarchies such as ../../ in basename() when variables are entered in fopen().
Rejection when the password is incorrect 5 times in a row.
If you enter the wrong administrator password five times in a row, you can now refuse to enter it any more.
If you want to use this function, please add the following setting items anywhere in config.php.

/safety/

//Reject if admin password is wrong for her 5 times in a row
// (1: Enabled, 0: Disabled)
// 1: Enabled for more security, but if the login page is locked it will take more effort to unlock it.

define("CHECK_PASSWORD_INPUT_ERROR_COUNT", "0");

// Access via ftp etc.
// Remove the templates/errorlog/error.log and you should be able to login again.
//This file contains the IP addresses of clients who entered an incorrect admin password.

Changed the method to get IP address and host name because some servers cannot get IP address with getenv().
Use uniqid() to emit user-code repcode. It now changes in micro time units.
Increased the replacement code length from 8 to 12 characters.
Added original error message for WAF false positive to PaintBBS NEO.

[2022/11/30] v5.36.8

update

Updated Klecks.
Fixed brush shortcut key behavior.
Updated BladeOne to v4.7.1.

improvement

Even if the timestamps used in the working files overlap, advance the post time by 1 second so that the timestamps do not overlap.
Previously, the working file could be overwritten by another file.
An error does not occur when the post time to be compared is in the future.
In the post waiting time calculation process, even if the post time after the current time is detected, it will not be an error.
For example, if the posting time is delayed by one year due to some mistake, the next posting will not be possible until one year has passed. To avoid this, if the waiting time is a negative value, it will pass without generating an error.
BladeOne v4.7.1. Along with that, I changed potiboard.php to automatically generate the cache directory.
The cache directory auto-generation feature has been removed from BladeOne. As an alternative function, added a cache directory auto-creation function to potiboard.php.
Change the permission of files that need to be written in advance to 0606 (606). The log file that cannot be viewed externally is 0600 (600).
The types of error messages have increased when posting OEKAKI images fails.

Improvements

Template Common

When you click the image file link on the management screen, it now pops up with luminous.
Previously, images were opened in separate tabs.
Corrected [tweet] to [Tweet].
Corrected [TOOL] to [Tool].

Template MONO

Added back to top page function that is displayed when scrolling to template MONO.
Display optimized for smartphones. If the resolution is iPad (768px) , unfloat the image. Set the image margins to 0.
As a result, the left and right margins of the image displayed on the smartphone are the same.
Previously, the margin on the right side of the screen was larger.
・The administrator can now edit the article by clicking the article number on the MONO administrator deletion screen.

Security

If the script content of CheerpJ Applet Runner has been tampered with by hacking, etc., it will be detected and the script will not be executed.
Subresource Integrity See MDN.
If you change the version of CheerpJ, it will not work unless you change the hash value.
However, the calculated hash value is included in the latest version of potiboard.php
・If the image file received by picpost.php, which receives data from the Shi applet or PaintBBS NEO, is not jpeg, png, etc. image, it will be judged as illegal and deleted.

When using Shii applet and PaintBBS NEO, the behavior of rejection due to the time required for drawing or the number of steps required has been changed.

・shi-chan has developed a function to redirect the drawing screen to the police site when the drawing time is short or the number of drawing processes is small.
However, this feature was impractical and of no use.
Therefore, instead of suddenly jumping to the specified URL from the drawing screen, we changed the specification to display an alert on the drawing screen that "drawing time is too short" and "the number of steps is low".

Compulsory thumbnail function is back

Restored the force thumbnail feature that was in v1.3.
Using the latest thumbnail_gd.php turns this feature on.
If the file size exceeds 1MB, a thumbnail image in jpeg format will be output.
Assumed case. If a GIF animation image file that is small in height and width but large in file size exceeds 1 MB, a thumbnail image in JPEG format will be displayed instead of the GIF animation.
Click the image to view the original GIF animation.

others

Changed the initial error message to switch automatically between Japanese and English.
Reduce load by avoiding unnecessary processing. For example, if there are no comments, you don't have to check the length of the comment or the bad words, so returning immediately reduces the load.

update Klecks

Fixes an issue where white fills after using distortion tool show lines that follow the shape of the Liquify.
Added how-to video link to help page and added gradient shortcut keys section.

Updated BladeOne to v4.6.

Bug fixes

Fixed a bug that an E-WARNING level PHP error occurred when specifying an article number other than the article number of the thread's parent on the reply screen.
Please update potiboard.php.

Improvements

If the password field is blank for password authentication when drawing a continuation or download authentication of pch, chi, psd, the cookie password will be used instead.
Unified to the same behavior as password authentication during edit function.
Fixed function check_password() for password checking. Password authentication will not succeed if no password is entered and the password is not present in the cookie.
Fixed the multilingual support of the mail notification function was insufficient.
Increased page number spacing for template MONO.
Fixed paint screen's clock javascript .
Changed the unit of file size on the managed post screen from bytes to kb.

[2022/08/16] v5.23.8

Update

Updated Klecks to the latest version.
Added noise filter.

Updated BladeOne to v4.5.5.
Updated jQuery to v3.6.0.
Since the existence of the file is checked, the program will not run if the included jQuery does not exist.
The case an error message telling you that the file does not exist.

Improvements

Fixed clickjacking vulnerability.
It will not be possible to display in frames or iframes.
It's more secure, but I know some people want to display it in a frame.
Therefore, we added a new setting item to config.php so that you can select whether or not to display it in the frame.
If you do not need to display in the frame, you do not need to add setting items.

// Deny display in iframe:  (1: Deny, 0: Allow)
// We strongly recommend "Deny" to avoid security risks.
define('X_FRAME_OPTIONS_DENY', '1');

I think it is difficult to rewrite config.php from scratch, so if you add the above setting items anywhere, you will be able to display it in the frame.

Improved mobile usability.
Optimized tap target size and spacing.
Improved page loading speed
Prefetch externally loaded JavaScript such as jQuery and loadcookie.js to avoid rendering blocking.
JavaScript execution timing to DOMContentLoaded.
Fixed a fatal error if not written carefully. error() function to built-in function die().
Enabled to change the jQuery version without touching the template directly.
Added width and height of image in search screen.
In order to speed up loading speed, loading="lazy" is not applied to the range displayed from the beginning.
The JavaScript description of the timer under the PaintBBS startup screen was deprecated, so it has been fixed.
After setting the content security policy, the clock on the drawing screen of POTI-board stopped working. ｜Satopian｜note

[2022/07/11] v5.20.2

Improvement

Reduced the probability of duplicate file names when posting drawing images to 1/1000.
Even if it is duplicated, 1 second will be added to the posting time.

Improvement

Klecks Japanese translation

Translated Klecks into Japanese.
I was able to bundle a Japanese version with POTI-board.
This new version of Klecks will automatically detect your browser's language priority and switch languages for you.
You can also specify the language to use regardless of the browser language setting.
You can select English, German, or Japanese.
Chinese is only in Simplified Chinese and details are still in English.
Japanese translation resources have already been merged into the klecks repository.

The download button for the application-specific file has been created.

App-specific format list

. Pch file (PaintBBS)
. Chi file (ChickenPaint)
. Psd file (Klecks)

The file containing the layer information for Klecks is a .psd file in Photoshop format.
The downloaded .psd file can be opened by CSP, SAI and many other apps.
.pch and .chi can be opened with NEO and ChickenPaint, respectively.
If you attach .pch, .chi, .psd from the administrator posting screen and press the paint button, you can load it on the canvas and post it.

Transparent PNG, change the transparent part of the thumbnail of transparent GIF to white

Fixed the problem that the transparent part of transparent PNG was black when it was converted to JPEG.
It is not a mistake that the transparent color is black, but since it often results in unintended results, when converting from transparent GIF or transparent PNG to JPEG, the transparent color is converted to white.

Bug fixes

Fixed the case where a minor error occurred when operating the upload format specific to the paint application used when logging in to the administrator, and the automatic deletion function of unnecessary temporary files such as pch, chi, and psd.
