DWIN ICO Tool

Tool to process DWIN LCD display .ICO files. This is the C# .NET version of the original by Brent Burton [@b-pub].

What

DWIN LCD displays use a number of image and container files to skin the UI elements on the display. These displays are used on Creality's Ender 3 v2 and other 3d printers, and the configuration files to support these displays is included in the Marlin firmware.

One file they use is "9.ICO", which is a structured file containing the icons.

How-To

Extracting the images

There are two ways at the moment:

• Drag and drop the "9.ICO" to the executable file
• Or pass the file ("9.ICO") as an argument in the command line

A "out" folder will be created with all the images in the form of INDEX_NAME.jpg See the dwin.h file from Marlin for their indices and names.

Making a .ICO

Same as extracting the images:

• Drag and drop the "out" folder to the executable file
• Or pass the folder ("out") as an argument in the command line

An "out.ICO" file will be created.

Examples

Using powershell:

1. Assuming 9.ico is the file: .\DwinIcoTool.exe 9.ico

2. Assuming "out" is the folder containing all the images: .\DwinIcoTool.exe out

Dependencies

• .NET Framework 4

This should work on Windows 10 out of the box (Tested on Windows Sandbox).

Test

I tested this with the 9.ICO file from Marlin configuration examples for the Creality Ender 3 V2. Extracting the images and redoing the .ico file without modifying produces the same file as the original.

I DID NOT TEST FLASHING A MODIFIED ONE.
