Changelog

Embedded Graphics is a no_std library for adding graphics features to display drivers. It aims to use the minimum amount of memory for builtin graphics objects by leveraging Rust's iterators to avoid large allocations. It targets embedded environments, but can run anywhere like a Raspberry Pi up to full desktop machines.

Changed

(breaking) #274 The Circle is now defined by its bounding box top-left corner and its diameter instead of its center and its radius. To convert your code, you can replace Circle::new(point, radius) by Circle::with_center(point, 2 * radius + 1).
(breaking) #306 The Rectangle is now defined by its top-left corner and its size instead of the top-left and bottom-right corner. To convert your code, you can replace Rectangle::new by Rectangle::with_corners.
(breaking) #312 The methods in the Dimension trait are replaced by a single bounding_box method that returns a Rectangle.
(breaking) #353 Lines with equal start and end points are now drawn by assuming they are oriented horizontally. This means that they are now drawn as a stroke_width high and 1px wide rectangle, instead of not being drawn at all.
(breaking) #353 primitives::line::StyledLineIterator was renamed to primitives::line::StyledIterator.
(breaking) #357 Additional checks for overdraw and out of bounds drawing were added to MockDisplay which can cause tests to panic. See the mock_display module docs for more information.
(breaking) #342 Refactored the DrawTarget trait to better support common hardware capabilities.
(breaking) #360 Make the drawable module private. drawable::Drawable and drawable::Pixel are now exported from the crate root.
(breaking) #390 Triangle.contains now always returns false for colinear triangles.
(breaking) #393 DrawTarget::draw now uses a reference to self instead of taking ownership of self. Because of this change DrawTarget can no longer be implemented for pixel iterators (Iterator<Item = C>), which can now be drawn using the draw method provided by the PixelIteratorExt extension trait.
(breaking) #383 Replaced all IntoIterator impls with a custom IntoPixels trait. To get an iterator over pixels in an item, replace calls to into_iter() with into_pixels().
(breaking) #403 Use an associated type to define the color type for Drawables.
(breaking) #409 DrawTarget::size was removed and DrawTargets are now required also implement Dimensions.
(breaking) #409 The DrawTarget trait was moved from the root of the crate to a new draw_target module. Projects that use the prelude to import DrawTarget won't be affected by this change.
(breaking) #420 To add support for additional image formats now ImageDrawable and OriginDimensions needs to be implemented instead of IntoPixelIterator and ImageDimensions.
(breaking) #420 The color type parameter was removed from the Image struct and is now defined by the associated Color type of an ImageDrawable implementation.

Fixed

#317 The bounding box size for Circles was off by one.
#401 Triangle pixel iterators no longer produce a pixel for each node twice.
#431 Styled primitive bounding boxes now take the stroke width and alignment into account.

Removed

(breaking) #351 Removed the egtext!, text_style! and primitive_style! macros. Use the Text, TextStyleBuilder and PrimitiveStyleBuilder respectively instead.
(breaking) #351 Removed the egcircle!, egrectangle!, egline! and egtriangle! macros.

0.6.2 - 2020-04-20

Fixed

#309 Prevent triangles with off-screen vertices from infinitely looping.

0.6.1 - 2020-04-01

Added

#285 Add multiplication and division by a scalar for Point and Size.

Fixed

#271 Styled Lines are now drawn using the stroke_with specified in the PrimitiveStyle and no longer default to 1px width.

0.6.0 - 2020-03-20

Added

#269 Support for multiline text.
#267 Added a 6x6 hand-drawn variable width font.
#267 Support for variable width fonts.

Fixed

#267 Fonts with CHARACTER_SPACING now properly render the background color between characters.
#276 Fixed Chars like '°' and similar for Font12x16 & Font24x32

0.6.0-beta.2 - 2020-03-06

Fixed

#262 Triangles with a fill color but no stroke color are now rendered instead of not rendered at all.
#262 A triangle with a different stroke and fill color now renders its left-most border with the stroke color, instead of fill color
#262 Triangles and lines with a stroke width of 0 (and no fill for triangles) are no longer drawn.

Added

Added draw_image to DrawTarget trait with default implementation.

0.6.0-beta.1 - 2020-02-17

Added

#257 added the .into_storage() method on PixelColors via the IntoStorage trait to allow for more ergonomic conversion from a color to its raw storage type.

// IntoStorage is included in the prelude.
// You can also import it with use embedded_graphics::pixelcolor::IntoStorage.
+ use embedded_graphics::prelude::*;

- RawU1::from(color).into_inner()
+ color.into_storage()

Added as many #[derive()]s as possible to all embedded-graphics, tinybmp and tinytga types.
Added From<Point> for [i32; 2]
Added From<Size> for [u32; 2]
Added the following fallible conversions to/from Point
- TryFrom<Point> for (u32, u32)
- TryFrom<(u32, u32)> for Point
- TryFrom<Point> for [u32; 2]
- TryFrom<[u32; 2]> for Point
- TryFrom<&[u32; 2]> for Point
#247 Added the ImageData trait. This trait can be implemented in an image format crate to add embedded-graphics support.
#247 Added Image drawable. The Image drawable is used to make an implementation of ImageData, e.g. from tinytga or tinybmp, drawable to a DrawTarget, like a display.

Changed

(breaking) #256 Make PrimitiveStyleBuilder and TextStyleBuilder consuming by following the consuming builder pattern.
(breaking) #247 The raw data Image struct is renamed to ImageRaw. The Image name is reused as a wrapper for other image types that implement the ImageData trait.
(breaking) #247 ImageLE and ImageBE are renamed to ImageRawLE and ImageRawBE respectively.
(breaking) #247 ImageTga and ImageTga are removed, along with their respective enabling features bmp and tga. To use BMP or TGA images, add tinybmp or tinytga to your dependencies with the graphics feature enabled. This allows usage of Bmp and Tga in embedded-graphics contexts. Tinybmp or tinytga usage now looks like this:

Cargo.toml:
```
[dependencies]
embedded-graphics = "0.6.0"
tinybmp = { version = "0.2.0", features = [ "graphics" ]}
```
Your code:
```
use embedded_graphics::{prelude::*, image::Image};
use tinybmp::Bmp;

let image = Bmp::new(include_bytes!("../../../assets/patch.bmp")).unwrap();
let image = Image::new(&image);
display.draw(&image);
```
(breaking) #243 All methods on DrawTarget that handle drawing to/updating the display are now fallible and return Result<(), Self::Error> to allow for error handling in user code. This also affects Drawable::draw(), which now propagates any errors that occur while drawing.
(breaking) #243 DrawTarget::flush() is removed. The display driver itself should provide this method if required.
Expose mock_display::MockDisplay for use in tests, examples, etc in crates that pull embedded-graphics in as a dependency.

0.6.0-alpha.3

Added

#170 Added a 24x32 font based on the existing 12x16 font.

#221 Implemented Drawable for Pixel to draw single pixels.
#215 Added PrimitiveStyleBuilder.
#215 Added TextStyleBuilder.
#224 Added Triangle::from_points which accepts either [Point; 3], or an array of length 3 containing any item that implements Into<Point>.

Fixed

#143, #209 Circles with no stroke are now drawn correctly

Changed

(breaking) The Drawable trait now has a required trait method draw(), which describes how the object will be drawn on the screen. See the docs for more details.
(breaking) The Drawing trait has been renamed to DrawTarget. The required trait method to implement has changed from draw() to draw_pixel(), and optional trait methods have been added to allow an implementing display driver to specify hardware-accelerated methods for drawing graphics primitives.

(breaking) #161 The .fill() and .stroke() style methods are renamed to .fill_color() and .stroke_color() respectively. This is to reduce confusion between names like .stroke() and .stroke_width(). Example:

use embedded_graphics::{
  prelude::*,
  primitives::Circle,
  egcircle
};

let circle = Circle::new(Point::new(20, 20), 5)
    .stroke_width(10)
    .stroke_color(Some(BinaryColor::On))
    .fill_color(Some(BinaryColor::Off));

(breaking) The type of Style::stroke_width changed from u8 to u32.
(breaking) Primitives shapes need to be converted into Styleds to be drawn.
(breaking) The primitive macros like egline don't accept a style setting anymore. Use object.style = new_style instead.
(breaking) The Style struct was replaced by PrimitiveStyle and TextStyle.

(breaking) Text rendering is now implemented using Text, TextStyle and Font objects instead of using Font::render_str.

(breaking) #224 Embedded Graphics macros now use named instead of positional parameters. Styling is now achieved using the style property which receives a PrimitiveStyle for primitives, and a TextStyle. There are convenience macros (primitive_style!() and text_style!() respectively) to make styling objects easier.

use embedded_graphics::{egcircle, egline, egrectangle, egtext, egtriangle, text_style};

// OLD
egcircle!(
    (15, 20),
    10,
    stroke = Some(Rgb565::RED),
    fill = Some(Rgb565::GREEN)
);
// NEW
egcircle!(
    center = (15, 20),
    radius = 10,
    style = primitive_style!(stroke = Rgb565::RED, fill = Rgb565::GREEN)
);

// OLD
egrectangle!(
    (0, 0),
    (64, 64),
    stroke = Some(Rgb565::RED),
    fill = Some(Rgb565::GREEN)
);
// NEW
egrectangle!(
    top_left = (0, 0),
    bottom_right = (64, 64),
    style = primitive_style!(stroke = Rgb565::RED, fill = Rgb565::GREEN)
);

// OLD
egtriangle!((32, 0), (0, 64), (64, 64));
// NEW
egtriangle!(
    points = [(32, 0), (0, 64), (64, 64)],
    style = primitive_style!(stroke = Rgb565::RED, fill = Rgb565::GREEN)
);

// OLD
egline!((32, 0), (0, 64));
// NEW
egline!(
    start = (32, 0),
    end = (0, 64),
    style = primitive_style!(stroke = Rgb565::RED,)
);

// OLD
egtext!("456", (10, 10), font = Font6x8, stroke = Some(Rgb565::RED));
// NEW
egtext!(
    text = "456",
    top_left = (10, 10),
    style = text_style!(font = Font6x8, text_color = Rgb565::RED)
);

Removed

(breaking) The SizedDrawing trait is removed.

0.6.0-alpha.2

Changed

(breaking) Coord and UnsignedCoord are replaced by Point and Size.
(breaking) The Image struct is removed from the prelude. Import it with use embedded_graphics::image::Image instead.
(breaking) Integration with Nalgebra through the nalgebra_support feature is now achieved by converting Nalgebra types into Point or Size instead of Embedded Graphics aliasing Point and Size to nalgebra::Vector2<i32> and nalgebra::Vector2<u32> respectively. Integration now requires calling Point::from(my_nalgebra_var) or my_nalgebra_var.into().

The benefit of this change is to allow more integer primitive types in Vector2. Embedded Graphics should now support u8, u16 and u32 conversions to Size, and u8, u16, i8, i16 and i32 conversions to Point. It also reduces coupling between Nalgebra and Embedded Graphics.
(breaking) Points can no longer be created from (u32, u32), [u32; 2] or &[u32; 2]; these conversions are dangerous as the full range of u32 values cannot be represented by the i32 used for storage inside Point.

(breaking) Pixel now uses the signed Point type as the first element. Display drivers need to implement an additional check if x and y are greater or equal to zero.
(breaking) The image module has been rewritten to support big- and little-endian image formats. Image1BPP, Image8BPP and Image16BPP are no longer available, and have been replaced with the single Image type. To migrate from the previous image types, use Image with a specified pixel color, like this:
```
use embedded_graphics::{
  image::Image,
  pixelcolor::{BinaryColor, Gray8, Rgb565}
};

// Image1BPP
let image: Image<BinaryColor> = Image::new(DATA, 12, 5);

// Image8BPP
let image: Image<Gray8> = Image::new(DATA, 12, 5);

// Image16BPP
let image: Image<Rgb565> = Image::new(DATA, 12, 5);
```
There are other pixel color types available. Take a look at the pixelcolor module for a full list.

If you need to specify an endianness for the image data (like when using multiple bytes per pixel), the ImageLE and ImageBE type aliases have been added.

Removed

(breaking) Coord::clamp_positive is removed.
(breaking) The icoord!() and ucoord!() macros are removed. Use Point::new() or Size::new() respectively instead.

Fixed

The code examples README.md are now checked in CI during crate compilation. They were woefully outdated and have now been fixed.

0.6.0-alpha.1

Major breaking changes ahead! @rfuest has been hard at work making the colours story in Embedded Graphics much richer and easier to use.

As this is an alpha version, please give it a test and report back any issues you find!

Changed

(breaking) Added many colour types

0.5.2

Small doc fixes and other minor changes.

Added

Added low-effort Embedded Graphics logo for https://docs.rs/embedded-graphics

Fixed

Wrap Coord code example in backticks so it's rendered as code by Rustdoc

0.5.1

A couple of breaking changes around naming, mostly polish around public APIs

Added

Changed

(breaking) Primitives macros have been renamed. This is primarily to fix conflicts with std's line!() macro, but I thought I'd take the opportunity to make the names a bit better/more consistent at the same time:
- line -> egline
- triangle -> egtriangle
- rect -> egrectangle
- circle -> egcircle
(breaking) The Rect primitive is now renamed to Rectangle to fit with the other non-truncated primitive names.

0.5.0

A big release, focussed on ergonomics. There are new macros to make drawing and positioning primitives and text much less noisy, as well as changes to the Drawing trait to remove the explicit .into_iter() call when passing objects to it.

Added

Add SizedDrawing trait. This is useful for displays that support partial screen updates. If the passed object has known dimensions (via the Dimensions) trait, a smaller draw area can be specified, reducing the number of bytes sent over the wire. This also opens up the possibility of bufferless display drivers!

Macros for primitives, text, UnsignedCoord and Coord! This should make graphics-heavy code much quicker to write, and much cleaner to read. For example, to create a line and a circle:

Code that looked like this:

display.draw(
    Circle::new(Coord::new(10, 10), 10 as u32)
        .with_stroke(Some(0u8))
        .with_fill(Some(1u8))
        .into_iter(),
);
display.draw(
    Circle::new(Coord::new(10, 10), 10 as u32)
        .translate(Coord::new(10, 10))
        .with_stroke(Some(0u8))
        .with_fill(Some(0u8))
        .into_iter(),
);
display.draw(
    Rect::new(Coord::new(0, 0), Coord::new(64, 64))
        .translate(Coord::new(96 + 32, 32))
        .with_stroke(Some(0u8))
        .with_fill(Some(0u8))
        .into_iter(),
);
display.draw(
    Triangle::new(Coord::new(32, 0), Coord::new(0, 64), Coord::new(64, 64))
        .translate(Coord::new(96 * 2 + 16, 16))
        .with_stroke(Some(0u8))
        .with_fill(Some(1u8))
        .into_iter(),
);

Now looks like this:

display.draw(circle!((10, 10), 10 as u32, stroke = Some(0u8), fill = Some(1u8)));
display.draw(
    circle!((10, 10), 10 as u32, stroke = Some(0u8), fill = Some(0u8))
        .translate(icoord!(10, 10)),

Added pixelcolor::RGB565 to make working with displays and images in the common RGB565 pixel format.

Changed

Drawing#draw now accepts IntoIterator instead of Iter.

This is a breaking change for driver implementors. Client code should still be fine, as .into_iter() can still be called.

This allows passing of embedded_graphics objects without having to explicitly call .into_iter:

// Before (still works)
display.draw(
    Circle::new(Coord::new(10, 10), 10 as u32)
      .into_iter()
);

// After
display.draw(
    Circle::new(Coord::new(10, 10), 10 as u32)
);

This also means that objects can be passed by reference too:

let circle = Circle::new(Coord::new(10, 10), 10 as u32);

display.draw(&circle);

// Reuse `circle` here

(breaking) All with_<prop>() style methods are replaced by their unprefixed <prop>() counterparts - #106
- with_style() -> style()
- with_stroke() -> stroke()
- with_stroke_width() -> stroke_width()
- with_fill() -> fill()
(breaking) ImageBMP and ImageTGA are now disabled by default behind Cargo features
- Get ImageBMP by adding the bmp feature to your Cargo.toml
- Get ImageTGA by adding the tga feature to your Cargo.toml

(breaking) fonts now render with a transparent background by default. To get the old behaviour back, add a fill like this:

// Without macros
Font6x8::render_str("Hello Rust!").fill(Some(1u8.into()));

// With macros
text_6x8!("Hello Rust!", fill = Some(1u8.into()));

Added a bunch of examples and docs. I hope it makes the crate easier to use! Please open an issue if anything is missing or hard to understand.
From is implemented for a few more types for Coord and UnsignedCoord. Among other things, they can now be converted to tuples by calling .into().

Removed

(breaking) PixelColorU* types. Use vanilla u8, u16 or u32 instead.
- PixelColorU8 -> u8
- PixelColorU16 -> u16
- PixelColorU32 -> u32
(breaking) The deprecated .dimensions() method for fonts is replaced by the .size() method from the WithStyle trait. This makes fonts consistent with other embedded-graphics objects

Fixed

Circles with no stroke but Some(...) fill are now rendered instead of skipped.

Embedded graphics objects can now be returned from functions, chained or not. For example:

fn multi() -> impl Iterator<Item = Pixel<u8>> {
    let line = Line::new(Coord::new(0, 1), Coord::new(2, 3))
        .stroke(Some(1u8.into()));

    let circle = Circle::new(Coord::new(5, 5), 3)
        .stroke(Some(1u8.into()));

    line.into_iter().chain(circle)
}
