Test generic C implementations on a little-endian target on CI

8

Part of #1455 `ring` ships optimized assembly implementations for x86 and ARM. The generic C/Rust fallback implementations used on other architectures also need to be tested, and the test coverage...

Add support for ARM hardware intrinsics

16

ARM provides intrinsics to convert from f32 to f16 since ARMv8, see e.g. [VCVT-F16-F32](https://developer.arm.com/documentation/den0018/a/NEON-Intrinsics-Reference/Floating-point/VCVT-F16-F32) Unfortunately the Rust standard library [does not implement this intrinsic yet,](https://doc.rust-lang.org/stable/std/?search=VCVT_F16_F32) even though it does implement...

Following the steps in https://github.com/GoogleCloudPlatform/nodejs-docs-samples/blob/main/CONTRIBUTING.md#run-the-tests-for-a-single-sample results in the following error: ``` $ cd datastore/ $ npm test > test > echo 'Please run tests in each sample directory.' && exit...

Perspective guide cursor

10

Sketchbook Pro added a perspective guide mode in addition to straight lines, ellipses, etc. Here's a demo: https://www.youtube.com/watch?v=r96G15n08Y4 It would be nice to have something similar in MyPaint.

Document the interaction betweeen `Frames::collect_frames()` and memory limits

1

[`image::Frames::collect_frames()`](https://docs.rs/image/latest/image/struct.Frames.html#method.collect_frames) currently does not honor memory limits. I am modifying the underlying decoders to honor memory limits. GIF has landed in #2090, and I am working on PNG now. The...

PNG decoding relies on `output_buffer_size()` function that may overflow

1

This happens in image 0.24.8 ## Expected Images with buffer sizes too large for `usize` rejected early ## Actual behaviour I see PNG decoding code using `output_buffer_size()` from the PNG...

CI fuzz job takes a long time not because it fuzzes for a while, but because it takes a long time to compile. It should be made to use caching,...

This happens in `image` v0.24.7 as well as the latest git on commit 96b8cee8fef5893e49dc1c79a654b962fcbe2be8 The following function is currently called for every pixel in the image when decoding animated GIFs:...

RAII for `Limits.max_alloc`

4

Right now the [`Limits`](https://docs.rs/image/latest/image/io/struct.Limits.html) struct provides methods to reserve and free memory from within its memory budget by calling `.reserve()` and `.free()`. This is a powerful API, but it is...

`PngDecoder` supports setting limits via `with_limits` but not via `set_limits`

2

This happens in `image` v0.24.7. ## Expected `PngDecoder` should support setting memory limits via the generic `set_limits` method, not only via its own `with_limits` method. ## Actual behaviour Only the...
