# Objective
- Fixes https://github.com/bevyengine/bevy/issues/17891
- Cherry-picked from https://github.com/bevyengine/bevy/pull/18411
## Solution
The `name` argument could either be made permanent (by removing the
`#[cfg(...)]` condition) or eliminated entirely. I opted to remove it,
as debugging a specific DDS texture edge case in GLTF files doesn't seem
necessary, and there isn't any other foreseeable need to have it.
## Migration Guide
- `Image::from_buffer()` no longer has a `name` argument that's only
present in debug builds when the `"dds"` feature is enabled. If you
happen to pass a name, remove it.
# Objective
I was setting up an asset loader that passes settings through to
`ImageLoader`, and i have to clone the settings to achieve this.
## Solution
Derive `Clone` for `ImageLoaderSettings` and `ImageFormatSetting`.
## Testing
Full CI passed.
# Objective
- Remove `derive_more`'s error derivation and replace it with
`thiserror`
## Solution
- Added `derive_more`'s `error` feature to `deny.toml` to prevent it
sneaking back in.
- Reverted to `thiserror` error derivation
## Notes
Merge conflicts were too numerous to revert the individual changes, so
this reversion was done manually. Please scrutinise carefully during
review.
Resolves#15968. Since this feature never worked, and enabling it in the
`image` crate requires system dependencies, we've decided that it's best
to just remove it and let other plugin crates offer support for it as
needed.
## Migration Guide
AVIF images are no longer supported. They never really worked, and
require system dependencies (libdav1d) to work correctly, so, it's
better to simply offer this support via an unofficial plugin instead as
needed. The corresponding types have been removed from Bevy to account
for this.
# Objective
- This is a followup to #15812.
## Solution
I just deleted the `COUNT` const and replaced it. I didn't realize for
loops are not const yet, so improving the other const variables is not
obvious.
Note: `slice::len` has been const since Rust 1.39, so we're not relying
on a brand new feature or anything.
## Testing
- It builds!
# Objective
Fixes#15730.
## Solution
As part of #15586, we made a constant to store all the supported image
formats. However since the `ImageFormat` does actually include Hdr and
OpenExr, it also included the `"hdr"` and `"exr"` file extensions. These
are supported by separate loaders though: `HdrTextureLoader` and
`ExrTextureLoader`. This led to a warning about duplicate asset loaders.
Therefore, instead of having the constant for `ImageFormat`, I made the
constant just for `ImageLoader`. This lets us correctly remove `"hdr"`
and `"exr"` from the image formats supported by `ImageLoader`, returning
us to having a single asset loader for every image format.
Note: we could have just removed `hdr` and `exr` from
`ImageFormat::SUPPORTED_FILE_EXTENSIONS`, but this would be very
confusing. Then the list of `ImageFormat`s would not match the list of
supported formats!
## Testing
- I ran the `sprite` example and got no warning! I also replaced the
sprite in that example with an HDR file and everything worked as
expected.
# Objective
This is a follow-up to #15650. While the core `Image` stuff moved from
`bevy_render` to `bevy_image`, the `ImageLoader` and the
`CompressedImageSaver` remained in `bevy_render`.
## Solution
I moved `ImageLoader` and `CompressedImageSaver` to `bevy_image` and
re-exported everything out from `bevy_render`. The second step isn't
strictly necessary, but `bevy_render` is already doing this for all the
other `bevy_image` types, so I kept it the same for consistency.
Unfortunately I had to give `ImageLoader` a constructor so I can keep
the `RenderDevice` stuff in `bevy_render`.
## Testing
It compiles!
## Migration Guide
- `ImageLoader` can no longer be initialized directly through
`init_asset_loader`. Now you must use
`app.register_asset_loader(ImageLoader::new(supported_compressed_formats))`
(check out the implementation of `bevy_render::ImagePlugin`). This only
affects you if you are initializing the loader manually and does not
affect users of `bevy_render::ImagePlugin`.
## Followup work
- We should be able to move most of the `ImagePlugin` to `bevy_image`.
This would likely require an `ImagePlugin` and a `RenderImagePlugin` or
something though.
