# Objective - Get rid of giant match statement to get PixelInfo. - This will allow for supporting any texture that is uncompressed, instead of people needing to PR in any textures that are supported in wgpu, but not bevy. ## Solution - More conservative alternative to https://github.com/bevyengine/bevy/pull/6788, where we don't try to make some of the calculations correct for compressed types. - Delete `PixelInfo` and get the pixel_size directly from wgpu. Data from wgpu is here: https://docs.rs/wgpu-types/0.14.0/src/wgpu_types/lib.rs.html#2359 - Panic if the texture is a compressed type. An integer byte size of a pixel is no longer a valid concept when talking about compressed textures. - All internal usages use `pixel_size` and not `pixel_info` and are on uncompressed formats. Most of these usages are on either explicit texture formats or slightly indirectly through `TextureFormat::bevy_default()`. The other uses are in `TextureAtlas` and have other calculations that assumes the texture is uncompressed. ## Changelog - remove `PixelInfo` and get `pixel_size` from wgpu ## Migration Guide `PixelInfo` has been removed. `PixelInfo::components` is equivalent to `texture_format.describe().components`. `PixelInfo::type_size` can be gotten from `texture_format.describe().block_size/ texture_format.describe().components`. But note this can yield incorrect results for some texture types like Rg11b10Float. |
