Loading texture from tiff images

[edmBernard]

I try to load texture from tiff image.
and I got the following error :
no `AssetLoader` found for the following extension: tiff
After some search I found that bevy have a ImageTextureLoader that should support all format supported by the crates image.
But I have no clue how to use it.
I also found that we can create bevy Image from DynamicImage (image-rs format).
I haven't found how to put the texture on a sprite without the asset-server.
Does someone have an idea ?

You have to add the tiff feature to bevy

[edmBernard]

There is no tiff feature in bevy : https://github.com/bevyengine/bevy/blob/HEAD/docs/cargo_features.md

I try to enable all features, it seem that if I enable bevy_render I can read "tiff" image not "tif" and only tiff in 8bit RGB.
We can't read tiff in 16UInt and tiff 8bit Palette (the 8b Palette is not supported by the crates image so I don't expect it's support).

Then there is probably no current way to enable it. You could make a pr introducing it as a feature when you are sure that there would be no problem in the bevy code and the image library could handle it fine

I found a way to make it work, It's manual.
I use the method shown here https://www.reddit.com/r/bevy/comments/y5fzkl/how_to_get_a_texture_from_a_in_memory_image_not_a/
I manually load the image with image-rs and send the handle to the texture.

the issue with 16U is the wgpu doesn't seem to support this format for texture.
with the manual load I can convert 16u image to 8u on the loading code.
thanks for the help
