From your pod info it seems its running on ARM devices, the architecture is: `AArch64`. We heavily rely on hardware intrinsics only available for x86/x64 (SSE, AVX) for speed, with...

@christallire you can do more then just poking. This is a open source project. You can make it better by opening Pull requests. The webp implementation is based on libwebp....

@dfornero the images you have provided are jpg images and not tiff images.

@CREFaulk without the image, it's nearly impossible to tell what's wrong (I guess something goes wrong while decoding). What happens, when you convert the image to a png with imagemagick?...

Thanks for the image info. Nothing too fancy there. Endianess is lsb, tiff:photometric: min-is-black and compression is group4. We have such test images in our unit tests working. > If...

Closing this now, because without a test image this can not be reproduced. @CREFaulk feel free to open/comment here again, if you manage to get a image with that issue...

@antonfirsov with #1734 merged, encoding with RGB colorspace is now possible.

What would be a solution to fix this issue? - Use `VerifyEncoder` in `TestPngEncoderCore` and delete the PngEncoder reference images or - Assume the reference images are correct and use...
