wrong image color about fast_image_resize HOT 10 CLOSED

The original image contains Display P3 color profile. The result image doesn't contain it.
The fast_image_resize knows nothing about color profiles or color spaces. It works with raw pixel values.
If you want to get correct colors, you should at least add the color profile from the source image-file into the result image-file.
Ideally, you should convert the source pixels to a linear color space before resizing, and convert them back after resizing (read more)

can you suggest library for do this ?

Honestly, I don't see any difference in the color of these images on my computer.

But I see that you used Nearest algorithm to resize the image.
That is the result of using Convolution(Filter::Lanczos3) algorithm:

And if you also resize the image in linear color space (with mapper that may be created with help of create_srgb_mapper()), the result in dark areas will be even better (look at the grass under the bull):

1. Your result with Nearest algorithm
2. Resize with Convolution algorithm in sRGB color space
3. Resize with Convolution algorithm in linear color space

I opened the original image in my browser and now I see the color difference. I think my default image viewer doesn't support color profiles. And that's the reason why I didn't see the difference at first.

can you suggest library for do this ?

Sorry, I can't suggest any library right now. I haven't had to work with color profiles yet.

ok, thank you.

The first crate I found on google was https://github.com/kornelski/rust-lcms2.
