Hi, I'd like to use this to resize images with accurate gamma, which I would do by first converting to RGB, then resizing, then converting back to sRGB. However, using the Q8 version can result in severe colour issues because Q8 doesn't have enough precision for the conversion. Is there any chance of a Q16 version?

I'm doing:

image.colorSpace = ColorSpace.RGB;
image.resize(1200, 800);
image.colorSpace = ColorSpace.sRGB;

Which gives the same results as -colorspace RGB -resize 1200x800 -colorspace sRGB in the Q8 command line version.

Right now there are no concrete plans for a Q16 or Q16-HDRI version. This was not done because wasm is only 32-bit right now. There is a 64-bit option but that used to be experimental. It no longer is experimental so I might play around with that in the future. And then I will need to figure out how to make this work with different versions of the .wasm file.

Just to note, an alterntive package uses Q16:

I am seeing x64 wasm more often so I think that I should play around with that in the couple months
