Thanks Ismael, Peter and I have been using imageoptim for the last few months, but I know not all the graphics been compressed since many are older. It would be great to have scripts like this run when the build is being compiled.
I can also see the value of one that would dither files with gradients for lower colour bit depth screens… ie. if we added _dither to the graphic file name, the script would dither that file to a specific variable, so in devices with 16bit colour we can dither gradients while on devices with 24bit colour we would not run that script. That would allow us to have 1 version of the graphic files and optimize the quality for 2 devices. -- Patryk Adamczyk, R.G.D.
