ColorMatrix for Squeak

All,

did anybody implement a ColorMatrix class for 32bit ARGB forms? I need
to apply things like hue and saturation changes to forms ... and before
doing this for each operation manually I think using a appropriate Color
matrix makes more sense.

Any pointers?

Regards,

Udo

Video and Image Processing framework is maybe what you look for.

I'll take a look a this again. Last time I tried I neither could install
the SqueakMap version not the archive into a virgin 3.9 image. However
from the description on the website (which does not mention hue changes)
I assume the brightness and contrast filters are simply based on
changing the RGB components .... not using a ColorMatrix.

CU,

Udo
