Is there such a beast working?

yup: just committed it to cvs, and also put a pre-compiled version on my ugly website:

notes from the readme:

notes:

• now allows you to select the colorspace that pdp's yv12 image format

is converted to. This means we can now request a YUV colorspace, which is computationally much faster than yv12 to RGB or RGBA (so much so that it is the default). Colorspace can be indicated on object creation (ie. [pdp2gem RGB]) or by message (ie. [colorspace YUV<)

• now uses standardized color conversions found in GemPixUtil.cpp,

which includes altivec speedups! These use formulae from http://www.poynton.com/notes/colour_and_gamma/ColorFAQ.html#RTFToC30

• please note that colorspace switching between objects is handled

automatically by GEM unless specifically stated (ie. by [pix_yuv], [pix_rgba], [pix_grey])

enjoy!
