#200 pix_resize doesn't work with yuv colourspace

[Anonymous]

pix_resize donesn't resize an image with yuv colourspace. It still passes the image but with original size.

I dont know the Gem vertion but it is the one from Pd-Extended 0.43.1.extended-20120502

that's most likely true.
[pix_resize] uses gluScaleImage() internally, which might not have support for exotic colorspaces like YUV.
gluScaleImage() is probably not the most efficient scaler anyhow, so we might want to consider replacing it with a self-written one, that supports all of Gem's colorspaces.

Please provide as detailed information as possible including which operating system (OS), CPU type, specific hardware, and the exact distro and version of Pd itself, as well as the exact version of Gem, etc.
If you are using Pd-extended (which comes with Gem installed), you still ought to provide the version-number of Gem (as printed out on the Pd-console).

For example:
> Mac OS X 10.5.7/Intel
> Pd version 0.41.4-extended
> Gem 0.93.3 (as packaged with PdX)
> installed video backends: darwin, VLC
> installed movie backends: none
> installed image loaders: QT, ImageMagick

nevertheless it would be interesting to know on which platform the problem appears (or put otherwise: whether gluScaleImage() provides YUV-support on OSX)
