Hi Performers,

I would like to know if performer offers a similar feature like the Opengl
Imaging Extension for Color Table, SGI_color_table.

I'd like to map video as a texture, but before mapping it, I would like
to scale/bias the image to suit some brightness/contrast requirements. I
presume this can be done using the Color_table extension in Opengl. How
can I possibly do it using performer.

Will I be able to use the PFTEX_MAGFILTER_COLOR filter for pfTexture to
control the brightness of the image?

Also, I would like to know how color keying can be done on video textures
using performer. I'm extracting video using DIVO and would like to do some
color keying on the video before texturing it.

Thanks,
Satheesh
