#X text 14 76 [pix_chroma_key] does compositing using pixel by pixel comparisons on two video streams. the comparison is based on user a user supplied RGB or YUV pixel value and +/- range. if the pixel in the key source lies within the range \, then it is replaced by the corresponding pixel im the other stream. typically this is most effective on a static background like a green/blue screen \, but can be effective when used with other GEM objects like pix_background for live video processing.;
