It's not a matter of length but a matter of descriptiveness: right now there is only one single different whitepoint defined by DCI, so IMO it makes sense to call it simply WP_DCI. In case DCI adds new values, naming can be modified later. The other whitepoints could also have longer, more descriptive names too, like WP_ILLUMINANT_C, but at the same time the WP_C shorthand is convenient and immediate (and IMO better suited as variable name). At any rate, pick the one you prefer ;) -- Vittorio _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
