maketx --alpha1-detect will omit alpha from textures whose input images had designated alpha channels that were 1.0 for all pixels. Somewhat similar in operation to --monochrome-detect and --constant-detect. Also adds ImageBufAlgo::isConstantChannel() utility and does some minor cleanup/simplification to isConstantColor. (Yes, this is because we have textures with pointless alpha=1 everywhere, and it's easier to fix in image-to-texture conversion than it is to actually fix the problem upstream.) -- Larry Gritz [email protected] _______________________________________________ Oiio-dev mailing list [email protected] http://lists.openimageio.org/listinfo.cgi/oiio-dev-openimageio.org
