Update of /cvsroot/pure-data/externals/gem2pdp
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv19404
Modified Files:
pdp2gem.cpp pdp2gem.h
Log Message:
added colorspace message which allows us to select the destination colorspace (YUV, RGB/BGR, RGBA/BGRA); now uses GemPixUtils color conversions to centralize the code
