Hello,
Despite reading several posts in the archive and the source code in g_all_guis.c I am embarrassed to say that I am completely stumped by the problem of extracting the individual RGB components from the IEM saved color value in the .pd file, as ints between 0 and 255.
What I am doing (in the case where the saved value is negative) is:
iemcolor = -1 - iemcolor;
r = (iemcolor & 0x3f000) >> 14;
g = (iemcolor & 0xfc0) >> 4;
b = (iemcolor & 0x3f) << 2;
I would really appreciate it if someone gave me the opportunity to facepalm by illustraing the simple mistake in my approach.
Cheers!
Chris.
