GtkColor RGB values are uint16s that range from 0-65,000+, so I'm afraid that these values are too big. Is there a way to convert a gint16 into a guint8 correctly?

If there are 256 variations of a color element, and it's represented by a range of 0 - (256*256) then each step of color has a value of 256. So, a value of 0 - 255 is actually 0, 256 - 511 is actually 1, etc. Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         GTK+ Forums Forum Index -> GTK+ Programming All times are GMT Page 1 of 1 Powered by phpBB © 2001, 2005 phpBB Group CodeBB 1.0 Beta 2 Protected by Anti-Spam ACP
