Subject: [9fans] point2rgb and point2rgba
Date: Mon, 31 Jan 2005 07:54:59 -0700 [thread overview]
Message-ID: <673bb0f7f7be8c76f1db56fb175f06a9@plan9.ucalgary.ca> (raw)
would anyone strongly object adding two routines to query a pixel's
rgba values from an Image*? i know one can do it going through
Memimage's, but drawing memimages on screen is painful to watch.
here are the prototypes:
point2rgb(Image *, Point, uchar *r, uchar *g, uchar *b)
point2rgb(Image *, Point, uchar *r, uchar *g, uchar *b, uchar *alpha)
s/uchar/int/ if you think it's better...
