Subject: [9fans] point2rgb and point2rgba
Topicbox-Message-UUID: 39d92528-eace-11e9-9e20-41e7f4b1d025

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...
