A shade of gray is made by having r == g == b. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of D. Hartley Sent: Tuesday, May 10, 2005 4:46 PM Cc: tutor@python.org Subject: Re: [Tutor] zip question
I tried to look at the image band by band, but got three grey-scale-looking images (for r, g, and b), and one white one. I have a feeling my clue lies in the latter, but am having a hard time finding examples of how to manipulate that part (trying hard to avoid a spoiler here!) in the documentation. Any pointers?
