1. Pixmap "depth"
Hello all!
Graphics is not my fort=E9, but I'm having to wrap some graphics functions=
=20
for a library that I'm working on. One of these functions returns the=20
"depth" of a pixmap.
Could someone please define the meaning of a pixmap's depth? During=20
testing, I tried two different images ... one, a pixmap icon, and the=20
other, a JPEG image from my digital camera. Both reported a "depth" of=20
16. Because I don't know what "depth" means, I can't tell whether that=20
is the right answer, or whether I screwed something up.
Thanks,
Travis Beaty.

Number of bits per pixel.
A depth of 1 would be black or white, 8 would 1 of 256 colors, etc.
You can create and save a test image in various BPP using most graphics
programs.

Perhaps they mean color depth? 2, 8, 16, 256, or 24-bit (16 million) colors.
Its only a suggestion but it might be right.

Hello Irv.
Super, thanks.
I checked out the digital camera image I tested with, and found that the
depth is indeed 16.
I've also changed a few settings on my email client (Thunderbird), to
see if I can get all those darn "=20"s out of my email. Sorry about
that mess, folks.
Travis.
