RE: Do I want it?

Dear Fred,

My first reaction was "wow."

I've been studying computer graphics since 1980, and I have always used
"raster" and "bitmap" interchangeably. You are the first person who
pointed this out. Besides Adobe, does anyone else use this distinction?
If anyone has a reference, please e-mail me.

Raster was the original term used. I think that bitmap is a lot more
descriptive, and doesn't carry the CRT "baggage" of raster.

Joe

One small quibble, Joe:
Many authorities and many graphics applications make a distinction
between raster images and bitmap images. (I was once scolded on the
FrameUsers list by someone from Adobe for incorrect usage of "bitmap",
so maybe I'm over-sensitive on this...)  In the traditional usage, a
bitmap image is a raster image with a 1-bit depth; i.e. pure black and
white rather than grayscale or color. Raster is the more general term
which can properly be used with any type of bit-by-bit image.
