All,

Is it possible to build an image one pixel at a time, e.g. to have a data
structure that looks like this:

$i{channel}[x][y]

.... where channel is r,g,b, or a, and x and y are the pixel coordinates.
Then, once I have the data filled out, call some module and write out a .png
file?

My Vulcan mind-reading is not working today. Could you please include
some code?

Confusion is the first step of understanding.

Programming is as much about organization and communication
as it is about coding.

The secret to great software: Fail early & often.

Eliminate software piracy: use only FLOSS.

I don't have any yet. I was just wondering if there was a module that would
write out .png files reliably...

There's a number of them. Try GD to start.
