Hello - I have a need to create TIFF files from plain ascii text. I would appreciate it if someone could point me in the right direction here. Thanks in advance for any and all assistance.
PPM is pretty much plain ascii text. You could write a PPM file then use netpbm or similar to convert to tiff.

This is a 3x3 pixel image, where each pixel is 8-bit RGB. The "255" is the image's maximum value (always 255 for 8-bit data).
