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.

For example:

3 3
255

170 135 105  100 69 38  150 121 89
175 138 111  102 66 40  155 121 93

162 122 97 107 70 44 131 94 68
------

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).
