Posting under my real name for once, I will revert to "Le Forgeron" right after.

+FT is already used for Uncompressed Targa 24bits
What about +FA instead (A: Ascii ?)

You do not have to update that code, unless you want more than RGBA in the buffer.
The file interface has only the knowledge of the concept of line.

Look in png_pov.* or targa.* for an example of the functions needed
(one open, one write a line, one read a line, one read full image, one close)
The buffer is there to delay the writing of x lines on the disk, instead
of making a disk access (or rather asking the system to do it) per lines.
Most useful when rendering small width, far less I/O, this keep the CPU working
on the useful things!)
