- Poor Man's TIFF Editor

-
- This is a rough-and-ready two-level black-and-white pixel graphics
- editor... Well, not quite even that.
-
- It is a very simple means of editing a graphics file you have on disk in
- TIFF format. It converts the TIFF file into a (possibly Gargantuan) text
- file, which you can edit using your favourite text editor, and then
- converts the result back into a TIFF file. Easy, ne?
-
-
- Hence, the editing process has three stages:
-
- (1) TIFF2CHR < tiff-file > text-file
- where "tiff-file" has been replaced by the name of your TIFF file,
- complete with extension, and "text-file" by some new name.
-
- (2) Use your text editor, or word processor, to manipulate the file
- created by (1) above. Or print it, probably using the smallest font
- available on your printer. Then save the text file; make sure the
- output is plain ASCII and contains no word processor information.
- (For the contents of the first line, cf. below.)
-
- (3) CHR2TIFF < text-file > new-tiff-file
- where "text-file" is the name of the file written in (2) above, and
- "new-tiff-file" is a file with extension TIF. You may want to use a
- new name for this, just to make sure.
-
-
- That's it!
-
-
- A few more remarks:
-
- The first line of the text file contains the picture's dimensions, first
- width, then height. This gives you control over the resulting picture's
- size. If you change just a few pixels, you'll probably want to leave the
- size values unchanged; but you can use them to trim off excess space on
- the right and the bottom.
-
- If your picture is smaller than the sizes specified, blank space will be
- padded.
-
- The rule is that each character in the text file corresponds to one
- pixel. Black pixels correspond to the space character; white pixels are
- mapped to asterisks by TIFF2CHR. CHR2TIFF, on the other hand, will
- accept all non-blank characters for white pixels.
-
- Note that the text file can be quite large, so your editor/word
- processor must be able to handle large files.
-
- Error handling is only rudimentary; beware of full disks.
-
- For the technically-minded: TIFF2CHR can read run-length encoded TIFF
- files, but none of the more sophisticated compressed formats. CHR2TIFF
- will always produce unpacked files.
-
- Colour and greyscale TIFF files are not supported by POMTED 1.0, nor
- will they ever be. If you want something more sophisticated, use a more
- sophisticated programme.

- copyright.
