TIFFframes is a very simple NeXTStep utility useful for creating
24-bit TIFF images from 3 separate 8-bit files, which store
the red, green, and blue components separately with no header
information. If you have an animation sequence of such bitmaps,
just add a frame number extension to each file. For example,
redfile.1, greenfile.1, bluefile.1, redfile.2, greenfile.2, etc.
The program will then produce myMovie.1.tiff, myMovie.2.tiff, etc.,
and if you store these in a directory called myMovie.anim, then
you can just double-click to view it in Patrick Flynn's Movie app.
TIFFframes can also be useful if you have an image format
not currently handled by Lennart Lovstrand's free "ImageViewer"
or a commercial app such as PixelMagician. As an alternative to
figuring out how to read the image header structure, just use
the unix utility 'dd' to strip the raw bitmaps out of the file,
and then use RGBtoTIFF. [Do 'man dd' to find out how, and see
the help panel in RGBtoTIFF.] I'm including the source here, in
case you want to change the defaults, or find out how to do
histogram equalization, or how to tell an NXImage to "writeTIFF". ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
