- 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". ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
