- DIF 1.0 © 1995 Jonathan Potter
-
- This is a little program designed to allow easy conversion of images
- designed for one screen depth to images suitable for another screen depth.
- For example, the Magic Workbench icons for DOpus 5 (by Trevor Morris &
- Leo Davidson) are all designed for an eight colour screen. If your DOpus
- screen (or Workbench screen) is more than eight colours, these images will
- be displayed in the wrong colours. DIF can remap these images to allow
- their use on a deeper screen.
-
- Usage : DIF FROM/A,TO/A,DEPTH/N/A
-
- FROM - source image file
- TO - destination image file
- DEPTH - desired depth of the converted image
-
- The input file must be an IFF ILBM image. You will normally specify the
- depth of your Opus (or Workbench) screen for DEPTH - for instance, my
- Workbench screen is 32 colours, so I would specify a DEPTH of 5
- (if you don't understand the term "depth", tough luck :)
-
- While this program will work on any depth source image, and produce any
- depth destination image, it is really designed for converting 8 colour
- images to work on a screen of more than 8 colours. For that reason, the
- results when using any other depth input image are undefined (well, they're
- not undefined, but I've never tried it, so who knows what will happen :)
- You can also specify a smaller depth than the original image, in which
- case the higher bitplanes will simply be tossed away.
-
- The easiest way to use this program is probably to set up a DOpus button,
- with a function similar to the following :
-
-
- AmigaDOS DIF {fu} {d}{o} {RsEnter desired depth:4}
-
- Flags : Do all files
- Output to window
- Rescan dest
- Window close button
-
-
- DIF works on both RLE-compressed images and non-compressed images
- (like brushes).
