- ======
-
- Version 1.50 (21-Jun-1993)
- SPRtools block 1c release.
- (C) 1993,4 DEEJ Technology PLC
-
- Features
- --------
- Sprite mode changer.
- Can be used to change unknown mode number to ones that the SPRtools
- understand.
-
- Restrictions
- ------------
- chmode only changes the mode number stored in the sprite, it does not
- alter the bits per pixel of the image.
-
- SPRtools will only understand RISC OS 3.1 modes, modes from the DEEJmodes
- module and the new RISC OS 3.5 mode specifiers.
-
- User defined modes may differ from SPRtools modes, and old applications may
- not understand 1-8 bpp sprites using RISC OS 3.5 mode specifiers. Use
- chmode to change the sprite to an appropriate alternative mode.
-
- Only the first sprite in the file is recognised.
-
- Syntax
- ------
- chmode <sprite file> {<mode> | {<type> <xres> <yres>}}
-
- where: <mode> mode number.
