ColourTrans_ ReadPalette
(SWI &4075C)
| Entry | |
|---|---|
| R0 | Source mode |
| R1 | Source palette pointer |
| R2 | Pointer to buffer, or 0 to return size needed in R3 |
| R3 | Size of buffer (if R2 is non-zero) |
| R4 | Flags (only used if R0 >= 256) |
| Exit | |
|---|---|
| R2 | Incremented by words written |
| R3 | Remaining size of buffer |
Use
The purpose of this call is to read either the screen’s palette, or a sprite’s palette.
Notes
All entries are returned as true 24-bit RGB, calibrated if required.
In 256 colour modes the full 256 palette entries are returned, rather than the 16 used by VIDC 1.
