Grabs a specified part of the currently active palette. The format is the same as for setPalette.
This should return exactly the same RGB data as was setup via previous setPalette calls.
For example, for every valid value of start and num of the following code:
byte origPal[num*3]; // Setup origPal's data however you like g_system->setPalette(origPal, start, num); byte obtainedPal[num*3]; g_system->grabPalette(obtainedPal, start, num);
the following should be true:
memcmp(origPal, obtainedPal, num*3) == 0

- setPalette
- Parameters
-
colors | the palette data, in interleaved RGB format |
start | the first platte entry to be read |
num | the number of palette entries to be read |
- Note
- It is an error if this function gets called when the pixel format in use (the return value of getScreenFormat) has more than one byte per pixel.
