select_palette - Man Page

#include <allegro.h>

void select_palette(const PALETTE p);

Ugly hack for use in various dodgy situations where you need to convert  between paletted and truecolor image formats. Sets the internal palette  table in the same way as the set_palette() function, so the conversion  will use the specified palette, but without affecting the display  hardware in any way. The previous palette settings are stored in an  internal buffer, and can be restored by calling unselect_palette(). If you call select_palette() again, however, the internal buffer will be overwritten.
