ImageGear for C and C++ on Linux v20.0 - Updated
API Reference Guide > Core Component API Reference > Core Component Functions Reference > Display Functions > IG_dspl_palette_create

This function calculates all the display parameters, the way IG_dspl_image_draw() does, and produces the same palette that IG_dspl_image_draw realizes before drawing onto hDC; it returns DevicePalette if it is not set with a custom value.
