IG_dspl_palette

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.

Declaration:

AT_ERRCOUNT ACCUAPI IG_dspl_palette_create( [IN] HIGEAR hIGear, [IN] DWORD dwGrpID, [IN] HWND hWnd, [IN] HDC hDC, [OUT] HPALETTE FAR* lphPalette );

Arguments:

Name	Type	Description
hIGear	HIGEAR	ImageGear handle of image.
