{{PageDescription}}
|
|
* Palette Intensity settings are '''not''' used by 24/32 bit images. Use only with 4 or 8 BPP images.
|
|
* [[_PIXELSIZE]] function returns 1 to indicate that _COPYPALETTE can be used. 4 indicates 24/32 bit images.
|
|
* If {{Parameter|sourceImageHandle&}} is omitted, it is assumed to be the current read page.
|
|
* If {{Parameter|destinationImageHandle&}} is omitted, it is assumed to be the current write page.
|
|
* If either of the images specified by {{Parameter|sourceImageHandle&}} or {{Parameter|destinationImageHandle&}} do not use a palette, an [[ERROR Codes|illegal function call]] error is returned.
|
|
* If either {{Parameter|sourceImageHandle&}} or {{Parameter|destinationImageHandle&}} is an invalid handle, an [[ERROR Codes|invalid handle]] error is returned.
|
|
* When loading 4 or 8 BPP image files, it is necessary to adopt the color palette of the image or it may not have the correct colors!
