The {{KW|_PIXELSIZE}} function returns the color depth (Bits Per Pixel) of an image.


{{PageSyntax}}
:''return&'' = {{KW|_PIXELSIZE}}([{{Parameter|imageHandle&}}])


{{PageDescription}}
* If {{Parameter|imageHandle&}} is omitted, it is assumed to be a handle to the current write page.
* Returns:
:: 0 if the image or screen page specified by {{Parameter|imageHandle&}} is in text mode.
:: 1 If the image specified by {{Parameter|imageHandle&}} is in 1(B & W), 4(16 color) or 8(256 color) BPP mode.
:: 4 Image specified is a 24/32-bit compatible mode. Pixels use three bytes, one per Red, Green and Blue color intensity.
* The [[SCREEN]] or [[_NEWIMAGE]] or [[_LOADIMAGE]] color(256 or 32) mode can influence the pixel sizes that can be returned.
* If {{Parameter|imageHandle&}} is an invalid handle, then an [[ERROR Codes|invalid handle]] error is returned.
