Parameters

Name	Explanation
Pal0	The number of 0 pixels retrieved from a 1 bit color image palette.

Explanation

The GetOneBitPalCount method retrieves the number of 0 pixels and 1 pixels from a 1 bit color image. This method is enabled for 1 bit color images only.

When the ImageHandle parameter contains a valid image handle
The image data that the ImageHandle parameter refers to will be processed.

When using the method with no ImageHandle parameter or when the ImageHandle parameter contains 0
The image data determined by the LayerNo property will be processed. If the LayerNo property is -1 (the base image) then the image data referred to by the ImageHandle property will be processed. If the value of the LayerNo property is between 0 and 99 then the image data referred to by the Layer(LayerNo).ImageHandle property will be processed.

For Palette color, please refer to the GetPalette method.
