Get the number of objects drawn in a particular color space type.
getNumColorSpaceObjects([in] int page, [in] int idx, [out, retval] int *n)
The available color space types are defined by the PDF specification. As of PDF 1.7, they are: The numColorSpaces property and getColorSpaceName function return the items in the list above. (In general, that list won't change - i.e., numColorSpaces and getColorSpaceName will always return the same values - but future revisions to the PDF spec may add color space types, and XpdfRasterizer will be updated to match.)

The getNumColorSpaceObjects function will return the number of objects drawn in a specified color space type on a specified page.

n = pdf.numColorSpaces For i = 0 To n-1 name = pdf.getColorSpaceName(i) count = pdf.getNumColorSpaceObjects(page, i) MsgBox count & " objects drawn in the " & name & " color space type" Next i
