numColorSpaces

Get the number of PDF color space types.
[read-only property] numColorSpaces([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 XpdfAnalyze will be updated to match.)

The getImageInfo function returns a color space type, which is an integer in 0 .. n-1, where n is the value of the numColorSpaces property.

VB6:
n = pdf.numColorSpaces For i = 0 To n-1 name = pdf.getColorSpaceName(i) MsgBox "color space type " & i ": " & name Next i
getColorSpaceName
