pdfGetNumColorSpaces
Get the number of PDF color space types.
int pdfGetNumColorSpaces(PDFHandle pdf)
The available color space types are defined by the PDF
specification. As of PDF 1.7, they are:
- DeviceGray
- CalGray
- DeviceRGB
- CalRGB
- DeviceCMYK
- Lab
- ICCBased
- Indexed
- Separation
- DeviceN
- Pattern
pdfGetNumColorSpaces and pdfGetColorSpaceName
functions return the items in the list above. (In general, that list
won't change - i.e., pdfGetNumColorSpaces and
pdfGetColorSpaceName 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 pdfGetImageInfo function returns a color space type, which is
an integer in 0 .. n-1, where n is the value returned by
pdfGetNumColorSpaces.
C:
char *name;
int i, n;
n = pdfGetNumColorSpaces(pdf);
for (i = 0; i < n; ++i) {
name = pdfGetColorSpaceName(pdf, i);
printf("color space type %d: %s\n", i, name);
}
