* 'cupsRasterInterpretPPD()' - Interpret PPD commands to create a page header.
*
- * This function does not mark the options in the PPD using the "num_options"
- * and "options" arguments. Instead, mark the options prior to calling
- * cupsRasterInterpretPPD() - this allows you to do per-page options
- * without manipulating the options array.
+ * This function is used by raster image processing (RIP) filters like
+ * cgpdftoraster and imagetoraster when writing CUPS raster data for a page.
+ * It is not used by raster printer driver filters which only read CUPS
+ * raster data.
+ *
+ *
+ * @code cupsRasterInterpretPPD@ does not mark the options in the PPD using
+ * the "num_options" and "options" arguments. Instead, mark the options with
+ * @code cupsMarkOptions@ and @code ppdMarkOption@ prior to calling it -
+ * this allows for per-page options without manipulating the options array.
*
* The "func" argument specifies an optional callback function that is
* called prior to the computation of the final raster data. The function
- * can make changes to the cups_page_header2_t data as needed to use a
+ * can make changes to the @link cups_page_header2_t@ data as needed to use a
* supported raster format and then returns 0 on success and -1 if the
* requested attributes cannot be supported.
*
- * cupsRasterInterpretPPD() supports a subset of the PostScript language.
- * Currently only the [, ], <<, >>, {, }, cleartomark, copy, dup, index,
- * pop, roll, setpagedevice, and stopped operators are supported.
