Overprint support in PDF rasterizer: Missing text when converting PDF to JPEG

Q: Hi – I have a PDF page that loses some text when converting PDF to
JPEG. The text is visible when overprint support is disabled, however
I need overprint support.


A: The problem is with overprint settings (which is most likely set to
true). To achieve results that are consistent with Acrobat, you should
use the latest version of PDFNet (http://www.pdftron.com/pdfnet/
downloads.html) and use
pdfdraw.SetOverprint(PDFRasterizer.OverprintPreviewMode.e_op_pdfx_on).
This option enables overprint support only for PDF/X documents (i.e.
which is default Acrobat setting).
