PDF map file does not load or appears incorrectly.

Purple Pen relies on Google Pdfium to read PDF files. Sometimes badly formed PDF files will not be converted correctly by this program. You can convert these "bad" PDFs to "good" PDFs with the following procedure.

  1. Download and install the free version of PrimoPDF from primopdf.com
  2. Open the "bad" PDF in Adobe Reader.
  3. In Adobe Reader, select "Print..." from the File menu.
  4. In the "Printer" drop-down list at the top, select "PrimoPDF".
  5. In the "Page Sizing & Handling section, click the "Size" button.
  6. Select "Actual Size".
  7. Check "Choose paper source from PDF page size".
  8. Check "Use custom paper size when needed".
  9. Click "Print" buttom.
  10. When the PrimoPDF dialog appears, click "Create PDF" and save the PDF to a new file. This PDF is your "good" PDF that should load correctly into Purple Pen.
