Wrong text color with internal PDF reader (Microsoft PDF export of excel file)

Summary:

I created a test document in Microsoft Excel with various cell border/fill colors and various text colors/fonts/styles, as shown in the following screen capture:

If I create a PDF from Excel using three different methods, all three PDF files render correctly in Adobe Acrobat, but there is variation in how the Inkscape internal PDF reader imports them:

• File > Print > Microsoft PDF print driver

  • text font differences

  

• File > Print > Adobe PDF print driver

  • text color differences

  

• File > Save as > PDF

  • seems to be correct

  

It would be good for the Inkscape internal PDF reader to import PDFs files more closely to how Adobe Acrobat renders them.

Steps to reproduce:

• Download testcase: test.zip
• Open Inkscape.
• Import each PDF file.
• Compare results to PDF viewer or reference screen capture above.

What happened?

For two of the PDF files, the imported PDF contained different formatting:

• File > Print > Microsoft PDF print driver
  • text font differences
• File > Print > Adobe PDF print driver
  • text color differences
