PDF export doesn't parse gradients

Summary:

When exporting a .SVG file as a .PDF, the gradients are exported in a apparently wrong form that can only be read by Inkscape, which "violates" the predictability of the PDF standard. File: sun_exported_inkscape.pdf

Illustrator, for example, can also export from .SVG to .PDF (without the .ai data) while maintaining gradient compatibility. So it's not a limitation of the PDF standard, apparently. File: sun_exported_illustrator.pdf

Steps to reproduce:

  • open Inkscape.
  • export svg with gradient as pdf
  • open in another program (eg Illustrator)
  • observes lack of compatibility

What happened?

The file can be opened, but the gradients are rasterized.

What should have happened?

The file can be opened in both Illustrator and Inkscape with the gradients retained.
