Bug Description

I use inkscape 0.48 under Ubuntu 10.10.

When I export a file to pdf (file > save as > .pdf), the output file has format PDF-1.5, which wasn't the case in Ubuntu 10.04, where file were exported in pdf 1.4.

The only choice I have when exporting is pdf 1.4, but the output has format pdf 1.5 anyway. I tried to modify org.inkscape.output.pdf.cairorenderer.PDFversion in preferences.xml without success.

Attached is a screenshot showing the export process and the properties of the output file.

There have been no changes in Inkscape with regard to PDF export: it seems that the most recent (stable) cairo version uses PDF 1.5 as default.

Fix in r9841 confirmed with

a) local build on Mac OS X 10.5.8
Inkscape 0.48+devel r9841, cairo 1.8.10: exports PDF 1.4

b) development build from modevia for osx:
Inkscape 0.48+devel r9841, cairo 1.10.0: allows export to PDF 1.4 and PDF 1.5

Don't know if PDF 1.5 has additional or changed features that would need to be addressed on Inkscape's side as well (like for PS/EPS levels, e.g. bug #491590).

~suv asked about PDF 1.4 vs 1.5.

I've found exporting as PDF 1.5 is a problem if you produce files for other people to open using Adobe Acrobat.

I produced a PDF for a client in Inkscape 0.48 that they couldn't open with Adobe Acrobat. FoxPro could import it fine.

I used Inkscape 0.47 to export the same file as a PDF 1.4 on another computer and Adobe Acrobat had no problems understanding this pdf file at all.

@Dave Jeffery - your issue could be a known bug in cairo 1.10 when exporting objects with opaque gradients to PDF:
Bug #681512 “Opaque radial gradients cause PDFs to fail to open in Adobe Reader”
Bug #672686 “Some diagrams results in "Illegal character" in the generated pdf”

Using PDF 1.5 is unlikely to be causing issues with Adobe Acrobat. PDF is designed to be forward compatible. ie if the PDF file contains features that the reader does not know about, those features are ignored while the rest of the file displays correctly. The PDF 1.5 features that cairo supports are not used by Inkscape so even though the version in the file is 1.5 it is only using 1.4 features.

Only very old versions of Adobe Acrobat don't support PDF 1.5.
  Acrobat 5 (2001) -> PDF 1.4
  Acrobat 6 (2003) -> PDF 1.5
  Acrobat 7 (2005) -> PDF 1.6
  Acrobat 8 (2006) -> PDF 1.7
  Acrobat 9 (2008) -> PDF 1.7 + extensions

There are many other differences between 0.47 and 0.48 that could be the cause of your bug. Usually problems with opening PDF files are a cairo bug since cairo should never generate an invalid PDF file (unless cairo returns an error status).

Proposing to backport since Windows and Mac OS X packages will ship with cairo > 1.10, too.

@JazzyNico - are there any solutions to backport this nevertheless?

jazzynico (jazzynico) wrote :

@~suv - IIRC, the change is not too drastic. Thus it's possible to keep the old label, and as the new value is just the PDF version, we can keep it untranslated.

Option label changes (very minor) not backported.
