Review request for Okular.


Repository: okular


Description
-------

This patch implements the feature request of bug 321350: if a PDF file is viewed, the selection tool offers the new extraction method "vector" which allows to save to a file (PDF, SVG, EPS, PostScript). The crop operation is performed by calling "pdftocairo" with matching arguments. The resulting file contains the original PDF file's content without rendering it to a pixmap.

I am not sure if calling an external program is an acceptable solution for this problem. However, it is tested if the program is available before showing the new option. Alternatively, the code of pdftocairo (as part of poppler) would had to be copied and integrated into Okular increasing the solution's complexity. I am not aware of a similar solution available using poppler-qt4 only. Maybe using a QPrinter printing to PDF would have been an alternative, but again this seemed to be too complex.
