Subject: inkscape: rasterizing effects when exporting from the commandline
Date: Wed, 25 May 2011 23:10:52 +0200
Package: inkscape
Version: 0.48.1-2
Severity: normal

hi,

when exporting from the commandline to pdf, ps or eps it seems not to
be possible to select to raster effects (as it is possible from the
gui), but instead the effected objects are just left out from the export
(unless of course you use --export-ignore-filters, but the you loose the
effects).

this decreases the usefullness of inkscape in batch mode.

yours,
albert

Not reproduced with Inkscape 0.48.1 and current stable (Inkscape 0.48.3.1) using a simple test file with a blurred circle:
command line export to PDF always exports filter effects rasterized unless explicitly disabled with '--export-ignore-filters', as described in the man page and in the release notes about the initial implementation of cairo-based exports to PDF/PS/EPS [1]. With the simple test case, the object from the SVG file is present in the PDF file with both export methods (GUI, command line).

> (…) but instead the effected objects are just left out from the export

The identical file, with exactly the same export options as used in the GUI? Odd. If objects are missing completely in the generated PDF, this is very likely not a failure of exporting via command line (as opposed to using the GUI), but due to hitting a memory limitation while generating huge bitmaps in memory during the export (see bug #494115).

Could you please attach a sample file which triggered the reported issue, to allow further investigation?
