Misplaced elements when converting from svg to wmf

[markus haider]

Binary package hint: python-uniconvertor

When converting the enclosed svg file into wmf, labels at the axes of the graph get displaced. I experienced this using the python-uniconvertor package (1.1.4) as well as uniconvertor build from svn (1.1.5 prerelease).

As wmf/emf seems to be the only vector format open office supports (except from odg), it would be great if this could get fixed.

By the way, http://sk1project.org/modules.php?name=Products&product=uniconvertor&op=devres it is stated that launchpad is the official bug-tracker...

clarification added by ~suv: the link at the UniConvertor Developer Resources page points to their own, so far unused launchpad bugtracker, not to the one from Inkscape.

I get the same result when converting with inkscape, which uses uniconvertor as far as I know for conversion...

[Alvin Penner (apenner)]

this is a uniconvertor bug, not an Inkscape bug, I encounter the same problem when I use uniconvertor 1.1.3 from a DOS prompt.

as a temporary workaround, have you tried emf? attached is the emf obtained from Inkscape 0.47pre4 in Windows XP.

[su_v (suv-lp)]

changing status to 'Invalid' in Inkscape since
a) the source file was created with 'matplotlib' not Inkscape
b) as confirmed by Alvin Penner it also happens when using UniConvertor on the command line outside of inkscape

[markus haider (markus.haider)]

Unfortunatly, the Linux version of Inkscape 0.47pre4 r22446 (which I use) is not capable of exporting into emf. If emf export gets possible, my problem would be solved

I am aware that this is a uniconvertor bug, I just wanted to point out, that this also affects inkscape.

[su_v (suv-lp)]

UniConverter is currently used by Inkscape as helper application for these extensions:
input: ccx, cdr, cdt, cgm, cmx, plt, sk1, wmf
output: plt, sk1, wmf
Bug reports (in Inkscape but concerning UniConvertor) have been filed about CDR import and WMF export, mainly concerning text or unsupported svg elements.

Maybe a RFE for improved or easier data exchange with OpenOffice.org (cross-platform) would be more rewarding to open a discussion about the issue? Are there no plans by OOo to fully support SVG or third-party plugins available (like for PDF)?

[markus haider (markus.haider)]

I completely agree, the main problem is that openoffice does not support svg, eps or pdf, and openoffice is the place where this should be fixed. However, I don't see a solution there in the near future:

There actually is a svg import filter, however it doesn't seem to work very well (see attached screenshot, where I imported my initial svg file). As far as I know, it translates svg into odg, therefore I think this filter will have problems for quite some time. I think the inability to display svg or eps/pdf files is really a problem which should be solved.

I also tried the pdf import filter from the open office extensions, but it also doesn't display the graph right

Confirmed on Ubuntu 9.10, UniConvertor 1.1.4.

Please test svg import filter for uniconvertor correcting this error. To do this, just replace the file in the attachment to the message.

[markus haider (markus.haider)]

@max: I tried your svgloader.py and It worked perfectly, as you can see in the attachment. I wish all bugs could be resolved so fast...

Thanks for the great work

[jazzynico (jazzynico)]

Marking it "in progress".
Don't hesitate to change the status when the patch is officially committed or released on UniConvertor.

[markus haider (markus.haider)]

Unfortuantly I came across a further issue. I created a colorplot using matplotlib, where the region inside the axes is rasterized (see issue2.svg). When I convert it to wmf (see issue2.wmf), this region vanishes. Another strange thing is, that the color of the colorbar labels gets changed.

[max (maxim-s-barabash)]

Unfortunately problems with the file issue2.svg, in the near future will not be resolved. The main reason is the filter wmfsaver.py, which has long been prepared but not integrated into the trunk. The man responsible for this operation is very busy.

[markus haider (markus.haider)]

Is it a difficult task? Perhaps I could try, if somebody gives me an idea of what has to be done where

Source code for wmf / emf is in the subproject pymfvu

If you have an interest please contact the project leader sK1 Forum

Thanks. From a fast look at the code I fear that I am not able to contribute something usable within a reasonable amount of time.
