File types
We need EPS, Adobe SVG, and PDF in/out support. We really need to import/export the following formats:
- EPS
- Adobe SVG (must be interoperable!)
- Postscript
- Adobe Illustrator File Formats (Newer ones are PDF 1.4 documents)
To really be considered a successful application, we must take these file formats in and be able to save them out.
Other useful formats might be:
- Enhanced Windows Metafile (emf)
- Windows Metafile (wmf) (there are a lot of clipart packages in this format)
- Computer Graphics Metafile (cgm)
- HP-GL2 (plt)
- Embroidery file formats (Ksm, Melco, PCS, PES, Tajima,...) ???
- CorelDRAW files (cdr). Their UI is quite similar to Inkscape's (owing to inspiration of both by Xara's ancient Artworks for the Acorn Archimedes); it suggests a path of least resistance for those seeking to convert.
- The newer Macromedia Freehand formats: .fh9, .fh10, and .fh11 (by file extension in Windows). At least the ability to read basic vectors, fill color, and stroke width (while possibly ignoring page layout for compatibility). Versions older than Freehand 8 might also be useful to revive those ancient drawings one made using the original Apple Macintoshes (prior to His Steveness' firing and subsequent rehiring).

Existing Conversion Tools
Scripts and other applications that provide conversions, and might be useful to investigate as solutions to this dilemma.

- Scribus EPS to SVG (at least)
OpenOffice OODraw-to-SVG
OpenOffice can export and import SVG, but they do not always work.
For the SVG import in Open Office, do not use the import-from-file function. Instead, open the SVG, and copy it to your document.
Possibly a filter could be created for Inkscape from their code, to enable at least being able to load OODraw's SXD file format into Inkscape.
Browsing through OO's sourcecode, this appears to be the parts that do the SVG writing:
OpenOffice/filter/source/svg
SOTranscoder.java svgfilter.cxx svgimport.cxx svgwriter.hxx exports.map svgfilter.hxx svgscript.hxx makefile.mk svgfontexport.cxx svguno.cxx svgexport.cxx svgfontexport.hxx svgwriter.cxx
You can download the OpenOffice sourcecode from one of the OpenOffice mirrors. E.g.:
http://www.mirror.ac.uk/downloads/sunsite.dk/openoffice/contrib/rc/1.1.4rc/OOo_1.1.4rc_source.tar.gz
There is a webpage with some info about a new SVG exporter, here:
http://graphics.openoffice.org/svg/svg.htm
This includes a java sample test, that could perhaps be used as a starting point for a filter...
http://graphics.openoffice.org/svg/SVGExportTest.java
Perhaps that could be recast into C++ so that a compiled filter could be made of it.
The page also includes a binary svgexport.so package. Perhaps if this is fairly stand-alone, a filter program could be written in C++ based on the above java testcode that links against svgexport.so and provides its functionality on the commandline as a sxd2svg tool.
nm reports that it provides the following functions:
00005f9c T component_getFactory 00005d28 T component_getImplementationEnvironment 00005d44 T component_writeInfo
ldd reports that this .so has the following dependency requirements:

Other Conversion Tools
When doing prepress work, its better to convert from ps to pdf on the commandline. there are several options available that make the result better fit the job, this is an example ps2pdf command:
ps2pdf12 -dProcessColorModel=/DeviceCMYK -dPDFSETTINGS=/prepress -dUseFlateCompression=true -dColorConversionStrategy=/UseDeviceDependentColor -dDownsampleColorImages=false -dDownsampleGrayImages=false -dDownsampleMonoImages=false -dAutoFilterColorImages=false -dAutoFilterGrayImages=false -dColorImageFilter=/FlateEncode -dGrayImageFilter=/FlateEncode -dMonoImageFilter=/FlateEncode input.ps output.pdf
PSStill example: convert a grayscale 25x70 cm inkscape exported postscript file to pdf:
pstill -i -2 -c -c -c -c -t -B -w 708,66 -h 1984,25 -o output.pdf input.ps
