I'm trying to use some royalty-free cliparts. Now, although they clearly are vector (paths can be manipulated with the Edit paths nodes, textures are recognized as gradients...), they get rasterized when converted to EPS (either when saved to EPS or using the command line).
For instance:

SVG Images Rasterized When Converted to EPS
Re: SVG Images Rasterized When Converted to EPS
Hi.
Most probably because saving transparency in eps is not supported, which the glass jar has.

Re: SVG Images Rasterized When Converted to EPS
Looks like you're right! I brought the opacity of the main surface to 100% (it was 44%), and the EPS export is now full vector (although Acrobat Distiller won't convert the resulting EPS file to PDF, but that's another story! 
)
For me own education, is it the EPS format or the conversion filter that does not support transparency?
Many thanks!

THE FUTURE OF PRINTING LIVE TRANSPARENCY: POSTSCRIPT 3
PostScript 3 printers that support Adobe PDF 1.4 (Acrobat 5) files will accept and process the “live” transparency that can be saved in
PDF 1.4 files. This capability is built into the new PostScript Language version 3015, which was released to Adobe OEM partners in spring
2000.

Theoretically it is available, just as gradients.

As far as I know, inkscape uses ghostscript when dealing with eps files, so maybe check that too.

Sorry but I cannot get a straight quote from the related postscript specification.

The limitation is in the file format. The conversion filter “supports” it by rasterization (to preserve the appearance).mrgou wrote:For me own education, is it the EPS format or the conversion filter that does not support transparency?
Inkscape uses Ghostscript only for Import of PostScript-based file formats (PS, EPS).Lazur URH wrote:As far as I know, inkscape uses ghostscript when dealing with eps files, so maybe check that too.
Export to PostScript-based formats (PS/EPS) is handled internally, based on the cairo graphics library and has nothing to do with Ghostscript.
Re: SVG Images Rasterized When Converted to EPS
Hmm I do remember being corrected for that ghostscript part, should have known.
But I also remember that I used to say eps is not capable of transparency at all, and then been told that technically it is possible.
Though couldn't find those topics with searching.
