Convert SVG->PDF with transparency
Greetings.
I just created a poster using Inkscape and want to make a PDF version to distribute. I use a lot of transparency in the poster, but unfortunately Inkscape's export filters for Postscript and PDF don't preserve the transparency.
Can someone suggest another SVG to PDF converter which will preserve transparency? I tried Cairo's svg2pdf, but it just segfaults midway through processing the file.
BTW, I'm running GNU/Linux. I do have access to a Windows XP machine, but not to hundreds of dollars to buy expensive Adobe software.
Regards, Tristan

Transparency is a feature of PDF1.4 which isn't all that well-supported. It's unfortunate, because with transparency you can do many simple beautiful effects in SVG.
I have had a degree of success with batik, from the Apache project. It is mostly billed as a "SVC rasterizer" but it can also "transcode" SVG to PDF. Sometimes it eats my fonts, sometimes it eats my arrow-heads, but 98% of the time it does exactly what I want.

The software itself is Free, but it depends on non-free components of the sun JVM, and doesn't currently work with gcj. Hopefully that will change soon.

Cairo's svg2pdf was just a demo and is probably abandoned. Check out the rsvg-convert utility from librsvg. I don't know if the utility is included in the usual distribution packages, so you may have to grab CVS and build from source. rsvg-convert does currently rasterize the SVG into PDF but it is still something to look at.

Alas, batik too fails miserably:

flowRoot (i.e. Flowed Text) is an SVG 1.2 proposed object type. Batik is an SVG 1.1 renderer.
Change the flowRoot objects to regular text (Text->Convert to Text) and try Batik again.

Doing so let Batik run without producing any errors, but the PDF it produced isn't quite right. Adobe Reader refuses to open it, saying "An unrecognized token '-3.662109375E-4' was found.". Kpdf opens it, and while there is indeed transparency in the right parts of the image, in other parts there is transparency where there shouldn't be any!

Inkscape conversion from SVG to PDF is using PS. PS as I know it doesn't support transparency, and thats the main problem.
When I need to export an SVG to PDF with transparencies I need to flatten the colors. I can't remember well how I do that, but basically use the pick color tool to check the real visible color, and change the object color/transparency accordingly.
I hope this helps. Hugs Alberto

Two things I didn't see people mention:
- Scribus has good SVG import and good PDF export.
- I've used PDF creator on Windows before, and I thought that I got transparency there. I don't remember for sure (it was a long time ago) but you might try that.
