SVG images

SVG images

[Ville Voipio]

I would need to embed some SVG images into a ConTeXt document. I have 
done some research on the topic, and the seemingly trivial task seems 
all but impossible.

I found a few solutions, but none of them fits my needs:

- I want to have my vector images in vector format (i.e., no 
Inkscape-to-PNG)

- alpha-channel transparency is used in the images, and it should be 
present in the PDF file, as well (i.e., no Inkscape-to-EPS)

- if I used commercial products, I would not use SVG (i.e., the 
converter should be open source)


The images have been (will be) created with Inkscape. While being 
otherwise a surprisingly nice piece of software, Inkscape does not seem 
to export PDF for some reason or another (licencing, time, etc.).

I have the impression I just ran out of luck. Did I?

Skencil http://www.skencil.org can open and save SVG and exports to PDF via 
reportlab. As I have not worked with transparency yet I do not know if that 
works all the way from SVG to PDF. Could you post me a little sample image to 
run it through Skencil?

Yours sincerely

Cairo (www.cairographics.org) plus a librsvg development version
(librsvg.sourceforge.net) seem be able to produce pdf from svg but i
haven't tried it yet. You also need a bit of code.

All right. I sent some files to Tobias (above), and he very kindly made 
some experiments. Skencil could not do this (alas!) but Scribus did it 
almost correctly. Scribus seems to have some problem with alpha channel 
gradients, but the problem looks like a problem with some color 
correction/conversion, not a real SVG/PDF issue.

I will go on experimenting and report here if I find out something more.

so, you can let context do runtime conversions and it will only convert when the graphic is updated 

probably one of those manuals that nobody noticed -)

Hello Ville,
for the first test of which I sent you the result I used the current stable 
version 1.2.4.1 of Scribus. The developer release 1.3.2 of Scribus is a bit 
more verbose upon opening of your test.svg and says that this SVG contains 
features not yet fully supported in Scribus - I guess it is these alpha 
channel gradients?
But I just read that there is a native ConTeXt solution.

Yours sincerely
