Converting SVG files to different file formats
Hi
I have a Java (JDK 1.4.1) standalone application which generates SVG files
(Charts with JFreeChart). This charts should be converted into different
file formats like JPG, PDF and maybe EPS. The converted files must be high
quality files for printing media. I try to do that on different ways, f.e.
with Batik, FOP and Image Magick, but the results are bad. I use Windows
2000 as OS.
- How can I do that?
- Does anybody know a good way to convert files form SVG into different
formats with a high quality?
- Has anybody sample code how to improve the quality when I use Image Magick
or Batik?
- Has anybody sample code how I can convert an SVG file into high quality
PDF using FOP?
- Is there an another good tool or Java library to do that?
Thanks a lot
Regards

FOP uses Batik for rendering SVG, and there isn't much FOP
can do for quality besides
http://xml.apache.org/fop/faq.html#faq-N1036C
(well, the PDF transcoder is part of FOP, but because PDF is
vector graphics too, I can only imagine very small roundoff
problems (1/1000 pt) and blantant bugs influencing quality).
How do you define "high quality", and why do you thing you
aren't getting enough quality now?
BTW: Please don't crosspost.

FAQ. See
http://xml.apache.org/fop/faq.html#faq-N1036C

Waht do you mean with "code example"?
There are examples in the FOP distribution, under docs/examples/fo/svg.
You can refer to an SVG file in a fo:external-graphic, or you can embed
a SVG within the FO document using fo:instream-foreign-object. See also
http://xml.apache.org/fop/svg.html
Perhaps also
http://marc.theaimsgroup.com/?l=fop-dev&m=103047736819724&w=2
just for the fun of it.

Bad quality means that the text (fonts) is bad looking (rasterd, gray not
black, ...). It seems to be the resolution or something like that.

Do you have a code example how I can convert SVG to PDF using Batik/FOP?
Thanks

Under Linux, you can get high quality images from SVG files using the
convert utility:
convert -size new_widthxnew_height! file.svg file.jpg
(jpg can replaced by whatever file format you want)
Unfortunatly I have never managed to make this command work under
Windows2000 : the generated image keeps its original size !
Is it a bug ? If not, does anyone can help us ?

I guess we need to understand what 'results are bad' means, please
elaborate, what specifically is bad about them?
The latest versions of FOP should do a good job of PDF generation.

Since you are in a Windows environment, I would take a look at Adobe
Illustrator. Whether this can be used in a batch-oriented environment, I
don't know, but I think most of the Adobe products now have some of their
API exposed in scripting of one sort or another. If you don't need
on-the-fly batch work done, it would definitely be a good choice (but not
open source).
