Version: (using KDE KDE 3.4.1) Installed from: Compiled From Sources OS: FreeBSD http://www.livejournal.com/users/cniehaus/8585.html?thread=22409#t22409 I dont know much about QT but I was interested to learn about how KChart uses built in functionality of QPainter to export SVG. If it is feasible it would be really great if Kalzium could allow SVG export of things link the Periodic Table, or the Atom Models and allow people to incorporate them into their science reports and things like that. (Now to prove I read the TODO ask requested) http://websvn.kde.org/trunk/KDE/kdeedu/kalzium/TODO?rev=432227&view=markup The Kalzium TODO file suggests CSV and HTML export so I hope SVG can be added to that list. There is also a typo in TODO s/chemitry-nobel-prize/chemistry-nobel-prize/ Interoperability with and reuse of KChart components might be another way to benefit both programs rather than rolling your own custom graphing solution.
Good idea. Give us some time :)
No hurry, I'm glad you accepted the idea. I'm looking for ways to help promote SVG and OpenClipart.org because I believe it is important to not just use open standards but promote them to hold back proprietary standards. I am also interested in seeing Karbon 14 succeed and being able to work well with other KDE applications could help create more interest in it and in SVG. When I realised QT provided built in SVG support it seemed like a perfect opportunity to encourage various KDE applications to embrace SVG and I filed a few other requests and included the words [SVG Everywhere] in the summaries. I'm looking for other places to suggest SVG too if you have any good ideas. I should have pointed you directly to the kchart svg exporter: http://websvn.kde.org/trunk/koffice/filters/kchart/svg/ Thanks again and although I would love to see this added I dont want to rush you or distract you from the main purpose of Kalzuim with this tangent.
Now the following formats are supported: BMP EPS Jpeg2000 Jpeg Portable Bitmap Image Portable Pixmap Image Portable Graymap Image PCX PNG That is at least a good start I would say :)
That is an excellent start, particularly Encapsulated Postscript (EPS) support is good as that is what most Vector Graphics applications use for document interchange but being able to work directly with SVG would be even better. With Microsoft coming out with XAML/WVG soon I think it is more important than ever to promote standards like SVG, but like I said before no pressure, no hurry.
However, all those formats are not provided by kchart. They are provided by filter chains in the KOffice libs. Kchart itself only provides PNG and SVG.
Just a status-update: Ok, we finally depend on Qt 4.3. I am now trying to implement this using some new fancy stuff in it :-)
SVN commit 647745 by cniehaus: I added File->Save As... Now the table is "screenshot'ed" and saved in a file the user selects.

SVN commit 647807 by cniehaus: Ok, the SVG-renderer is in place. Currently, I am getting an assertion when I start a KFileDialog. That is why the name of the svg-file is still hardcoded. I will fix that as soon as my kdelibs is fixed.
