Converting SVG -> PNG with transparent backgrounds

Tuesday, July 29th, 2008

I’ve tried to convert an SVG image with transparent background to a PNG using the Image Magick’s convert command line tool. The result was an image with a white filled background.

After struggling with Yahoo search for about half an hour, I came across to this simple and useful tip:

convert -background none folder.svg folder.png

That’s it! No more white background ;)


PyQt4 Tutorial

Thursday, June 26th, 2008

PyQt4 is the wrapper for Trolltech’s Qt4 libraries. On the riverbank site you can find the sources and the windows binary; ubuntu seems to ship the binary on the official release, simply look for pyqt in synaptic.

Here is a good PyQt4 tutorial: zetcode

And here another good in Italian: un tutorial facile facile

Anybody knows about the binary on mac? I’ve found something on finkproject: anybody tested it?
