Re: [Goocanvas-devel] loading and displaying svg files into goocanvas

[<mys...@fr...>]

Hi,
Finally, I'll work with bitmaps and update them when necessary when zooming.
I thought that svg drawing could be done easily and wanted to benefit from the
fact of having no pixelisation when zooming.
David Madeley, who once developped a Mahjong game proposed me to redraw the
bitmaps to bigger/smaller resolutions if needed. So I think this is what I'll do
for I do not have the ability right to do subclassing.
It's still nice though to hear that only two methods have to be overriden if
every I had chosen to write a new class.

Thank you again for your help,
Jonathan
