How do I render *parts* of a svg file?
- by Fake Code Monkey Rashid
Hello good people! :)
I want to render parts of a svg file by name but for the life of me I cannot figure out how to do so (using python + gtk).
Here's the svg file in question: http://david.bellot.free.fr/svg-cards/files/SVG-cards-2.0.1.tar.gz
On his site, David, says:
You can draw a card either by
rendering the file onto a pixmap and
clipping each card manually or by
using the card's name through a DOM
interface. All cards are embedded into
a SVG group.
I don't know what he means by a DOM interface. I have done some searching and the best result I found that seems to fit what I want to do is:
QSvgRenderer *renderer = new QSvgRenderer(QLatin1String("SvgCardDeck.svg"));
QGraphicsSvgItem *black = new QGraphicsSvgItem();
QGraphicsSvgItem *red = new QGraphicsSvgItem();
black->setSharedRenderer(renderer);
black->setElementId(QLatin1String("black_joker"));
red->setSharedRenderer(renderer);
red->setElementId(QLatin1String("red_joker"));
Notice however that it is for Qt and is not even written in python.
This is what I have so far:
#!/usr/bin/env python
from __future__ import absolute_import
import cairo
import gtk
import rsvg
from xml import xpath
from xml.dom import minidom
window = gtk.Window()
window.set_title("Foo")
window.set_size_request(256, 256)
window.set_property("resizable", False)
window.set_position(gtk.WIN_POS_CENTER)
window.connect("destroy", gtk.main_quit)
window.show()
document = minidom.parse("cards.svg")
element = xpath.Evaluate("//*[@id='1_club']", document)[0]
xml = element.toxml()
svg = rsvg.Handle()
svg.write(xml)
pixbuf = svg.get_pixbuf()
image = gtk.Image()
image.set_from_pixbuf(pixbuf)
image.show()
window.add(image)
gtk.main()
It doesn't work, of course.
What am I missing?
