Hi Guys,

Any idea on how to import SVG files and use them as images in classic wxPython?

Thanks,

Emad

Hi Steve,

I have tried cairosvg and many other versions of cairo extensions but none of them gave me desirable results. Most of the time the quality of the image isn’t good. But I just now found that PyQt4 can be used to convert svg to png. It gives excellent quality images.

from PyQt4.QtSvg import *

from PyQt4.QtGui import *

def convertSvgToPng(svgFilepath,pngFilepath,width):

r=QSvgRenderer(svgFilepath)

height=r.defaultSize().height()*width/r.defaultSize().width()

i=QImage(width,height,QImage.Format_ARGB32)

p=QPainter(i)

convertSvgToPng(‘Draft_Finish.svg’,‘Draft_Finish.png’,200)

Thanks,

Emad

I noticed I didn’t copy the complete function

def convertSvgToPng(svgFilepath,pngFilepath,width):

r=QSvgRenderer(svgFilepath)

height=r.defaultSize().height()*width/r.defaultSize().width()

i=QImage(width,height,QImage.Format_ARGB32)

p=QPainter(i)

r.render(p)

i.save(pngFilepath)

p.end()

convertSvgToPng(‘Draft_Finish.svg’,‘Draft_Finish.png’,200)

If you can use an external tool to convert, then I"d take a look at InkScape – it’s a GUI vector graphics program, but it can be called on the command line to render SVG – and does a very nice job of it.
