`imageSize()` with svg images about drawbot HOT 6 CLOSED

Does image() support SVG to begin with?

from drawbot.

I was able to draw some svgs on a canvas, so I assumed drawbot supports them

Ah, it doesn't work on 10.15 for example. It's mostly an OS support thing.

That said the imageSize() implementation goes through some hoops to support PDF, (animated) GIF and "others". Maybe it needs some SVG handling code.

A lots goes wrong while drawing svg as images...

but we could get the size from the nsimage object, we just have to flag _hasPixels = True with the ext .svg here

from drawbot.

my workaround for now is this:

import xml.etree.ElementTree as ET
tree = ET.parse(imagePath)
_, _, imageWidth, imageHeight = [float(i) for i in tree.getroot().attrib["viewBox"].split()]

I understand that svg support as input format might be complicated and unreliable. I ended up converting the svg files in pdf with cairosvg and it worked fine. I'll open a pull request to add to the docs which formats are supported by the image proporties functions and the ImageObject.
