Thanks. This was very helpful. I assume these z-values are the same as
Theme.pixelRatio?
For anyone interested, below is what I ended up doing, at least for now.
A Python script to generate PNGs from SVGs, e.g. position.svg to
posit...@1.00.png, posit...@1.25.png, etc. and a JavaScript function for
use in QML to load the closest match. My current need was just icons on
a map, meaning I don't have to match Sailfish's standard sizes, I just
wanted the icons to scale relative to the pixel ratio. Tested on Jolla 1
and tablet, seemed to work as expected.
#!/usr/bin/env python3
import glob, os, xml.dom.minidom
for svg in glob.glob("*.svg"):
doc = xml.dom.minidom.parse(svg)
doc = doc.getElementsByTagName("svg")[0]
width = int(doc.getAttribute("width"))
height = int(doc.getAttribute("height"))
assert width > 0 and height > 0
for ratio in [1.00, 1.25, 1.50, 1.75, 2.00]:
png = "{}@{:.2f}.png".format(svg[:-4], ratio)
os.system("inkscape -f {} -e {} -C -w {:.0f} -h {:.0f}"
.format(svg, png, ratio*width, ratio*height))
function getIcon(name) {
var ratios = [1.00, 1.25, 1.50, 1.75, 2.00];
var minIndex = -1, minDiff = 1000;
for (var i = 0; i < ratios.length; i++) {
var diff = Math.abs(Theme.pixelRatio - ratios[i]);
minIndex = diff < minDiff ? i : minIndex;
minDiff = Math.min(minDiff, diff);
}
var ratio = ratios[minIndex].toFixed(2);
return "icons/%1@%2.png".arg(name).arg(ratio);
}
