svg file gets wrong size

[qtbeginner0]

Hi,

can someone tell if there is a workaround for this svg bug?

The problem is when exporting to svg the width and height properties/attributes are wrong.

...
<svg width="wrong value" height="wrong value"
...

...
<svg width="wrong value" height="wrong value"
...

what are you exporting? and to what you are exporting?

I'm drawing things using QSvgGenerator as the paint device for QPainter.
And drawing things, using something like QPainter::drawPolyline... .
(saving the drawing as .svg file)

Define "wrong". What are you expecting to see? Why are you expecting that? What are you actually seeing?

Actually it's the same behaviour as explained in the link in my first post.
So let's say this is my code:

QSvgGenerator generator;
generator.setFileName(file);
generator.setSize(QSize(200, 200));
generator.setViewBox(QRect(0, 0, 200, 200));
generator.setResolution(25.4);//setting the resolution
 
QPainter painter;
 
painter.begin(&generator);
painter.drawRect(10,10,100,100);
painter.end();

QSvgGenerator generator;
generator.setFileName(file);
generator.setSize(QSize(200, 200));
generator.setViewBox(QRect(0, 0, 200, 200));
generator.setResolution(25.4);//setting the resolution

QPainter painter;

painter.begin(&generator);
painter.drawRect(10,10,100,100);
painter.end();

What I get is:
#without setting resolution I get (first lines of the svg file):

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg width="70.5556mm" height="70.5556mm"
 viewBox="0 0 200 200"

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg width="70.5556mm" height="70.5556mm"
 viewBox="0 0 200 200"

#when setting resolution to 25.4 I get (first lines of the svg file):

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg width="203.2mm" height="203.2mm"
 viewBox="0 0 200 200"

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg width="203.2mm" height="203.2mm"
 viewBox="0 0 200 200"

what I would like to get:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg width="200mm" height="200mm"
 viewBox="0 0 200 200"

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg width="200mm" height="200mm"
 viewBox="0 0 200 200"

As I define the size as 200,200 I would also like to get a 200mm,200mm drawing (so my rectangle has the correct size of 100mm,100mm).
