I don't see a difference in your two pictures. Remember that QSvg only supports a subset of the complete svg features - see https://doc.qt.io/qt-5.11/svgrendering.html

Hi
Thank for upload.
Looking at
http://svgur.com/s/7XB
There is no build in margins.

what is see in svg viewer is just that svg page size is so big that it leaves no empty space around it
as its bigger than window can be.

if you scale the image slightly , it looks like

@kjnm
Its just due to it being very big default. ( the page size)

Try this one

Hi
Seem you just want to paint it using a border.
Not having a border inside image.
That you can easy do when painting it.

Like

void MiniSVG::paintEvent(QPaintEvent* ) {
  QPainter p(this);
  QSvgRenderer r; // this would normally be a member..
  r.load(QString(":/7XB_smaller.svg"));
  r.render(&p, rect().adjusted(64, 64, -64, -64));
}

sample to play with

if its only this image u need this for, you can also just change page size. ( view box)

that should work too.
