<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This looks fishy - and QTransform a tiny bit clumsy.
Does this work:
QVector shapeRects = shape.rects();
shape = QRegion(); // clear
foreach (QRect r, shapeRects) {
r.moveTo(r.x() * data.xScale() + data.xTranslation(),
r.y() * data.yScale() + data.yTranslation());
r.setWidth(r.width() * data.xScale());
r.setHeight(r.height() * data.yScale());
shape |= r;
}
the multiplications might need to be put into qRound or qCeil to avoid glitches.
This spares several qregion copies, conversions into and out of painter paths and the second shape translation.</pre>
