You can very easily scale a path, but it's usually wrong; scaling the view is the right thing to do in most cases.

To scale a path, simply call QMatrix::map(). So, something like:

QMatrix matrix;
matrix.scale(2, 1);
QPainterPath scaledPath = matrix.map(originalPath);

QMatrix matrix;
matrix.scale(2, 1);
QPainterPath scaledPath = matrix.map(originalPath);

To copy to clipboard, switch view to plain text mode 

In Qt 4.3, you can also use QTransform.
