Qml as a vector source for printing.
-
Hi All,
I'm just wondering whether it's possible to either render a declarative item at a higher resolution, or even as vector elements.
I've tried for example using a QPrinter to print a QDecalarativeView's scene, however while elements manually added to the scene such as text are rendered as vector art, declarative items are rasterized at screen resolution.
Any ideas?

"Here":http://developer.qt.nokia.com/forums/viewthread/1181/ is kind of similar topic.

Thanks sergeev, but that's unfortunately unrelated.
I've been digging in the various qml element implementations and they're mostly using QPainter primitives, so it should be possible - but I'm guessing something in qml's declarative item hierarchy is perhaps caching to a bitmap thanks to optimizations.

Hi,
Ultimately almost all of the painting in the QML graphical elements is cached into pixmaps for performance reasons. This is done in the elements themselves (have a look at QDeclarativeRectangle::generateBorderedRect(), for example), so I can't think of an easy way to get around this without hacking all of the elements, or writing your own set of vector-based elements.
Regards,
Michael
