Maximum size of QQuickPaintedItem



  • Hello there.
    What is the maximum size (width/height) for QQuickPaintedItem? 10000 is ok, but if I set more only black screen draws. The problem is I need to draw on really BIG surface (>100 000 000 px) and I can't use OpenGL (no GPU), so only QPainter left.



  • Maybe it is not the direct answer for Your question, but did you consider to paint on "virtual" QGraphicsScene and render just desired part of that "virtual" composition to QPainter?
    I.e. QCharts module for QML works that way.
