I don’t think any thing similar to QPainter is available in QML. The purpose of qml as I see it is not to do low level painting, its more like building up on the existing simple qml items/components.

In order to manipulate the image, you need to use QPainter, qml can’t do image manipulation. You can create your interface in qml however and create a qml item that exposes the painting functionality by using signals and slots and properties.

thanks Vijay and sigrid , currently my solution is to implement a widget inheriting from QGraphicsProxyWidget , and export it to QML with qmlRegiesterType
