OpacityMask only works on Images?

Hi, It does work. You are putting in wrong source and maskSource. Try this import QtQuick 2.0 import QtGraphicalEffects 1.0   Item {     width: 300     height: 300       Rectangle     {         id: bug         width: parent.width         height: parent.height         color: "blue"         radius: width/2     }       Image {         id: mask         source: "http://qt.digia.com/Global/About Us/Qt_master_logo_CMYK_300dpi.png"         sourceSize: Qt.size(parent.width, parent.height)         visible:false         width: parent.width         height: parent.height     }       OpacityMask {         anchors.fill: mask         source: mask         maskSource: bug     } }
