OpacityMask only works on Images?

cscooper

I have the OpacityMask working fine when I apply it to an Image, but if I try to apply it to a Rectangle it has no effect (and no warnings or errors in the console). Is this a known limitation of the effect?

Thanks,
Chris

OpacityMask {

    source: bug

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
}

}
