I downloaded the images & used the QML code from the OpacityMask documentation page (qt-project.org/doc/qt-5/qml-qtgraphicaleffects-opacitymask.html) but it isn’t doing what I expect. I though I would end up with a mostly red screen with a butterfly-shaped picture of a bug, but what I get instead is a boring square picture of a bug (on a red screen). There are no warnings in the console that would indicate the problem. Am I just mis-understanding the purpose of OpacityMask?
Thanks,
Chris
