GaussianBlur in a specific Area

Leon_2001

Hi everyone,

I have a smaller Rectangle in an Image and I want this area to be blurred.
Unfortunately, I take the complete Image as the source and not just the part where the Rectangle is.

How can I achieve, that only the area where the rectangle is is blurred?

import QtQuick.Controls 2.3
import QtQuick 2.10
import QtGraphicalEffects 1.0

ApplicationWindow {
  width: 700; height: 500
  visible: true

  Image {
    id: image

    anchors.fill: parent
    source: "Sierra.jpg"
  }

  Rectangle {
    id: rect
    width: 200; height: 200
    anchors.centerIn: parent
  }

  GaussianBlur {
       anchors.fill: rect
       source: image
       radius: 8
       samples: 16
   }
}

You should be able to use MaskedBlur http://doc.qt.io/qt-5/qml-qtgraphicaleffects-maskedblur.html
