将图像拆分为单元格QML / QT

Question

I was wondering if there was a way to split image into cells (ie 4*4 grid) in QML or C++? So say I load an image in a window/rectangle and want to split it in a grid, to be later able to manipulate each cell separately. Thanks in advance.

Also you can load an image into Image item with offset. Since once loaded image is cached there will be no additional overhead.

Window {
    visible: true
    width: 600
    height: 600

    Component {
        id: imgComponent
        Item {
            property int row: index / 3
            property int col: index % 3
            x: col * (200)
            y: row * (200)
            width: 200
            height: 200
            clip: true
            Image {
                x: col * (-200)
                y: row * (-200)
                width: 600
                height: 600
                fillMode: Image.Pad

                Component.onCompleted: console.log(row, col);
            }
            MouseArea {
                anchors.fill: parent
                drag.target: parent
            }
        }
    }

    Repeater {
        model: 9
        delegate: imgComponent
    }
}
