Possible bug in BorderImage



  • Creating a border pixel from a 3x3/4x4 pixel PNG where the center pixel/pixels is transparent gives a very strange result when put in a resizable "large" rectangle.

    The border only fills up the top part of the rectangle and there are severe performance decrease when resizing.
    Changing the border size to 2 instead of 1 fixes the problem though, however the border still looks a bit strange during resizing.

    Should borders be created by using rectangles with 1 pixel width or height instead?

    QML:

    @import QtQuick 2.1

    Rectangle {
    width: 300
    height: 200
    color: "green"

    BorderImage
    {
        anchors.fill: parent
    
        border { left: 1; top: 1; right: 1; bottom: 1 }
        verticalTileMode: BorderImage.Repeat
        horizontalTileMode: BorderImage.Repeat
        source: "borderImage.png"
    }
    

    }@

    Test environment:
    Windows 7/Windows 8, Qt 5.1 Angle, NVidia GeForce GTX 650
