[SOLVED]Qt Quick and QML Image Zoom

[Wroman]

Hi there !

I've got a problem on moving on my image when i zoom on it.

Basically, i scale the image to reproduce a zoom.

What i'm doing now is translating the image.

@ property int transformX:0;
property int transformY:0;

Rectangle
{
id:borderEmulation;
color: "lightgray";
clip: true

        anchors
        {
            fill: parent;
            margins: 2;
        }
        Image
        {
            id: visibleImg;
            source: "qrc:/visible";
            antialiasing: true;
            fillMode: Image.PreserveAspectFit;
            //transformOrigin: Item.Center;
            transform: Translate { y: transformY*visibleImg.scale; x: transformX*visibleImg.scale }
            anchors
            {
                fill:parent;
                bottomMargin: myProgressBar.height+10;
                margins: 2;
            }
        }

}@

And 4 button that increase / deacrease by 20 the transform(X/Y).

My point is : is here a way to know when i'm zooming out of my picture ?

ie. when i have to stop my translation because the right/left/top/bottom end of the image is displayed ?

Regards

Solved by :

@
MouseArea
{
anchors.fill: parent;
onClicked:
{
if(transformY > -((visibleImg.height/2 - (visibleImg.height-visibleImg.paintedHeight)/2)(visibleImg.scale-1)) + visibleImg.scale10)
transformY -= visibleImg.scale10;
else
transformY = -(visibleImg.height/2 - (visibleImg.height-visibleImg.paintedHeight)/2)(visibleImg.scale-1);
}
}

Resp. with +/- and X/Y on the appropriate directions.
