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
