Panzoom Library And Filling A Div With A Centered Image

Post a Comment
The Panzoom library (https://timmywil.com/panzoom/demo/) allows you to move and zoom an image in a div: Everything is working properly. Now I would like these images to fill their

Solution 1:

I'm not sure, but I think this is ok:

var zoomWraper1 = document.querySelector(".zoom-wrapper1");
var zoomWraper2 = document.querySelector(".zoom-wrapper2");

var panzoom1 = Panzoom(document.querySelector(".zoom-area1"), {
  maxScale: 6
});
zoomWraper1.addEventListener("wheel", panzoom1.zoomWithWheel);

var panzoom2 = Panzoom(document.querySelector(".zoom-area2"), {
  maxScale: 6
});
zoomWraper2.addEventListener("wheel", panzoom2.zoomWithWheel);

panzoom1.pan(0, 0);
panzoom1.zoom(300 / document.querySelector(".zoom-area1 img").height);

panzoom2.pan(0, 0);
panzoom2.zoom(300 / document.querySelector(".zoom-area2 img").width);
body {
    width: 100%;
    height: 100vh;
}

button {
  margin-right: 20px;
}

.main-container {
    display: flex;
    align-items: center;
    justify-content: center;
    height: 100%;
}

.zoom-wrapper1 {
    width: 300px;
    height: 300px;
    border: 5px solid #1c6ea4;
  display: flex;
    align-items: center;
    justify-content: center;
}

.zoom-wrapper2 {
    width: 300px;
    height: 300px;
    border: 5px solid #1c6ea4;
  display: flex;
    align-items: center;
    justify-content: center;
}

Definitely the problem is that the zoom escapes to the sides, it is not directed to the point pointed by the mouse. This needs improvement.
