configure the element.

body {
padding: 0;
margin: 0;
}
.view {
width: 100%;
height: 100vh;
box-sizing: border-box;

API
[triggerReset]
Resets the zooming/position for all elements on value change.
<lib-ngx-image-view [triggerReset]="updatingValue">
data-fit-to-parent
Limits the element to have minimal the container height
default: true
<img src="..." data-fit-to-parent="true">
data-limit-to-natural
Limits the max-size of the element to its natural size.
Usually useful for images
which should stop scaling at 1px = 1px
.default: true
<img src="..." data-limit-to-natural="true">
data-zoom-to-center
Stay centered if width
gets smaller than container width
.
If you want to have exact on-cursor-point zooming, even for images
smaller than the container, you need to disable this, but
consider the side-effect: The element might move aside while
zooming and width/height is still smaller than your box.default: true
<img src="..." data-zoom-to-center="true">
data-allow-zoom
Enable/disable zooming: default: true
When disabled, the element can not be zoomed.
<img src="..." data-allow-zoom="true">
data-allow-drag
Enable/disable dragging: default: true
When disabled, the element can not be dragged. But it still can
be zoomed. The zooming follows the mouse cursor.
<img src="..." data-allow-drag="true">
data-allow-drag-preview
Enable/disable dragging the preview: default: true
Preview means:
element.width === container.width
for landscape elementselement.height === container.height
for portrait elements
<img src="..." data-allow-drag-preview="false">
