Simple demo page to show viewer behavior during resizing of the container.

The viewers' container elements are styled with width and height of 100%,

|
with dimensions set by CSS properties on a parent element.

<h3>Demo: Issues with styling the viewer element when an image is opened</h3>
|
|
<p>If a DOM/CSS operation is triggered by a viewer event (e.g. the 'page') event
|
|
for multi-page images, the timing of the viewer resizing itself (if autoResize=true)
|
|
can be inconsistent - sometimes before, sometimes after the image has finished loading
|
|
and the Viewport.goHome() call is generated. To ensure consistency, call viewer.forceResize()
|
|
after altering the page layout.
|
|
</p>
|
|
<p>Note: to see this in action most clearly, select the options for "preserveImageSizeOnResize: false"
|
|
and "Use polling" above.
|
|
