Hi Apryse Team,
we have complex PDF manuals with many layers in it, which makes the zooming in / out slow and unresponsive for a few secs afterwards. I’ve tried to check what makes our PDF slow in Webviewer and the only thing I found via Adobe is that it has really many layers for all the texts.
Is that something which can make zooming slow?
I’ve checked other PDF readers (i.e. PDF.js) and those are better here, as they seem to postpone rendering all until the zoom is completed. In Webviewer what I can see is the page gets rendered even mid-zooming which causes high spikes in CPU usage.
Could you help us how we could make zooming more performant on simply using the webviewer frontend?
