Event listener for currentPageNumber fully rendered

[David Shorthouse]

Folks,

Is there a property or method in your PDFView that would allow me to determine when the text layer content for the current page is fully rendered and appended to the DOM?

I tried to use PDFView.pages[window.currentPageNumber-1].renderingState === 3 but no such luck. I had assumed renderingState meant ALL the text has rendered and is currently in the DOM.

What I am attempting to do (as I see others here as well) is manipulate the text, but to do so, the text layer content must be fully present. I've made several attempts with some degree of success, but because I must be doing my injections as the text layer gets rendered (i.e. hasn't yet fully appended), the sizes and positions of the div elements get mangled.

Thanks for any insight.

Dave

There isn't currently an event for when the text overlay is finished rendering. The rendering states you're looking at only apply to the canvas rendering. However, you could add an event at https://github.com/mozilla/pdf.js/blob/master/web/viewer.js#L1753 to be notified when the text layer is done though.

Does manipulating the text overlay actually affect the displayed text?

No, the text overlay is invisible and is just used for text selection.

Hi Dave,

I think you'll have to continue looking on how to effectively do text
manipulation as Brendan said below, manipulating text layer doesn't change
what's displayed.

I am trying to do something similar, so if you have any ideas, would love
to hear.

Thanks, Sunil
