refresh page when annotation added works partially

Hi,
When translating an existant annotation from a certain coordinates to another one in RDPDFReader the content of the page disappears for like half a second and that is not the case with PDFReader

We couldn't reproduce this issue with RDPDFReader, can you please check with the latest version

If you still face the issue, can you send us a sample file?

I think it's related to the size of th PDF I'm using a PDF file of 360 pages and deplacing a bitmap annotation. and I've got this problem too when barring text (I don't if I should start a new topic for this sorry). The first one what the sample provides and for the second what should be.(made by another pdf editor)

We tested the library with document whose size was 2Gb or 10.000 pages.
I think the issue could be related to some data structure in the document itself.
May you provide your document so we will do some deeper analysis?

I'm am sorry for the long time taken to answer. Below is a sample where it's clear when adding or moving an annotation makes the page blink
I guess the atachement is too large to be uploaded, this is the pdf link : pdf

Hi,
we have checked your pdf with PDFReader and RDPDFReader and we’ve got the same result, it’s related to the pdf structure itself not the layout used.

Using PDFLayout will introduce better rendering performance with this kind of documents especially while zooming.
But during annotation movement it’s normal to face this kind of behavior.
