Hello,

using ZoomStart and ZoomEnd, sometimes the windows becomes blank. The problem occurs when ZoomEnd function is called. I tried not to use ZoomStart and ZoomEnd and use SetRatio instead, but then view becomes blury.

I am using an example in your original package called PDFViewer.java . Maybe after SetRatio I have to do something more, re render or set view size? Please let me know, thanks!

p.S. This post should be in Android Development section, don't know how to choose it.

Yes I know that, but how to solve that? Sometimes it shows blank page and and then renders normally, but sometimes it just get blank and then you have tap once to go back to the original view. So even it is timer based sometimes it stucks and don't render it after zoom. Thanks for your replies!
