Hey, thanks for the lib!

It works very good so far, but the getPageBitmap is returning a non initialized bitmap.
Is there a way to get around this?

thanks

Hi DonManfred

I'm still using your old library, and wished I could switch easily, but I can't - there are some questions ..

I have these procedures ..

Sub PDFView_onLayerDrawn(cv As Object, pageWidth As Float, pageHeight As Float, Page As Int)
....
End Sub

Sub PDFView_onLoadComplete(Pages As Int)
...
End Sub

Sub PDFView_onPageChanged(page As Int, pageCount As Int)
...
end sub

Now - how can I get these events with your updated different library ? Any advice ?

Thanks
Marco

Hi DonManfred. The lib seems to work ok a couple of times, but when I view a PDF for the third time, it crashes with the message below, any ideas?

Fatal signal 11 (SIGSEGV), code 1, fault addr 0x14 in tid 20350 (FinalizerDaemon)

Thanks a bunch for this library. I just have one issue: whenever I double tap to zoom in the viewer gets very glitchy.
Any idea what might cause that? If you've got a sec could you perhaps make a version of the library without it? I thought about catching the press event but that would also disable the movement wouldn't it?
Thanks in advance.
