Hi,
I'm using PDFium plugin on single page view (ShowAllPages=False) to show say page ten of a PDF document. I'm trying to switch to ShowAllPages:=True and show the same page ten without it showing the first page.

If I'm already ShowAllPages=True, I can set the page shown using PdfViewer.PageIndex=9 and calculating the VisibleBitmapRect using PageHeight and PageSpacing. However, if I LockUpdate, ShowAllPages=True, set the page to ten, then UnlockUpdate it still shows Page One. Looks like I can only change after it is first rendered with ShowAllPages=True.

Is there a way I can jump straight to a page without showing Page One?

regards
Paul

Hi Paul

How about if you wrap ShowAllPages := True; and PageIndex := 9; in LockPaint/UnlockPaint?

Hi Paul

In the current beta it correctly displays the current page when enabling ShowAllPages. You can email me for it.
