Continuous zooming

[relapse]

Hi, a new question: I need a function to zoom in/out a document without defined zoom values (like the function "Zoom100"). In the docs I've found the function "ZoomTo". If I use it in this way (C#):

object data;
ctrl.DoVerb(null, "ExecuteCommand", "ZoomTo", out data);

-> what does the function call look like if I'd like to zoom a document to e.g. 22%?


Thanks.

what does the function call look like if I'd like to zoom a document to e.g. 22%?

Not C#, but an easy VB example:

Code: Select all

pdfZoomFaktor = 22
DoVerb "Documents[0].Pages.Zoom", "set", pdfZoomFaktor, Nothing, 0

Thanks a lot. It works!

I'm facing the same problem but I think this question is still unanswered - although the workaround works for me, the essence of the problem is how to pass data to executeCommand operation, i.e. ZoomTo.. (?)

Hi 1shadow,

I've asked one of the Viewer SDK experts to assist here and we will post a bit later here our further comments.

Hi, 1shadow.

The 'ZoomTo' is simple UI-command, it works like button in toolbar or item in drop-down menu. So you cannot pass additional arguments to it.

The changing zoom by (thanks to Dorwol):

Code: Select all

pdfZoomFaktor = 22
DoVerb("Documents[0].Pages.Zoom", "set", pdfZoomFaktor, null, 0)

or by:

Code: Select all

pdfZoomFaktor = 22
SetDocumentPropperty(docID, "Pages.Zoom", pdfZoomFaktor, 0)

- is the right way, optimal for developers.

Best
Regards.
