Hot to get the Zoom Mangification string

[DSSavant]

Real simple, I need something that tells me that the current page zoom level is "FitWidth" or "FitPage" or ...

The following will only give me the numeric zoom level:

DoVerb("Documents[#4095].Pages.Zoom", "get", null, myOut, 0); Returns 54 when it is FitWidth.
DoVerb("Documents[#4095].Pages.Zoom", "get", null, myOut, PXCVA_Flags.PXCVA_GetNamed); Returns 54 when it is FitWidth.

So what am I missing here?

Hi, DSSavant.

You may use:

Code: Select all

DoVerb("Documents[#4095].Pages.Zoom", "getNamed", null, myOut, 0);

or:

Code: Select all

GetProperty("Documents[#4095].Pages.Zoom", myOut, PXCVA_Flags.PXCVA_GetNamed);

The code:
DoVerb("Documents[#4095].Pages.Zoom", "get", null, myOut, PXCVA_Flags.PXCVA_GetNamed);
- does not work in your case because "get" operation have greater priority and PXCVA_GetNamed flag is ignored.

Neither of the commands you suggest will return back "FitWidth" after the viewer has been told to specifically "FitWidth".

When executing the DoVerb to set the zoom level:

Viewer.DoVerb("Documents[#4095].Pages.Zoom", "set", (object)"FitWidth", out myout, 0);

myout will equal "FitWidth" simply because that is what was passed in. If you then call the following:

Viewer.DoVerb("Documents[#4095].Pages.Zoom", "getNamed", null, out myout, 0);

say after an event notification that the zoom level has changed, myout will equal the numeric value of "FitWidth" for the specific page. In my case it will equal "51%". I need a command that gives me the enumeration value for FitWidth or the string "FitWidth". If I view another page and it is landscape, then my view % will not be the same and therefore I will not be able to tell if 51% is truly "FitWidth".

I need this so that I can keep my menu's and toolbar buttons in sync with the viewer at all times. Put another way, I want my menus and toolbar buttons to be set based upon events being fired from the viewer. This way, I will always know they are set correctly. Compare this with setting them during the button or menu click events.

Hi, DSSavant.

Sorry but I was mistaken some in my previous post.
For obtain actual zoom level you should call:

Code: Select all

DoVerb("Documents[#4095].Pages.Zoom", "get", null, myOut, 0);

after this myOut will contain floated number which represents number of percents, or with "getNamed" - text like as "120%".
For obtain actual zoom mode:

Code: Select all

DoVerb("Documents[#4095].Pages.ZoomMode", "get", null, myOut, 0);

after this myOut will contain int. number(or string with "getNamed") which represents:
0 - "Percent"
1 - "ActualSize"
2 - "FitWidth"
3 - "FitPage"
The "ZoomMode" is read only property. Will be described in the next build.
Remark: you may use the "Zoom" property for setup any zoom level or any predefined zoom mode(as described in the Help already):

Code: Select all

DoVerb("Documents[#4095].Pages.Zoom", "set", "FitWidth", null, 0);

HTH.
