zoom in, zoom out in Book

[Kamal Mostofi]

Hi,
I would like to zoom in/zoom out on pages within my book. Is it possible? if it's possible, do you have an example? Can you share it with me please?

Many thanks in advance.

Hi Kamal Mostofi,

Currently RadBook  does not provide such build in functionality.
However you can add your custom logic in order to implement the desired zoom in/ zoom out behavior.
The following article can be helpful:

Dear Telerik,

Hello Ridi,

 RadBook and RadRichTextPageView (which is used in the templates of RadBook) do not implement a scaling mechanism.
However, you can use the built-in ScaleTransform and set different scaling values. This can be done like this:

this.book.RenderTransform = new ScaleTransform()
 {
     ScaleX = scaleFactor,
     ScaleY = scaleFactor,
     CenterX = centerX,
     CenterY = centerY
 };

where centerX and centerY are the values you have calculated in order to show the scaled book in the position on page you would want it to appear.
