Mouse wheel zoom

Hi Alex,

I've create my own Zoom VisualTool which I am using with the AnnotationViewer.

The zoom works similar to the standard except it is relative. eg each time you zoom the image doubles in size.

I'm trying to implement a MouseWheel zoom as well by subscribing to ImageViewer.MouseWheel in the constructor of my zoom tool.

Unfortunatly the event only seem to get raised after the first time you click somewere within the viewer control.

Any ideas how to fix this.

Hi Aaron,

You should set focus on AnnotainonViewer.

In code after string:

Code: Select all

 annotationViewer1.CurrentTool = _customZoom;
insert the string below:

Code: Select all

Sincerely, Yuri
