I’m using the ImageViewerControl

and I want to disable the mouse ptz but using the digital zoom

​

​I did find the infomation from the document

​

enabledigitalzoom
enabledigitalzoom563×133 43.8 KB
Now.. I try like that

view.EnableMouseControlledPtz = false;
view.EnableMousePtzEmbeddedHandler = true;
view.EnableDigitalZoom = true;

​But, I cannot do the digital zoom

​

​So..

​1. How to only enable the digitalzoom on ImageViewerControl?

​2. When I using the built-in digital zoom.. how to off that? how to view original size?

3. If I want to handle the digital zoom not built-in.. Is there any API for handle the digital zoom?

You are doing the correct setup. When digital zoom is enabled, you can use the mouse-scroll wheel to zoom in and out - or you can send Message’s to control the digital zoom. Try see the VideoViewerQuality sample.

I’m sorry, but I think you misunderstood.

I​ want to digital zoom alone. I do not want to do click PTZ.

​

Is it possible?

You can control digital zoom on the UI (with mouse), and by programming.

This can be done in Smart Client or standalone app using the .Net MIP library.

For standalone, try start the “VideoViewerQuality” sample, then tick mark the “Digital Zoom”, and then click the “Rect-Zoom” button - it will digital zoom to some almost top-left quarter of the video.

Late update to this post. Just want to ask what the Messages are that controls digital zoom in a standalone player.
