Zoom in and out button from the standard toolbar

@lassoan @cpinter
Hello. I am trying to create zoom buttons. Basically, these buttons will zoom in and out the loaded Dicom data in a particular view (red slice, yellow slice, green slice).

It will be a simple zoom in and out. Like; if the red slice view is selected then by clicking on the zoom in (+) button it will be zoom in to 110 %. To zoom out click on the zoom out button (-) to go back to normal. If another view (let’s say yellow slice) is selected then the zoom value (default 100%) will be replaced according to that view.

please guide to develop this feature.

Try to follow this process. Let us know if you get stuck.

how to do the same for brightness and contrast?
trying to design and have buttons for it rather than mouse controls

Also how can I decrease the options in the layout toolbar?

Please advise many thanks

In this case the buttons will need to set these values after disabling auto window/level.
