csaxs_bec.bec_widgets.widgets.xray_eye.x_ray_eye.ImageZoomControl#

class ImageZoomControl(parent=None, image_widget: Image | None = None, *args, **kwargs)[source]#

Bases: QWidget

Discrete zoom controls for an Image widget’s view.

Mouse-wheel zoom steps can be far too coarse to use precisely over a remote desktop connection, so this provides explicit zoom in/out buttons plus a “fit to view” button that resets pan/zoom to frame the current image (the same operation as XRayEye.reset_zoom()).
