Zoom preview for curve bend filter

Question

Is there a way to zoom the preview image for the curve bend distortion filter in Gimp 2.8?

Answer 1

Unfortunately no. The dialog uses a simple preview widget which does not allow zooming.

For what it's worth: some plug-ins have been updated to use a newer preview widget with zooming capabilities, eg. Filters > Light and Shadow > Lens Flare (Lens Flare Dialog). Perhaps some developer in the future upgrades the dialog and replaces the basic preview with a zoomable one.
