Feature Request: Pinch to zoom

**andheum** · March 14, 2019, 8:38am

Hi all -
one small request for a “missing” feature that has been driving me crazy in the mac environment - it would be great if on a trackpad, one could pinch to zoom in and out of the GH canvas. In most other respects the GH canvas behaves like a parallel viewport in Rhino - two-finger drag allows you to pan, etc. - but being able to pinch to zoom would feel so natural, it’s a shame it’s not currently possible.

This is working in the latest RhinoWIP for Rhino 6 for Mac. We needed a newer version of Xamarin.Mac in order to get this working.

This is a beautiful thing in Rhino, and it would be great to see it in GH.

This has been a huge improvement HOWEVER I have one further request @dan The pinch-to-zoom center seems to have its Y flipped. a pinch at the bottom of the canvas zooms into the top and vice-versa.

Yeah, that’s broken. This feels like a recent regression. Logged in RH-50793. Thanks for reporting!

Hi Dan pinch to zoom nice, but how about when the Scroll Zoom in GH canvas will be fixed?
This need to be in the same direction as RHINO

We have that request on the pile logged in RH-36624. It was requested over in this topic.

Pinch to zoom should work better in the latest RhinoWIP. Please give it a whirl.
