Allow zooming when drawing be activated in the Syncfusion PDF editor

Hello. For now, no zoom function available during any annotation mode. 

I wonder what our options are here. Can we control it in Syncfusion directly, or should we intercept multi-touch gestures manually, if it's logically disabled, any bottlenecks here?

Andreas, No, we could not control the zooming while in any annotation mode on PDFViewer using syncfusion directly. We have implemented the logic in such a way that zooming should happen while viewer is in annotation mode. However, you could set annotation mode to none to operate zooming functions and start annotation mode after a certain zoom has happened.

Hello. Thank you for the answer. If it has been implemented in some demo, could  you please share it?

Andres, could you please elaborate on the use case scenario of zooming while in annotation mode?

We need the option to zoom the pdf content while in DRAWING annotation mode.  https://drive.google.com/file/d/1jNyYfjDM8rpZ-G4jPL05fwBTrVKkVLWv/view?usp=share_link

Andres, the previously suggested method would be changing annotation mode to none using button click  and using pinch to zoom, which is not suitable for your requirement. We already have a feedback for your requirement though due to other work commitments, we don't have plans to implement this feature.
Please do find the feedback,
