any ideas on this? been trying to implement it with the Windows 7 Multitouch .NET Interop but using this disables the built-in panning and haven't been able to get as "smooth" panning with the multitouch gesturehandler.

Hello,

Multitouch will be supported next year through native WPF controls. Work is in progress...

With best regards,

Loïc

Touch Screen Multi Touch Support

Does gdPicture support multi touch commands (i.e. Pinch to zoom)? If so, where can I find information.

Thanks

Hello,

This feature works in WinForms, but not in WPF yet.
WPF and WinForms handle touch events differently. WinForms have no direct support for touch events and therefore are interpreted as standard mouse events. Because of that, for example, the functionality to move thumbnails is working very similar as when used with a mouse. WPF on the other side supports touch events and they are handled separately from mouse events. You need to handle the "Manipulation" events and "Touch" events - ideally interpret them as mouse events as WinForms do.
Updating our WPF sample to show you how it works is already reported, but it has not been addressed yet due to other priorities.
Kind regards,

Gabriela
