I am trying to make a picture controler on my interface. I can drag and zoom my picture but my zoom is too bad ....
My picture is big and I didn't find the way to make a zoom on the center of my indicator image with the zoomfactor. All my calculate tries failed and my reseachs on the web failed ...
I am not really sure if i am clear but I can answer your questions.

I am trying to use classical touchscreen moves on my LabVIEW application. The problem is I really don't know how read the information coming from Windows indicating the type of move (zoom rotate, span,...)!
I tried to use the Windows message queue library (using user32.dll) with the message WM_TOUCH and WM_GESTURE but nothing works. I don't know if it's compatible...
Does anyone tried to do this?
Thanks for your help!
