I'm sure this is a simply task but i am not sure how to do it ....
I need to write a simply app that allows someone to draw freehand a signature (of course in a touch screen monitor or Windows tablet).
Is there a simply Delphi example that shows how to do it ?
I have been looking something in the Imageen demos. I have found the ImageEn Paint app but i see that if i move the mouse a bit faster while drawing (simulating someone that is signing) i don't have a continuous curved line; i have a dotted line that i don't like very much... there's too much space between a dot and the next.

thanks

A demo that was designed precisely for this purpose can be found here:

This demo responds to touch and mouse painting and has a very fast brush. It has not been tested on tablets.

The demo app. Fast Brush Painting posted by William Miller (thanks a lot) in the "User Demos and Applications" thread seems to do what i need.

Please let me know if it functions correctly on tablets you test.
