Hey my friends :rp:
I have an android app where Customers can put a signature in an image control
But how can i test if there is really a signature ?
I have tried :
Signature is an image = img_control
Signature ..valid,
Signature ..height
In the simulator all works fine (off course) but not on the tablet
TIA !!

Hi Jan
what is a signature? Is a dot valid? an X?
What you can check is ..modified, or check the size of the resulting (saved) image on disk, and compare that to the size of the same field saved empty...
However, none of that will tell you if there is really a signature
Best regards |

Hi Jan,
how do you hande the drawing of the user?
I'm using the pen down/move/up events together with dLine() to get that done. And I also use a boolean in this proces to indicate that at least some drawing has been done. |
