Signature display

ColinRule

I am looking to use this control.
I can see how you would sign, and save the image, eg as a bitmap.

I am looking to redisplay the signature, but cant see that there is a method or property for this.
The idea is that I have a signature box on my users screen, enabled for the current user only.
They can save, and the signature is saved, but when the user calls up the screen again, I want to see the signature in the box again.

I can have a workaround where I can use the OI bitmap control or SRP picture control, to show this, but then I have to have two controls, one to show the current and one to allow the user for a place to sign.

Is this possible, or do I need to follow up the workaround.

Basically I want an Import from Bitmap method.

Thanks

Colin,

That is an excellent suggestion...and by that comment I am confirming that there is no property or method that will do this for you. I will consult with my developer on the feasibility of adding this but it might not be until next week as he is on holiday right now.

There is no import available because it is not trivial to implement. Therefore, the Signature control was not meant to be a data control that can read and write the signature data. It is an input control that produces images. If you want to display the signature in a readonly fashion, then the Picture control does this nicely.

Thanks, no problem.
What I will do is have the picture control and the signature control on the same form, and toggle visibility.
The user can click a button to sign, make the signature control visible, then when done I can hide this and revert to the picture control.

Actually, thinking more on this I now beleive it is better NOT to allow the control to display.
If you can display it, then someone could edit it, rather than having them re-sign.
Not that this stops anyone from editing the saved image file, but its a level of security.
