Signature Block

Post by arkstar »

I've reviewed the posts about drawing lines, however it seems it works anywhere on the card.
I'm trying to create a signature block where someone can sign but it is constrained in a defined area.
Any ideas? Thanks!

An image object will constrain paint operations within its rect.

Hi.

Does Richard's comment address what you need? That the user literally "signs" in, like one does at a supermarket, where you sign your name in one of those electronic pads to close a credit card transaction? So the user would paint something into an image area, or sign their name in that area?

I believe that answers my question. Its a app for work orders. The client is required to sign the order.
Thanks!

Hi again,

I'm not getting something correct. The code doesn't work on an image. It's just to write their name as an acknowledgement of service.
Do you have a sample routine you could share? Thanks

I put this in an image area script:

Code: Select all

on mouseEnter
   choose the pen tool
end mouseEnter

on mouseLeave
   choose the browse tool
end mouseLeave
And it appeared to work OK.

Sorry, but one more question... Is there a way to clear that drawing?

Thanks Klaus,

That erases the whole img. I just want to clear the writing created with the pen tool...

Hi Rob,

ah, I see, but I'm afraid this is not possible right out of the box.

Quick thought:
You may need to save every modified "snapshot" of your image maybe "on mouseup" so you can
"return" to each last state of the image. Know what I mean?

But I have no idea WHAT state (how many "mouseups" ago) actually reflects the last complete signature.

However that should not be a problem at all, if the signature is the only "content" of that image!
Not?

Hi...

This will work for you... just sign your life away !
all you would have to do then, is export a snapshot of the signature to wherever it needs to go :-)
