Does anyone here have experience using a signature pad to capture a
signature on a web form (intranet in this case) from which the data
entered along with the signature are then entered into a PDF? I've
got a signature pad from Topaz Systems and need to do exactly that.
The form already works fine without the signature. It can be filled
out and upon submission the data from the various fields is entered
into an existing PDF via cfpdfform. Now I need to add an actual
signature.
The Topaz site included some example code with some CF, but I'm lost
on how to tie that into the form. Here's their example code:
<!---
<cfmodule template="/somePage.cfm" pageName="Sign Example">
--->
<cfscript>
/**
*
* @param str
* @return Returns a boolean.
*/
function IsSomeMethod(str) {
return true;
}
</cfscript>
<cfif not IsSomeMethod("Some Value")>
<p>
Press the Sign button to sign. Press the Clear button
to erase the
signature and re-sign. Press the Display Signature String button to
turn the tablet off and display the signature string that is to be
passed back to the server after signing is complete.
</p>
<cfelse>
<cfoutput>
<p>
Press the Sign button to sign. Press the Clear button
to erase the
signature and re-sign. Press the Display Signature String button to
turn off the tablet and display the signature string that is to be
passed back to the server after signing is complete.
</p>
</p>
</cfoutput>
</cfif>

<input id="SigBtn" name="SigBtn" type="button" value="Display

SigPlus1.TabletState(0);
SigPlus1.SigCompressionMode(1);
alert(SigPlus1.SigString());">

When I run that code it seems to work fine. You can use the signature
pad and what you write appears on the screen. I just can't figure out
to get the signature itself to "submit" with the rest of the form.
I'm totally lost at this point.
