Signature Capture Save Webdirect on Mac

Question asked by washes5 on Mar 23, 2018
Latest reply on Mar 23, 2018 by Karen

I found a custom function for capturing signature in Webdirect on a Mac.  The signature works fine, but I cannot get it to save.  Any guidance would be appreciated.  Here is the custom function:

 

// FMEasySignature v1.0

// http://fmeasysignature.com/

// Developed by Tim Dietrich and provided under an open source license.

// Uses "Signature Pad v1.3.3" by Szymon Nowak. https://github.com/szimek/signature_pad

// Settings.

 

 

// backgroundColor: Color used for the background, as an RGB value. Example: rgb(255, 255, 255)

backgroundColor = "rgb(255, 255, 255)";

 

 

// minWidth: Minimum width of a line. Recommended: .5

minWidth = .5;

 

 

// maxWidth: Maximum width of a line. Recommended: 2.5

maxWidth = 2.5;

 

 

// penColor: Color used for the pen, as an RGB value. Example: rgb(0, 0, 255)

penColor = "rgb(0, 0, 255)"; // Color used for the pen, as an RGB value. Example: rgb(0, 0, 255)

 

 

// instructions: Optional instructions, displayed between the save and clear buttons.

instructions = "Please sign above.";

 

 

// fmpurl: FMP URL to use when the "Save" button is clicked. Example: fmp://$/FMEasySignature.fmp12?script=Example - Save Signature to Container

//fmpurl = "fmp://$/FMEasySignature.fmp12?script=FMP URL Handler - Save Signature to Container" // FMPURL to use when the "Save" button is clicked.

//Added to compute filename automatically

fmpurl = "fmp://$/"&Signatures::TheFileName&"?script=FMP URL Handler - Save Signature to Container" // FMPURL to use when the "Save" button is clicked.
