It’s pretty simple, the signature pad had an app that could be launched to collect a signture.
The app supported a user-specific properties file, which I copied into the correct place from the Resources folder. These properties also affected launching the signature app from Scriptel’s Adobe Reader plugin for PDF signatures. The app also supported being launched with command line options that could override those properties, and one of the options forced it to quit after collecting a signature or canceling. If you launch with the ‘open’ command, LEP will return immediately, but I executed the binary buried in the application package (Contents/MacOS/binaryname) so LEP waited until the application quit. So in 4D the process is: — make sure the destination file does not exist — launch the app with LEP — check for the destination file; if it doesn’t exist user cancelled. The best way to see if this will work for you is to test by launching on the command line (Terminal on macOS). If your shell does not give you a promp until the app quits, then this might work for you. The option that forced the Scriptel app to quit after accepting/canceling is for plugin mode (--plugin). The Topaz may work similarly, especially if they have plugins that allow you to collect signatures in Excel, Word, or Adobe Reader.
