//     Demo imageJ script to control SharpCap and then filter the resulting image background
//     It can open an imageJ GUI, then create a Windows .bat file to launch SharpCap with its *.py script
//     This is only a demo, and not intended to be useful as is. 
//     The full version generates the .bat and .py files, and has a complete interface to control SharpCap
//     This script was developed from http://rsb.info.nih.gov/ij/macros/tools/VideoCaptureTool.txt 
//     The imageJ Macro language is described on https://imagej.net/ij/developer/macro/macros.html
//     The imageJ Macro functions are described on https://wsr.imagej.net/developer/macro/functions.html
//
// (1) Download ImageJ bundled with Java 64-bits for Windows https://imagej.net/ij/download.html 
//     If you already have Java installed, you can just download the imageJ ZIP archive
//     Use the Command Recorder (Plugins>Macros>Record) to see what the imageJ menu commands do
// (2) Create D:ShapCap.bat="C:\\Program Files\\SharpCap 4.1 (64 bit)\\SharpCap.exe" /runscript D:\SharpCap.py
   (3) Create D:SharpCap.py=SharpCap.SelectedCamera.CaptureSingleFrameTo ("D:\image.fits")
// (4) Copy this SharpCapTest.txt file to ImageJ\macros\toolsets 
// (5) Click the red >> icon in the ImageJ toolbar and select this SharpCapTest.txt tool
// (6) Right-click the new camera icon to set the parameters to remove diffuse BG
// (7) Left-click the new camera icon to launch SharpCap, capture an image, and remove diffuse BG
// (8) Eventually edit the commands below, select this tool again with the red >> icon and relaunch
// (9) Clear the camera icon tool by selecting "Startup Macros" with the red >> icon
//(10) NOTE: The image is captured with the last camera and its settings eg (Camera V3 Simulator)
