Command line chroma key is ideally suited for your scripting needs. You can export your chroma key composited photo either with a transparent background(alpha) or with a digital background of your choice. This brings the power of green screen compositing software to your command line. Power users can use it in scripts for processing hunderds of photos. You can also use it for quickly prototyping a concept and showing it to your audience.

You can install the chroma key command line just like any other software and you invoke it from the command line and pass it parameters like the foreground photo, background photo etc.

Let us know about your bulk purchase needs and we can work out bulk discounts for your organisation.
If you need to use it as a library or green screen API chroma key sdk etc, let us know after you try out the command util. We'll be happy to arrange it for you.


Using the command line compositing for green keying:

====== Instructions for Mac =====

Once you have extracted the .app file, you can invoke it like this.
cd <the folder where the .app file is present>
./chromacmd.app/Contents/MacOS/chromacmd -f foregroundfile -b backgroundfile -o outputfile -alg 3
Note: above command starts with a dot before the slash(/)
-f:  mention foreground image file path (this is the image with the green background)
-b: mention background image file path. This is what replaces the green in the foreground image above.
-o: mention output image file path (.png)
-alg: 1 or 2 or 3 to vary the chroma keying algorithm.

===== Instructions for Windows ====

After you download and install, open windows command prompt and go the directory where ChromaPhoto Cmd is installed. From that prompt.

C:\Program Files\ChromaPhotoCmd>chromacmd.exe -f C:\greenpic.jpg -b alpha -o E:\output.png -alg 1
{-----Installation dir---------}

-f:  mention foreground image file path (this is the image with the green background)
-b: mention background image file path or type "alpha" (without quotes) for transparent background. This is what replaces the green in the foreground image above.
-o: mention output image file path (.png)
-alg: 1 or 2 or 3 to vary the chroma keying algorithm.
