key_color_image
Command line app for creating a particular color scale to images
It is a command line application to which you can pass a color, and the application transforms the input images to that color scale image (as if it was a gray scale, but that color instead of gray)
In addition, the application allows you to set the global alpha of the image, and translate a particular color to a totally transparent alpha
You can also disable alpha component, just in case the input image is a .jpg, or there is any restriction that makes the output image from being saved successfully
If you do not know the color code, you can pass a color: -color input and the application will let you move the mouse on the screen, and when you press return, the color of the mouse pointer will be picked.
