Using a color bitmap and a horizontal color-bar, with all color levels ranging from left to right, data can be extracted from any image.
The colorbar is used to generate an equivalent set of gray levels and the RGB components are properly converted to gray levels.
Afterwards gray values are properly scaled to the interval of numerical values specified by the user.
This tool can be used to recover numerical data from digital images when the original data is not available.
