I'm a bit confused. I've come across a program that generates image maps of a certain kind (Lyapunov exponent maps). These images contain information about various single-precision values I'd like to retrieve.

For instance, Pixel 1,1 is some RGB value, which correlates to a given single-precision number. How can I retrieve that info?

Here's the actual 'explanation' from the docs:

The "Raw Image" of the Lyapunov map is formed by storing raw IEEE floating-point "single" values (trunctated from the computations that used double-precision values) as the pixel data in a pf32bit bitmap. The mouse cursor can be used to inspect the value at any point, which is shown below and to the left of the image. In this experiment of displaying floating point values, the floating-point exponent is ignored, and the floating-point fraction becomes the 24-bit RGB value that is displayed.
Can anyone help me extract this info?
