The document defines structures and variables for generating and manipulating bitmap images. It includes headers for file input/output and complex math functions. Physical parameters like particle energy and output type are defined. Functions are defined to clear the bitmap, set pixel colors, and assign colors based on numerical values. The bitmap will be saved to a file defined by the variable BitmapFile.
