ascii85
Ascii85, also called Base85, is a form of binary-to-text encoding developed by Paul E. Rutter for the “btoa” utility. By using five ASCII characters to represent four bytes of binary data (making the encoded size ¹⁄₄ larger than the original, assuming eight bits per ASCII character), it is more efficient than uuencode or Base64, which use four characters to represent three bytes of data (¹⁄₃ increase, assuming eight bits per ASCII character).

BGRABitmap XYZ
XYZ is a colorspace that stores the actual stimulation of the average eye, relative to a max luminance (Y=1) considered as white. Fluorescent colors or light sources may have greater values for X/Y/Z so in this case you would rather use TXYZABitmap floating-point format to avoid saturation. Otherwise, for most use cases, when the image represents an object reflecting daylight, TWordXYZABitmap is sufficient.

C to Pascal
One of the weaknesses of Pascal compared to the C language, is a lower number of existing libraries. The reason for that is the much greater popularity of the C language compared to Pascal. Rather than rewrite the existing C libraries in Pascal, an easier alternative is to use the C libraries from Pascal.
