One day I could do that, but now it is not practically possible.
This is not just because it is all in fortran (77) but mainly because it is part of a larger integrated system that revolves around a database. Rather: a database-like structure of files.
The principle behind this application is that for every pixel in the image I define a 'mask' with 8 bits.
These bits encode whether the pixel has: ink (writing vs. drawing), paint, both or neither, or whether it is outside of the net page. Not all of that can be automatically detected. The file of mask bits is itself a BMP file, and all of my software reads and writes BMP files only. These are bulky but their access is straightforward.
There is one set of tools to set up the mask file (always 'under work'), and then another tool to use the mask with the image to create a 'derived image'. That second tool is the easy part.
