Thanks Matthias.
>From whats been said perhaps the way to go is to make a C wrapper to the C interface to the latest version of ImageMagick and then go through the FFI to interface to Racket. Also someone mentioned the use of parallel processing. It seems to me that an OCR application would be the ideal application for parallel processing. I.e. the analysis of one letter is completely independent of the analysis of another letter. So for example if you had a dual core processor with multithreading enabled you could analyse 4 letters concurrently etc. by setting up 4 threads. Is it possible on a PC (windows or linux) in Racket or in fact in any language (even assembler) to check if it has a multi-core processors and how many cores and/or multi-threading enabled. In which case you would know how many threads to set up to process letters in parallel?
