charRecognizer

This is the core of the OCRing. This module, using some ingenious algorithm, must be able to find that the bitmap it processed is a certain character. Prototype:

void gocr_charRecognizer ( gocrImage *pix, gocrBox *b, void *v );

pix is an image of the framed character, whose structure gocrImage is described in section [*]. There are two reasons to prefer to access pix than the get/setData: first, the former is much smaller, and will be entirely in the processor's cache, therefore being accessed much more quickly; second, the former starts on 0, while you'll have to add b->x0 and b->y0 to the latter. Of course, you may still use the set/getData functions.
