int gocr_charEnd ( void )

closes a new character structure. Long description; adds to the character list. See also: gocr_charBegin(). Returns: 0 if OK, or -1 if error.

int gocr_charSetAllNearPixels ( int action, int x, int y )

set/unset all pixels near this one as part of the character. Long description. Parameters: action   If 0, unsets; if 1, sets. x   The x coordinate of the pixel. y   The y coordinate of the pixel. See also: gocr_charBegin(), gocr_charEnd(), gocr_charSetAttribute(), gocr_charSetPixel(), gocr_charSetRect(). Returns: 0 if OK, or -1 if error.

int gocr_charSetAttribute ( int action, char * name, ... )
