Splitting characters
GOCR provides a set of functions similar, or better, (almost) identical
to those used to create characters to split them.
Let's take a look of the situation: you have added a character that
you later find out is in fact composed of two (or more, but let's
assume two for simplicity; you can take care of more applying this
procedure several times) characters. How to split them? Although you
could delete the box, taking care of saving its attributes, create
two new characters, etc, there's an easier way to do it:
-
- int gocr_charSplitBegin ( gocrBox *box );
- box
- the box to be splited.
Now you can work just as if you were adding a character. All the gocr_charSet
functions can be used as usual. When you are done, call
-
- int gocr_charSplitEnd ( void );
It's time for the fine print. First, what happens: all the pixels
you select will be part of the a new box. This box is inserted in
the list before the original one, which is updated to hold
the rest of the pixels only. All attributes that were part of the
original box are now transferred to the new one (so, the original
one doesn't have any attributes anymore; but since they are applied
to the box before it, they are applied to it too). You can call gocr_Abort
just as if you were adding a character.
Future: there may be a flag to set which of the
boxes goes before which.
