Set Parameters for recognize OCR by FindLinesCreateBlockList()

[Rosario Gironda]

Hi all,

I need to set the following parameters:

max_nonspace, min_space, space_size, kern_size, space_threshold.

I have tried to edit this parameters by FindLinesCreateBlockList() function and created TO_BLOCK for edit, but after I have called the FindLinesCreateBlockList() function , I can't recognize the text and when call GetUTF8Text() function  the following error occurs : exception: access violation reading 0x00000000.

Why? Solution?

Thanks
