[Bug-ocrad] possible bug in OCRAD_result_blocks return value

[João M. S. Silva]

Hi,

I'm using the API. Since I'm not requesting layout analysis, I was writing:

  int num_lines = OCRAD_result_lines(api, 0);

assuming OCRAD_result_blocks was always 1, i.e. that block 0 always existed.

But it looks like in some cases OCRAD_result_blocks is 0 and therefore 
calling OCRAD_result_lines(api, 0) gives an error.

Maybe this is not a bug, but simply a functionality misunderstanding. In 
the description of OCRAD_result_blocks, instead of:

  "Returns the number of text blocks found in the image by the layout 
analyser or 1 if no layout analysis was requested."

should we read:

  "Returns the number of text blocks found in the image."

?

Thanks.
