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.
