Ocropus Error report

[Dibyayan Chakraborty]

Hi,
I am new to ocropus and encountered the following problem.
I ran "ocropus-gpageseg" on output binary image of  "ocropus-nlbin".
But i am getting the following error report.

output/0001.bin.png
scale 16.5831239518
computing segmentation
computing column separators
computing lines
propagating labels

number of lines 60

    raise e
ocrolib.toplevel.CheckWarning:
CheckWarning for argument image of function <function write_page_segmentation at 0x273bde8>
<ndarray-2500180 (560, 698) int32 [0,65583]> of type <type 'numpy.ndarray'>: excpect a page image (larger than 600x600)(This can happen occasionally during normal operations and isn't necessarily a bug or problem.)

And there is no line written in the subfolder.
Please explain what is the meaning of this report ?

I'm having this problem too. I think it means your image isn't large enough to represent a page, ie the 560 in (560, 698) should be at least 600. I'm not sure how to override this though, or what other tool to use to process images that only represent part of a page.

If that indeed is the case then perhaps scaling may be a way to increase the size. But I wonder if it is a bug or it is kept for some reason.
