Multi-Page PNM Files

Hi,

     Recent (development) versions of netpbm can take multi-page (multi-directory) TIFF images and create multi-page P*M files from them. Does ocrad by chance handle multipage documents?

Thanks,

-Kieran S. Hagzan

Yes, ocrad 0.14 can read multipage PNM files. Either independet files
concatenated together (every one with its own header), or merged under a
unique header as pnmcat does.

Hi,

     I also must say -- hats off to you. I have been doing alot of research lately with OCR engines including many closed-source proprietary engines (as not to shame their developers, I will leave them nameless as I have found the general stability of the code unacceptable.) In this process I tend to do my own dithering, despeckling, and Minkowski dilation/erosion as the proprietary engines tend to have less memory issues (segfaults, leaks, etc. that way.) ocrad in most cases, produces text comparable with those expensive, proprietary OCR methods, and in some cases (namely color images that have been converted to bitonal) actually produces better results. I am impressed.

Excellent work,
-Kieran S. Hagzan
