Hi,
I have looked at the PDF file. It looks as if text in all the pages were
scanned as images. I am certain that one cannot extract text from (text
scanned as) images using PDFBox. Could someone correct me if I am wrong.
You are correct. The pdfs consists of scanned text and yes pdfbox can't extract
I've to corrrect myself. There is no single image containing the scanned text.
It consists of thousands of small lines, like the following 3 ones:
319.5 3175.84 m
319.5 3175.84 l
S
353.5 3175.84 m
353.5 3175.84 l
S
376.5 3175.84 m
376.5 3175.84 l
S
So if you want to use an image to an ocr software you have to use PDFToImage

that text, but the images. Those could be used with a OCR-software to get the
text. I didn't try that but it should work, more or less precise.
BTW: It is always a good idea to extract the text using the acrobat reader. Just
select the text a copy and paste it to an editor. If that doesn't work it most
likely won't work using PDFBox.
Thanks,
Stephen

Subject: Can't extract text Adobe-WinCharSetFFFF-UCS2
Hi, I'm having some troubles extracting text from some South Korean PDF
files using PDFTextStripper. When I try I get a "severe error could not parse
predefined CMAP file for'Adobe-WinCharSetFFFF-UCS2'" message and then
gives me some gibberish. File opens and displays fine in Adobe reader.
I'm using pdfbox-app-1.7.0.jar.
Here is a link to an example PDF that gives me trouble:

Any ideas?
