Tesseract from git and pdf output

[simon.ei...@vol.at]

hi all,

i compiled tesseract from git yesterday and played with it a little
bit.
pretty impressive what happened since around 2 years.
not only has tesseract a lower filesize but it seems its also faster
and more accurate.

But to the topic of this message:

I used the following command to read from a tif file and convert it
into a searchable pdf:

$ tesseract image.tif -l eng image pdf

which resulted into a text file with the very accurate ocr result and
a pdf.
when i opened the pdf with adobe reader i got an error that something
is wrong with the pdf file i just created.

the pdf was also large around 1 mb. a lot for just a little bit of
text.

am i doing something wrong there?

and i have a feature request as well.
more and more copiers/scanners output in multipage pdf which contain
images of the pages scanned.
is that planned to be included as well to be used as input file?

greetings,
simon

Usually that error comes if pdf.ttf and pdf.ttx are not in your tessdata directory. 

Please check that files from https://code.google.com/p/tesseract-ocr/source/browse/#git%2Ftessdata are there in your tessdata directory pointed by the tessdata_prefix.
