The page layout will get lost. Nevertheless, the following three steps help you to convert multipage PDF files to a single text file: $ convert -density 150 foo.pdf ./tesseract/tmp/p%02d.tif $ montage.exe ./tesseract/tmp/*.tif -tile 1x -mode concatenate ./tesseract/tmp/foo.tif ...
$ convert -density 150 foo.pdf ./tesseract/tmp/p%02d.tif
$ montage.exe ./tesseract/tmp/*.tif -tile 1x -mode concatenate ./tesseract/tmp/foo.tif
$ tesseract.exe ./tesseract/tmp/foo.tif output -l eng
For reasons of simplicity the TIF files p00.tif to pXY.tif will get concatenated together to a single TIF file, that has the width of a single page and the height of XY pages. In such a way at least the order of the text or the text flow respectively will be preserved. But one could also concatenate a mosaic of all the TIF files. The density of 150 (dpi) gives reasonable results with tesseract.]]> Navigating the Maze of Free and NonFree Licenses http://circle.ch/blog/p1844.html 2008-01-02T08:31:03+00:00 urs (mailto:urs@circle.ch) General 1844@http://circle.ch/blog/index.php Greg London issued a first draft of his new book [1]: The Libre Labyrinth describes an objective way to understand how various FLOS licenses work, and how different FLOS licenses compare to one another.

Debian läuft in aller Ruhe auf einem Linksys NSLU2. Die Musikdaten werden mittels Fuppes (A free multiplatform UPnP (TM) A/V Media Server) den Endgeräten bereitgestellt. Fuppes war leider (noch?) nicht als ".deb" Datei für die ARM Plattform verfügbar, hat sich aber compilieren lassen. Einziges Sorgenkind ist die 2.5 inch HDD - hier wäre ein RAID oder dergleichen wohl noch ganz vernünftig, allenfalls könnte auch rsync auf eine andere HDD dienlich sein. Die Musik wird über ein BKS Homenet sozusagen frei von WIFI-Strahlung übertragen.

The challange was to share a common folder. The documentation was pretty clear about it; but still it did not work. Now it does. In the guest system, a simple 
c:\>net use x: \\vboxsvr\myshare
did the job [1]. There is no need subsitute vboxsvr with 10.0.2.2 or 192.168.0.2 or something like that. myshare is the name of the shared folder located on the host system.

LaTeX as outlined by Stefan Lagotzki [1]. But a solution to apply more easy was needed. Imagemagick's "composite" does now the job quite well. Multipage PDF files have first to be split up and then being treated with composite as outlined below:
$ pdftk A=multipage.pdf cat A1 output multipage.1.pdf
 $ pdftk A=multipage.pdf cat A2 output multipage.2.pdf

The commandline below takes the singlepage PDF at a resolution of 300dpi and resizes it to a percentage and then glues it to the header page, which is of the size A4. Resizing ensures, that the header information is always visible above the included singlepage:
$ composite -density 300 multipage.1.pdf -resize 93% header.ps -compose bumpmap -gravity south out.pdf

The header page could look like shown below:
%!PS-Adobe-1.0
