      1. which symbology are you using?  how many characters in the symbol?  what is the aspect ratio?  rotation sensitivity increases with the length and aspect ratio of the symbol.
      2. how large is the symbol in the image?  rotation relative to the pixel grid also increases the resolution requirements.
      3. if you grab the latest code from svn (r99) you may get better results by increasing the scan density

      if you attach your image to a support request we can tell you specifically what the problem is...

        45 degrees is not going to work.  10 might... the actual maximum rotation depends on the length of the data and the quality of the scan

        yes - the latest code has a feature you might use to decrease sensitivity to rotation

        we're in the middle of a project name change; the next release will be made as soon as that stabilizes.  i'm expecting within the next week or two

        configure/build infrastructure is generated by autotools.  see HACKING for instructions - basically just run:
        # autoreconf --install

        assuming you have recent enough versions of autotools (if you get errors, you need to upgrade)

      hmm

      autoreconf --install dosent work, i habe the last version of "autoconf-dev" on my Ubuntu Server

      i get:
      administrator@lap11:/opt/zebra/zbar/trunk$ autoreconf --install
      autom4te: cannot open autom4te.cache/requests: Permission denied
      aclocal: autom4te failed with exit status: 1
      autoreconf: aclocal failed with exit status: 1

      OK OK "sudo"

      Than i get:
      administrator@lap11:/opt/zebra/zbar/trunk$ sudo autoreconf --install
      Makefile.am:7: Libtool library used but `LIBTOOL' is undefined
      Makefile.am:7:   The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'
      Makefile.am:7:   to `configure.ac' and run `aclocal' and `autoconf' again.
      Makefile.am:7:   If `AC_PROG_LIBTOOL' is in `configure.ac', make sure
      Makefile.am:7:   its definition is in aclocal's search path.
      autoreconf: automake failed with exit status: 1

      I think i need a new version for better results, my Code you can see in topic "wich DPI?"

      i don't think you are picking up latest versions.  note that there are three autotools required: autoconf, automake and libtool.  what do you get for these versions?

      # autoconf --version
      autoconf (GNU Autoconf) 2.61

      # automake --version
      automake (GNU automake) 1.10.1

      # libtool --version
      ltmain.sh (GNU libtool) 2.2.6

      now i have update all...

      # autoconf --version
      2.61

      # automake --version
      1.10.1

      # libtool --version
      2.2.6

      and i get the Newest SVN...
      but the Same...
      als Root, ore as normal User...

      root@lap11:/opt/zbar/trunk# autoreconf --install
      Makefile.am:7: Libtool library used but `LIBTOOL' is undefined
      Makefile.am:7:   The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'
      Makefile.am:7:   to `configure.ac' and run `aclocal' and `autoconf' again.
      Makefile.am:7:   If `AC_PROG_LIBTOOL' is in `configure.ac', make sure
      Makefile.am:7:   its definition is in aclocal's search path.
      autoreconf: automake failed with exit status: 1

      :-(

      ok, i don't understand why you're getting this error.  we could try to figure it out, or...

      > the next release will be made as soon as that stabilizes
      >
      try the 0.7 release, which should be consistent with the latest svn.  the configure script is included with the release

      thanks,
