Converting PDF to multiple PNG-files

So, to convert a png to multiple PNG-file you can use imagemagick like this :

$ imagemagick <file.pdf> <output.png>

It will however do the numbering without prefixing the correct number of zeros (0,1,2,3,4,5,6,99,100 etc-). If what you want is to have a sequence like this – 000,001,002…..010,011,012….0100 etc then you can do like this instead to always have at least 3 digitst on the numbers :

$ imagemagick <file.pdf> <output%03d.png>

WINS name resolution on Ubuntu 14.04

To get windows name resolution on Ubuntu 14.04 remember to install libnss-winbind package. It will work out of the box after that.

 sudo apt-get install libnss-winbind 

Additionally add “wins” to the end of the hosts:-line in /etc/nsswitch.conf. My file looks like this.

hosts:        files mdns4_minimal [NOTFOUND=return] dns wins

when that is said there is a bugreporte on launchpad
