Devnagari Text Compilation in Kile

2009-05-20T05:54:00.000-07:00

Compiling Sanskrit [Devanagari] text in Latex is easy with the Devanagari package that can be found in the Ubuntu repositories. However the input file .dn has to be processesed by the devnag preprocessor which results in the tex file which can be compiled and viewed in your favorite pdf viewer in one click by using the default keyboard shortcut 'Alt + 1' in Kile.

The preprocessing step can be integrated into Kile process by following this simple method so that everything can be a one-click process:

Go to Configure
Create a Tool called SansProcess
In General tab --> Command = devnag
Target = '%S.dn'
In Advanced tab --> Type: Run outside of Kile
Class: Compile
Source Extension: dn
Target Extension: tex
State : Editor

Create another tool called SansBuild

When you create this tool use the QuickBuild tool as its parent so that our Tool can get all those properties at birth.
Add the SansProcess tool that we created to this tool and move it up to the top of the list.
Now all we need to do is to create a keyboard shortcut to access our newly-minted tool easily.
I have used 'Alt + S' on my system.

Enjoy !

Works on Kile 2.0.0 [using KDE 3.5.10]

LInux Tips

2009-01-27T05:46:00.000-08:00

Find the version of Ubuntu you are using.
On the command line: lsb_release -a

Look at these files

/etc/issue
/etc/lsb-release
Convert pdf to jpeg in Linux from command prompt

First you need to have ImageMagick installed in your Linux machine.

To install ImageMagick in Debian, run the following command:

$ sudo aptitude install imagemagick

To convert pdf file to image use the ‘convert‘ command:

$ convert doc.pdf doc.jpeg

convert to tiff

$ convert doc.pdf doc.tiff

If the default output is too low resolution, you can add “-density NNN”, where NNN is a number.

EG: I just did an A4 PDF to a PNG, but it came out too small. To make it bigger/higher res, I did: “convert -density 300 input.pdf output.png”
