ImageMagick

Joshua Scotton — Tue, 16 Feb 2010 15:47:30 +0000

Had to split a pdf into seperate jpg files for each page earlier and dug up my notes on how to do this.

convert file.pdf file.jpg

Unfortunately the resolution was messed up in the output files so had to do some digging on google to find this forum post which sorted the problem with:

convert -density 400 in.pdf -scale 2000x out.jpgtext

Works a treat. I had figured out the -scale part but the -density bit I had missed. I’ve also been using another ImageMagick command quite a lot recently to prepare folders of photos for Facebook upload. This one changes the source images so best make a copy of the pictures first.

mogrify -resize 800x *.jpg

Off course, these are linux commands so might not work on Windows.

Audible.com and Linux

Joshua Scotton — Wed, 26 Nov 2008 16:05:51 +0000

I recently contacted Audible.com’s helpdesk to see if they had updated their status on linux compatibility. They hadn’t (i.e. still no support), so I asked the following question:

“Are there any plans to add support for Linux in the future?”

The reply was interesting…

“There aren’t much talks in supporting Linux in the near future and we don’t have much information regarding when it will become available. We will be making a full transistion next year to Amazon.com’s operating systems so anything is possible.”

Hmm, Audible are going to use Amazon’s operating systems. This could be good news if this means that they’ll be going down the mp3 route that Amazon have been using for their music section. Not only would that make Audible’s collection Linux compatible but iit would also open up the number of mp3 players that could play their audiobooks.

Creating Documentation from Python Source Files with Doxygen and doxypy

Joshua Scotton — Mon, 04 Feb 2008 14:01:48 +0000

I was recently generating some documentation from the Entertainer source code and decided to share how I managed to do it.

I’m assuming python 2.4 is installed on your system.

First install doxygen and graphviz

sudo apt-get install doxygen graphviz

Download the latest version of doxypy from http://code.foosel.org/doxypy and extract to a suitable location.

I used doxypy-0.3rc2.tar.gz

Now we need to generate a configuration file, to do this run the following from your project root folder

doxygen -g config.dox

Edit the file and set the following tags:

PROJECT_NAME = #Your Project Name would go here PROJECT_NUMBER = #Your version/revision number goes here OUTPUT_DIRECTORY = #Where you want the documentation going FILE_PATTERNS = *.py RECURSIVE = YES INPUT_FILTER = "python /path/to/doxypy.py" #set this to where you extracted doxypy FILTER_SOURCE_FILES = YES INPUT = #where the source files are

If you want graphs also edit the following:

HIDE_UNDOC_RELATIONS = NO HAVE_DOT = YES CALL_GRAPH = YES CALLER_GRAPH = YES

Run the following:

whereis dot
and enter the output into the following config tag:

DOT_PATH = /usr/bin/dot

Next ones are optional:

MULTILINE_CPP_IS_BRIEF = YES DETAILS_AT_TOP = YES EXTRACT_ALL = YES EXTRACT_STATIC = YES SHOW_DIRECTORIES = YES SOURCE_BROWSER = YES ALPHABETICAL_INDEX = YES COLS_IN_ALPHA_INDEX = 8 TOC_EXPAND = YES DISABLE_INDEX = YES GENERATE_TREEVIEW = YES GENERATE_LATEX =YES
All set up now…

All we need to do now whenever you want to generate/regenerate the documentation is to run the following from the project root folder:

doxygen config.dox

Thanks to internetducttape.com as I used this blog entry as a starting point.

Cowon iAudio D2

Joshua Scotton — Fri, 09 Nov 2007 21:36:07 +0000

Just got a new Cowon iAudio D2 to replace my old ipod and have been seeing how I can get it working on ubuntu linux.

On Ubuntu when the D2 is plugged in it acts like a normal usb memory stick.

Upgrading your firmware wipes the files on your D2 so you need to do this first if your firmware is not up to date
When the D2 starts up it shows the current version number on the splash screen

Firmware and Manual

You can get the firmware from here:

and a pdf of the manual from here:

Applications

A quick search for applications reveals the following flash app links (put them in the FLASH folder)
