This addon has ImageMagick command line converter included in it which is used to resize the images.  The following formats of images are supported for resizing:

• JPEG / JPG
• PNG
• TIFF
• BMP
• DPX
• EXR
• GIF
• SVG

Here are the instructions to use this addon:

1. Download the addon from here and save it to hardrive.
   
2. Next install the addon into Thunderbird.
3. You can then change the options of the addon to change the resolution of the image(optional step).
4. When you compose a new email with images as attachments, the following message will pop up:
5. Select “YES” to have the images resized to the resolution selected in the addon options.

Now the mission is to ship the small program with the addon and get the images attached in the email to run through this command line program.

The resizing syntax for imageMagick is as follows:

convert.exe source.jpg -resize 600×600 target.jpg

Now to do the same using nsIProcess, I needed the path to the convert.exe program which I had placed inside the component folder of the addon, here is how I got the path:

var getPath = Components.classes["@mozilla.org/file/directory_service;1"]
.getService(Components.interfaces.nsIProperties)
.get(“ProfD”, Components.interfaces.nsIFile);
getPath.append(“extensions”);
getPath.append(id);
getPath.append(“components”);
getPath.append(“convert.exe”);

var path = getPath.path;

Next before getting the nsILocalFile using this path, we must change all instances of slash \ to double slash \\. Very Important step, learnt it the hard way.

path = convertpath.replace(/\\/g,”\\\\”);

// create an nsILocalFile for the executable
var file = Components.classes["@mozilla.org/file/local;1"]
.createInstance(Components.interfaces.nsILocalFile);
file.initWithPath(path);

// create an nsIProcess
var process = Components.classes["@mozilla.org/process/util;1"]
.createInstance(Components.interfaces.nsIProcess);
process.init(file);

After this all I needed to do is call run the process with the appropriate arguments:

process.run(false, args, args.length);

The issue that was happeneing here was the paths. The source and destination images need to have the absolute filenames else the resizing does not work. That took me some time to get running, but I think now I have got it working. The complete code will be released soon in 0.3 await it, little more polishing is needed.

The lecture made me realise why Mozilla has stressed on the use of Javascript and the BIG chunks of complex code that Javascripts shields us from. After this lecture I really appreciate the use of javascript.

So the next question that arose in my mind is whether I can ship a command line program with an extension and use it. I posted the question in the mozillazine forums here. The response was positive and I was redirected to a very helpful page on Mozilla development.

Now I need to see if it is possible to send the .exe with the extension and issue commands on it. Anyone done stuff like this???

My addon can be found on my wiki page: zghansar.

The reason is so embarassing …

After compiling when I move into “obect directory/dist/bin” I was typing “firefox” which was starting an instance of the firefox installed on the system and not the newly compiled Minefield. All I had to do was run the command as “./firefox” and that started the minefield with the tab behaviour change.

Although the tabs were opening next to the active one, just like everyone else, the closing of the tabs is a problem, the issue is how the tabs are stored in the array, this needs to be modified.

The patch file is on my wiki page.

For most part of FSOSS I was attending the education track, this is because of my volunteer work I do outside for educational institutes and they require the use of Open Source products like Joomla, Moodle and now after FSOSS I added Drupal to my know-how. Drupal is a much smaller community than Mozilla but it has its own way of going about things (may I dare to say that the look of their bug handling system is better).

During FSOSS I really understood how important and awesome David Humphrey’s Open Source classes are, the length to which David Humphrey has gone to make us understand the methodology and the way Open source communities work. The real outcome of this course I feel will be after finishing this course, the way the students will continue inside the community.

Lastly I cant wait for the videos of FSOSS to be released. As everyone of us have missed more than we atteneded

Finally I came up with the easiest but very important contribution in my opinion. Hoping for some peers to jump on it.

you think you can contribute ??? go ahead….

See you all at FSOSS
