Luckily, some clever programmer wrote a PNGCanvas class that saved the day. Here’s how to use it:

from pngcanvas import PNGCanvas
class ImageTest(webapp.RequestHandler):
 def get(self):
  img = PNGCanvas(256, 256, [0, 0,0,0])
  for i in range(0, 256):
   img.point(i, i, [0xff, 0, 0, 0xff])
  self.response.headers['Content-Type'] = "image/png"
  self.response.out.write(img.dump())

This example runs at http://pngcanvas.appspot.com/image

override public function call(command:String, responder:Responder, ...parameters):void {
 parameters.unshift(command, responder);
 super.call.apply(this, parameters);
}

thanks to the good old prototype ..!

Storing your version information

We will use a simple text file to do that and we’ll call it .version. Its format will be:
major_no
minor_no
build_no
revision_no

Updating the version data

A small python script is used to do that. A build number is incremented each time and the revision number is retrieved from SVN. Here’s the versioner.py script (make sure it’s executable):

#!/usr/bin/python
v = open('.version')
major = int(v.readline().strip() or '2') # can change 2 for any major version number you'd like
minor = int(v.readline().strip() or '5') # idem
build = int(v.readline().strip() or '0') # idem
build += 1
import os, re
ri, ro = os.popen2("svn info", 'r')
rev = ro.read()
ri.close()
ro.close()
revre = re.compile('Revision: ([\d]+)')
revision = revre.search(rev).group(1)
o = open('.version', 'w')
o.write("%d\n%d\n%d\n%s\n" % (major, minor, build, revision))
o.close()

Running the version script

If you’re using Flex Builder, this is easily done:
Go to project properties.
Under the Builders tab, click New
Name it anything you like
Select the versioner.py script in location
Select the folder containing your .version file as the working directory
Check “During manual builds” and “During auto builds” in the Build Options
Once your builder is created, make sure it’s at the top.

Using the version information

You can embed it in your Flex application using the following code:

[Embed(source="../.version",mimeType="application/octet-stream")][Bindable]
 
public var version:Class;

and then you can access it at runtime using a function like this:

public function getVersion():String {var v:Array = String(new version).split('\n');
 
return v[0] + '.' + v[1] + '.' + v[3] + ' build ' + v[2];;
 
}

which will return something like ‘major.minor.revision build’.

Power and cooling being the key issue here, I can’t understand why there is no booming data centers business in Québec, a province with huge water resources, cheap electricity and fiber availability.
