I need a Class to draw polygons in J2ME. This needs to work on the Nokia 7210 phone emulator. You can get a free development kit at in the Java, MIDP section. It's called the Series 40 SDK Beta. This SDK has added objects & methods to do pixel level manipulation of images.

The main function will be passed the following info:
1) The fill color (RGB)
2) The border color (RGB)
3) The border width ( >= 1)
4) A pointer to an integer array which holds bezier curve coordinates. The first integer is the start point, the 2nd integer is the 1st bezier control point, the 3rd integer is the 2nd bezier control point, the 4th integer is the end of the curve. Assume the end of the previous curve is the starting point of the next curve. So the next integer hold the 1st control pt for the next curve, etc. The last point on the last curve will be the same as the first point on the first curve. The array ends in 0, 0, 0.
5) An antialias flag (True = do antialiasing of border line)
6) An Image to draw on.

The way I see this working is:
#1 - Convert the bezier curves into line segments. There's alot of code available on the internet for how to do this.
#2 - Do a standard polygon fill.
#3 - Draw the outline with a line drawing routine. Use some kind of anti-aliasing technique (Wu?).

Since this code will run on a slow phone, any optimizations are greatly appreciated =) For example, super-sampling for antialiasing isn't a good idea because there's not enough memory to make the larger sample. Also, you should allocate all memory at the start in one big chunk instead of allocating as you go. (...I'm talking about memory to hold the line info needed for the polygon fill, or whatever else).

There may be code that already does this.. such as an SVG rendering class or a Flash class. If you can find it great - then I just need it working on the Series 40 SDK version of J2ME.


1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.

2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request.

3) Complete ownership and distribution copyrights to all work purchased.

Windows, J2ME - Use the Nokia Series 40 MIDP Concept SDK Beta 0.2. This is available for free at in the Java->J2ME->Tools section.

That SDK has a Nokia 7210 emulator. You don't need to test it on the real phone.

You can use Forte or JBuilder or other J2ME development environments with this Nokia SDK.

Hi there,

I checked the package and it's comprehensive.

also everything is simple except the bezier curve ... which involves some more complicated formula. but I worked with bezier curves befor ... if you want I can provide a demo.

it will be completed in less than a day.
