C# Overtone/Harmonic plugin for Paint.Net+CodeLab

The task is to define a function in a C# file. The C# file should be buildable by the CodeLab plugin of Paint.Net. See here for more info on CodeLab and Paint.Net. http://www.freelancer.com/projects/NET-Windows/Simple-Plug-for-Paint-Net.html The mentioned function should take a "note" structure (see below), overtone count, a line width (in pixels), distance (or "gap") between the first two tones (in pixels), and Color (as [login to view URL]) understands it. Here's a prototype for the desired draw function: void Draw(Note note, int overtoneCount, int lineWidth, int firstGap, Color color); enum Letter { C, D, E, F, G, A, B; } struct Note { Letter letter; int octave; int semitoneOffset; // like -1 would mean "flat" and "1" would mean "sharp" } Attached is a simple example of what I think it would probably look like. Here's some more info on overtones, you should grab the formula from there. Make sure to translate the [login to view URL] into the right frequency (even given the semitone offset). Use the most typical tuning schema that exists for Western music. [login to view URL] Frequency Order Name 1 Name 2 Name 3 1 · f = 440 Hz n = 1 fundamental tone 1st harmonic 1st partial 2 · f = 880 Hz n = 2 1st overtone 2nd harmonic 2nd partial 3 · f = 1320 Hz n = 3 2nd overtone 3rd harmonic 3rd partial 4 · f = 1760 Hz n = 4 3rd overtone 4th harmonic 4th partial Include a sample so that the function is actually exercised when the CodeLab filter is applied from [login to view URL] itself. Middle-C would be fine. You might even include an example that included two overtone stacks (like one for middle-C and one for G in the same octave) of different colors (say the Primary and Secondary color from the [login to view URL] environment) :) Thanks!
