C# Bitmap Imaging

[masood009]

Hi,
I have been trying to create a bitmap image at run time. I have a limited knowledge and understanding of C#.

I want to do the following:

1) Create a bitmap with 698 rows and 72 columns in it.

2) then give a color to each cell of bitmap using my defined criteria. The color can only be red, green or black or between it ranges among these three colors.

In short, i want to create a heat map which look likes image present at the following link:

Create an instance of the bitmap class. The arguments will take a width and height attributes.
You can then use the .SetPixel() function to set the pixel at x,y to a given Color.
