read color data at one pixel

Question

Hello everyone I need to read the data of an image into an array. My array is a 3-dimension array first dimension is the width corresponding to the width of the image second dimension is the height . The third dimesion is the Color Depth of the image I convert image color format to 24bit RGB ( 3 bytes -> 3 elements for each width and height coordinate). The problem is how to read the color data at each pixel of an image ? I tried some properties of Image class but can't find the way out. Please help thanks.

Hi Have you look into .NET System.Drawing.Imaging PixelFormat Enumeration? Specifies the format of the color data for each pixel in the image. I am not sure about directx :( Hope it helps. Cheers.
