Coding help needed

[Bleek II]

Hi, I need help with a number of issues. First I'd like to say that I have looked a large amount of sample code and have not been able to find the answers.

I have a loop like this

    ColorBgra CP;
   for(int y = rect.Top; y < rect.Bottom; y++)
   {
       for (int x = rect.Left; x < rect.Right; x++)
       { 
         CP.R = ????????????????????;
           dst[x, y] = src.GetBilinearSample(
               x+CP.R,
               y+CP.R,
               true
           );

In place of the ??????????? I want to assign the Red value of the current pixel that I'm working on.

Even better yet the it's brightness; I just used red because I'm working with BW images.

I'm have only used c++ in the past so this a little harder to learn for me.

CP.R = src[x,y].R;

yes but you need to give CP a value first, I think!

void Render(Surface dst, Surface src, Rectangle rect)
{
  ColorBgra CP;
  for(int y = rect.Top; y < rect.Bottom; y++)
   {
       for (int x = rect.Left; x < rect.Right; x++)
       { 
         // give a value to the pixel (not only the red chanel)
         CP = src[x,y];

         // then you could use any chanel of CP as you need!
         dst[x, y] = src.GetBilinearSample(x+CP.R, y+CP.R, true );
       }
  }
}
