Question

Im using the following code to travel though the pixels of a BMP as this

for (int i = 0; i <= Image.Width; i++)
 {
    for (int j = 0; j <= Image.Height; j++)
    {
              color = Image.GetPixel(i, j); //get 
    }

 }

but im getting a exception

System.ArgumentOutOfRangeException was unhandled
  Message="Parameter must be positive and < Height.\r\nParameter name: y"
  Source="System.Drawing"
  ParamName="y"

I have no clue why im getting this.. im using a BMP with valid heights and same code with hard-coded values working correctly

Just change Height and Width. This is such an example of looking too far in your own code – this brings back so many memories..

for(int i=0;i<BMP.Height;i++)
{
   for(int j=0;j<BMP.Width;j++)
   {
      color = BMP.GetPixel(j,i);    
   }
}
