The Bitmap data must be converted into one of the supported datatypes that are derived from MWArray. The first step is to create a native C# double array containing the image data:
//Get image dimensions
int width = bitmap.Width;
int height = bitmap.Height;
//Declare the double array of grayscale values to be read from "bitmap"
double[,] bnew = new double[width, height];
//Loop to read the data from the Bitmap image into the double array
int i, j;
for (i = 0; i < width; i++)
{
for (j = 0; j < height; j++)
{
Color pixelColor = bitmap.GetPixel(i, j);
double b = pixelColor.GetBrightness(); //the Brightness component
//Note that rows in C# correspond to columns in MWarray
bnew.SetValue(b,i, j);
}
}
And pass it into the .NET object after typecasting it to an MWNumericArray:
//Instantiate the .NET object
iprocessclass ip= new iprocessclass();
//typecast the double[] data into a MWNumericArray and pass it into the .NET method
ip.iprocess((MWNumericArray) bnew);
