Using MODI and changing image to grayscale

Question

I'm using Microsoft Office Document Imaging (MODI) and am trying to load a TIF file, but convert it to grayscale before performing the OCR.

I'm not sure on how to do this.

I have this in my code:

private MODI.Document _MODIDocument = null;

_MODIDocument = new MODI.Document();

_MODIDocument.Create(filename); axMiDocView1.Document = _MODIDocument;

Can someone tell me how to convert the image portion of the document to grayscale?

Thanks

Change technologies. We went that route, ran into version issues with Office, encountered corrupt files on network drives, and then MS discontinued it with Office 2010. — TrueWill, Jul 21 '11 at 21:04

public static Bitmap Grayscale(Bitmap bitmap)
{
    //Declare myBitmap as a new Bitmap with the same Width & Height
    Bitmap myBitmap = new Bitmap(bitmap.Width, bitmap.Height);

    for (int i = 0; i < bitmap.Width; i++)
    {
        for (int x = 0; x < bitmap.Height; x++)
        {
            //Get the Pixel 
            Color BitmapColor = bitmap.GetPixel(i, x);
            //I want to come back here at some point and understand, then change, the constants
            //Declare grayScale as the Grayscale Pixel
            int grayScale = (int)((BitmapColor.R * 0.3) + (BitmapColor.G * 0.59) + (BitmapColor.B * 0.11));

            //Declare myColor as a Grayscale Color
            Color myColor = Color.FromArgb(grayScale, grayScale, grayScale);

            //Set the Grayscale Pixel
            myBitmap.SetPixel(i, x, myColor);
        }
    }
    return myBitmap;
}

Click event under

Bitmap oldBitmap = new Bitmap(Server.MapPath("~/Db/Plates/" + dosyaadi), false);
Bitmap newBitmap = Grayscale(new Bitmap(oldBitmap));
string name = "grayscale";
newBitmap.Save(Server.MapPath("~/Db/Plates/") + name + ".jpg", ImageFormat.Jpeg);

then delete org pic..
