c# drawing text using custom pixels

Question

I\'m wondering if that\'s possible: I got a c# application with something like a display consisting of about 11000 circles drawn on the Form.

What I want to achieve

You could write on an invisible BitMap with the DrawText method and then scan the bitmap's pixels and turn the corresponding circles on.

Did that last week with the cells of DataGridView. Real easy.

Here is some code:

    public void drawText(string text, Font drawFont)
    {
        Bitmap bmp = new Bitmap(canvasWidth, canvasHeight);
        Graphics G = Graphics.FromImage(bmp);
        SolidBrush brush = new SolidBrush(paintColor);
        Point point = new Point( yourOriginX, yourOriginY );

        G.DrawString(text, drawFont, brush, point);

        for (int x = 0; x < canvasWidth; x++)
            for (int y = 0; y < canvasHeight; y++)
            {
                Color pix = bmp.GetPixel(x, y);
                    setCell(x, y, pix);     //< -- set your custom pixels here!
            }
        bmp.Dispose();
        brush.Dispose();
        G.Dispose();
    }

Edit: You would use your dimensions and your origin for the DrawString, of course
