You may also create the image dynamically using the functionality provided by the Graphics.FromImage function. In the following example the image is created on the fly and passed to the NImageFillStyle constructor:

// create objects
Bitmap bitmap = new Bitmap(256, 256, PixelFormat.Format32bppArgb);
Graphics graphics = Graphics.FromImage(bitmap);
Pen pen = new Pen(Color.Black, 1);

graphics.Clear(Color.White);
graphics.DrawRectangle(pen, 10, 10, 236, 236);

// dispose objects
pen.Dispose();
graphics.Dispose();

someObject.FillStyle = new NImageFillStyle(bitmap);

' create objects
Dim bitmap As New Bitmap(256, 256, PixelFormat.Format32bppArgb)
Dim graphics As Graphics = graphics.FromImage(bitmap)
Dim pen As New Pen(Color.Black, 1)

Graphics.Clear(Color.White)
graphics.DrawRectangle(pen, 10, 10, 236, 236)

' dispose objects
pen.Dispose()
graphics.Dispose()

someObject.FillStyle = New NImageFillStyle(bitmap)

Another useful feature of the image fill style is that it can also modify the alpha channel of the image:

someObject.FillStyle = new NImageFillStyle("c:\\images\\myimage.png", 125);

someObject.FillStyle = new NImageFillStyle("c:\\images\\myimage.png", 125);

The above code will apply a semi transparent raster filling on the object based on the raster image contained in the myimage.png.
