• Now start your Visual Studio, and create/open a .NET imaging project.
• Click on "Add Reference..." and then browse to add the Yiigo.Image.dll in the unzipped download file to your project reference.
• You will need to create an instance of stream source by passing a stream object to its constructor, and then assign it to the source property.
• Below is the namespace and sample code to generate images from stream in Visual C#. Feel free to copy to your project for an evaluation.
• You can add more codings in the end for more image manipulation such as resizing, converting, and annotating.

using System.IO;
using System.Drawing.Printing;
using Yiigo.Imaging;
using Yiigo.Imaging.Processing;

//Creates an instance of BmpOptions and set its various properties
Yiigo.Imaging.ImageOptions.BmpOptions ImageOptions = new Yiigo.Imaging.ImageOptions.BmpOptions();
ImageOptions.BitsPerPixel = 24;


//Create an instance of System.IO.Stream
System.IO.Stream stream = new System.IO.FileStream(@"C:\sample.bmp", System.IO.FileMode.Create);


//Define the source property for the instance of BmpOptions
//Second boolean parameter determines if the Stream is disposed once get out of scope
ImageOptions.Source = new Yiigo.Imaging.Sources.StreamSource(stream, true);


//Creates an instance of Image and call Create method by passing the BmpOptions object
using (Yiigo.Imaging.Image image = Yiigo.Imaging.Image.Create(ImageOptions, 500, 500))
{
      //You can do some image processing if necessary
