Stream PNG
Dalam Asp.Net, kita bisa mengirim image lewat Response.OutputStream.
Untuk kasus PNG agak sedikit berbeda, karena kita perlu membuat stream yang 'seekable'.
Dibawah code yang bisa lebih menerangkan.
//newBitmap is variable of your Bitmap object.
//Save to File
newBitmap.Save(@"c:\test.png", ImageFormat.Png);
//Save to Stream Jpeg or Gif
//but not for png
newBitmap.Save(Response.OutputStream,ImageFormat.Jpeg);
//Save to Stream Png
MemoryStream mStream = new MemoryStream();
newBitmap.Save(mStream, ImageFormat.Png);
Response.ClearContent();
Response.ContentType = "image/png";
Response.BinaryWrite(mStream.ToArray());
Response.End();
