JPEG 2000

Here is a detailed VB.NET sample for encoding and decoding images with RasterEdge .NET Imaging SDK and JPEG 2000 Codec. (For C#.NET developers, please go to JPEG 2000 Codec for C#.NET. Want to view Image and document in Winforms or Web applications, please go to JPEG 2000 Codec in Winforms and Web Document Image JPEG 2000 Codec.)

Start Visual Studio .NET (2005 or later version);
Begin a new project with programming language - VB.NET;
Add RasterEdge.DotNetImaging.dll & RasterEdge.DotNetImaging.Jpeg2000.dll to your VB.NET applications;
Add the appropriate Imports directive:

Imports System.IO
Imports RasterEdge.Imaging
Imports RasterEdge.Imaging.Processing
Imports RasterEdge.Imaging.Jpeg2000

Create an JPEG 2000

Create JPEG 2000 images with following VB.NET codes:

Dim jp2 As Jp2Decoder = New Jp2Decoder()
RegisteredDecoders.Decoders.Add(jp2)

Getting Image Information

If you want to know the image information, copy following VB.NET codes:

Dim info As Jp2ImageInfo = CType(RegisteredDecoders.GetImageInfo("myimage.jp2"), _
Jp2ImageInfo)
Console.WriteLine(info.FileFormat)

Reset JPEG 2000 Decoder

Developer may reset JPEG 2000 decoder with following VB.NET codes:

Dim jpeg As JpegDecoder =
CType(RegisteredDecoders.GetDecoderFromType(typeof(JpegDecoder)), JpegDecoder);
jpeg.ScaleFactor = JpegScaleFactor.Half
