JPEG2000: Overview

In This Topic

JPEG 2000 is an image compression for color and grayscale images and

it is suitable for both lossless and lossy compression.
JPEG2000 compression compresses color and grayscale image more effectively than JPEG compression.

VintaSoft JPEG2000 .NET Plug-in has a set of classes for easy manipulation with JPEG2000 images.

JPEG2000File class

Jpeg2000File class allows to:

open an existing JPEG2000 file from disk or stream
get access to the JPEG2000 page - Jpeg2000File.Page
save changes in Jpeg2000 file - ImageFileBase.SaveChanges
save Jpeg2000 file to another file or stream - ImageFileBase.Save
pack Jpeg2000 file to another file or stream - ImageFileBase.Pack

Here is C#/VB.NET code that shows how to load an existing Jpeg2000 file:

Vintasoft.Imaging.Codecs.ImageFiles.Jpeg2000.Jpeg2000File jpeg2kFile = 
    new Vintasoft.Imaging.Codecs.ImageFiles.Jpeg2000.Jpeg2000File("image.jp2");

VB.NET

Dim jpeg2kFile As New Vintasoft.Imaging.Codecs.ImageFiles.Jpeg2000.Jpeg2000File("image.jp2")

Jpeg2000Page class

Jpeg2000Page class allows to:

get information about image of Jpeg2000 page - Jpeg2000Page.Width, Jpeg2000Page.Height, Jpeg2000Page.BitsPerPixel, Jpeg2000Page.Resolution, Jpeg2000Page.Palette, Jpeg2000Page.ColorSpace
get image of Jpeg2000 page - ImagePage.GetImage
get part of image or scaled image of Jpeg2000 page - Jpeg2000Page.GetTileImage, Jpeg2000Page.GetTileRectImage
set tile of image of Jpeg2000 page - Jpeg2000Page.SetTileImage
get metadata of JPEG2000 page - Jpeg2000Page.GetComments
save image of Jpeg2000 page to file or stream - Jpeg2000Page.Save

Here is C#/VB.NET code that shows how to get the page of Jpeg2000 file as VintasoftImage object:

Vintasoft.Imaging.Codecs.ImageFiles.Jpeg2000.Jpeg2000File jpeg2kFile = 
    new Vintasoft.Imaging.Codecs.ImageFiles.Jpeg2000.Jpeg2000File("image.jp2");
Vintasoft.Imaging.VintasoftImage pageImage = jpeg2kFile.Page.GetImage();

VB.NET

Dim jpeg2kFile As New Vintasoft.Imaging.Codecs.ImageFiles.Jpeg2000.Jpeg2000File("image.jp2")
Dim pageImage As Vintasoft.Imaging.VintasoftImage = jpeg2kFile.Page.GetImage()
