C# Raster - Image Compression in C#.NET

Overview

All RasterEdge engineers and programmers are committed to developing and perfecting documents and images encoding and decoding toolkits in long term. This page is designed to show the general guide on how to compress and decompress images and documents in multiple C#.NET programs. You may have heard of image lossy and lossless compression, and we will give more info on them at the bottom of the tutorial page. create barcode image using c#, asp.net print pdf without preview, add image to pdf itextsharp vb.net, extract images from pdf c#, vb.net extract text from pdf, c# data matrix reader. Our C#.NET Imaging Compressing SDK ensures users with huge abilities to read and write images in lossy or lossless compression model in C# applications.

Supported Compression Methods

The compression methods be supported by XImage.Raster are as follows: vb net pdf create thumbnail from image, c# itextsharp pdfcontentbyte add image, how to crop a pdf in c#, c# pdf embed font, vb.net print form to pdf, how to open pdf file using c#, convert pdf to html vb.net.

Bzip

     The RasterImage will use the Burrows-Wheeler algorithm, Named Bzip2 yet.

DXT1

     It is also known as Block Compression1 or BC1.

DXT3

     It is collectively also known as Block Compression 2 or BC2 converts 16 input pixels(corresponding to a 4*4 pixel block) into 128 bits of output. asp net replace text fro pdf free, asp.net pdf writer, preview pdf in asp.net, display pdf in iframe mvc, asp.net pdf viewer control, c# asp.net open word document, asp.net tiff image viewer.

DXT5

     It is collectively also known as Block Compression 3 or BC3 converts 16 input pixels into 128 bits of output.

Fax

Group4

     It is known as CCITT Group4 fax compression.

JPEG

JPEG2000

LosslessJPEG

     It is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data

LZW

     It is lempel, Ziv, Welch compression algorithm.

RLE

     It is run length encoding.

Zip

     It is an archive file format that supports lossless data compression.

ZipS

Piz

Pxr24

     The PXR24 compression scheme used in Industrial Light & Magic's Open EXR file format is based on Carpenter's work.

B44

     B44 This form of compression is lossy for half data and stores 32bit data uncompressed.

B44A

     An extension to B44 where areas of flat color are further compressed. Regular B44 compresses uniformly regardless of image content.

LZMA

     An algorithm used to perform lossless data compression.

JBIG1

     A lossless image compression standard from the Joint Bi-level Image Experts Group.

JBIG2

     An image compression standard for bi-level images, developed by the Joint Bi-level Image Experts Group.

Undefined

     It is not support compression.

No

     It represents no compression.

Image Compression In C#.NET

Sample code compression image with fax compression format:

            RasterImage image = new RasterImage(@"F:\input.tif");
            ImageProcess process = new ImageProcess(image);
            process.TransformCompression(Compression.Fax);
            image.Save(@"F:\Test.tif");

Sample code compression image without compression format:

            RasterImage image = new RasterImage(@"F:\input.tif");
            ImageProcess process = new ImageProcess(image);
            process.TransformCompression(Compression.No);
            image.Save(@"F:\Test.tif");
