This article will explain in detail how to use the. net image compression library. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

When the quality of the picture is not very important, the size of the picture plays a very practical role in the application of the system or network transmission.

NQuant. Net is an open source .net color conversion library that uses optimized algorithms to compress images and output high-quality 8-bit PNG images with 256colors.

In general, the same size of the picture, the more bits of the picture, the larger the size of the picture, nQuant. Net through the optimization algorithm, the picture can be converted to 8 bits, can make the size of the picture compressed a lot.

The source code of the class library and a sample shell program can be downloaded from the website: https://archive.codeplex.com/?p=nquant

Where core is the class library code and shell is a console sample program.

In the. Net program, add nQuant.Core reference, through the following simple code, you can achieve image compression.

Var quantizer = new WuQuantizer ()

/ / sourcepath is the image source path using (var bitmap = new Bitmap (sourcePath)) {

/ / targetpath is the destination path using (var quantized = quantizer.QuantizeImage (bitmap, alphaTransparency, alphaFader)) {quantized.Save (targetPath, ImageFormat.Png);}}

In the shell program, you can test the picture in cmd, nQuant.exe the full path of the picture, you can complete the compression of the picture.

The size of the compressed image changes as follows:
