LEADTOOLS CMW Image Compression SDK

CMW Image Compression

Overview of LEADTOOLS CMW Image Compression SDK Technology

CMW is an advanced wavelet compression that outperforms JPEG 2000 in quality, speed and compression ratios. LEAD CMW includes support for multiple resolutions making your applications faster and more memory efficient because the entire file does not have to be loaded and decompressed just to load a low resolution version of a high resolution image.

  • Compress and decompress color and grayscale CMW image data including 12 and 16 bit grayscale
  • Lossy and lossless compression options
  • CMW image compression technology available as C DLL, C++ classes, .NET classes, WinRT Libraries, iOS, OS X, Android, Linux, WIC codecs, WF activities and Web services.
  • Add CMW image compression to single and multi-threaded applications
  • Native 32 and 64 bit binaries for CMW image compression

And, just like with JPEG 2000, you have the ability to specify a progression order, giving you control over the display effect during a progressive decompression. The available progression orders are:

  • Quality Axis - The image starts blurred and the sharpness increases as more image data is received.
  • Resolution Axis - The image is loaded as a smaller version and the physical pixel size increases as more image data is received.
  • Color Axis - The image is loaded one color plane at a time. The image starts loading as a grayscale image and the color will fill in as more image data is received.
  • Position Axis - The image is loaded as blocks. As more image data is received, more blocks are displayed.

Additionally, you have complete control of the resulting file size and quality. You can choose to compress a file based on any of the following:

  • Target file size
  • Compression ratio
  • Quality factor

You can even specify lossless compression so that when the compressed image is decompressed it will be exactly the same as the original image.

Why CMW is Better than JPEG 2000

  • CMW files are smaller than JPEG 2000 files of comparable visual quality
  • CMW files can be loaded and saved faster than comparable JPEG 2000 files
