LEAD CMW Compression in an SDK learn the advantages of LEADTOOLS proprietary wavelet format

LEAD CMW compression/decompression outperforms all other known image compression algorithms in quality and compression ratio. In other words, if you need the best quality images while using the least amount of disk space, then LEAD CMW is just what you need.

CMW Overview

CMW is an advanced wavelet compression that outperforms JPEG2000 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.

And, just like with JPEG2000, 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.

Key features that make CMW better than JPEG2000

• CMW files are smaller than JPEG2000 files of comparable visual quality
• CMW files can be loaded and saved faster than comparable JPEG2000 files

LEAD's CMW format uses Wavelet CMP compression. Full 24-bit color images and 8, 12 and 16-bit grayscale images are supported.
