CMW Image Compression SDK Libraries

LEADTOOLS libraries for .NET (C#, VB, Core, Xamarin, UWP), C, C++, iOS, macOS, Linux, Java, and web developers support CMW compressed image data. CMW is a wavelet compression, like JPEG 2000, that outperforms JPEG 2000 in quality, speed, and compression ratios. CMW supports multiple resolutions, so applications do not have to load and decompress an image that is too large for the requirements.

Feature-rich CMW Image Compression SDK

CMW Image Compression Libraries

LEADTOOLS libraries can load and save lossy and lossless grayscale and color CMW-compressed image data in CMW and TIFF formats, and memory streams. CMW compression features options to control the file size and image quality when saving, including properties to set the target file size, compression ratio, or quality factor. Designed to store multiple resolutions in the same file, CMW compression provides an efficient means to store image data that needs to be rendered to devices with vastly different screen sizes or mediums.

Control display effects during decompression

Progressive Decompression

LEADTOOLS CMW libraries support progression order to control 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.
CMW versus JPEG 2000

Why CMW is Better than JPEG 2000

Image data that has been compressed with CMW compression exhibit comparable visual quality and smaller file sizes when compared the the same image data compressed with JPEG 2000. Additionally, CMW-compressed data can be compressed and decompressed faster then JPEG 2000.
