JPEG 2000 Compression in an SDKWavelet-based JPEG 2000 compression with the quality and expertise of LEAD Technologies

LEADTOOLS JPEG 2000 compression/decompression conforms to the JPEG 2000 International Standard. This new state-of-the-art ISO/ITU still image compression standard provides a fast and flexible solution for high-quality, wavelet-based compression. LEAD has committed to fully support all future parts as they are released and therefore LEADTOOLS JPEG 2000 will continue to grow as the JPEG 2000 standard grows.

Save JPEG 2000 32-bit RGB images with alpha

• Support for lossy JPEG 2000 compression of 32-bit images - the alpha channel can be saved either lossy or lossless. (i.e. the color components of the image can be saved as lossy while the alpha data is saved as lossless.)
• Support for controlling the active bits of the alpha channel has been added to improve the compression.

JPEG 2000 Key Features:

• JPEG 2000 code stream data.
• JP2 file format
• JPEG 2000 Part 2 JPX file format.
  • Save list of bitmaps such as 3D volumetric encoded slices include support for 24 bit RGB and 8, 12-16 bit grayscale ‡ code streams and more.
  • Opacity channels
  • All standard metadata boxes such as XML, digital signature, intelletual property and more
  • Append and extract additional images (frames).
  • Append and extract metadata boxes.
  • Full control of codestreams, frames, metadata.
  • Read and write GML data.
  • Animation support
• Lossless compression, meaning the decompressed image data is exactly as it was before compression.
• Support for four progressive display methods:
  • 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.
• Multiple resolutions can be stored in the same file without duplication of the image data providing the ability to only decode and display the size of image required by the application.
• Error checking and robustness allows the transmission of JPEG 2000 encoded files over a noisy medium. If an error occurs in the decoding, the image will still be displayed.
• Control over the final size of the file without hit and miss quality factor adjustments.
• For the 32 bit image, the alpha can be saved either lossy or lossless. (i.e. the color components of the image can be saved as lossy while the alpha data is saved as lossless.)

JPEG 2000 Overview

JPEG 2000 is a new image encoding standard that provides a feature set vital to many high end and emerging imaging applications. JPEG 2000 provides high compression with image quality superior to all existing standard encoding techniques. This high compression and quality performance is due to the adaptation of wavelet transforms. Wavelet transforms are mathematical formulas that represent complex structures in the image, thereby compressing an extremely large amount of image data into a relatively small amount of compressed data. This compression technique allows applications to save compressed images with higher compression ratios and better image quality as compared to any other software currently in production.

See an example.

JPEG 2000 is a wavelet-based compression stored in a hierarchical format which contains several stored resolutions of the image in the same file without duplication. For that reason, a JPEG 2000 compressed image can then be sent to a device in the resolution that best fits without additional storage overhead. LEAD Technologies has used its more than ten years in the imaging and compression developer toolkit marketplace to formulate a JPEG 2000 product that offers developers the best JPEG 2000 implementation available.
