Overview of LEADTOOLS JPEG 2000 Image Compression SDK Technology
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.
Add JPEG 2000 image compression to single and multi-threaded applications
Native 32 and 64 bit binaries for JPEG 2000 image compression
Compress and decompress color and grayscale JPEG 2000 image data including 12 and 16 bit grayscale
Lossy and lossless compression options
Alpha channel of 32 bit images can be compressed separately from the image data either lossy or lossless
Control the active bits of the alpha channel to improve the compression
JPEG 2000 code stream data
JP2 file format
JPEG 2000 Part 2 or JPX file format
Save list of images such as 3D volumetric encoded slices including support for 24 bit RGB and 8, 12-16 bit grayscale code streams
Opacity channels
All standard metadata boxes such as XML, digital signature, intellectual property
Append and extract additional images or frames
Append and extract metadata boxes
Full control of codestreams, frames, metadata
Read and write GML data
Animation support
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.
