Remarks

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.

The LEADTOOLS JPEG 2000 Plug in provides support for loading and saving the JPEG 2000 file formats. The JPEG 2000 file formats provide greater flexibility and better image quality, especially at higher compression, than standard JPEG. The greater flexibility includes the ability to control:

• whether or not to transform RGB images to YUV prior to compression
• the type of quantization to use when determining the quantization step size
• the amount of compression
• the size and location of tiles
• the number of resolution levels in the file
• the progression order
• the code block height and width
• whether to use markers to help detect corruption during transmission
• etc.

LEADTOOLS provides the CodecsJpeg2000LoadOptions and CodecsJpeg2000SaveOptions classes for controlling the JPEG 2000 features listed above. To determine or change the current settings for the JPEG 2000 features, use the Jpeg2000 property.

To load JPEG 2000 images progressively, set the Passes property, just as you would for regular JPEG files.

To get the default settings for the JPEG 2000 features, use the Reset and Reset methods.

This support is available only in the LEADTOOLS JPEG 2000 Plug in, and must be unlocked using the Unlock method.
