JPEG 2000

[leo]

A JPEG 2000 plugin based on J2K-Codec is now available.

The new plugin improves on the old JP2Raw plugin's JPEG 2000 handling in several ways:

• Much faster at viewing files.
• Much, much faster at generating thumbnails.
• Support for x64 (64-bit Windows).
• Support for alpha channels (transparency).
• Support for less common .J2C & .J2K code-stream data files.
• Support for Unicode filepaths.
• Support for Opus's USB-Mode.
• Doesn't call abort() on decode errors. (An aspect of JasPer which I dislike even more than its speed.)

The new plugin continues support for:

• 8bpp images.
• 16bpp images.
• Color (RGB) images.
• Greyscale images.
• .JP2 format files.

This plugin is included with Opus from version 9.1.2.0 onwards.
