+== Description ==
 The jp2 files used by the Secondlife client, are actually j2k files. These can be encoded by image_to_j2k from openjpeg. The script identifies the image-resolution, and converts the image to a valid SL-resolution/aspect ratio. Subsequently it checks for jpg-files, and converts them to valid openjpeg input files if necessary. Valid openjpeg files are then converted to j2k fileformat, by image_to_j2k. At last the j2k file is renamed to jp2, and can be used as an secondlife texture. Use genassets.pl to generate an asset-set out of these files.
