 Description  « Hide
Sculptie fans are going to hate me for this one .

The encodeImpl() for OpenJPEG currently assigns tcp_numlayers to 1 (through a convoluted parameters.tcp_numlayers++ and tcp_rates[0] to 0 and leaves it at that. This creates a single layer, lossless JPEG2000 file for every image uploaded. The attached patch changes it to create the same number of layers as files created by Kakadu-4.2.1 with close approximations of equivalent compression levels for each layer.

Even better than this would be changing encodeImpl() to add a lossless mode, and adding the lossless support to Kakadu as well but this is all I can do without having access to the KDU code.
