Incremental (progressive) load (ideally with computation carry through)

[Steve Williams]

Hi all,

Just dropped latest from trunk into our stuff. Wanting to get progressive load working as a file downloads. Is there an example of how to do this somewhere please or do we just decompress as normal with whatever data we have thus far & the decoder does the best job it has with what it's got.

Wanting something a little more advanced than that if possible so any computation from previous incremental that's useful for the next can be carried through rather than starting a fresh (next partial) decompress from scratch.

Hope that makes sense - thanks for the great work.

Seems even basic partial decode has regressed.

Just got our progressive download working ... would be awesome to be able to connect it to openjpeg ... when it can decode partial streams :)

use opj_decoder_set_strict_mode(codec, FALSE)

Thank you, Even :)

Will give that a try later today.

Works - sincere thanks :) Update to our 3D web browser featuring progressive j2k download/visualize shortly.
