Support streaming (file larger than memory size) in opj_decompress #122

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Now that the library supports large files decompression, it would be nice to 
make j2k_to_image support large JP2 files (> 2Go).

Only formats with Large File Support would be concerned (AFAIK, only TIFF, once 
libtiff 4.0 is included in 3rd parties).

Should be classified as enhancement, not defect, but i don't know how to do it

I am pretty sure we can close this one. Feel free to reopen if you believe 
openjpeg 2.0.0 did not adress this issue.

I am pretty sure this is NOT fixed, just looking at the code :
http://code.google.com/p/openjpeg/source/browse/trunk/src/bin/jp2/opj_decompress
.c#900
The image is fully decoded in memory there.

This issue is not about libopenjp2 to support streaming, but about 
opj_(de)compress to support streaming.
Those 2 codecs should ideally allow TIF<->JP2 conversion for arbitrary sized 
files.

Sorry misread the description, thought this was about LFS in openjpeg. 
re-opened.
