Re: [gdal-dev] Extracting Jpeg2000 image from nitf file

I don't know how to do that without significant code. What you can do, given the right gdal build, is to extract the image and recompress it as JPEG 2000. That would have the advantage of working with just about any NITF compression method, not just C8/M8. Obviously that does involve more CPU and

The problem below is nothing to do with GDAL, you just need to initialise the variable (probably by some kind of command line argument - argv[1] if nothing else). If that doesn't make sense, is there another programming language that you are more comfortable with? Brad -Original

Even, It is not my compression, and although it isn't formalised yet, I think its probably too late to change. I'll take it back to the NTB in any case. The specific case is for "good enough" compression of floating point data without (further) loss. Thanks for the CPLZLibDeflate() helper

[gdal-dev] RasterIO support for zlib / deflate compression?

I've been looking at how much work it might take to implement a new NITF compression value (IC=CC and IC=MC) which is basically just ZLIB DEFLATE encoded blocks. I'm mostly following the pattern used for JPEG, and its down to the part where I just need to do the compression: int
