Hi Mathieu, It is fine to use "kdr_region_decompressor" even if you do not need fully incremental decoding. It does not create any significant inefficiencies....
hi, all I have just finished one JPEG2000 encoder software,but I compressed the image very bad, I can't find where are the bugs,please help me to analyze it? I...
Hi, In general, is is hard to look at an image an identify exactly what is causing error. You could also have more than one error. Saturation/Round-off errors...

I tested the sample application and noticed that the output from the decompression engine generates 24 bit depth image formats. Is it possible for the kakadu...
Hi Ambarish Natu: Thanks for your matlab code, I have used it in my code , but I got the image like in the attachment, This a black and white image, But there...
Hi All, Happy new year to all of you JPEG2000/Kakadu folks out there! In this early moment of the year I am having a doubt about the rendering of image...

Hi Jason, Kakadu will not do colour quantization for you. If the image already was compressed in a palettized form, the palette will be preserved, but this is...
Hi Fred, Your supposed policy for determining actual dimensions is the one implemented by "kdr_region_decompressor" in the Kakadu toolset. However, that does...

It appears that newer versions of g++ solve whatever caused the problem. If anyone else encounters the same problem, use a newer g++ version. Thanks, Dave...
Hi Benoit, First, you should be aware that the code-stream colour transform will not be used if the components have different dimensions (as per the standard),...
Does anyone out there build kakadu with the Intel C++ Compiler? If so, can you post your make files and share what code changes (if any) were needed? I don't...
Hi David, your fast and detailed answer is very helpful like lot of things in this forum. What I would like to do with JPEG 2000 is in fact a good component ...
David, Is there any way to pass a single input filename and a single output filename (.raw) to kdu_expand and get back all the raw component layers in the...
