Hello, I haven't done this by myself yet byt I guess you should try using kdu_compress with "-jp2_alpha" argument. There is something about that in usage...
So I've noticed the following behavior with kdu_region_compositor, which seems to be contrary to the documentation. Lets say I do the following: kdu_dims dims;...
Dear Prof.Taubman According to your suggestion, I have tried to compress some volumetric data and the results are pretty good. The results of lossless coding...
This is what the -jp2_alpha switch produces: Kakadu Error: The `-jp2_alpha' argument must not be used unless there is at least one spare image component to use...
Hi all, I'm busy writing the second version of a jp2000 viewer application. Now, I'm getting some rather odd errors, stranger still because kakadu seems to...
(new to Kakadu) Hi all, I'm trying to grab a realtime video from a camera, run the video thru a MJPEG2000 codec and distribute the compressed video with...
Hi, After compression, how can I determine the total size of the compressed data that has been written to the kdu_compressed_target? I'm not writing to a file,...
I presume you have created a class derived from kdu_compressed_target to actually implement the ability to write to your memory buffer. In the derived write()...
For your question 1, The sample kdu_v_compress provides simple file reading capabilities as a demonstration. In your own application, you would replace the...
In your original posting, you labeled the components as "RGBN". What does the "N" represent? If it is near-infrared (as is created by QuickBird and Ikonos...
hello, I work with the KakaduSoftware and i like to create a video which follow the CINEMA2K and CINEMA4K profiles. But I not found any documentation of these...
Dear Kakadu users, I know that there are a number of minor issues that require my attention and have been the subject of recent emails. I have been run off my...
I would like to get ahold of the WIN32 executables for version 4.5. I didn't see an archive list on the Kakadu website. Let me know if you know where I can get...
Hi, I appear to be having this problem in Kakdu 4.5. Has anyone determined a solution? -scott ... recently? I tried to setup a simple delegation, however the...
Is there a reason why kdu_show stops when an image has multiple tiles with no information? When i tried to open an image consisting of 2 tiles, each with a ...
Right, that makes sense. I just wasn't sure if I could rely on that. Does the writing process ever jump around, or does it basically write from start to...
Hi, If the images are not differential signal of YCbCr (with alpha included in the differential) then try and split the data into a component basis and...
Hi, David. I just started looking into upgrading from Kakadu 4.5.2 to 5.1, and I'm having a major problem with the server crashing. I run kdu_server with its...
Is it possible to drop, say 90% of a tile's information, adjust the tile (SIZ) header and to open it with kdu_show without using the resilient mode. Or are...
Within the kd_http_transmitter.service_queue() method, there are places where it tries to write to the channel, but fails. Your comments state that the reason...
Hi, I am analysing the JPIP streams by hand to understand the spec with reference to kdu_server, and to see how to create other servers. I would be grateful...
Nothing is wrong, and there is no padding. The JPEG2000 Signature Box is always first, and always 12 bytes. Those bytes are Length = 12 (decimal) Type =...
... The file type box will NOT always be 20 bytes. That compatibility list field really is a list; one 4-byte/character code for each define "reader" that is...
... Thanks for all the help, I was working with the JPIP spec and Kakadu, I will have to buy the book :-) A case of RTFM for me. Many thanks, Norman...
Hi, just a short question: I use kdu_compress for parallel (reversible) encoding of YUV420 Raw data in 16 bit precision... kdu_compress -i test_Y.raw,...
Hello, I'm a French engineer working on a project linked to jpeg2000 compression. I've downloaded win32 and linux executables in order to perform some tests ...
Hello! I use JPEG2000 to compress data which may not have a certain absolute pixel error after compression (e.g. 100 in a 12 bit grayscale picture). Until now...
