HI Darren, The VIX format is described in the usage statement produced by "kdu_v_compress". It is a dead simple format, unlike AVI, so to convert AVI to VIX...

Hi Yun Yaw, For general purpose CPU's there is not generally any speed advantage in going from floating point to 32-bit integer fixed point representations,...
Hello. I'm getting familiar JPEG2000. I'm trying to find where can I reference the computational cost of each block of JPEG2000. It would be all right, if it...

... Hi, one possible approach might be to encode the source file with shrinking precinct sizes for every decomposition level starting in spatial domain. Thus,...
Hello, I'm new to JPEG2000 and Kakadu. While studying the kdu_expand sample application, I find that it's possible to pass the -region command line option...

Hi all, did any one ported the kdu_server to Linux? Can any one poit out the problems of doing this, if any? Some tips about how to do it would be nice also. ...
Hi, I'm working with a lossless compression of 12-bit images. I some cases, I only need an 8-bit representation of the data. I found out that there isn't any...
Hi MIke, What you ask is simple to do with the source code -- a minor change in "kdu_expand", but "kdu_expand" does not provide a command line option to do it...
The kakadu library won't compile under vc8 (beta). Here are the reported errors: kdu_client.cpp kdu_client.cpp(690) : error C2664: 'kd_parse_request_field' :...

Hello David, Thanks for your reply. Can you point me to the area where I'd make the change? I'm new to Kakadu and am a bit overwhelmed by the rich set of...
We have ported Kakadu 4.1.0 to SUN Solaris Workshop 6.2 and to COMPAQ TRUE64 UNIX and are planning on porting it to SGI IRIX. We are also interested in...
My input images are almost always tiled (typically 1024 x 1024) and I want to spread the work out among 2 to 8 CPUs. Specifically, where in the code do I give...

Jim, have you also ported the kdu_Server as well? Best regards, CARLOS SERRÃO (ISCTE lecturer, Adetti VP, PhD student) DCTI- IS/IT Department Adetti/ISCTE -...
I'll leave a Kakadu expert to discuss the rendering problems, but I'll comment on the UnkC field. The value of the UnkC field should not affect the display or ...
Can anyone tell me what the eighth byte in the JPIP HTTP-TCP chunk header is used for by the Kakadu JPIP server? Sometimes there is non-zero values in there,...
HI Jim, I believe that this has been done. Basically, if you take a look at "kdu_compress", you will notice that it keeps multiple tiles active at once (where...
HI Darren, Good question. I took a look and it turns out that I just forgot to set that byte, so it remained uninitialized in the server -- anything could...
Scott is right, the UnkC byte is not the source of trouble. Kakadu's demo apps always set it, since they do not trust the user, but an application built on...
