HI Jan and others, A number of you have been reporting related problems with "kdu_server" freezing over HTTP links. I have now found the source of the problem...
I am looking through the "JPEG 2000 Part I Final Committee Draft Version 1.0" (http://www.jpeg.org/public/fcd15444-1.pdf) and have noticed the following on...
HI Karthik, Sorry for the late reply. The concern you have is that lossless compression using the MCT produces slightly larger files than slice-by-slice...
Hi, I had the same problem with num_threads option. I have some machines in my project (one dual-core and other multiprocessor with 4 processors). The command...
Dear Kakadu users, I have just found a minor bug in the Kakadu core system which had caused problems sometimes with images containing entirely empty...
HI Mike, You are absolutely right. Thanks for this. Cheers, David ... From: "mikeunverferth" <no_reply@yahoogroups.com> To: <kakadu_jpeg2000@yahoogroups.com> ...
Greetings, I am conducting an experiment for a project and I have a question pertaining to output file size of a KDU compressed image. Please bear with me...
Dear Kakadu team, In using kdu_region_compositor I have found the need to initialise a buffer's surface with my own 32 bit value of 0x00000000. This allows me...
I don't think it is appropriate to change the definition of the core library function just to correct an error in the usage within an application. Also, as...
I have now been able to reproduce this type of problem. I believe it only occurs when incremental flushing is used together with multiple threading, because ...
I don't believe this problem is related to having multiple tiles, as the crash occurred for me with an untiled image also. Message 4207 (text follows)...
Yes there is no problem for "KduRender.java", I apologize. But your fix for "KduRender2.java" is incomplete. Changing the `new_offset' value does not affect...
Yes, you are correct. Cheers, David ... From: "jpafpaf" <no_reply@yahoogroups.com> To: <kakadu_jpeg2000@yahoogroups.com> Sent: Friday, September 08, 2006 11:46...
Hi Mike, I have taken your suggestion for v5.2.2 and also found the bugs related to multi-threaded processing with incremental flushing. I will release an...
Hi Kevin, I'm not sure if the "3-4 times as long" observation can be explained. However, I have not observed such a problem so far with the code I have...
I am attempting to write a method that dynamically determines what compression paramters to use given a set of constraints on my system. I am using ROI...
Good Morning DR Taubman, I am vamsi kadiyala a graduate student from Oklahoma State University. Presently we are working on the Region Of Interest for gray...
Hello, I'd like encode some yuv files using kdu_compress. I guess I must first split my input YUV file into 3 .raw files before running kdu_compress, (right?) ...
Downgrading to KDU 5.1 to 4.2 solved the problem where KDU never completes and uses all CPU. I guess it is a threading issue. Does 5.2 fix this? - Derek...
Hi, I am stuck on a strange problem. My software works well in rendering a new JPX file through JPIP, and the client cache is successfully filled (thanks to...
HI Derek, I have no idea what could cause "kdu_compress" not to complete, but this sounds like a possible bug in multi-threading. I suggest first trying it on...
You should not need to downgrade. Worst case, you can specify "-num_threads 0". But try using version 5.2.2. Also, if the problem still exists, what I need...
If kdu_compress seems to be in an infinite loop while compressing RAW images, this might be the same case as an earlier bug in v5.1, for which you could find a...
