Hi, I am currently working on an extended kdu_show application and I noticed that kdu_show only support rotation by 90º increments and vertical/horizontal...
HI Jason, I think you are confused. 24 bits/pixel means (almost invariaby) 8 bits/sample with 3 components (usually red, green, blue). For this case, you...
Hi John, All exceptions that are expected to be caught by an application should be of integer type. Generally, these exceptions are thrown by your own error ...
Hi John, I have tried doing something similar using the "kdu_stripe_decompressor" demo application and it works perfectly for me. I suspect that your problem...
Hi Mike, I am just about to send you a version 5.2.3, which contains very few changes from 5.2.2, but does include a fix that should allow you to freely use...
Hi John, What happened here depends on the coordinates you used. The relevant coordinates are "Sorigin", "Stile_origin" "Ssize" and "Stiles". If you don't...
What is the proper way to compress these multiframe images so that they may be decompressed on a client machine in a progressive fashion? Currently, I compress...
HI Jason, There is no one right way to compress multi-frame imagery. What you are doing is fine. It is even possible to use multi-component transforms when...
As for your machines, I am not sure that an AMD processor with lower clock rate should be slower than a Celeron with higher clock rate. The actual speed...
It is more efficient to use the RCT or YCbCr transforms than to compress the R, G and B components entirely independently. However, independent compression...
HI Willem, First, to keep memory consumption low, you need to be sure that all precincts have corresponding pointers, using the "ORGgen_plt" option during...
Hi guys! This forum is a really good source for anyone dealing with J2k issues. I love it! I have a question regarding the extended jp2 format JPX. Is is ...
... Hi, it's my understanding that you can create mj2 files by merging jpx files using kdu_merge. According to the usage examples file: kdu_merge -i...
Has anyone been able to successfuly compile x64 Kakadu using Visual Studio 2005 and would you be willing to share your .sln files? I am getting a number of...
I am trying to implement a start/suspend/restart functionality in the decompression of 10 layer 16bit grayscale images. Basically, is it possible to decompress...
Hi folks, David T, et al., I was looking through the documentation, to try and see if we could save some decompress and buffer copy / convert time for...
Hi David, Thanks for your responses. There were some problems posting, I had mixed some things up and didn't write very clearly. I'm gonna write a couple of...
If I receiving a raw codestream (that I want to interactively decompress) using kdu_cache, how can I determine the offsets for the `KDU_MAIN_HEADER_DATABIN',...
Hi all I am interested in compressing volumetric data using kakadu. I want to compress 32 frames of 512x512 16 bit images. I went through all the available...
Hello everyone: I want to divide the JPEG 2000 code stream into SMALL pieces according to their location and resolution level, so that they¡¦re suitable for...
David, Can you compress three display components (e.g., R,G,B) then add components, compressing them one at a time, to the same compressed image so that the...
HI Tim, I finally have a Studio 2005 edition and will ensure that future releases also include the build environments for .NET 2005, in addition to VC6 and...
Hi Jason, These data-bins have meaning all by themselves, in an absolute sense, independent of any specific location within a physical codestream. I am not...
Hi Joakim, Generally speaking, JPX compositing rules are not compatible with MJ2 compositing rules, so you could not generally convert a JPX animation to a ...
Hi Rob, Your are right that the precise path does not use SSE. Indeed it doesn't really use MMX either, except to compensate for insufficient registers on...
Hi John, You can do this. Since it is not a common application, there is no demonstration app which exactly does it. However, the key to doing everything you...
David, There is a small bug in kd_tcp_transmitter::configure_flow_control() (in delivery.cpp). The parameter names used in the code (and the member variables)...
I'm obviously doing something illegal. I have a 3-component image, 25,600 pixels wide and 25,600 pixels high that I'm compressing using the stripe compressor....
Hi all, I am implementing Multi Component Transformation defined in JPEG-2000 image coding System extensions. I own a copy of Kakadu V5.0 with *non-commercial...
