HI Marc, the non-commercial license is fine. Cheers, david ... From: "marcjacquin" <no_reply@yahoogroups.com> To: <kakadu_jpeg2000@yahoogroups.com> Sent:...
Looks like you should be just replicating the implementation of "kdu_transcode". Should not be overly difficult -- I believe you should find everything...
Hi Amina, There is no explicit information in the codestream about which code-blocks belong to the ROI. However, you can infer which ones involve foreground...
Hi all, I am tryin to reference the kdu_mni.dll in a Web Handler VS 2005 project. I copied the 2 other DLLs (kdu_a/vXX) into the bin directory. But VS at...
Hi all again, I need to open a JPX file, change or add some jpx_metanodes and close it. It seems that I can't use jpx_target::open() with an existing file, ...
We've created a tool using Kakadu that allows users to view high resolution images and then place comments and annotations such as sticky notes, squares,...
Thanks Lars for the input. In fact, I solved it by adding: <hostingEnvironment shadowCopyBinAssemblies="false"/> to the <system.web> section of the web.config...
HI Marc, This is essentially what "kdu_show" does when you add metadata, even though the interface in "kdu_show" is pretty primitive (just for demo purposes)....
The problem you are encountering is that "kdu_show" provides the command-line query as a demonstration only of a "one-shot" request. When the query parameters...
Hi David and all, Many thanks David for this very useful information. Now I can copy JPX infoamtion from jpx_source to jpx_target. But, I still don't ...
Hi Marc, First use `jpx_meta_manager::insert_node' to create a node in the tree which contains all the relevant "asoc", "numlist" and "roi" boxes. Then invoke...
Hi, I am trying to read a JP2 file, extract a region of interest and write the restricted region in a JP2 file. First I read the input JP2 file, then I use the...
I wonder if anyone can confirm if there are any issues with concurrently running multiple Kakadu-based compressors in the same address space. At the moment, I...
HI Christelle, You cannot generally do this by simply writing code-block samples from the input codestream across to the output codestream. The most general...
HI Darren, This is exactly what the "kdu_vex_fast" application in version 6.0 does for decompression. It allows you to create any number of independent ...
Hi David, Thanks. Can you just confirm that v5.2.6 is also good in this respect. v6 looks interesting, but I'll have to convince someone to stump up the cash...
Hi, I'm converting some very long scans into jp2 and I wonder if there are any guidelines for setting optimal parameters for the precinct sizes. In my test...
HI Darren, You can do the same thing with v5.2.6, but v6.0 comes with the "kdu_vex_fast" application which might prove a more useful guide. As for the...
HI Bob, Unfortunately, your image is around the wrong way (very wide, not so high) for incremental flushing to be extremely effective, unless you also choose...
Hi David, Would it be more efficient to compress the image the other way around, and use transcode to rotate it into the desired orientation? Thanks Bob ... ...
We recently recompiled our application to work with the 6.0 dll under XP, which was previously getting about 50% utilization for decompression of 4 streams to...
HI Bob, Yes, that is something I had forgotten to mention. You can also transpose the image implicitly during rendering, rather than having to go through the...
Hi Todd, This is quite a mystery to me. The main things in v6.0 which should affect speed are as follows: 1) v6.0 contains SIMD speedups for 32-bit precision...
Hi David, It's guetting a little messy for me. As I may understand, I must use the Cjpx_meta_manager.insert_node (in C#). I get the codestreams and layers from...
Hi Marc, 1) I agree that the C# binding does not accept an array of regions. Actually, none of the non-native bindings built by "kdu_hyperdoc" allow the...
Hi, I have been creating some multi-channel images which I would like to serve through JPIP. Main idea is that user should be able to select the three channels...
Thanks for reporting this typo. Cheers, David ... From: "jjjuande" <jjjuande@...> To: <kakadu_jpeg2000@yahoogroups.com> Sent: Saturday, October 06, 2007...
