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...
Hi David, Sorry to bother you again with this. OK I have to be more accurate. In the C# insert_node call, should I pass null instead of a Cjpx_roi or should...
Hi Ambarish, Yes, 1 bit/pixel means 1 bit per RGB pixel. It would be safe to make Qstep 16 times smaller than the default value. Cheers, David ... From:...
Hi Jukka, Firstly, let me say that the JPX file format is ideal for what you want to do. I have no idea whether free viewers support it properly (probably...
Hi, I'm a student and for my thesis I'm developing a software to transmit radar images in real time over internet. The radar images I'm handling are aquired in...
Hello David Taubman, I'm a student of the "Universidad de Almerķa". (Spain, Europe) I know Kakadu is not mainly intended to be used in C# and JAVA, but for...
In Kakadu version 6.0, there is a class "kdu_compressed_target_nonnative" which derives from "kdu_compressed_target" and can be properly inherited by C#/Java...
Thank you very much. I got confused because of: http://tech.groups.yahoo.com/group/kakadu_jpeg2000/message/4919 [C# buffer compress / decompress] Now its ok! I...
Hi David, I've been playing with the "simple_example_c" (ported to c#), but I saw that compressor.push_stripe(buffer,stripe_heights); consumes a lot of time. ...
Hello, I am looking into licensing the Kakadu SDK. This would be for the company that I work for, however, we will be using the SDK for internal purposes only....
Hi, I want to modify the lifting analysis algorithm of kakadu, but I am not able to find the code. Please, can you tell me where is this code? Thanks...
Dr. Taubman (or anybody), How is the speed pack stuff distributed to the integrators? Is it also source code? I've been emailing this question (and evaluation...
Hi David If I input a RGB (4:4:4) image into the kakadu engine, will it encode it as RGB or will in first convert the input RGB image into YCbCr and then...
I get it! (My YUV 4:2:0 raw file is 8 unsigned bytes per component value.) Just setting this properties: // Construct code-stream object siz_params siz; ...
C++ bool push_stripe( kdu_byte * stripe_bufs[], ... C# bool push_stripe( byte[] buffer, ... ... stripe_bufs[] [kdu_byte *] Array with one entry for each image...
Hi, if You want combine in C# some kind of tables (in example bytes) You may use Generic List as follow: using System.Collections.Generic; List<byte[]> buffer...
Thank you very much for writting a reply, but that list can't be used as "byte[]" parameter. (Because List<byte[]> isn't a byte[]) It seems that c# bindings...
You should consider using the second form of the `push_stripe' function for non-native language bindings like Java and C#. That form allows the image or a...
