Thanks David, It's exactly what I want. I do some tests with the weigths of CSF and I want to see the difference between the images. Cheers, Olivier ... The...
I have been working on a version using wxWindows; but it's subject to extensive delay as I do not have to have it at present. I'd estimate completion around...
Thanks Dr. Taubman !! I got that that working by iterating over all precintcts and accumulating packet_samples .. Although it might be more useful for Kakadu...
Hi David, So right now I have modified the kdu_compress example to have n number of threads individually flushing out a row of tiles (at the moment it uses a...
I use a serie of commands as follows to merge lot of tiles in a huge jp2. (Windows, v4.5 tools, NTFS) kdu_compress -i in.tif -o out.jp2 -frag 4,8,1,1...
Well, I've compressed an image of 2.8GB and have never run into a problem. We use the following options: kdu_compress -i in.bmp -o out.jp2 Clayers=10 -rate...
Hi, First, 2GB seems not to be any limit for kdu_compress. I have created without any problem a 4.1GB compressed file (100 fragments, Windows XP Pro, NTFS file...
I think you're right! Now I know it should work, I will check my Windows / hardware / drivers. Problem should be there. The only difference between your sample...
Hello, Using slopes is simple. First just compress an image with suitable -rate argument. When ready, kdu_compress returns on the screen something like: Layer...
Hi folks, I'm still having a bit of problem using kdu_client in my java application. It seems to crash when I request an image that isn't there from the...
Sorry for the delay in responding to this message. If you have not already solved your problem, I believe that you almost certainly have an overwrite problem. ...
Hi Ronan, There are two possible causes for your problem that I can imagine: 1) You may be working with an older version, which reached a 2 GByte limit if you...
Hi Ronan, You can find quite a lot of past messages which discuss the use of the "-slope" parameter in the archives of this email discussion group. There is a...
Hi David, Currently, I don't have TLM marker being generated and I have reverted back to a single thread version but retained using multiple codestream objects...
Hello, I'm trying to build a simple viewer through a jpip connection, and I'm missing something to make work the connection, and I don't know what. The client...
Hi again :-) It was told me in private that the steps for a synchronous jpip connection are : 1) wait for main header received 2) jpip_client.post_window() 3)...
Hi, If I have a jp2 image that has 1 quality layer, what processing is involved in adding quality layers ( with specified bit-rates ) and how fast/slow might...
Hello Dr. Taubman, Another simple question and hoping that solution would be simple too. I am transfering just j2c codestream over JPIP. If I have to transfer ...
Hi Steve, Adding layers after the image has been compressed is not easy. Content providers are strongly encouraged to provide a large number of layers in...
Hi Saurabh, JPIP does not really support the transfer of metadata other than metadata which can be defined within one of the box-based file formats defined for...
Hi again again ;-) I'm still stuck with a simple JPIP problem, so I will try to better explain my situation, hoping someone could help me. I'm trying to get...
Hello, I want to expand my own class from the abstract class "kdu_output". While compiling Java wants to call a constructor of "kdu_output". But the...
I can only help you with the 2 part .. To get the dimensions you need to create a codestream object with the source as kdu_client.. Then all the access...
Thanks Dr. Taubman for the quick reply.. The idea of encapsulation in JP2/JPX has struck me before too but I wanted to work with j2c streams beacuse of their...
HI Arvin, No problem at all with 16-bit images -- even much higher bit-depth. The demonstration applications "kdu_compress" and "kdu_buffered_compress"...
Professor Taubman has advised me that the Kakadu Software does not read nor write GeoTIFF and GeoJPEG2000 images, and he asked me to post a public message...
The server is designed to support all the JPIP syntax for interchange purposes, whereas the client does not necessarily use all possible requests. The ROI...
Actually, you could not create an instance of `kdu_output' in C++ either, since it contains a pure virtual function. Only derived objects which define the...
HI Mehdi, The key thing to keep in mind is that the server returns the minimal amount of information to satisfy your requests. If you open a raw codestream, it...
