I'm trying to uncompress a JP2 file that's fully in memory. This is a test bench: std::ifstream file; file.open(argv[1], std::ios::binary); //open a JP2 file ...
I have a set of files with multiple jp2 images in them, and I need to use the lib to unpack an image from where the file pointer is, from a file (or stream)...
If your language of choice is C/C++, then you can implement a file reader class that derives from 'kdu_compressed_target' to fit your specific needs. _____ ...
Does it really crash, or does it give an error message? If it really crashes, where does it crash (using a debugger)? Have you verified that your image file...
Hi all ! I used and modify the kdu_compress sample to generate a jpeg 2000 frame in 422. I can get the total size of the generated data using the function ...
Ah, that's good. So I guess it was a compilation problem -- otherwise it did not seem to make any sense. Cheers, David ... From: "gizwiz68" <yahoo@...> ...
Actually, there is no direct function that gives you this information. It would be possible to collect this information along the way, during compression, but...

Hi all ! I am using kdu_compress to encode file to yuv 422 jpeg2000 frames. Most of the encoded frames can be decoded by the adv 202 except a few of them... ...
Hello Thomas, The ADV202 will not robustly handle a 1920x1080 tile size (non- interlaced). It does not have sufficient internal memory to handle an image of...
Dear All We are compressing the image using KDU_COMPRESSION. Whether it compressing the images as lossless or lossy compression or kindly guide us if any...
Save the file as a raw codestream. You are creating raw codestreams using simple_example_c, not JP2 files. A JP2 file contains a raw codestream, embedded ...
Hi Michael, Obviously you want to modify "kdu_vex_fast". You will note that the `vex_frame_queue' object is initialized with an MJ2 video track object, from...
Hi Michael, Why do you think those statements can be removed from the source? Some boxes have 16-byte headers, with 64-bit box length attributes. Maybe not in...
hi,professor david, I want to set the arguments of simple_example_c in VC6.0. For example, I have written "lena.pnm lena.jp2" in "project-setting-debug- ...
You need to specify in the project settings "-i lena.pnm -o lena.jp2"; from your example, you are missing the "-i" and "-o" arguments (for input and output). ...
