All, Thanks for you previous help. I've come across another issue. I am compressing a one-band 16-bit image that only has a real image depth of 12 bits. ...
David and Scott, many thanks for your helpful information. I had hoped to use jp2 and not jpx, as I think that standard jp2 clients will miss my xml boxes if...
HI Jason, It seems almost certain that your problem is related to the byte order of the data. Assuming that you are using raw file input to "kdu_compress",...
... If you want JP2 readers to be able to read your files, just write them in a way that is JP2 compatible and list JP2 in the Compatibility List in the File...
Hi All i'm currently working with Kakadu and trying to link the library to Matlab, for we could make some experiments on watermarking and information...
I am not sure what went wrong for you with `Jp2_Family_Tgt', but as far as `Jp2_Colour' goes, what you observe is exactly what should happen. This object is...
Hi Can we get the detailed context information of bit plane coding with the kakadu? I didn't find any applications about that. How to implement that? Any ...
Hi Maggie ! I am not sure if there exists a specific application in kakadu to get the context information but it can be done very easily. You can capture the...
Dr. Taubman, When I read your message, I was pretty sure you had discovered the problem, but after doing some testing I am more confused than before. I am...
Hello I can give you a practical example (lena 512x512 8 bpp) extracted from a study [*] in a european project framework (Migrator2000) DWT : operations/pixel...
Hi, I've got a couple of questions. I'm interested in low memory footprints for a JPIP server. I've determined that an image encoded using an LRCP progression...
When I'm going to use kdu_compress utility to create a jp2 file,I always receive the following words,Kakadu error:Unable to open input image file,"girl.bmp". ...
Hello David, thank you for your hint. I try kdu_v_expand out, and I see kdu_v_expand misinterprets my file too. Data of the original picture size:1920X1080 ...
All, I'm having trouble compressing a fairly large (2GB) 16-bit greyscale file with approximately an 11-bit actual numeric range. The image dimensions are...
... The above text is from message #35 of this discussion group. Do the statements above regarding feasibility of adding hardware accelerators still hold - for...
All, Just wanted to let you know that we've discovered the problem with these images. They are stored as 16-bit, but the actual pixel value range is about...
Dr. Taubman, I believe the discrepancy reported below is in fact a Kakadu bug. It appears that Kakadu illegally uses the label 'mhdr' for the media header box....
Is it related to the current working directory and path to the file? Try typing "dir girl.bmp" at the prompt where you are using this command and see what...
HI Ralf, I have found your problem. One of the four branches in the sample data conversion functions is used to convert from 32-bit floating point data...
My app crashes when I try to establish 2 jpipclient connections from the same app to the same server, with different jp2 files, at the same time. Should this...
Hi Wanjianbang, I have no idea why you cannot open the file. It all works fine for me. The error message is generated only when a call to "fopen" fails, ...
Hi Vikram, There is no substantial difference between v2.2 and the latest versions of Kakadu when it comes to the low level block coding processes. My earlier...
HI Jason, Your problem is most likely that you are using "kdu_stripe_compressor" without incremental flushing. In this case, with your larger image and no...
Hi Roddy, Thanks for spotting this. Actually, Fabrice found a similar thing a month or so ago, when I was too busy to properly read all my email. This typo...
Hi Robert, I cannot immediately think what causes the crash, but it was not something I had tested myself. Can you tell me where it crashes, using a debugger?...
