JAI problem

Hi all,
I have small problem. In my application I'm using JAI package (imported). When I run my app in Eclipse, everything works perfectly. But when I compile this app to JAR file (Export to JAR), I have error in console as follows:
java.lang.NoClassDefFoundError: com/sun/media/jai/codec/SeekableStream bla bla bla...
follows by definition of error position and so on...
Why this error does not ocure in Eclipse?
Other task:
I have imported JAI classes into build path. Later I uninstal JAI package and install it back into different location, imported in buildpath new versions, but Eclispe is still looking for the old ones. I'm getting message :
"Class E:/JAVA/jai/lib/jai_codec.jar which is referenced by the classpath, does not exist"
even if the newly imported .jar faile has other location path.
Anybody can help?

because eclipse builds a classpath for the application and adds the JAI jar to it. When you run the exported jar, the JAI jar most likely is not there, or it is not in the location that java expects it to be. Open the exported jar and find the META-INF/manifest.mf file - check the class-path line; does it contain the jai jar?

JAI - problem displaying additional pages from multi-page image

Hi,
I have 10 page multipage tiff images. And i would like to show the images one-by-one on a ScrollingImagePanel.
I have a Main frame with two panels. Panel1 which shows the ScrollingImagePanel.
And Panel2 has two buttons. LOAD Button show the 1st page on the ScrollingImagePanel.
And NEXT button is suppose to show the 2nd page and continue until the end of the multipage images.
I am having problem with the NEXT button. I wrote a program that show the page number and page height
on the output screen. It shows the page# and different heights. But it would not show the images on the ScrollingImagePanel.
It just shows the 1st page. I would appreciate if you can help me out with this problom.
Please find the code which is written in JBuilder.

Archivelog files and Rman backup

Hi all,
Please somebody guide me regarding the following concept.
We have the oracle server version 10.2.0.1.0, working with Windows OS,
I had set the parameter log_archive_dest_1 for locating archivelog files, then I had changed the archivelog files to the flash recovery area(located in another disk) by using the parameters db_recovery_file_dest_size and db_recovery_file_dest.
Now the archivelog files are being located at two different location. At this point, If I take backup for archivelog files with the aid of RMAN, then ,
How will the RMAN take backup from those two different locations?
Thanks&Regards,
Jai.

PROBLEM :
I have archivelogs duplexed - when running RMAN - rman backups up the archivelogs from both duplexed destinations - from the user manual - this should not be the case, any ideas?
Details:
I have archivelogs duplexed
I have the following set in rman :
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 2 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/backup/rman/WPPMD/control_%F';
CONFIGURE DEVICE TYPE 'SBT_TAPE' PARALLELISM 10 BACKUP TYPE TO BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/backup/rman/WPPMD/backup_%d_%T_%U' MAXPIECESIZE 10 G;
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE COMPRESSION ALGORITHM 'LOW' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE;
CONFIGURE ARCHIVELOG DELETION POLICY TO BACKED UP 1 TIMES TO DISK;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/app/oracle/product/11.2.0/dbhome_1/dbs/snapcf_WPPMD.f'; # default
When I run backups via a script :
backup incremental level=$RMAN_LEVEL database plus archivelog;
($RMAN_LEVEL changes between 0 and 1 depending on the day of the week)
It backs both duplex copies of the same archivelog
From the document :
Oracle10g / 11g - Getting Started with Recovery Manager (RMAN) [ID 360416.1]
It says :
Even if your redo logs are being archived to multiple destinations and you use RMAN to back up archived redo logs,
RMAN selects only one copy of the archived redo log file to include in the backup set. (Since logs with the same log sequence number are identical, there is no need to include more than one copy.)
But this is not the case ie
RMAN> list archivelog sequence 2445;
using target database control file instead of recovery catalog
List of Archived Log Copies for database with db_unique_name WPPMD
=====================================================================
Key Thrd Seq S Low Time
4640 1 2445 A 17-DEC-10
Name: /log/recovery_area/WPPMD/archivelog2/1_2445_735315419.dbf
4639 1 2445 A 17-DEC-10
Name: /log/recovery_area/WPPMD/archivelog/2010_12_17/o1_mf_1_2445_6jpx9n7c_.arc
So it still backing up both copies of the archive log.
Any ideas? is this a bug?
Thanks
Luca

Blur video frame with NI PCI-1411 and JAI CV M-300 camera (urgent problem)

Hello,
I am new with Vision and I need some advice with a problem, which I encountered.
I have a computer with integrated NI PCI-1411 board, which is connected to a JAI CV M-300 camera. I am measuring a steel part which is positioned in a dark chamber. The part is put on a glass board and is illuminated from underneath with light.
The part is moving. I have to measure this part when it reaches the camera region. I have made a test with not-moving part and everything is perfect. Now, when I move the part I get blur frames from video (with these no part measurement is possible). I need specify, that the camera has no trigger, so it makes video all the time (this video is later inspecting with Vision Builder).
I have tried to change parameters in MAX, but no involvement. I have found no proper icd/file for the camera.
I also could use a SONY DXC-950P camera, if this is better.
How can I eliminate the blur from video frames? Or what am I doing wrong? Is the camera not good enough? Camera + trigger would get better images.
I have attached the video frame with moving object (static) and the blur video frame with moving object (dynamic).
Please give me a answer or ideas as soon as possible.
Thanks.

You are using an interlaced camera. It takes half the picture (every other line), waits a split second, then takes the other half of the picture (the other lines). When it puts the two images together, you can see the two positions it was in when the images were taken.
The best solution is to use a non-interlaced or progressive scan camera, which takes the entire image at one time. The Sony might be this type of camera, since it has a P in its name. I didn't look up the specs.
If you can't get the right kind of camera, your only other option is to use fields instead of frames. One field is the half image taken at one time. The image will be half the height of the original image, though, which can mess things up.
Another possibility is the reduce the resolution of the image. If you take every other pixel in both directions, you will have a very clear image that is half the size of the original. You can do this with Extract in LabVIEW, not sure if it is available in VBAI.

Image border problem using JAI

I've written some very simple code to scale an image down to a small
thumbnail in JPG format but the quality is quite horrible. Is there a way of making it look nicer?
src = JAI.create("fileload","filepath")
ParameterBlock params = new ParameterBlock();
params.addSource(src);
params.add(xScale);//x scale factor
params.add(yScale);//y scale factor
params.add(0.0F);//x translate
params.add(0.0F);//y translate
params.add(Interpolation.getInstance(Interpolation.INTERP_NEAREST));
dest = JAI.create("scale", params,null);
I switched to InterpolationBicubic, instead of Interpolationnearest the quality was much better but the resulting image contained borders.
could some one tell me is there any other way to get better and nicer results.

Yes you can fix the border problem by setting a render hint to change the way the borders are handled. Something like the following will do the trick.
You can also use BORDER_WRAP instead of BORDER_COPY, both seem to have a similar result. Mind you I am still very dissapointed with the quality of the bicubic resampling in JAI, but at least this will fix the problem with the borders.
RenderingHints rh = new RenderingHints(JAI.KEY_BORDER_EXTENDER, BorderExtender.createInstance(BorderExtender.BORDER_COPY));
dest = JAI.create("scale", params,rh);

I am not saying it will work, but I would ask if you tried "Dilate"? I don't know what the parameters are supposed to be for the different methods, but I do know how to get a listing of them. See the code below:
 OperationRegistry ory = JAI.getDefaultInstance().getOperationRegistry();
 String [] temp = ory.getRegistryModes();
 String []temp2;
 for (int which = 0; which < temp.length; which++) {
 temp2 = ory.getDescriptorNames(temp[which]);
 System.out.println("\t"+temp[which]+":");
 for (int cual = 0; cual < temp2.length; cual++) {
 System.out.println("\t\t"+temp2[cual]);
That will get you a listing of all of the registry modes and the descriptor names within each mode. For parameters and explanations, well, I guess check out the source code for the JAI library and then rifle through it until you find an example, or use trial-and-error, since the only documentation seems to refer to deprecated calls (as I have noted in the most recent version of JAI).

Problem while loading a JApplet ( which uses JAI ) on Netscape across ssl

Hi Folks...
I m having some problem in applet.. can any1 of u guys help me???? My problem is as follows..
I m having 2 JApplets (Swing applet) one of the applet is using JAI (Java Advance Imaging APIs). I m trying 2 load both the applets in IE as well as in Netscape across SSL (ie thru https protocol) .Both the applet can be loaded on IE across SSL. but when i m trying to load the applet on Netscape, one of the applet which is using JAI is not getting loaded across SSL. The other applet which is not using JAI is running fine across SSL on Netscape also.
I m getting some exception.. Is this exception comming bcoz JAI is not compatible with Netscape r bcoz of somethinf else??? If it is bcoz of the fact that Netscape does'nt have any support for JAI across SSL. then watz the possible solution 4 that. How can i overcome by this problem. Its very urgent.. i need to do it any how... Plz plz help me out if u guys have any idea abt this.. any help is most welcome..

Exactly what exception are you getting? That will really help in determining the problem. Also, do you have the same problems when going over a regular connection (i.e. not over SSL)?

Problem to find the javax.media.jai package

hi everyone!! it's not the first time I ask this question, but i have troubles to find javax.media.jai..
I've downloaded the jai 1.1 and everything is fine... However, I have to use classes from the javax.media.jai... I made the import, and it doesn't find it, as if it doesn't exist... Someone tells me that the jai contained it, so why doesn't it find it??
i'm using a java version 1.2.. do you think that is the problem?
thanks a lot, and sorry for my bad english!!
Anne.

thanks a lot!!! it helps me but doesn't resolve my problem!! ;o)
you may be right,, it's a classpath problem. well i work under unix, so i have to give my classpath by the command setenv CLASSPATH ...
i didn't find the jai_core.jar in my JAI 1.1, I have only the BugFixes.jar...
I tried to download the latest version of JAI, and unfortunately i have a new problem with the .tar, i don't manage to "open" it... the command
tar xvf [archieve file] gives me some errors!!
so I don't know what I'm gonna do.... I think I'm going to ask someone to send me the package, or the specific classes I need, it would be more easier!!
Thanks
Anne.

Problem with continuous scale, crop JAI operations

Hi,
I am using JAI in my application, i need to do the following operations in order, for the given image.
1. Scale
2. Crop
3. Crop
Each operation gets the RenderdOp object given by the previous operation as input [Output of the 1st operation is provided as input to the 2nd, etc.]
I am facing a problem while doing the 3rd operation. This crop gives an IllegalArgumentException : Crop The rectangular crop area must not be outside the image.
When i debug the program i found that minX and minY values are causing the problem. Input for the third operation is a 45x46 image and the crop is for 45x45 and the minY is 10, the crop recatangle is 0,0 to 45,45 the crop considers the minX and minY as the starting positions of the image and result the exception.
Can anybody guide me to solve this problem!
- Rakesh

Very late, but I've just faced the same problem today. Since I'm in a hurry I've not been able to research if that behaviour is OK or some kind of bug. I guess it's OK but are missing something...
Anyway, I just summed the values from getMinX () and getMinY () to the x and y variables which I passed to the Crop operator. That way it's like if I were working in the 0,0 coordinate which I expected to be.

JAI + JAI Image IO - ImageWrite operation problem: color reversed

I installed jai 1.1.3 and jai imageio 1.1 on jdk 1.6 and did a test with the following code.
     public static void main(String args[]) {
          Byte[] bandValues = new Byte[3];
          bandValues[0] = (byte)255;
          bandValues[1] = (byte)0;
          bandValues[2] = (byte)0;
          ParameterBlock params = new ParameterBlock();
          params.add((float)300).add((float)200);
          params.add(bandValues);
          PlanarImage bim = JAI.create("constant", params);
          JAI.create("imagewrite", bim, "d:/dev/baseImage.png", "PNG");
          JAI.create("filestore", bim, "d:/dev/baseImage2.png", "PNG");
          PlanarImage pi = JAI.create("imageread", "d:/dev/baseImage.png");
          PlanarImage pi2 = JAI.create("imageread", "d:/dev/baseImage2.png");
          JFrame frame = new JFrame();
          frame.setTitle("Output Image");
          Container contentPane = frame.getContentPane();
          contentPane.setLayout(new GridLayout(1,3));
          contentPane.add(new JScrollPane(new DisplayJAI(bim)));
          contentPane.add(new JScrollPane(new DisplayJAI(pi)));
          contentPane.add(new JScrollPane(new DisplayJAI(pi2)));
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.setSize(960, 400);
          frame.setVisible(true);
     }I found that the color in the output file created by "imagewrite" was reversed - bim is red but pi is blue.
The one created by "filestore" was correct: pi2 was red.
Did I use the "imagewrite" operation incorrectly? How should I use the imagewrite operation?

I think you are using it correctly and you've encountered a bug. The same thing occurs on my machine. PlanarImage is using an interlaced raster which stores pixels as BGRBGRBGR ect... But the only way I can see this causing a problem is if the imagewrite operation was going directly to the DataBuffer for the pixels. If it retrieved it through the raster the colors should not be switched.
Interestingly enough if I do this
JAI.create("imagewrite", bim.getAsBufferedImage(), "d:/dev/baseImage.png", "PNG");then it works correctly. This suggests even more that the fault is with imagewrite operation interpreting the PlanarImage wrongly.

Jai som.vistech compilation problem

Hello!
The problem is that when I try to import a class from com.vistech, I get a "packave com.vistech.jai.imageio does not exist".
The strange thing is that I can import classes form com.sun and javax.media so I suppose the installation has been made ok.
What could be the problem?
Please help!!!

is the package is pre defined in java? ( I Think that package is not a predefined package from java. It is user defined pacakage). If not u have to set classpath to that package first and then u have to compile.
since com.sun and javax.media are predefined they will be automatically added to classpath but user defined packages will not be added.

JAI TIFF - JPEG colour problem

Hi all...
I want to use JAI to convert from TIFF to JPEG. Here is my test program:
import javax.media.jai.JAI;
import javax.media.jai.RenderedOp;
import java.awt.image.renderable.ParameterBlock;
public class Test {
     public static void main( String[] args ) {
          String srcFile = args[0];
          String dstFile = args[1];
          RenderedOp op = JAI.create( "fileload", srcFile );
          ParameterBlock p = new ParameterBlock()
                    .addSource( op )
                    .add( dstFile )
                    .add( "JPEG" );
          RenderedOp saveOp = JAI.create( "filestore", p );
}It works fine, except the colours in the output are all wrong.
After running
java Test NEC_LCD3000+Soundb_R.tif bad.jpg
my output looks like
http://xtuml.jdns.org/bad.jpg (if you can even see it. Firefox refuses to display the image. Gimp and KView can open it though, but all the colours are messed up)
The output should look like
http://xtuml.jdns.org/good.jpg
The original was ripped from NEC's website:
http://www.nec-display-solutions.com/coremedia/download/18634/LCD3000-ProductPicture-Soundbar-Side-R-TIF.zip
I suspect it's a problem to do with Color Models or something, but I'm way out of my depth in this area.
Can anybody suggest a solution?
Thanks in advance!
Regards,
James

Maybe this is the problem... the original image has an alpha channel. When I used the GIMP to flatten it back to RGB (with no alpha channel), JAI works fine...
Does JAI support RGBA? Am I posting in the wrong forum? Is the whole world against me? :P

[JAI] Palette problem

Hello,
I want to have a image with a palette looking like :
0->255 Red
256->512 Green
512->768 Blue
How can I do that with JAI ?

the problem is how you want to treat to border of your image. The blur works by calculating the average value of the neighbouring pixels for a given center pixel. So you have to tell your algorithm what to do if your "center" pixel sits on the outside border and lacks its neighbours...
take a look at the docu on java.awt.image.ConvolveOp which specifies two types of "edge_conditions", i.e. solutions to the problem: EDGE_NO_OP, EDGE_ZERO_FILL

Problem with JAI instruction

the line code is
input = JAI.create("fileload",file);
when i compile my project there is no problem but when i run it i have this error
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at algorithms.fuzzycmeans.FuzzyCMeansImageClusteringApp.main(FuzzyCMeansImageClusteringApcan you telle me what is the problem

Thanks both for answering!!!
yes I agree with The fiscal periods could be different systems, but documents were created as PRD case, same month and year.
where could I check "Fiscal Year variant" ( If you are not talking about program variant ).
Guys, I was debugging and I check that exactly on GET BKPF ( is like a loop ) for my document 1600003538 bkpf-monat = 03, but suddenly in GET instruction with another document 1700003522 bkpf-monat = 01
and this is the value printed
document = 1600003538 .
monat = 01 ( must be monat = 03).
I really appreciate your answer, thanks.
