Jai.widget
Hello,
I just started to use the jai api.
I have a very simple question : since the whole 'widget' sub-package seems to be deprecated, what are the classes that we are supposed to use instead ? I could not find that information in the javadoc.
Thanks in advance
Hi,
since 1.1.2 JAI includes com\sun\media\jai\widget\DisplayJAI.
Regards

How to retain the same resolution while croping a tiff image using jai api
Hi all,
I have designed a program to crop a tiff image.But after croping the tiff,the resultant file resolution is not the same as the original source file.
In the program,the source file Nadeshiko_v1_02.tif has the resolution(X) of 1200 DPI and resolution(Y) has 1200 DPI pixels.
But after croping the resolution of output file is 100 DPI.
Please give me some idea on how to retain the same resolution.

Thanks,

TIFFEncodeParam tep = new TIFFEncodeParam();
// Create {X,Y}Resolution fields.
TIFFField fieldXRes = new TIFFField(0x11A, TIFFField.TIFF_RATIONAL,

Cannot get KeyListener to work with JAI ScrollImagePanel
I am trying to display a TIF image and use the page up and page down keys to show page 1 and page 2 of the image. I started with an example for the JAI documentation.
The problem is that I can't get the key event listener to "see" keystokes.
I think ScrollImagePanel() is doing its own event listening and I don't know how to get at it.
Here is the code:
// http://java.sun.com/products/java-media/jai/forDevelopers/samples/MultiPageRead.java
A single page of a multi-page TIFF file may loaded most easily by using the page
parameter with the "TIFF" operator which is documented in the class comments of
javax.media.jai.operator.TIFFDescriptor. This example shows a
means of loading a single page of a multi-page TIFF file using the ancillary codec
classes directly.

Thanks for any help.
Bill BlalockThanks for exanding your explanation. I am not yet skilled enough in Java to follow you completely but I am getting the idea.
I would appreciate a code snippet using my example so I can better understand. In the mean time I found one way to make it work.
In the example I eventually found that this change ..
show();
panel.requestFocus();enabled the key listener. Bringing the window, even clicking on the panel, didn't give it focus. I understand that the window has to have the focus in order for the key listener to function (different from the mouse listender). I don't understand why the application did not have "focus" even though it was on top and active.
Oh well, lots to learn.
Thanks for your suggestion! -
Hi,
I need to zoom the image during the each button click.I have done 1 program ,but i coulnt able to change the parameter block's value each time.Take this program and just change the pic's path and run

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.

Thankyou
Padma.Are you trying to use the examples (from tutorial etc.)?
If so there are some classes that they use that you have to get the source code to add to your project.
And maybe you need to add the JAI to your JRE (i.e. the one your computer uses when running Java programs as opposed to the one in the JDK).
These are some of the problems I had when I first started using the JAI. -
Hi!
My problem concerns grayscale. First I load tiff-image from a file (OK) and then I want to change its colors to grayscale and after that I save that converted picture as Bmp, but this is not working. I have tried codes that I found from forum, but those arent helping me.So, in brief how to convert tiff image to grayscale image and sav it as Bmp. Could anyone give me a code? This grayscale seems to be problem for many people.You can convert tiff image to grey image by:
public PlanarImage convertColor(PlanarImage src_image){
double[][] matrix = {
{ .114D, 0.587D, 0.299D, 0.0D }
// Create the ParameterBlock.
ParameterBlock pb = new ParameterBlock();
pb.addSource(src_image);
pb.add(matrix);
// Perform the band combine operation.
return (PlanarImage)JAI.create("bandcombine", pb, null);
Write you codes like this:
PlanarImage srcc=convertColor(planarImage);
BMPWriter bmpW=new BMPWriter(srcc,fc.getCurrentDirectory().getPath(),file.getName()); bmpW.saveImage();
Following is class used for save image to bmp

I wanna to use n parts of pictures to be one. When I use png/gif, production picture looks normal. Why I use
jpeg/bmp, my production picture will change any color to red. Please tell me why? The reason is "outImage.setSample"??

Thanks a lot!The samples you are writing into the outImage object may not be compatible with each other, so that is probably why your resulting colors are invalid. You need to add compatible samples. I am assuming this problems stems from the fact that your source data is coming from various image file types, which most likely have different sample/color types among them.

Javax.media.jai not in jmf.jar
Ive download JMF 2.1.1e from
http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/download.html
and installed it. However it does not seem to contain the javax.media.jai or com.sun.media.jai packages as per the documentation :-
http://java.sun.com/products/java-media/jai/forDevelopers/jai-apidocs/index.html
I checked the contains of the jmf.tar and and the other jars that came with the download
eg the following can not be found
import javax.media.jai.widget.ScrollingImagePanel;
import javax.media.jai.NullOpImage;
import javax.media.jai.OpImage;
import com.sun.media.jai.codec.SeekableStream;

import com.sun.media.jai.codec.TIFFDecodeParam;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageCodec;
So have I done something wrong, is this code no long in the jmf.jar, or is the documentation wrong ?Thanks, that got me the jai_imageio.jar , however this jar does not contain the any of the following packages
import javax.media.jai.widget.ScrollingImagePanel;
import javax.media.jai.NullOpImage;
import javax.media.jai.OpImage;
import com.sun.media.jai.codec.SeekableStream;

import com.sun.media.jai.codec.TIFFDecodeParam;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageCodec;
are they in another jar that I have not included, or do I need to get them from somewhere else? -
Hi,
Say A.tiff contains 6 pages and B.tiff contains 5 pages. I need to 5 pages of B.tiff into A.tiff, so that A.tiff contains 11 pages. Can someone pls show me the fastest way of acheiving this ?
Currently I am using ImageDecoder to decode A and B to put all the contents of 11 pages into vector, then use ImageEncoder to encode them as new image say C.tiff. This method is very slow. I hope someone can advise.
Regards,
Kok.When I try this program proposed by JAI, the C.tiff only contains 2 pages in C.tiff, 1 from A.tiff and the other one from B.tiff. Where went wrong ?

Multiple SQL Update within Parent Query
I am tring to extract an image from within a MS SQL image field,
opening the image using JAI, getting the src.getWidth() & src.getHeight
() of each item within the database, and then writing the width and
height back into the database. Everything works except when I goto
write the values into the database - the page (when loading) continues
to work and work and work until I restart the tomcat service. I do not
understand why this would occur, and what is even stranger - I have
very similar code i used for resizing images in the database into a
thumbnail - display and original file sizes using a similar approach...
and that works with out a problem...
I have tried the code with out the inner update query - it works. I
tried with just the selection of a single specific item in the first
query and that works, but when I try multiple updates the second query
appears to stall.

jaggayyaChanging the fonts in Print using ABAP is not possible. as basic report output is a text editor.
By changing "Customizing of Local Layout" will only change in display screen and not in print.
One possible way to create a new printer formatr thry SPAD and use that format in while printing.
to know more details about SPAD
Using SPAD - SAP Spool Administration to print different paper size
The SAP spool system manages its own output devices. This includes mostly printers, but also fax and archiving devices. In order for you to use output devices defined in your operating system from the SAP System, you must define these devices in the SAP spool system.
Print to a dot matrix printer using computer paper with 66 lines

Hi there,
I'm facing lot of problem while loading large image (25+ MB JPG/TIFF) in editor pane using ImageIO. I always get OuofMemory exception or my machine (p4 2.4ghz/512 ddr) get hangs. Is there any way to load large images within a moment in Java? I have seen one s/w (written in vc++) that do the same. I'm trying to replicate that s/w.
Is there any 3rd party Java API to do the same? Have you guys develop similar s/w before?
I've tried many ways: by changing heap size, using ImageMagick, spliting the image, etc. but never get satisfactory results.
Any help would be appreciated.
Thanks in advance.
-tamalYou can use Java Advanced Image
http://java.sun.com/products/java-media/jai/downloads/download-1_1_2.html
this will avoid the out of memory error.
I use it to read and show 20K*20K pixel images.
the loading is immadiate.
If you use javax.media.jai.widget.ScrollingImagePanel (deprecated) class to visulize the image is quite quick.
Obviouse that if you want to visualize the entire image you will need to wait an approprite time for rescaling it. -
I am trying to view Tiff file, but the problem that it is not clear view
I mean it is very bad look, not like view it in another Tiff viewer.
and also it is too big, I mean the width and hight.
any way, this is my code:-
public void ReadingTiffFile()
String strFileName = "d:\\b.tif";
File file = new File(strFileName);
SeekableStream s = null;
try
s = new FileSeekableStream(file);
TIFFDecodeParam param = new TIFFDecodeParam();
ImageDecoder dec = ImageCodec.createImageDecoder("tiff", s, param);
RenderedImage img = dec.decodeAsRenderedImage(0);
JFrame frm = new JFrame();
frm.getContentPane().add(new PnlTiffGraphicsView(img));
catch (IOException ex1)
System.out.println("Error While Rending Images");
public class PnlTiffGraphicsView extends JPanel
RenderedImage img = null;
public PnlTiffGraphicsView(RenderedImage img1)
img = img1;
public synchronized void paintComponent(Graphics g)
gg.drawRenderedImage(img, new AffineTransform());
Many thanks in Advanced.I found this code somewhere online... I took a few snippets from it to form my own methods that accepted image paths... Hope it helps.
