Saving a Gif image using JAI (Java Advanced Imaging)

I'm trying to read in and save out a bunch of gif images in JAI. I'm reading them in, resizing them, and then saving them back out, all in gif format.
For some reason some of my gif images work fine, and some don't throw any errors, but save as 0k size.
When I do img.getColorModel().toString(); I get the following output for images that do work:
IndexColorModel: #pixelBits = 8 numComponents = 3 color space = java.awt.color.ICC_ColorSpace@1bbf1ca transparency = 1 transIndex = -1 has alpha = false isAlphaPre = false
And the following output for images that don't work:
ColorModel: #pixelBits = 24 numComponents = 3 color space = java.awt.color.ICC_ColorSpace@1bbf1ca transparency = 1 has alpha = false isAlphaPre = false
If I try to save the images that don't work out as jpg's they work fine, but if I try to save them out as gif's, I get 0k files.
Any insight on how to correct this problem?
I assume it has something to do with the 24 numComponents in the non-working gifs, but I'm really not sure.
Please help.
Thanks.

Can you post your image property?
Try using this for image compression:
int pixelSize = img.getColorModel().getPixelSize();
if (1 == pixelSize) {
tiffEncodeParam.setCompression(TIFFEncodeParam.COMPRESSION_GROUP3_2D);
} else if (8 == pixelSize) {
tiffEncodeParam.setCompression(TIFFEncodeParam.COMPRESSION_DEFLATE);
} else if (24 == pixelSize) {
tiffEncodeParam.setCompression(TIFFEncodeParam.COMPRESSION_JPEG_TTN2);
Thanks,

JAI (Java Advanced Imaging) and CF8

Hi
I'm using the Java Advanced Imaging API since CF6 and made
several jar files to manipulate images (as it wasn't integrated in
CF).
Today I installed CF8, put the "jai_core.jar" and
"jai_codec.jar" in the "cfroot\runtime\jre\lib\ext" folder as I did
when I first developped my application or when I migrated from CF6
to CF7 but today it does not work.
I have the following error (see attached), ImageInfo and
GetTaille are my own jar classe and method.
I saw that there is already a "jai_core.jar/jai_codec.jar" in
"cfroot\lib" So I think that there is a conflict between the two
JAI's. I removed mine, but I have another error : "An exception
occurred when instantiating a Java object. The class must not be an
interface or an abstract class. Error:
com/sun/media/jai/codec/ImageEncodeParam."
I also tried to replace the JAI of CF8 by mine (just for a
test) but I have the same error.
Do you have any idea of a solution ?
I know I can now use the CF8 tags to manipulate images, but I
have to rewrite lots of code and I think there is still
manipulations that CF8 can't handle (CMYK images, ICC profiles,
Thanks in advance for your suggestions

> "An exception occurred when instantiating a Java object.

I don't know how you're using
com/sun/media/jai/codec/ImageEncodeParam in your code but the error
is clear. ImageEncodeParam is an interface in the CF8
jai_codec.jar. You can instantiate a concrete class, but not an
interface. Possibly the private classes have changed since you
first wrote the jar?
> I think that there is a conflict between the two JAI's.

You could be right. If the jars are sealed having two of them
in the classpath might cause that kind of error.

JAI(Java Advanced Imaging) Problem with splitting TIFF images

Hi
I am getting problem with height when I use this program to split TIFF images
ImageDecoder decImage = ImageCodec.createImageDecoder("tiff", inStr,
null);
Then it creates RenderedImage page by page and encodes them to file:
String outFileName = "";
OutputStream outStr;
TIFFEncodeParam encParam = new TIFFEncodeParam();
encParam.setCompression(TIFFEncodeParam.COMPRESSION_PACKBITS);
for (int i=0,n=this.getPageCount(); i < n; i++)
outImage = this.decImage.decodeAsRenderedImage(i);
outFileName = "C:\\Temp\\Split" + i + ".tif";
outStr = new FileOutputStream(outFileName);
BufferedOutputStream bOutStr = new BufferedOutputStream(outStr);
encImage = ImageCodec.createImageEncoder("tiff",bOutStr,encParam);
encImage.encode(outImage);
bOutStr.flush();
bOutStr.close();
}The images are shrinking when I split . I need a solution to this problem.
Thanks for any help in advance
Sudheer.

Hi
Did you get a solution for your problem. I am also trying to split a TIFF file.

Finding a Gif Encoder for Java Advanced Imaging (JAI)

I'm trying to find the GIF encoder for Java Advanced Imaging. I keep reading all over the place that there is one, but for the life of me I can't figure out where it is supposed to be. Could anyone please enlighten me?
Thanks

After I installed this, it still doesn't report gif as a possible encoding type:
String[] codecs = ImageCodec.getEncoderNames(img, null);
            for (int j = 0; j < codecs.length; j++) {
                String codec = codecs[j];
                System.out.println (codec);
            }only reports the following types available:
pnm
jpeg
tiff
png
bmp

How to set color space to JPEG image with Java advance Imaging

How to set color space to JPEG image with Java advance Imaging.
is there any API in JAI which support to set color space.

I'm definately no guru, but this is how you can change it.
CTRL + ALT + Click on the part of the component that you want to change. This brings up the Hidden Dom Inspector, background of component will be surrounded with a red outline (Make sure the red outline is surrounding the part of the tabset you want to change), Now you go to properties sheet and click the ellipses next to rules property this will pop up a dialog you look in this list (At the top) to see the default style classes that are affecting the rendering of the component outlined in red. (You will be able to select different sections of a single component) then you just rewrite the style class that you want to change in your Stylesheet (You will not find the styleclass that you want to change because it is a part of your theme .jar but as long as you name it exactly the same and place in your stylesheet it will override the theme .jar style classes) it's actually very easy -- you were right should be a piece of cake for a guru. Don't have the link handy but you can check out Winston's Blog on changing Table Formatting to get this information...It is EXTREMELY useful if you want your apps to have a custom look and not default that comes with Creator Themes.
Hope this helps you out God knows others have helped me alot!

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.

Java Advanced Imaging - Imaging Client Server application

Hello,
I try to send images compressed from a server to a client, the first Image is received by the client, but nothing append after.
The client send an error that says that the socket connection is closed and I don't know wky !
I am using "JAI" for the image compression on the server and I use the method ImageCodec.createImageEncoder(OutputStream dst, ImageEncodeParam param)
OutputStream is the data stream between the client and the server, I have used DataOutputStream and OutputStream object but I got the same error.
(In an example of JAI they use FileOutputStream, I just change it for OuputStream in order to send data on the socket).
ImageEncodeParam is null.
I use an other socket that permits to launch commands through text command. So text commands and data are on 2 differents sockets.
Every time the client ask to the server for an image and the client wait for the stream data.
I know that it could be easer using RMI but it will be better for me to use a stream.
Could you tell me what way should I take, Could you show me an example?
Thank you in advance,
Regards.

This has nothing to do with imaging.
You are sending something via a socket and that is the problem.
The most likely problems:
1. You are sending/reading text not binary.
2. You are sending data not a message (a message contains data) and thus have no way to determine when the actual message has arrived.
3. You are just doing something wrong with your socket code.

What's the latest stable version of Java Advanced Imaging Image I/O Tools?

Hi,
Could anybody tell me what's the latest stable version for Java Advanced Imaging Image I/O Tools and from where I can download the same?
Thanks

Just 'mark out of date' the package. Or email him directly. The forums are generally the WORST way to try and contact any specific developer.
Oh, and before that, please do a quick google....

Is it possible to load a non-standard image using some Java API?

Hi,
My "problem" is:
1. I have an image called "mediterranean_sea.IMG" (non-standard image format)
2. I need to process it (histogram, palette, etc).
3. I'm wondering if it is possible to load this image an process it using some Java API.
4. I've tried to do this using JAI but I think that this API only works with TIFF, PNG, JPEG, etc.
Any idea?
Thanks in advance,

How to decrease the size of image using a java peogram

Hi All,
I want to decrease the size of an image from MB to KB. I have some images of size around 1MB to 3MB. While displaying all those images in the browser it is taking so much time to download all those and display. So I want to write a Java program to make a duplicate copies of those images, which are small in height and width and display those images in small size. Basically I need to display all the list of images as thumbnail view or list view with faster speed.
Thanks in advance..
Upendra P.

I read the documentation. There is no corresponding Image class. The other
classes are like BufferedImage and all.Yes BufferedImage sounds like what you want.
You could (1) Read the image (2) Obtain its dimensions and create a blank
scaled image (3) Draw a scaled version of the original image using the
Graphics2D obtained from the smaller one. (4) Save the smaller image.
The javax.util.ImageIO class will help with reading and writing the data and
Sun's Tutorial has a section on "2D Graphics".

Problem Printing Images Using JAI

I'm using JAI in an application that prints images. My program works fine on my development machine (Windows XP), but when I put it on my Windows Server 2008 r2-64 bit, it crashes for certain images (these are large images of land plats) that go to a particular printer (OCE PlotWave 300) It prints my smaller images that are printing on a variety of printers just fine (images of Mortgages etc..) and it prints everything just fine on my development machine. What could possibly be causing this?

How do I change Transfer Syntax for DICOM images using sample Java sources?

Hi,
I tested using Note:876534.1 Java API samples. It works fine when I put the "Implicit VR Little Endian" DICOM file.
I could insert the DICOM file, also I could get the all DICOM tags correctly by SQL.
But I could not get all DICOM tags when inserted "Explicit VR Little Endian" and "JPEG Lossy" DICOM file.
Also I could not find how to change the Transfer Syntax to orddicom Java API.
How do I change following simple java source for inserting different Transfer Syntax DICOM file?
Connection conn = DriverManager.getConnection(args[0], args[1], args[2]);
System.out.println("Got database connection");
conn.setAutoCommit(false);
Statement stmt = conn.createStatement();
CallableStatement cs = null;
cs = conn.prepareCall("begin ord_dicom.setDataModel(); end; ");
cs.execute();
cs.close();
String rowInsertSQL = "insert into dicom_test (id, dcmobj) values (" + args[3] + ",ordsys.orddicom())";
stmt.execute(rowInsertSQL);
System.out.println("Inserted empty dicom object ...");
String rowSelectSQL = "select dcmobj from dicom_test where id = " + args[3] + " for update";
OracleResultSet rset = (OracleResultSet)stmt.executeQuery(rowSelectSQL);
rset.next();
OrdDicom dcmProxy = (OrdDicom)rset.getORAData("dcmobj", OrdDicom.getORADataFactory());
rset.close();
System.out.println("selected row for update...");
File testFile = new File(args[4]);
boolean success = dcmProxy.loadContent(testFile, true);
dcmProxy.setProperties();
if (success) {
String updateSQL = "update dicom_test set dcmobj=? where id=" + args[3];
OraclePreparedStatement opstmt =
(OraclePreparedStatement)conn.prepareStatement(updateSQL);
opstmt.setORAData(1, dcmProxy);
opstmt.execute();
int contentLength = dcmProxy.getContentLength();
String SOPInstanceUID = dcmProxy.getSOPInstanceUid();
System.out.println("contentLength: " + contentLength);
System.out.println("SOPInstanceUID: " + SOPInstanceUID);
opstmt.close();
Thanks,
Tatsuya

It would go like this
1. TIFF + XML metadata => DICOM image file
you can use the method ord_dicom.createDicomImage(src blob, metadata xmltype, dest blob) to create the DICOM image in a blob.
2, then use the ORDDicom constructor ORDDIcom(data blob) to create an ORDDicom object
3. then use the ORDDicom processCopy method to change the image properties.
Alternatively you can change image properties on the input TIFF image (using ORDImage methods) then create the DICOM image. If you are happy with the image properties then you can skip step 3.

How to display large image using JAI

dear all,
could anyone tell me how do i display an image which is around
5000x5000 pixels in JAI. I try to use BufferImage to store the image
but JVM throws" out of memory " error while program is running.
thanx a lot!

just a rough estimate, but a 5000x5000 image would require at least 24MB assuming each byte is one pixal, I believe they are 4 bytes per pixel in RBGA format. (5000*5000) = 25,000,000 pixals /1024/1024 = 23.8MB for 1 byte pixals, *4 for 4 byte = 95.3MB. I'm pretty sure that this is how it stores it. Maybe I'm wrong but it certainly explains the situation. assuming you have at least 256MB ramm, run java with -Xmx200M and see what happens.
java -Xmx200M app
or if you have more ramm, like 512, use 450 or 500.
