Hi, I have faced a similar problem and solved it using the morena api http://www.gnome.eu/Twain/examples/studio.html
Problem is the scanner works fine with TWAIN, but with SANE, it is totally failing. There is a permanent connection refusal form the scanner ip whenever
i try to use a network scanner. I am not sure how to solve it. If anyone has solved this please revert back.

Reading Images from JAR Files

Hi,
I am having a very difficult time being able to read images from a JAR file via my Applet. I have tried everything that I know about with no luck. The only way I can get this to work is to store the images individually in a sub directory of public_html on the websever. This works, but I would like the images to come down in a JAR file for performance reasons.
I am using Internet Explorer 5.5 for my browser. I checked the options and everything seems to be in order, but......
I would appreciate any feedback that anyone might have on this topic..........
Thank You....

once in a jar file i inserted a image
the jar file on clicking starts an frame.
so the image was for getting that image at the icon place at top and at minimized window
i could not get that image from jar file by new imageicon().getimage();
but i get the image if it is in the directory in which jar file is.....
can one explain the reason

I am facing a Problem with reading images from database

Hi everybody..
any help will be most appreciated, I am facing problem with reading images from database. I am pasting my code...
string connect = "datasource = localhost; port = 3306; username = root; password = ;";
MySqlConnection conn = new MySqlConnection(connect); // creating connecting string
MySqlCommand sda = new MySqlCommand(@"select * from management.add_products ", conn); //creating query
MySqlDataReader reader;
try
conn.Open(); // Opening Connection
reader = sda.ExecuteReader(); // Executing my Query..
while (reader.Read())
byte[] imgg = (byte[])(reader["Picture"]);
if (imgg == null)
pc1.Image = null;
else
MemoryStream mstream = new MemoryStream(imgg);
pc1.Image = System.Drawing.Image.FromStream(mstream);
It says Parameter not Valid... i am reading all the images from database

I agree with Viorel. You are getting the error because the format of the data is incorrect probably because the data was modify. It may not be the reading of the database the is incorrect, but the application that wrote the data into the database. You need
to compare the imgg array data with the data before it was written to the database to see if the data matches. I usually start by comparing the number of bytes which is easier to check then compare the actual to isolate which function is changing the
byte count.
An image is binary data. The standard VS methods for reading and writing data (usually stream classes) default to ASCII encoding which will corrupt binary data. The solution usually is to use UTF8 encoding instead of the default ascii encoding.
Ascii encoding with stream often aligns the data and adds extra null bytes to the end of the data which can produce these type errors.

Read images from external jar file (Sun's Java L&F Graphics repository)

Hi!
I don't know how to read images from an external jar file. Sun has a Java Look and Feel graphics repository that contains a lot of good images that can be used on buttons and so on. This repository is delivered as a jar file, containing only images, and I want to read the image files from that jar file directly without including them inside my application jar file. The application and image jar files will be in the same directory.
I have absolutely no clue how to solve this. Is it necessary to include the images inside my application jar file or is it possible to have them separate as I want.
Would really appreciate some help!
Best regards
Lars

Hi,
There is two ways :
1) Add your jarfile to the classpath.
Use the class loader :
URL url = ClassLoader.getSystemResource("your/package/image.gif");
Image im = (new ImageIcon(url)).getImage();
or
Image im = Toolkit.getDefaultToolkit().getImage(url);2)If you don't want to add the jar to the classpath you can use this (under jdk 1.4):
import java.util.*;
import java.util.jar.*;
import java.awt.*;
import java.io.*;
import java.awt.image.*;
import javax.imageio.*;
public class ImageUtilities {
     public static Image getImage(String jarFileName, String fileName) {
          BufferedImage image = null;
          try {
               JarFile jar = new JarFile(new File(jarFileName), false, JarFile.OPEN_READ);
               JarEntry entry = jar.getJarEntry(fileName);
               BufferedInputStream stream = new BufferedInputStream(jar.getInputStream(entry));
               image = ImageIO.read(stream) ;
          catch (Exception ex) {
               System.out.println(ex);
          return(image);
}I hope this helps,

Read images from a jar file?

Hello, I'm converting a 6i app to 10g. This app does a ton of read_image_file() calls to
change GIF images on the screen based on user actions. In 6i the images are all stored on the local hard drive. The images are not icons for buttons, but images that appear in different locations on the screen.
For 10g, is it possible to leave the images in a jar file and effectively read the images from that? Otherwise, I suppose I'm looking at using webutil functionality to download the jar file and unjar it into an images directory for reading from the client?
Any best-practice scenario for this sort of thing?
Thanks for any info,
Gary

We are migrating from 6i to 10g too. And I try to not use webutil. All my pictures (icons gif files) are in a jar file.
Just make attention of the size of your pictures. The jar file is loaded when you launch the application (the first time, and after, only if the jar file has changed).

Need to read image from scanner

Hi,
I wnat to load image from scanner directly into forms. Then save it into table.
Shahin

Here we are..
This is my "bean" for scanning over twain driver or SANE (linux)..
I have used morena twain drivers (JNI), apache httpclient library for java (i need it for http communication between forms and database) and Itex pdf library for java.
The bean has three options..
1. you can select the twain device and start to scan
2. you can view scanned images
3. you can generate PDF from scanned images and store it to local disk or database..
For example how the form look like:
!http://freeweb.siol.net/peterv6i/scan1.jpg!
On the first form you can start a new scann or just delete the temporary files in the local folder (user temporary folder).
After you press the "scann" button the twain dialog apear
!http://freeweb.siol.net/peterv6i/scan2.jpg!
The dialog of twain device will startup. Here you can set everythig you can (scann area, colors, dpi ...)
!http://freeweb.siol.net/peterv6i/scan3.jpg!
The scanned images are transfered on local disk (temp folder). Every scanned images got timestamp value as name of the image (on the picture this are located in the select list)
!http://freeweb.siol.net/peterv6i/scan4.jpg!
If you click on the item the scanned image will aper on the screen
!http://freeweb.siol.net/peterv6i/scan5.jpg!
The last screen is for saving / generate a pdf from the array of images or image.

How Read image from slingRequest

Hi,
We have a user input form which contains input file (image) selection. When user submits the form, we want to read the file selected by user and store it as base 64 encoded data. We have following code to do the same. This code gets executed when the form is submitted.
//Read image data from slingRequest
String userImage1 = slingRequest.getParameter("userImage1");
//Apply base 64 encoding on the data received in slingRequest
String encodedUserFile = "";
byte[] userFileBytes = userImage1.getBytes();
encodedUserFile = Base64.encodeBase64String(userFileBytes);
These statements are not throwing any error. But, when I try to apply base 64 decoding on the contents available in 'encodedUserFile', its' not the image user uploaded. There seems to be some problem, which I am not able to figure out. Can someone please help me with this?

Hi,
You need to use the Sling RequestParameter interface to get an uploaded file.
See:
http://sling.apache.org/site/request-parameters.html

Reading images from URL without knowing the format

I have an image url like this: http://example.com/image.php?id=5605. How do I get the actual image from such an URL? I have tried using ImageIO.read and loading the url directly into an ImageIcon without success.

yeah,
I knew a little about linearization and but the idea was to help quick loading the very first page of a document while the rest of the data still is arriving. Not exactly what I needed here.
Anyway, you have just confirmed my fears, I will have to know the document size, where exactly it ends on my stream, in order to correctly load it.
I appreciate your help sir. Thanks for your time.
Best regards.

How to read image from mssql db?

how to read an image stored in mssql database .and how to display that image in html page through servlet.
thanks in advance,
Rassam

Here are the steps you can do
1) Write JDBC code to read the image from database. You will have to use
ResultSet.getBlob("columnname") method.
2) Write this blob object on to server filesystem using java.io at a defined location
3) Give link in your HTML page for this defined location.
(You can do all of this in your servlet.)
I have given very high level steps. Let me know if you want detailed steps.

Read Image from client

I am trying to import the picture from the client, using WEBUTIL (v 1.0.2)
Procedure looks like:
DECLARE
FILE_NAME VARCHAR2(200);
File_Filter varchar2(30):='JPEG Files (*.jpg)|*.jpg|';
BEGIN
FILE_NAME:=CLIENT_GET_FILE_NAME(NULL,NULL,File_Filter,NULL,OPEN_FILE,TRUE);
CLIENT_IMAGE.READ_IMAGE_FILE(FILE_NAME, 'JFIF',
'<table>.<BLOB column>');
END;
"CLIENT_GET_FILE_NAME" works fine, but when it comes to "CLIENT_IMAGE.READ_IMAGE_FILE" I get message
Checking through the debugger I found that the error is generated in the
WEBUTIL.WEBUTIL_CORE.CHECKJAVA
at the line
classpath := JAVA_SYSTEM.getProperty('java.class.path');
I checked, and all CLASSPATH variables in registry contain the path to webutil.jar
I also tried with: "webutil_file_transfer.Client_To_DB_with_progress"
And it works fine to me, file is transferred to the BLOB field but then I can not display the image in the form. (Is there any advice on how to do this, any example code)
I have been using iDS9.
Is there anyone who could help. Thanks in advance
Sead

What is really odd to me is the fact that the value in "classpath" after the command
classpath := JAVA_SYSTEM.getProperty('java.class.path');
does not correspond to any variable in the registry.
I searched the registry and the value of the string does not exist in any variable in the registry. I do not know how did "JAVA_SYSTEM.getProperty('java.class.path')" produce the classpath string.
