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.

Import Image from scanner to database Direct ..

can any Colleagues help me ..
how can i Import Image From Scanner directly
if anyone can descuss code and how can i do that
thank for all Colleagues .......

You cannot.. unless you are prepared to get your hands dirty writing code to integrate a scanner API into Oracle.
Oracle has a feature called extproc. This allows you to define external "procedures" - these procedures are for example shared object libraries (Linux/Unix) or dynamic link libraries (Windows). A scanner API will be typically implemented by its driver as a shared object/DLL. Which means it is callable from within PL/SQL.
It may however not be usable - extproc does not support callbacks, does not own a window or process handle, and so on.
In which case you may need to wrap the DLL into a custom DLL that implements callbacks. perhaps create a hidden window if a window handle is needed, and so on.
In other words, this is not a trivial thing. You need to know more than just a bit about o/s side (systems) programming.
You should also ask yourself why you want to do this. Architecturally wiring a scanner into Oracle via PL/SQL and an extproc interface make absolutely no sense at all.
Especially since operator input/control is required to physically manage device... That is on the very opposite side of the Oracle server spectrum. That is clearly a client function to interact with such a device and not a server function.

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,

Importing image from scanner

How can I import an image from my scanner (Epson Artisan 837) directly into Photoshop 5? When I go to import, there is ONLY the message: "Video Frames to Layers"...whatever that means. I don't know how I can now use Photoshop to open my scanner and import images like I could with an older version of Photoshop.

Before anyone can help you, they will need what OS you are using and the version of the OS as the scanner driver differs for each OS and version.

PSE10- Possible to multi-crop images from scanner?

I'm taking the task of digitizing hundreds of old photos. Currently, using my flatbed scanner, I scan 4 pics at a time. Then I use PSE10 Editor's tool of "Divide Scanned Photo" to split the pictures into 4 different files. However, sometimes this tools doesn't recognize all 4 pics correctly and I have to crop manually. This can be tedious to crop, save, open the old file again, crop, save....and do this 4 times. Is there a way to select multiple crop images from a file and export each to a new file?
Any advice is appreciated on my tedious task.

Thanks Barbara. I have a really old flatbed HP scanner and am using regular Windows fax & scan to capture the images. It's my understanding that newer HP scanners come with this type of software. Didn't really want to invest in a new scanner. I've tried a few trials of scanning software, but found PSE10 actually does a better job than them in it's dividing scanner pics. I'll just deal with the ones that it can't handle manually. Maybe we'll see a feature where we can crop and export multiple parts of a file in a future release.

PS CS6 trial crashes after importing huge image from scanner

Hi.
Here is my hardware:
   Macbook pro 4 GB DDR3 core i5 with plenty of HD space
   Epson V700 scanner (6400 dpi scanning capability)
My Software:
   Adobe CS6 trial
What I want to do:
   Scan a typical photo that is 6 by 6 inches at 6400 dpi as a bitmap, for utmost quality
What I tried:
   File -> Import -> Images from device -> then selected my scanner, set it to scan at 6400 dpi and save as a bitmap
My problem:
    When the scanner head is done scanning and the progress bar for scanning the image completes and moves to the next step (presumably writing the image to the file), PS crashes and gives me an error log. It is far too detailed for me. I have no problem scanning images at lower resolutions like 1200 dpi. But this scanner is capable of 6400 dpi and I want to take full advantage of it. I cannot use the scanner software that came with teh scanner because tech support told me the scanner software has a 1.something GB file limit size. They told me 3rd party software like PS should be able to scan unlimited file sizes.
   I suspect the file size migh be too large (16 GB)
My question:
   Is this a bug in the trial or something? Should PS be able to scan a 6 by 6 inch photo at 6400 dpi and save it as a bitmap?
Any 1st thoughts? I imagine it would be useful to upload the error log. I can do that if it is ok to do so
Thanks, your help is appreciated since I would lik eto scan this image at 6400 dpi. If I am given a solution, I will probably buy the full version

That's a bigger image than photoshop elements can handle (the pixel dimensions are roughly 38,400 x 38,400)
I suspect the problem in cs6 is more due to lack of ram on your machine (compared to the file size), but you should really ask about cs6 on the photoshop forum:
http://forums.adobe.com/community/photoshop/general
Also unless the photo is a slide or negative, you probably don't need to scan at max resolution.
Anyway for elements you'd need to reduce either the dpi or specify a smaller size than 6 x 6.
And then probaly scan (save) to your hard drive instead of scanning from within elements to a file format such as tif with compression if the scanner offers that option.
It depends on what your scanning, but for example i usually scan 35 mm slides at 4800 dpi (different scanner) at there default size (24mm x 36mm) and the file size is usually in the 200 to 300 mb range.
