Reading Tiff image files

Can anybody help me to find out any freeware tools or api to read an image file in tiff format.
The content of tiff file is all text and I have to convert all tiff files into .txt file.
Any help would be appreciated.

Try JAI. A good place to learn how to read files is at http://java.sun.com/j2se/1.4.2/docs/guide/imageio/spec/title.fm.html

A generic error occurred in GDI+ while assing tiff image file to Bitmap and Image

Hi,
I am getting "A generic error occurred in GDI+" error while reading the tiff image file to Bitmap or Image.
Below is my sample code.
string filePath=@"c:\Images\sample.tif";
Bitmap bmp=new Bitmap(filePath); // here getting exception
int totalpages=bmp.GetFrameCount(.....);
etc......
I tried using Bitmap.FromFile() and also from FromStream() even for Image also but there is no use.
Moreover i m having full permissions for the file path and the tiff file is having multiple pages.
Can anyone help me to solve this issue please.
Thanks & Regards,
Kishore

Make sure that the Tif file is valid (can other software open it)? If you are able to save a Tif using GDI+, try saving that Tif, then opening it. Part of me wonders if there is something about that specific Tif that GDI+ doesn't like.
You could also try using WIC to open the TIF, perhaps you would have better luck there.

Error encountered while reading TIFF image, Image may be damaged of incompatible. Resave the image w

I am currently running CS3, windows XP, service pack 2, with recent update, 5.03 installed today.
I just opened a 500 page document not in sections where 90% of the document is a placed PDF.
The PDFS were placed using a sample Script that came with Indesign, that instructs the PDF to automatically flow each page after another.
When scrolling through quickly in the pages pallette, I get the follwing error:-
"Error encountered while reading TIFF image, Image may be damaged of incompatible. Resave the image with different settings and try again."
I click OK.
Then I get the following error.....
" Could not complete request because of database error. The File "ABC.indd" is damaged (Error Code: 3).
Click OK....
Then I get the following error....
Adobe Indesign is shutting down. A serious error was detected. Please restart Indesign to recover work in any unsaved Indesign documents.
Then I get the error.......
Indesign.exe has encountered a problem and needs to close. We are sorry for any inconveneince.
And I have two buttons to click....
Debug or Close.....
If I click Debug, it closes Indesign.
Within this window there is also a window to gather further information....I click it and it tells me...
"Indesign.exe....Error Signature AppName: indesign.exe AppVer: 5.0.3.662
ModName: public.dll ModVer: 5.0.3.662 Offset: 0002e19a"
To view technical inforamtion about the error report, clikc here....
"Then it creates an error report and tells me where the report is located along with a scrollable window of 0xc0000005 and heap of zeros."
The report conatains a whole heap of CHECKSUM ERRORS.
CAN ANYONE PLEASE HELP??
I had these errors before updating to 5.03 and the patch hasn't rectified anything!!

Open the .inx file in CS3 (that's what you have, right?) and save as a new .indd.
I'd also be tempted to open the tiff in Photoshop and do a save as to re-write it.
Let us know if it helps.
Storing files on the network leaves you more open tot he risk of file damage during transfer and save operations.

Accessing a page in a tiled Tiff image file

hi all
I have a tiled tiff image file containing 10 images,please tell me how to process a specific image say 7th image using ordImage process method ,I am using oracle 8.1.7 and win 2000.
regards
Ravi Kiran

Having multiple images in a tiff file is probably not the best practice. THe image object meta data might not make much sense (width, height, format...).
But....
For 8.1.7, there is no way to do it from PL/SQL. You could do it outside the database in a servlet.
For 9i, there is an undocumented interface to allow for access to tiff images other than the first image that is being considered for documentation with 10i.

Loading tiff image file

Hi, I'm trying to load a tiff image onto my GUI and having difficulties carrying out this task. At the moment it reads the image file successfully but can't display the image on the GUI. Does anyone know of any java packages or method i could declear within my program code to solve this problem. Thanks
Regards
Osagie

so display it like this:BufferedImage image = ImageIO.read(file);
ImageIcon icon = new ImageIcon(image);
label.setIcon(icon);But are you sure that you are reading the tiff file correctly? In my machine ImageIO.getReaderFormatNames() outputsBMP,jpeg,bmp,wbmp,gif,png,JPG,jpg,WBMP,JPEGwhich means that tiff files are not supported

Opening tiff image file and finding pixel values at each point

I want to open a tiff image file using java.Than i want to find out the pixel values at each point.Also if possible red,green and blue values.
please mail me answer or code if possible on mail id:
[email protected]

Use Java Advanced Imaging to open the Tiff. There is
a tutorial on it. Look to the left for tutorials, look
for JAI, do what it says.
For getting the pixels, do this:
Use a PixelGrabber to get pixels in array:
int[] pixels = new int[w * h];
PixelGrabber pg = new PixelGrabber(img, x, y, w, h, pixels, 0, w);
pg.grabPixels();
Use a MouseMotionListner for
mouseMoved(MouseEvent moueEvent)
pixel = pixels[mouseEvent.getX() + (mouseEvent.getY()*width)]
int alpha = (pixel >> 24) & 0xff;
int red = (pixel >> 16) & 0xff;
int green = (pixel >> 8) & 0xff;
int blue = (pixel ) & 0xff;
Look up the API for MouseMotionListener, PixelGrabber, etc...

Reading a image file and printing it by a Servlet

In a IMAGE TAG of HTML file i am calling servlets what will write a image to the browser.
<IMG SRC="http://localhost/WriteImage" width="50" height="100">
The Servlet WriteImage has to read a image from a location(it could be gif,jpeg,png or another format of images ) and it has to write to the above image tag.
Anyone can u help me out how i can do this...
I tried out with javax.imageio package but couldn't get it.
Thank Q
Vijay

Your WriteImage servlet needs to read the image file in from wherever it is (hard drive, database, whatever), then write it back out to the browser. To do that, first use the HTTPServletResponse object to send the appropriate headers, then call the getOutputStream() method to get an output stream to write the data to. This data will be sent to the browser which, if you've set the headers correctly, will display it as an image.
It's been a long time since I did this (we abandoned storing images in databases quite a long time ago), so I can't be more specific than that, but hopefully that'll be enough to get you going. If you run into any problems, reply and I'll see if I can help further.

Signed Applet can't read an image file??

Hi my dear java folks,
I've written a simple applet and self-signed it in order to have access
to local machine's files.
The applet as you see needs to read an image file (arrow.gif).
The applet is:
import.....
public class MyApplet extends JApplet{
JButton button1=new JButton("Save");
JButton button2=new JButton(new ImageIcon("arrow.gif"));
public void init(){
button1.setBounds(10,70,80,20);
button2.setBounds(10,100,80,20);
getContentPane().setLayout(null);
getContentPane().add(button1);
getContentPane().add(button2);
The java.policy file is:
keystore ".//myworkingstore.store";
grant codeBase "http://fin2000/htdocs/MyApplet.class" {
permission java.io.FilePermission "<<ALL FILES>>","read";
permission java.io.AllPermission;
grant codeBase "." signedBy "MyName" {
permission java.io.FilePermission "${user.home}/*.*","read,write";
permission java.io.FilePermission "<<ALL FILES>>","read";
permission java.io.AllPermission;
The java.security file is on the server
(on my server I have Oracle8.1/Apache installed):
policy.url.1=file:d:/oracle/ora81/apache/apache/htdocs/java.policy;
My problem is when I run my applet through a html file
"http://myServerName/test.html" in my browser, the applet
runs correctly except it's button2 (the iconized button), the
button comes without it's ImageIcon on it.
I receive no errors, no messages and no signs of error
I am completely confused!
Need Urgent Help
Thank you , Jamanir

Hi,
this has nothing to do with a security problem.
Change you code as follow:
JButton button2 = new JButton(new ImageIcon(getClass().getResource("arrow.gif")) ;Pack arrow.gif in the same directory/package as MyApplet.class in the jar file and It should solve your problem...
The problem is that when you write new ImageIcon("arrow.gif"), it works locally as a standalone application, because "arrow.gif" is mapped to the current directory where you application is started from. This has no meaning when you works online with an applet. That's the reason why your graphic was not found.
getClass().getResource("arrow.gif") returns an URL pointing to a file "arrow.gif" located at the same location as the class. This always works either locally or online, other packed in a Jar file, or unpacked.

Reading TIFF images without IMAQ vision

Hi,
Is there anyway to read TIFF images with LV 7.1 but without IMAQ vision? I know it's possible for PNG, BMP and JPEGs, but seems impossible to read TIFFs without IMAQ Vision.
Thanks.
Kian

LabVIEW doesn't do this automatically, but maybe someone has a VI they're willing to share.
Another possibility would be to use an external program to convert the TIFF to another format (BMP for example) and then to read in the BMP picture.
If you're looking to write something yourself, then this might help.
Hope this helps
Shane.

Reading only Image files from a directory

i am wanting to be able to read a directory but only obtain the Image files (ie, gif, jpeg, tiff, png etc) and ignore all other type of files.

it shouldnt be new FileFilter() there, it should be new ImageFilter() but it gives a compilation error saying i cannot apply that parameter to the listFiles() method in the File class

I'm confused.
You already ARE using a FileFilter to only pick up image files. Whats the problem?
If you need to recurse directories you need to change your code only a little.
Write your method
JFileChooser fc = new JFileChooser();
fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
//Handle open button action.
int returnVal = fc.showOpenDialog(MainAppGUI.this);
if (returnVal == JFileChooser.APPROVE_OPTION) {
dir = fc.getSelectedFile();
if (dir.isDirectory()) {
scanDirectory(dir);
else{
// not a directory
public void scanDirectoryForPhotos(File directory){
// taking your code
if (dir.isDirectory()) {
File[] files = dir.listFiles(new ImageFilter());
for (int i = 0; i < files.length; i++) {
    if (files.isFile()) {
// details deleted
// recurse through directories
else {
scanDirectory(files[i]);
Your exception handling is a little strange. You throw an exception only to catch it immediately to print a stack trace? Not exactly the most common handling I've seen. You should probably just throw the exception and let the next level down handle it.

Reading TIFF image in YcbCr photometric interpretation

Hi,
Can anyone tell me what needs to be modified in the following code snippet to read a TIFF image having the YcbCr photometric interpretation.
File file = new FILE(filename)
SeekableStream stream = new FileSeekableStream(file);
ImageDecoder decoder = imageCodec.createImageDecoder("tiff",s,null);
RenderedImage image = dec.decodeAsrenderedImage();
ScrollingImagePanel panel = new ScrollingImagePanel( image,image.getWidth(),image.getHeight());
The following code reads the image but assumes RGB photometric interpretation.
Any info will be helpful.
Thanks,
Panna

try this:
File file = new FILE(filename)
SeekableStream stream = new FileSeekableStream(file);
//add these lines
TIFFDecodeParam tiffparam = new TIFFDecodeParam();
tiffparam.setJPEGDecompressYCbCrToRGB( false );
//change the following line
ImageDecoder decoder = imageCodec.createImageDecoder("tiff",s,tiffparam);
RenderedImage image = dec.decodeAsrenderedImage();
ScrollingImagePanel panel = new ScrollingImagePanel( image,image.getWidth(),image.getHeight());
hope this helps!

How can I read a image file through URI?

I have a image file store in my computer's Image directory on drive E. I name the pathname as:
file:////MyComputerName/e:/image/
the image filename is MyImage.JPG
so I create a ImageIcon use:
String uri = "file:///MyComputerName/e:/image/";
String imagefilename = "MyImage.JPG";
ImageIcon ii = new ImageIcon( uri+imagefilename);
Image myimage = ii.getImage();but I can not get the image.
Does anyone know what's wrong?
Thank you

Read the documentation for ImageIcon(String path) -- the String is a file path,
not a URL. If you want to pass a URL to ImageIcon, use ImageIcon(URL url).
So, either of the following works:
URL url = new URL("file:///e:/image/MyImage.JPG");
ImageIcon imageIcon1 = new ImageIcon(url);
String path = "e:/image/MyImage.JPG";
ImageIcon imageIcon2 = new ImageIcon(path);In case you even need it, to convert a file into a URL, you can write:
URL url = file.toURI().toURL();And finally, you may want to check out BufferedImage and ImageIO.
You can read in a BufferedImage in one line:
BufferedImage image = ImageIO.read(file_or_url_etc);and a BufferedImage offers may advantages over a plain old image.

Reading in image files

Just a quick question.
I'm reading in an image file (.gif) and i need to write it to a file (basically make a copy of it).
I'm using a FileReader but this seems to skew the image, what should i use instead of this?
Thanks

Got it myself, thanks anyway
BufferedInputStream in = new BufferedInputStream((new FileInputStream(theFile)));

Read .RAS image file

I have a image file (src.ras) and I want to read it and convert it into Binary image.
I am reading it and then I want to find the height and width of it using
int w = image.getWidth();
int h = image.getHeight();
then I am getting error

If any suggestion or any body know whats the problem plz let me know.....

Read the API for ImageIO.read (file):
If no registered ImageReader claims to be able to read the resulting stream, null is returned.
Add these line in your code and tell us what gets printed:public class Main {
   public static void main(String[] args) throws IOException {
