I need to combine >1 tiff to create a multi-page tiff.

From previous post, I can't get this line to compile:

import java.io.IOException;
import java.io.*;
import java.util.*;
import java.lang.Object;
import java.lang.String;
import java.lang.Integer;

public class mergeTifs  {    
    public static void main (final String args[]) throws Exception {
        doTifs(args);
    }

    public static void doTifs(String args[])  {
        try {
            List<IIOImage> imageList = new ArrayList<IIOImage>();
            ....

I get this error msg:
mergeTifs.java:22: '(' or '[' expected
            List<IIOImage> imageList = new ArrayList<IIOImage>();

I can't figure this error. Any thoughts ? Thanks !

What version of Java are you using to compile?

Hie guys! After waiting long time for getting a workable code to merge multi-page tiffs into one tiff, i am posting my solution what i got workable few minutes ago. Thanks in advance to 'lasmith' for the idea how to do it. Main difficulty was to iterate through multi-pages in a tiff file to load it to be merged. How erver, here is my code....

public static void concateTiff(String[] inputTiffs, String outputTiff) {
                List<IIOImage> imageList = new ArrayList<IIOImage>();
                ImageInputStream tiffStream = null;
                IIOImage tiffImage = null;

                try {
                        // locate a TIFF reader
                        Iterator<ImageReader> tiffReaders = ImageIO.getImageReadersByFormatName("tiff");
                        if (!tiffReaders.hasNext())
                                throw new IllegalStateException("No TIFF reader found");
                        ImageReader tiffReader = tiffReaders.next();

                        for (int i = 0; i < inputTiffs.length; i++) {
                                System.out.println("image-" + i);
                                // point it to our image file
                                tiffStream = ImageIO.createImageInputStream(new File(inputTiffs[i]));
                                tiffReader.setInput(tiffStream);
                                // read pages until end of image from the TIFF file
                                try {
                                        for (int index = 0;; index++) {
                                                tiffImage = tiffReader.readAll(index, tiffReader.getDefaultReadParam());
                                                imageList.add(tiffImage);
                                        }
                                } catch (IndexOutOfBoundsException ex) {
                                        System.out.println("page limit crossed!");
                                }
                        }

                        Iterator<ImageWriter> writers = ImageIO.getImageWritersByFormatName("tiff");
                        ImageWriter writer = writers.next();
                        ImageOutputStream ios = ImageIO.createImageOutputStream(new File(outputTiff));
                        writer.setOutput(ios);

                        IIOImage firstIioImage = imageList.remove(0);
                        writer.write(firstIioImage);
                        int i = 1;
                        for (IIOImage iioImage : imageList) {
                                writer.writeInsert(i++, iioImage, null);
                        }
                        ios.close();
                        tiffStream.close();
                } catch (IOException e) {
                        System.out.println("error merging tiff. Msg=" + e.getMessage());
                }
        }

Hope it would help.

Thanks for posting the code. If it did not come through accurately try
reposting to {interest _AT_ jai.dev.java.net} or send it to me and I will post
it.

Dear Brian,

In your reply the i can see the complete code as I posted. But in my posting, code fragment is missing. People can use my code from ur posting.

Thanks for immediate attention!

I have no clue as to what error would provoke that message. It would be more helpful to post the actual stack trace.

I always get this exception IllegalStateException:No TIFF reader found:
but I change "tiff" to "jpg"  still same exception



Iterator<ImageReader> tiffReaders = ImageIO.getImageReadersByFormatName("tiff");
if (!tiffReaders.hasNext())
throw new IllegalStateException("No TIFF reader found");
