Convert Ascii String to Tif file format content

[Angela D'souza]

How can I do this?
Thanks

Tiff is an image type. So, what you would need to do is create an .tif image of the text that you have. Java has a package "jai - Java Advanced Imaging API". You could use that.
I had made a class that creates an image stream of tiff type. You could then create a new file and store the image in it.
Here is the class ....

import javax.media.jai.JAI;
import javax.media.jai.TiledImage;
import java.awt.image.MultiPixelPackedSampleModel;
import java.awt.image.SampleModel;
import java.awt.image.DataBuffer;
import java.awt.image.ComponentColorModel;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.Font;
import javax.media.jai.RasterFactory;
import com.sun.media.jai.codec.ImageCodec;
import com.sun.media.jai.codec.TIFFEncodeParam;
import java.io.ByteArrayOutputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.HashMap;

public class CreateTIFF
{
    private ByteArrayOutputStream stream = null;
    
    public CreateTIFF(){}
    
    //Takes in the text to be displayed in the image.
    public CreateTIFF(String[] text)
    {
        TiledImage image = null;
        Graphics2D graphics = null;
        SampleModel model = null;
        ImageCodec codec = null;
        TIFFEncodeParam param = null;
        int yIndex = 30;
        HashMap map = null;
        int fontSize = 30;
        
        model = new MultiPixelPackedSampleModel(DataBuffer.TYPE_BYTE,2400,3000,1);
        image = new TiledImage(0,0,2000,2500,0,0,
                               model,
                               ImageCodec.createGrayIndexColorModel(model,false));
                               
        graphics = image.createGraphics();        
        
        map = new HashMap();
        map.put(RenderingHints.KEY_TEXT_ANTIALIASING,                RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
        graphics.setRenderingHints(map);
        graphics.setFont(new Font(null,Font.PLAIN,fontSize));
        
        for(int i = 0; i < text.length; i++)
        {
            graphics.drawString(text[i], 50, yIndex);
            yIndex += fontSize+5;
        }
               
        stream = new ByteArrayOutputStream();
        
        //Setting the compression to be used.
        param = new TIFFEncodeParam();
        param.setCompression(TIFFEncodeParam.COMPRESSION_GROUP4);
        
        JAI.create("encode",image,stream,"TIFF",param);
    }
    
    public static void main(String args[])
    {
        FileOutputStream file = null;
        CreateTIFF image = null;
        
        if (args.length < 1)
        {
            System.out.println("Enter the String to be created");
            System.exit(-1);
        }
        
        //Create the byte Stream of the image to be display.
        image = new CreateTIFF(args);
        
        //Store the image in a file.
        try
        {
            file = new FileOutputStream("image.tiff");
            file.write(image.getStream().toByteArray());
            file.close();
        }
        catch(IOException ioExp)
        {
            ioExp.printStackTrace();
            System.out.println("The error " + ioExp.toString());
        }        
    }        
    
    public ByteArrayOutputStream getStream()
    {
        return stream;
    }
    
    public void setStream(ByteArrayOutputStream stream)
    {
        this.stream = stream;
    }
}

Thanks for this program.

if the string is large as shown below, then in the tiff file the below string should be shown as

hello world hello world hello world hello world hello world hello world hello world hello world hello world hello world hello world
hello world hello world hello world hello world hello world hello world hello world hello world hello world hello world hello world

but only few hello world is written to tiff file.
Also can you please let me know if it is possible to format the string as it is and write to tiff file.

String bigString = "hello world hello world hello world hello world hello world hello world hello world hello world hello world hello world hello world \n"
+ "hello world hello world hello world hello world hello world hello world hello world hello world hello world hello world hello world \n";


  

thanks a lot
appreciate your help

Thanks,
Deepak

So this is a new requirement. It pays to give us ALL of the information at the start.

Not being an image expert I don't have much else to offer beyond: Why do you need to do this?

Converting text to an image doesn't seem to me like a particularly sensible thing to do, since the resulting image is
likely to be waaay bigger than the original text.

PS: The lines in your last post are far too long.

Having implemented the email-address-as-an-image display here on this site I beg to differ; size is unlikely to play a role in this. But I do admire Deepak's confidence that someone who hasn't posted here for 11+ years might still be listening to the conversation

These days one shouldn't use JAI, though, (which is obsolete), and no com.sun.* classes. The javax.image.ImageIO class would be helpful instead.

Dang! I always get caught out by those. Colour me "Doh-h!".

thank you for the response.

able to wrap the test using org.apache.commons.lang.WordUtils;
as shown below.

	public void formatEmailBody(Graphics2D graphics,String emailStuff){	
		System.out.println(emailStuff);
		String[] paragraphs = emailStuff.split("\n");
		int line = 100;
		for(String para : paragraphs){
			String strWrap = WordUtils.wrap(para, 75);
			String[] strWarpArr = strWrap.split("\n");
			for (String strWrapLine: strWarpArr){
					graphics.drawString(strWrapLine, 50, line);
					line += 50;
					}
		}
	}

however with the below image code,

model = new MultiPixelPackedSampleModel(DataBuffer.TYPE_BYTE,2400,3000,1);
image1 = new TiledImage(0,0,2000,2500,0,0,model,ImageCodec.createGrayIndexColorModel(model,true));
graphics = image1.createGraphics(); 

am getting the image background color as BLACK and font color as WHITE on windows server 2008 R2 enterprise, Service pack1, 64 bit OS.

and the same code am getting background color as WHITE and font color as BLACK on windows XP professional, version 2002, servcie pack 3, 32 bit.

am just quoting the machine configuyrations, am not sure if that is the probelm in different colors.
can somebody please let me know what could be the issue?

Thanks,
Deepak
