I have a problem where a JPEG image is not showing in a PDF. I am using
iText 2.1.5, Java 6, and Adobe Acrobat 8.1. I have written a test
program to simplify showing the problem. The JPEG is loaded into the
Image class using getInstance and passing the URL of the file. The image
does show up in the PDF but it is blank, meaning that if I click in the
PDF I can find the image and do a copy. The copy however only produces a
blue background. I have tried other PDF creation software (such as
CutePDFWriter) and the image displays in the PDF just fine. I have also
tried with the Jpeg class and get the same errors. The Jpeg2000 class
gives me an invalid JPEG error message as part of an IO Exception. Any
help is greatly appreciated.
Here is the code:
import java.io.FileOutputStream;
import java.io.IOException;
import com.lowagie.text.*;
import com.lowagie.text.pdf.PdfWriter;
import java.awt.image.BufferedImage;
import java.io.RandomAccessFile;
import java.net.URL;
/**

*/
public class PDFPrototype {
/** Creates a new instance of PDFPrototype */
public PDFPrototype() {
}
public static void main(String args[]) {
// Use the iText package to create various PDF documents and see
what memory usage is
// step 1: creation of a document-object
int numPages = 4;
System.out.println("Start Time for " + numPages + ": " +
System.currentTimeMillis());
try {
Document document = new Document();
// step 2:
// we create a writer that listens to the document
// and directs a PDF-stream to a file
PdfWriter.getInstance(document,
new
FileOutputStream("c:\\projects\\PDFPrototype\\PDFPrototype2.pdf"));
// step 3: we open the document
document.open();
document.setPageSize(PageSize.LETTER.rotate());
// step 4: we add a paragraph to the document
for(int i = 0; i < numPages; i++) {
document.newPage();
document.setPageSize(PageSize.LETTER.rotate());
URL url = null;
BufferedImage bufImg = null;
RandomAccessFile raf = null;
Image jpg = null;
if(i % 2 != 0) {
// This image does not show
document.add(new Paragraph("JPEGNotvisibleinPDF2"));
url = new URL("file", "localhost",
"c:\\projects\\PDFPrototype\\src\\images\\JPEGNotvisibleinPDF2.jpg");
jpg = Image.getInstance(url);
jpg.scalePercent(40.00f);
document.add(jpg);
} else {
// This image does show
document.add(new Paragraph("JPEGNotvisibleinPDF"));
url = new URL("file", "localhost",
"c:\\projects\\PDFPrototype\\src\\images\\JPEGNotvisibleinPDF.jpg");
jpg = image.getInstance(url);
jpg.scalePercent(40.00f);
document.add(jpg);
}
document.newPage();
}
System.out.println("End Time for " + numPages + ": " +
System.currentTimeMillis());
// step 5: we close the document
document.close();
} catch (DocumentException de) {
System.err.println("Caught Document Exception: " +
de.getMessage());
de.printStackTrace();
} catch (IOException ioe) {
System.err.println("Caught IO Exception: " +
ioe.getMessage());
ioe.printStackTrace();
}
}
}
