Hi Guillaume,
here comes a main class that works. You have only to set the paths for the
source and target file (or rewrite the main method to use the args array
instead).
Dependency is Apache commons-io.
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import org.apache.commons.io.IOUtils;
public class ConverterMain {
private final PdfBoxJpgConverter converter = new PdfBoxJpgConverter();
public static void main(String[] args) throws Exception {
File source = new File(<insert your jpg file here>);
File target = new File(<insert your target pdf file here>);
new ConverterMain().convert(source, target);
}
private void convert(final File source, final File target) throws Exception
{
if (!target.exists()) {
target.getParentFile().mkdirs();
target.createNewFile();
}
InputStream in = null;
OutputStream out = null;
try {
in = new FileInputStream(source);
out = new FileOutputStream(target);
this.converter.convert(in, out);
} finally {
IOUtils.closeQuietly(in);
IOUtils.closeQuietly(out);
}
}
}
Happy holidays,
Florian

Betreff: Re: To PDF/A converted JPG has corrupt XMP-Metdata
Hi,
Could please create and send me a main class doing the stuff ? I will have a
look to your problem.
KR,
Guillaume
