Reverse translating a PS file
Hi All,
I just made with a java program shown below that makes: GreenGlobe.gif
->aGif2PSFile.ps.
Is there any way with a java program to reverse that programming:
aGif2PSFile.ps->GreenGlobe.gif?
I used this program below:
import java.io.*;
import javax.print.*;
import javax.print.attribute.*;
import javax.print.attribute.standard.*;
/*
* Use the Java(TM) Print Service API to locate a service which can
export
* a GIF-encoded image to a stream as Postscript. This may be spooled to
a
* Postscript printer, or used in a postscript viewer.
*/
public class PrintGIF2PSStream {
public static void main(String args[]) {
/* Use the pre-defined flavor for a GIF from an InputStream */
DocFlavor flavor = DocFlavor.INPUT_STREAM.GIF;
/* Specify the type of the output stream */
String psMimeType = DocFlavor.BYTE_ARRAY.POSTSCRIPT.getMimeType();
/* Locate factory which can export a GIF image stream as Postscript
*/
StreamPrintServiceFactory[] factories =
StreamPrintServiceFactory.lookupStreamPrintServiceFactories(
flavor, psMimeType);
if (factories.length == 0) {
System.err.println("No suitable factories");
System.exit(0);
}
try {
/* Load the file */
FileInputStream fis = new FileInputStream("GreenGlobe.gif");
/* Create a file for the exported postscript */
String filename = "aGif2PSFile.ps";
FileOutputStream fos = new FileOutputStream(filename);
/* Create a Stream printer for Postscript */
StreamPrintService sps = factories[0].getPrintService(fos);
/* Create and call a Print Job for the GIF image */
DocPrintJob pj = sps.createPrintJob();
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
//aset.add(new Copies(2));
aset.add(MediaSizeName.ISO_A4);
//aset.add(Sides.TWO_SIDED_LONG_EDGE);
//aset.add(Finishings.STAPLE);
Doc doc = new SimpleDoc(fis, flavor, null);
pj.print(doc, aset);
fos.close();
} catch (PrintException pe) {
System.err.println(pe);
} catch (IOException ie) {
System.err.println(ie);
}
}
