Thank you,
I guess I'm off to look for a tool to create PostScript files out of Java.
Thank you all for your help with my question :)
I think Apache FOP can also generate PS files.

Hi Tilman,
Thank you for the reply. I don't see how that post was the same as mine and is
answered. Forgive me.
I tought you were the same person, some of the code looked identical. If not -
sorry! Some users ask the same question on SO and here.
That question was "What do I need to change to create a reasonably sized PostScript
file?" The only answer that I see is that PostScript files are big by nature.
Sadly, yes.
My question was, "Is there a way in PDFBox to have it put the text directly into the
PostScript file instead of passing it on as part of an image?" Seems like a
different question to me. Sorry if I am mistaken.
PDFBox doesn't create PS files itself. If ever, it's the PS printer driver who
does. Btw PDFBox doesn't create images from text, it creates vector graphics
(which gets huge).
Just to add to this, the Java printing API can put text directly into the print
output, but only for AWT fonts. We don't use AWT fonts because of buggy
rendering. Instead, we render fonts to vector paths ourselves. It is these
paths which are making the PostScript output so large.
It's certainly possible to build a PostScript converter on top of PDFBox using
our APIs, but you're not going get good results with Java's built-in AWT
PostScript driver.

Asked and answered in

Additionally, re the comment of Ken Sharp (who is a Ghostcript guy and thus has
my maximum respect): PDFBox is not a converter, it renders regardless of the
target format.
In theory, it might be possible to make a converter, by replacing all graphics
method calls with postscript commands.

Hi,
I am using PDFBox to create PDFs and that is working great. I need to take
those PDF files and produce PostScript files from them. I can do that but the
file is bloated. I am creating the content streams with compress = true. It
seems to be that the following code is producing the PS file as an image of the
page instead of extracting the text and images and coding that as a PostScript
file. Is it possible to use PDFBox to create a PostScript file with the text
in it instead of an image of the page?
This is a snippet of the code I am using to create the PostScript file:
pdfGenerator.finishFileCreation();
DocFlavor flavor = DocFlavor.SERVICE_FORMATTED.PRINTABLE;
StreamPrintServiceFactory[] factories =
StreamPrintServiceFactory.lookupStreamPrintServiceFactories(flavor,
DocFlavor.BYTE_ARRAY.POSTSCRIPT.getMimeType());
if (factories.length == 0) {
throw new PrinterException("No PostScript factories
available");
}
PDDocument document = pdfGenerator.getDocument();
PrintRequestAttributeSet aset = new
HashPrintRequestAttributeSet();
aset.add(MediaSizeName.NA_LETTER);
// aset.add(Sides.DUPLEX);
DocAttributeSet daset = new HashDocAttributeSet();
// daset.add(Compression.GZIP);
FileOutputStream fos = new FileOutputStream(filePathAndName);
Map<Integer, String> pageLayoutMap =
pdfGenerator.getPageLayoutMap();
for (int i = 1; i <= document.getNumberOfPages(); i++) {
aset.add(new PageRanges(i, i));
if
(pageLayoutMap.get(i).equals(PDFGenerator.ORIENTATION_LANDSCAPE)) {
aset.add(OrientationRequested.LANDSCAPE);
} else {
aset.add(OrientationRequested.PORTRAIT);
}
factories[0].getPrintService(fos).createPrintJob().print(
new SimpleDoc(new PDFPrintable(document,
Scaling.ACTUAL_SIZE, false), flavor, daset), aset);
}
fos.close();
document.close();
Thank you,
Ray
