Including PostScript in PDFBox
Hi,
is it possible to include PostScript images on a PDPage in PDFBox?
Many thanks.
Philippe

Keep the jpeg at the original size, and use the drawXImage method to
resize. Use the PDJpeg constructor that uses a stream, not the one that
uses a BufferedImage.

Philippe,
It would be better to export a PDF rather than an EPS, if the software you’re using supports that, because PDFBox can easily add existing PDFs to a page as graphics.
Converting an EPS to a PNG isn’t a great idea because you’re converting vector graphics into raster graphics, but PDF is a vector format, so you’re really loosing the advantage of using PDF, i.e. vector graphics will never be pixelated.

Hi John,
I have exported an EPS image to a 2000 DPI PNG using Inkscape,converted the PNG to a 100%-quality JPG using Gimp, and then added the JPG image as a 300 x 27 pixel PDJpeg to a PDPage. Yet, the JDJpeg is pixelated.
Is there a better way to make PDPjeg images as little pixelated as possible?
Cheers,
Philippe

Hi Philippe,
PDFBox cannot do that directly. For simple PostScript files you might be able to parse the files yourself and convert the drawing commands into equivalent PDF commands. However, for any non-trivial file you’re going to need a PostScript interpreter.
If you don’t need to be 100% Java then an alternative route would be to convert your PostScript to PDF using Ghostscript and then you can use PDFBox to include that PDF image on a page.
