ghostscript

Is it possible to get the page size (from e.g. a PDF document page) using GhostScript? I have seen the "bbox" device, but it returns the bounding box (it differs per page), not the TrimBox (or CropBox) of the PDF pages. (See http://www.prepressure.com/pdf/basics/page_boxes for info about page boxes.) Any other possibility? Meanwhile I found a different method. This one uses Ghostscript only (just as you required). No need for additional third party utilities. This method uses a little helper program, written in PostScript, shipping with the source code of Ghostscript. Look in the toolbin

I would like to know a way to remove white margins from a PDF file. Just like Adobe Acrobat X Pro does. I understand it will not work with every PDF file. I would guess that the way to do it, is by getting the text margins, then cropping out of that margins. PyPdf is preferred. iText finds text margins based on this code: public void addMarginRectangle(String src, String dest) throws IOException, DocumentException { PdfReader reader = new PdfReader(src); PdfReaderContentParser parser = new PdfReaderContentParser(reader); PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(RESULT))

Is there a way to use ghostscript to convert PDF to PDF/A or PDF/X? I know it can be used to convert PDF to images, but I don't know if it can be used to convert PDF/A. What parameters should I use? This is to convert a pdf document (not pdf/a) into pdf/a: gs -dPDFA -dBATCH -dNOPAUSE -dUseCIEColor -sProcessColorModel=DeviceCMYK -sDEVICE=pdfwrite -sPDFACompatibilityPolicy=1 -sOutputFile=output_filename.pdf input_filename.pdf Hope this will help some one! @danio, @imgen: Even recently released documentation pages on PDF/X (standardized Prepress requirements) and PDF/A (standardized Archiving

I want to remove all images from a PDF file. The page layouts should not change. All images should be replaced by empty space. How can this be achieved with the help of Ghostscript and the appropriate PostScript code? Meanwhile the latest Ghostscript releases have a much nicer and easier to use method of removing all images from a PDF. The parameter to add to the command line is -dFILTERIMAGE gs -o noimages.pdf -sDEVICE=pdfwrite -dFILTERIMAGE input.pdf Even better, you can also remove all text or all vector drawing elements from a PDF by specifying -dFILTERTEXT or -dFILTERVECTOR . Of course,
