How to user GhostScript DLL to convert PDF to PDF/A. I know I kind of have to call the exported function of gsdll32.dll whose name is gsapi_init_with_args, but how do i pass the right arguments? BTW, i'm using C#. serge_gubenko pls, try to run this from the command line to test if it's doing what you need. gswin32.exe -dPDFA -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=PDFA.pdf 1.pdf A Simple C# Wrapper for Ghostscript I've had it working using the following from ghostscriptsharp : [DllImport("gsdll32.dll", EntryPoint = "gsapi_new_instance")] private static extern int CreateAPIInstance(out

I already know about Ghostscript front end viewers; but I was wondering how gs itself could be used for viewing PDF documents? The closest I could get to, is to specify explicitly x11 window as output device, specify width and height of the window via -g , and specify rasterization resolution via -r ; or, a command line like this: gs -sDevice=x11 -g500x500 -r150x150 -dFirstPage=3 fontspec.pdf ... which results with something like: ... which is, in fact, all good - except, it starts at lower left corner; and there are no keyboard shortcuts (as far as I can see) here to move the viewport, or to

I need to convert a PDF to JPEG (or any other image format as PNG...) with C# I have the path to the PDF and I want to obtain a MemoryStream of the image. I managed to do it with Ghostscript and GhostscriptSharp but I'm forced to create a file, the actual image, and then read this file to create the MemoryStream. Can I do it without this step? Thanks Yes, but you will need to interface directly to Ghostscript using the Ghostscript DLL (I'm assuming Windows since you mention C#). The simplest solution is probably to use the display device which sends an in-memory bitmap back to the parent

I need to generate JPEG's from PDF. JPEG must be created based on Trim Box and PDF's can be version 1.3 with extra Pantone colors that absolutely require Overprint Preview so only GhostScript (and Rip's of course can handle them). Both Photoshop, Image Magick and SIPS (Scriptable Image Processing System of OS X) cannot solve both problems (Crop to trim and composite handling overprint). I created an app to rasterize the PDF I receive and all works good EXCEPT that some chinese PDF have one font not embedded. This font is Chinese STXiHei TrueType (CID) with encoding G8pc-EUC-H (info extracted

I'm using Imagemagick to create thumbnails images of pdf files with this command: convert 'input.pdf[0]' -resize "100x140>" -colorspace 'rgb' 'output.jpg' 2>/dev/null Some of the PDFs are in CMYK color space, hence the specification of the expected -colorspace as rgb. This was working fine until I updated to the latest versions of Imagemagick(6.6.7-1) and ghostscript(9.01_0), now it looks like the conversion to rgb isn't working any longer, here is an example output: (The background should be white, not black) It seems though that the problem comes from the -resize option because if I remove

in my current software I'm creating pdf-files and printing them out with ghostscript like this: ... string[] printParams = new string[] { "-q", "-sDEVICE=mswinpr2", "-sPAPERSIZE=a4", "-dNOPAUSE", "-dNoCancel", "-dBATCH", "-dDuplex", string.Format(@"-sOutputFile=""\\spool\{0}""", printerName), string.Format(@"""{0}""", filename) ... var p = new Process(); p.StartInfo.FileName = this.ghostScriptExePath; p.StartInfo.Arguments = string.Join(" ", printParams); p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; p.Start(); ... So far it works just fine and prints out on the specified printer. My

I have implemented the following save function in my program which allows the user to save as a JPEG file whatever he/she draws on the Tkinter canvas with the Turtle. How it is supposed to work is that it first captures the screen and Tkinter canvas and then creates a postscript file based on it. Then it converts that postscript file as a PIL (Python Imaging Library) readable file type, and then the PIL saves the converted file as a JPEG. My save function is shown below: def savefirst(): # Capture screen and Tkinter canvas cnv = getscreen().getcanvas() global hen # Save screen and canvas as
