ghostscript

What I am trying to do is convert a ps which is just a image to a jpg using ghostcript here is what I started with gswin32c.exe -sDEVICE=jpeg -sOutputFile="test.png" example.ps however when I run this the jpg comes out with a lot of white space to the right and the bottom Also the picture comes out huge is there any way to crop out the whitespace in ghostscript? I tried this code gswin32c.exe -sDEVICE=jpeg -dBATCH -dNOPAUSE -dSAFER -r72x72 -g200x900 -sOutputFile="test.jpg" example.ps which decrease the width but the height is still huge. Any solutions? Firstly you need to set the 'correct'

Could you please tell me how to embedded the PDF/X output intent. When I check with preflight I reported that PDF/X-1a:2001 : PDF/X output intent is missing in the PDF file.

Download latest version of ImageMagick. Unpacked it. Installing Ghostscript like this: $ sudo apt-get install ghostscript After that try to configure ImageMagick: $ ./configure --with-gslib $ make $ make install After that i try to conver PDF to jpg $ sudo /usr/local/bin/convert in.pdf out.jpg And i see this mistake convert: no decode delegate for this image format `/tmp/magick-BzHdr4Kp-00000001' @ error/constitute.c/ReadImage/544. convert: Postscript delegate failed `in.PDF': Нет такого файла или каталога @ error/pdf.c/ReadPDFImage/678. convert: no images defined `out.jpg' @ error/convert.c

i am using the ghostscriptsharp wrapper for c# and ghostscript. I want to generate thumbnails out of pdf-files. Further Information on the sample-code are given here . There are different Methods imported form the ghostscript-c-dll "gsdll32.dll". [DllImport("gsdll32.dll", EntryPoint = "gsapi_new_instance")] private static extern int CreateAPIInstance(out IntPtr pinstance, IntPtr caller_handle); [DllImport("gsdll32.dll", EntryPoint = "gsapi_init_with_args")] private static extern int InitAPI(IntPtr instance, int argc, IntPtr argv); //...and so on I am using the GhostscriptWrapper for generating

I am writing a program that uses OCR (tessnet2) to scan an image file and extract certain information. This was easy before I found out that I was going to be scanning attachments of PDFs from an Exchange server. The first problem I am working on is how to convert my PDFs to BMP files. From what I can tell so far of TessNet2, it can only read in image files - specifically BMP. So I am now tasked with converting a PDF of indeterminate size (2 - 15 pages) to BMP image. After that is done I can easily scan each image using the code I have built already with TessNet2. I have seen things using

I have two 36" by 48" posters (LaTeX) that I want to append into a single 72" by 48" poster (stack vertically). Browsing around SO and GS documentation, I have no clue (I'm not a CLI wizard). How can I do this? (Also, the process should not compress the raster images lossily, because this will be printed 2400*1200 DPI.) Since the OP didn't provide (a link to) the original input posters, this answer will proceed in three steps: Create 2 dummy posters as input for step 3 Create a LaTeX document which embeds the 2 dummy posters Run pdflatex to create a PDF from the LaTeX document in step 2 Step 1

I am converting an RGB PDF to CMYK using the following command: /usr/local/bin/gs -dSAFER -dBATCH -dNOPAUSE -dNOCACHE -sDEVICE=pdfwrite \ -sColorConversionStrategy=CMYK -sColorConversionStrategyForImages=CMYK \ -dProcessColorModel=/DeviceCMYK -dEncodeColorImages=false \ -dEncodeGrayImages=false -dEncodeMonoImages=false -sOutputFile=CMYK.PDF RGB.PDF The resulting file is 100% CMYK, however anything that was 100% black in the RGB PDF is now: C: 72% M: 68% Y: 67% K: 89% The result is that black is a slightly dark grey when really it should be black. Is there anything I need to add to this command
