ghostscript

please bear with my newbie questions.. I was trying to convert PDF to PNG using ghostscript, with ASP.NET and C#. However, I also read that ghostscript is not thread safe. So my questions are: What exactly does "ghostscript is not thread safe" mean in practical terms? What impact does it have if I use it in a live ASP.NET(aspx) web application with many concurrent users accessing it at the same time? I also read from another site that the major feature of ghostscript ver. 8.63 is multithreaded rendering. Does this mean our thread safe issue is now resolved? Is ghostscript thread safe now? I am

When i want to use ghost4j on OS X 10.9, i see this error: Unable to load library 'gs': dlopen(libgs.dylib, 9): image not found I have installed ghostscript library on my macbook using this site . how can i fix this problem. I can not install ghostscript using port and brew for some reason. First you need to find the file libgs.dylib which was installed by the installer package compile the libgs.dylib library from source, and make a note of where you installed it to. Hopefully it should have been installed to a standard library location, and there should be nothing more you need to do. If not,

I'm having troubles with ghostscript 9.10 apparently removing content outside of the crop box (specifically the crop marks I've put there) This is the PDF before using ghostscript: with_cropbox_before_optimize.pdf $ pdfinfo -box with_cropbox_before_optimize.pdf MediaBox: 0.00 0.00 651.97 898.58 CropBox: 28.35 28.35 623.62 870.24 Setting the viewer to display the entire media box shows the crop marks outside of the crop box as expected. (the black border is there to illustrate where the crop box would be) Then I'm calling: gs -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -dCompatibilityLevel=1.7 \

I am trying to generate a PDF using a library called wkhtmltopdf to create an RGB pdf. I am then using ghostscript to convert it to a CMYK format, however, the black text that is in the pdf is not pure black [cmyk(0,0,0,1)]. The black color is visible in other channels. The command for ghostscript is: gs -dBATCH -dNoOutputFonts -dNOPAUSE -dTextBlackPt=1 -dBlackPtComp=1 -sTextICCProfile -dNOCACHE -sDEVICE=pdfwrite -sProcessColorModel=DeviceCMYK -sColorConversionStrategy=CMYK -sOutputICCProfile=ps_cmyk.icc -sDefaultRGBProfile=srgb.icc -dOverrideICC=true -dRenderIntent=1 -sOutputFile=cmyk11.pdf

Is it possible to create a tiff file from a postscript-file (created from a pdf-document with readable text and images) into a tiff file without the images and only the text? Like add a maxbuffer so images will be removed and only text remaining? And if boxes and lines around text could be removed as well that would be awesome. Best regards! KenS You can redefine the various 'image' operators so that they don't do anything: /image { type /dicttype eq not { % uses up argument, only one if dict form pop pop pop pop % remove the arguments for the non-dictionary form. } ifelse } bind def
