ghostscript

问题 OK... It's me again. Same project. I'm trying to loop through files in a directory and set the page size on all the PDFs. I'm having difficulty getting the file names in the parameters I need to pass them through ghostscript. I gave up on changing the parameters IN the .run shell command and decided to create the parameters in a variable (as you can see). My problem seems to be in the strParam variable that I am passing. It looks correct when I check it in the msgbox but when the script runs

问题 I'm trying to hack-up a program to read a pbm, pgm, or ppm file and render the image to the postscript output device using the image operator. Just testing the P4 input (binary portable (1-bit) bitmap) path, but my output is all screwy. %! % cf. http://en.wikipedia.org/wiki/Netpbm_format % cf. http://en.wikipedia.org/wiki/Computer_Graphics (origin of image) % $ wget http://upload.wikimedia.org/wikipedia/commons/thumb/2/23/Spacewar%21-PDP-1-20070512.jpg/320px-Spacewar%21-PDP-1-20070512.jpg % $

问题 We are using following shell script to convert pdf attachment in tiff but having some issue with quality, So can you please check below shell script and let us know anything where we can improve quality as well as compress file size too as much as possible while conversation. shell_exec('/usr/bin/gs -q -sDEVICE=tiffg4 -r204x392 -dBATCH -dPDFFitPage -dNOPAUSE -sOutputFile=america_out7.tif america_test.pdf'); We have tried following command and seems quality is better but when we are going to

问题 Recently I found myself having to launch the ghostscript command from java, in both linux and windows environments, with whitespaces in input/output filenames. An example of the command follows: gs -q -dNOPAUSE -dBATCH -sDEVICE=pnggray -r300 -sOutputFile=/home/nic/tomcat/6.0.33 with spaces/temp/Thread-11/img-%03d.png /home/nic/tomcat/6.0.33 with spaces/temp/tmpfile.tmp The gs gets replaced by gswin32 on windows, given that ghostscript is in the Path. I quickly realized that I had to escape

问题 I'm trying to convert an RGB-pdf file created by Inkscape to a print ready cmyk-pdf using PSOcoated_v3.icc color profile. PDF generation works fine. However, I'd like to check for correct final colors, especially for the black. As I did not found any (free) tool to pick the cmyk color from the final pdf I thought as a first check I convert the RGB-pdf to cmyk-tiff and check the black value. Doing so using gs -q -dBATCH -dSAFER -dNOPAUSE \ -sDEVICE=tiff32nc \ -sDefaultRGBProfile=sRGB2014.icc \

问题 Example: Create a one sheet landscape PDF from Excel. Open it using Adobe Reader, where it opens as landscape. Print it using Ghostscript. Open printout using Adobe Reader, and it should still be landscape, but it isn't. This issues happens whether or not the source is a PDF or Excel itself. I use a PDF source in the example because I figured that it would be easier to illustrate the issue. I know it can probably be forced to be printed using landscape. What I don't understand is why

问题 I have a pdf with something like presentations slides and multiple slides per page. How can I use ghostscript to split the file so that there is one slide per page? 回答1: A long time ago I wrote some code for someone on comp.lang.postscript to do this, again it was for PowerPoint slides. This PostScript code assumes that all the 'subpages' (ie slides) are the same size and location on the PDF page and that all the PDF pages are the same size. Save the following as a file called pdf_slice.ps

问题 Currently I'm using this command to generate the SVG: gs -sDEVICE=svg -dNOCACHE -sOutputFile="photo.svg" -q -dbatch -dNOPAUSE "photo.pdf.out" -c quit I'd like to double the size of the image. Using GS's -r and -g options just gives me the same image. I'm not sure these options are supported within GS with the SVG device. I've tried using ImageMagick's convert to bypass ghostscript but when I go to see the image in a browser it displays the SVG as code. The original image is a cropped PDF. I
