I am trying to generate tiff file using ghost script from a pdf.
I am using this command
gs -dSAFER -dBATCH -dNOPAUSE -dFirstPage=2 -dLastPage=2 -r450x635 -sDEVICE=tiffgray -sCompression=lzw -sOutputFile=test2_local.tif foil.pdf
The tiff file is getting generated but it is not opening and i am getting message of damaged file. If I reduce resolution then it works fine. And it also works if remove the compression.
But i can not remove compression as file size generated is 174MB. I am using GS 9.22 on mac OS.

I'm trying to convert some PDFs to jpegs using imagemagick . I'm working on win 10, 64 with python 3.62 - 64 bit and wand 0.4.4. I've been able to get wand working with ImageMagick-6.9.9-Q16-HDRI. I have all this set up on a E USB flash drive. I've set both the Path and MAGICK_HOME env vars to
E:\ImageMagick-6.9.9-Q16-HDR;E:\gs\bin
Originally I installed ghostscript 9.22 - 64 at E:/gs9.22 , but the I read ( PythonMagick can't find my pdf files) that 64 bit may not work so I deleted that and got ghostscript 9.22 - 32 bit, which I installed as above.
I ran:
$ convert myfile.pdf test.jpg
convert.exe: FailedToExecuteCommand `"E:/gs9.22/bin/gswin64c.exe" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=png

convert.exe: no images defined `test.jpg' # error/convert.c/ConvertImageCommand/3258.
Why is the system looking for the 64 bit ghostscript path (which I deleted) ? I have closed and reopened my editor and the environmental var editor.
I ended up using the regedit utility to manually go through and remove all traces of 'ImageMagick'. The included uninstall utility in Imagemagick did not remove everything. After this I was able to install new versions.
I am using Ghostscript on Windows 7 machine to convert PDF to PNG. My input PDF has many pages but the PNG file only contain the first page !
I am using the following command line:
gswin64c -sDEVICE=png16m -r720x720 -dNOPAUSE -dBATCH -sOutputFile=79245340005_1602.png 79245340005_1602.pdf
and the logfile is as follow:
GPL Ghostscript 9.20 (2016-09-26)
Copyright (C) 2016 Artifex Software, Inc. All rights reserved.
This software comes with NO WARRANTY: see the file PUBLIC for details.
Processing pages 1 through 2.
Page 1
Page 2
As you can see, it seems that both pages are processed but only the first one appear in the final PNG file. Any idea what is wrong in my command line ? I try to look a the documentation but didn't find what I am doing wrong. If I have a single PDF file with 10 pages, I wand a single output PNG file with 10 pages.
My original command line was as follow but had the same issue:
gswin64c -q -sPAPERSIZE=a4 -sDEVICE=png16m -dTextAlphaBits=4 -r720x720 -o 79245340005_1602.png -dNOPAUSE -dBATCH 79245340005_1602.pdf
Thanks

PNG can hold only one image per file. Use TIFF or the like for multiple images per file.
Try to use following syntax to achieve rasterizing into several png's
gswin64c -q -sPAPERSIZE=a4 -sDEVICE=png16m -dTextAlphaBits=4 -r720x720 -o -sOutputFile='79245340005_1602_%00d.png' -dNOPAUSE -dBATCH 79245340005_1602.pdf
I've read a number of post and tried to follow but it's not working.
Using GS (gsdll32.dll) with the following arguments:

Without any cropping logic I get the image on an 8.5 x 11, with cropping(above commands) the objects are translated mostly off the top of the page and do not seem to move to the left.
The size of the result image is correct.
Does anyone see anything wrong?
Thanks
You've put the /Install after the input file, that means it will be executed after the input file is complete. Which means it takes effect after the input is completely processed, which is too late to have nay effect.
Order of switches, and particularly order of input, is important in Ghostscript.
That's assuming that 'AI2PNG' is a synonym for Ghostscript.
When I run the following command to convert a PDF to Image using ImageMagic Convert util with the following parameters :
C:\Windows\system32>"C:\Program Files\ImageMagick-6.5.8-Q16\convert.exe" "D:\RealDocs.pptx.pdf" "d:\hello.jpg"
I get the following error :
convert.exe: `%s': %s "gswin32c.exe" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dEPSCrop -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pnmraw" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" "-sOutputFile=C:/Users/Nupitch/AppData/Local/Temp/magick-xwOF7jbV" "-fC:/Users/Nupitch/AppData/Local/Temp/magick-BescEsek" "-fC:/Users/Nupitch/AppData/Local/Temp/magick-XfLll9WM" # utility.c/SystemCommand/1964.convert.exe: Postscript delegate failed `D:\RealDocs.pptx.pdf': No such file ordirectory # pdf.c/ReadPDFImage/634.convert.exe: missing an image filename `d:\hello.jpg' # convert.c/ConvertImageCommand/2838.
please help me ~
ImageMagick cannot handle PostScript and PDF files itself and by its own. For this it uses a third party software called Ghostscript as a 'delegate'.
Has your Windows system Ghostscript installed properly? Or is not installed at all?
Try to download and install the latest version from here.
Probably you'd get a different error message if the problem is caused by a missing Ghostscript installation. But your error is:
D:\RealDocs.pptx.pdf': No such file or directory
# pdf.c/ReadPDFImage/634.convert.exe: missing an image filename `d:\hello.jpg'
This could mean that the user account you run this command under does not have permission to write to the root of the D: drive.
To test this, you could run the conversion command in a cmd.exe window in a slightly modified way:
"C:\Program Files\ImageMagick-6.5.8-Q16\convert.exe" ^
"D:\RealDocs.pptx.pdf" ^
"%userprofile%\hello.jpg"
(On Windows XP, %userprofile% usually points to c:\documents and settings\<your username>\...)
I am using Ghostscript9.0, I try to generate a LZW TIFF images with 24 bit depth from pdf file, I always get bit depth = 1 using this GS command:
gswin32.exe -dSAFER -dBATCH -dNOPAUSE -r200 -sDEVICE=tifflzw -sOutputFile=tmp.tiff myfile.pdf
I searched in several manuals:
http://ghostscript.com/doc/current/Devices.htm
http://www.ghostscript.com/doc/8.54/Use.htm
but I didn't find anything of parameters to do that.
I add an image example proporties that I would like to produce with gs:
Here we can see the bit depth (profondeur de couleur) = 24 and the image is compressed with LZW
It is clearly stated that the format tifflzw you have chosen is located in the section
The remaining TIFF drivers all
produce black-and-white output with
different compression modes
http://ghostscript.com/doc/current/Devices.htm
If you want a 24bit output you have to use tiff24nc instead and add specify the compression via the parameter -sCompression=lzw
gswin32.exe -dSAFER -dBATCH -dNOPAUSE -r200 -sDEVICE=tiff24nc -sCompression=lzw -sOutputFile=tmp.tiff myfile.pdf
