I have PDFs that I need to convert to images. I have installed Imagemagick. I have a PDF named a.pdf that I can open (it is not corrupt) in the folder C:\Convert\
From the command line I am trying
C:\Convert>convert a.pdf a.jpg
And I am getting the error.
convert.exe: FailedToExecuteCommand `"gswin32c.exe" -q -dQUIET -dSAFER -dBATCH -

UPDATE:
After the SO community helped me solve this issue I put together a little tool to batch convert images. Hope it helps somebody.

You need to install Ghostscript in order to rasterize vector files (PDF, EPS, PS, etc.) with ImageMagick. IM will shell out to Ghostscript when doing these manipulations (you can see it if you use the -verbose tag in your IM invocation). You could also use Ghostscript by itself to rasterize vector files.
Since you actually have to install Ghostscript to do this, why not drop ImageMagick all-together? It just forwards the command to Ghostscript anyway, not adding any value, just taking way longer to process (and loading everything into RAM while its at it).
Install GhostScript and run the command:
gswin64c.exe -dNOPAUSE -sDEVICE=jpeg -r200 -dJPEGQ=60 -sOutputFile=foo-%03d.jpg foo.pdf -dBATCH
This is identical and faster than running:
convert -quality 60 -density 200 foo.pdf foo-%03d.jpg
It's in the docs now. https://github.com/dlemstra/Magick.NET/blob/main/docs/ConvertPDF.md
You need to install the latest version of GhostScript before you can convert a pdf using Magick.NET.
Make sure you only install the version of GhostScript with the same
platform. If you use the 64-bit version of Magick.NET you should also
install the 64-bit version of Ghostscript. You can use the 32-bit
version together with the 64-version but you will get a better
performance if you keep the platforms the same.
Here is a wrapper: https://archive.codeplex.com/?p=ghostscriptnet
I found that I had installed GhostScript, but GhostScript was not able to execute because it needed additional libraries. By typing "gs" on a command line, I was able to see what libraries were missing.
Install GhostScript GNU Affero General Public License from here.

I am testing my file conversions on the test server and I got this error below. I tested the case on my local and it worked without a problem. On the server it gives me some trouble.
FailedToExecuteCommand `"gswin32c.exe" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pngalpha" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -g350x350 -dEPSCrop "-sOutputFile=C:/Windows/TEMP/magick-1520z9_ZtBD3O2dg%d" "-fC:/Windows/TEMP/magick-15203XcyD8hja0LJ" "-fC:/Windows/TEMP/magick-1520fnhOiV0JVLNJ"' (Le fichier spécifié est introuvable.) # error/delegate.c/ExternalDelegateCommand/475.convert:
Any help/tips would be greatly appreciated.
EDIT 2:
I also find a link where the imagemagick admin suggests to change the gs path in the delegates.xml. This solution looks promising but the delegate file has one entry for eps to ps conversions as below:
<delegate decode="eps" encode="ps" mode="bi" command=""#PSDelegate#" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 -sDEVICE=ps2write "-sOutputFile=%o" -- "%i""/>
And I can't seem to find how imagemagick refers to the GS location. I added gs to the path variable and/or modified the delegates.xml with the location to fix this.
EDIT 3:
I have a error "no images defined" from the imagemagick convert command as below. Do I need to set up some permissions for gs because I don't find the temporary folders in the Temp directory.These seems to work magically on my local, but hesitates to function on the test server.

For the first problem,
FailedToExecuteCommand `"gswin32c.exe"
Configure the path of the ghostscript bin folder on the system variables and/or configure the delegates.xml which can be found in the folder path C:\Program Files\ImageMagick-7.0.8-Q16
Modify the delegate as below:
delegate decode="eps" encode="ps" mode="bi" command=""C:\Program
Files\gs\gs9.26\bin\gswin64.exe#" -q -dQUIET -dSAFER -dBATCH
-dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 -sDEVICE=ps2write "-sOutputFile=%o" -- "%i""
For the second problem where Imagemagick has problems to access the Temp folder of the C drive.
Add or uncomment the policy for the temporary file path as below
policy domain="resource" name="temporary-path"
value="D:/inetpub/IndependenceAWS/Conversion-Temp"/
Another edit in the same xml as below solves the problems and allows imagemagick to use the new folder for temporary conversions
policy domain="module" rights="read|write" pattern="{PS,PDF,XPS}"
A great thanks to all the people who have commented on my question and helped me solve these issues.
You need to install ghostscript.
You can download it here and install it and the error goes away.
For example, download the 64bit version, and double click it and go by its installation instructions. Then rerun your magick command, the FailedToExecuteCommand "gswin32c.exe" error will go away.
Note: as a comment mentioned: GS 9.26 has some bugs -- try downgrading to 9.23, 9.24 or 9.25. 3, using 9.27 produces neither errors nor output, but after changing to 9.24, all things are fine.
If anyone is having this issue with the MSYS2 build of ImageMagick, you need to install GhostScript through MSYS2: run either of:
on MSYS2 MinGW 64 bits: pacman -S mingw-w64-x86_64-ghostscript
on MSYS2 MinGW 32 bits: pacman -S mingw-w64-i686-ghostscript
Changed gs to full path.
Problem is here....
I know this is an old thread but I'd like to add my experience as it may help someone.
I was getting the same error as you, but for me the issue turned out to be not enough RAM.
This was running on a VM with not much RAM allocated, upgraded to 4GB and everything works great.
I am using following environment:
Ubunut : 11.0 (virtual machine)
Imagemagick : ImageMagick-6.9.3-7
I have execut following command:
wget http://www.imagemagick.org/download/ImageMagick.tar.gz
tar xzvf ImageMagick.tar.gz
ls
cd ImageMagick<version number here>/
./configure
make clean
make
sudo make install
ldconfig /usr/local/lib
After executing below command:
make check
40 test case 39 pass only 1 is fail (FAIL: tests/wandtest.tap 1)
Now i want to convert pdf file to jpg via command:
convert test.pdf test.jpg
convert: no decode delegate for this image format PNG' # error/constitute.c/ReadImage/501.
convert: no images definedtest.jpg' # error/convert.c/ConvertImageCommand/3252
convert test.pdf test.png
convert: no decode delegate for this image format PNG' # error/constitute.c/ReadImage/501.
convert: no images definedtest.png' # error/convert.c/ConvertImageCommand/3252.
anyone can suggest me how can i do ?
ImageMagick uses assorted external libraries to do its dirty work as far as input and output handling goes for various formats. In your case:
For reading PDFs, you need to have Ghostscript installed. Also it needs to be in your path as gs in order to work, so don't use that for some other shell alias. For more details see: https://superuser.com/q/819277/33767
For writing PNGs you'll need libpng.
Once those things are on your system (and in the case you compiled IM yourself, on your system at the time of compile) you should be golden.
It may be that the issue is not with the writing but with the reading of the PDF itself.
Check the ImageMagick policy.xml.
sudo nano /etc/ImageMagick-6/policy.xml
Find the PDF and change to this:
<policy domain="coder" rights="read|write" pattern="PDF" />
This solved for me.
Same problem. Solved it with:
apt-get -y install ghostscript
I want to convert all my PNGs to PNG using ImageMagick (I need this because AndroidStudio has some issue with the original PNGs. ImageMagick is able to fix this issue by re-exporting the PNG.)
If I do: convert a.png a.png it works.
But how do I do this for many files (including files from sub directories)?
For Windows users -- you can try this in a cmd.exe window:
for %i in (*.png *\*.png *\*\*.png *\*\*\*.png) do (
convert.exe %i %~pni---repaired.png
)
This will loop through the current dir's PNGs as well as the ones in the sub directories 3 levels deep.
You have to make sure that your convert.exe really is the one from ImageMagick -- set up your environment variable %PATH% accordingly. Otherwise you may run into an error when the command wants to use the identically named disk format conversion convert.exe command.
If unsure, use the full path to the IM convert.exe, e.g.:
D:\programs\imagemagick-install-dir\convert.exe %i %~pni---repaired.png
Also, remember: If you put the above command into a *.bat file, you have to double up each occurrence of %. So %i from the direct command becomes %%i in the batch file!
If you are on Vista/Windows7/2008/8 (or on Windows XP with the Resource Kit installed) you'll have the ForFiles.exe available, which can be used to loop through files:
forfiles.exe ^
/p <path> ^
/m *.png ^
/s ^
/C "convert.exe #file #fname---repaired.png"
Try this command. Start it from the top-most directory from where you want to convert all images:
find . -name "*.png" \
| while read image; do \
convert "${image}" "${image/.png/---repaired.png}
done
Caveats: Should you have PNG files with the suffix .PNG or .pNg or similar, the command will not work for these. For such cases, the command needs some modifications...
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/ConvertImageCommand/3044.
What i'm doing wrong?
Try the following convert commands to see more precisely what's possibly going wrong:
convert a.pdf -debug coder a.jpg
convert a.pdf -debug all a.jpg
There will possibly be a lot of output going to stderr. Amongst the lines you may see where IM is looking for Ghostscript. Also, try
convert -list delegate
convert -list delegate | grep --color -E '(eps|pdf)'
to find with which exact commandlines ImageMagick tries to run Ghostscript (it may call gsx instead of gs, or it may look for it in /usr/local/bin/...). If you find any deviations from your real Ghostscript installation, you can possibly fix it by editing delegates.xml.
convert -list configure
will show you how ImageMagick is configured (and if, for example, gs was during compile-time in the list in DELEGATES variables). Here you also find where to look for delegates.xml:
convert -list configure | grep CONFIGURE_PATH
should list the directory where this (as well as some more) *.xml settings files are located which control how convert et al. behave...
I am generating thumbnails and medium sized images from large photos. These smaller photos are for display in an online gallery. Many of the photographers are submitting JPEG images using Adobe RGB. I have been asked if the thumbnail and medium size images can use sRGB as the images as is appear "flat" in some browsers.
I'm currently using ImageMagick to create the smaller versions. It has a -colorspace option, but that doesn't seem to do what I want.
Is there any other way to do this? Also, do you think this is worthwhile?
You can use the ImageMagic -profile option:
convert image.jpg -profile <adobe.icc> -profile <sRGB.icc> new_image.jpg
See here for more details:
http://www.imagemagick.org/Usage/formats/#color_profile.
Have you tried using Little CMS? This command will convert an image with a special color profile (i.e. Adobe RGB 1998) to one with no color profile but the same effective colors:
jpgicc -q100 input.jpg output.jpg
I'm setting JPEG quality to 100 here.
The following thread in the ImageMagick forum discusses exactly this in some detail: http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=16464
I now use this bash script to convert any picture (including CMYK) to sRGB:
http://alma.ch/scripts/any2srgb
It requires icc profiles for images which don't have embedded profiles. These can be found easily on the web. For example on Adobe's site: http://www.adobe.com/cfusion/search/index.cfm?term=icc+profile&siteSection=support%3Adownloads
Here is a summary (untested) of what the full script does (without it's resize and other options). It requires profiles and ImageMagick. On Debian-based systems: apt-get install icc-profiles imagemagick.
#!/bin/bash
srgb=sRGB.icm
cmyk=ISOwebcoated.icc
# extract possible color profile
profile="${f/%.*/.icc}"
convert "$f" "icc:$profile" 2>/dev/null
if cmp -s "$profile" "$srgb" ; then
# embedded profile is already srgb. Nothing to do
exit
fi
if [ -s "$profile" ]; then
# we have an embedded profile, so ImageMagick will use that anyway
convert "$f" -profile "$srgb" +profile '*' "$outfile"
else
# no embedded profile in source
if identify -format "%r" "$f" | grep -q CMYK; then
# CMYK file without embedded profile
convert "$f" -profile "$cmyk" -profile "$srgb" "$outfile"
fi
fi
Re-exporting the image using Krita seems to work well enough for me:
krita my_img.jpg --export --export-filename my_img_in_srgb.jpg
Krita is an open source Photoshop/Paint, with a(n extremely limited) command line interface. Install it with
sudo apt install krita
