I'm trying to use ImageMagick to convert a bunch of PDF into JPG (or PNG) but this error keep happenings.
convert E/paginas/pdf/E2.pdf E/paginas/pdf/E2.png
convert: no decode delegate for this image format `/tmp/magick-qX48YuZM-00000001' # error/constitute.c/ReadImage/532.
convert: Postscript delegate failed `E/paginas/pdf/E2.pdf': # error/pdf.c/ReadPDFImage/663.
convert: missing an image filename `E/paginas/pdf/E2.png' # error/convert.c/ConvertImageCommand/3015.
Same to .jpg
PS: I'm at Ubuntu 10.10
ImageMagick 6.6.0-4 just successfully converted a PDF-1.4 file to .png format. What version are the PDFs you're using, and what version of convert?
You determine the PDF version with: head -c 8 myfile.pdf
The ImageMagick version: convert --version
What you can do to diagnose the problem is to apt-get source imagemagick, and use the source line numbers in the error messages to locate the problem, and possibly fix the program to recognize the PDF, even if you have to tell the program to ignore certain sections.

I recently changed my server to Ubuntu 18.04 and now I have an error with paperclip and imagemagick. File uploads work locally but not on my server. I am running rails 5.2.3 and paperclip 5.2.1 and ImageMagick 7.0.8-56. I added the following line to environments/production.rb:
Paperclip.options[:command_path] = '/usr/local/bin/'
but still get the error. When I run identify -list format to see what files Imagemagick works with, it does not say jpg, which is different than my old server. Here is the partial output:
ICON* rw- Microsoft icon
IIQ r-- Phase One Raw Image Format
INFO -w+ The image format and characteristics
INLINE* rw+ Base64-encoded inline images
IPL* rw+ IPL Image Sequence
ISOBRL* -w- ISO/TR 11548-1 format
ISOBRL6* -w- ISO/TR 11548-1 format 6dot
JNX* r-- Garmin tile format
JSON -w+ The image format and characteristics
K* rw+ Raw black samples
K25 r-- Kodak Digital Camera Raw Image Format
KDC r-- Kodak Digital Camera Raw Image Format
LABEL* r-- Image label
The error I get is Paperclip::Errors::NotIdentifiedByImageMagickError in my production log when I upload an image.
Some files were apparently not installed because I installed imagemagick from source. I had to hard delete the folder with imagemagick in it and reinstall using sudo apt-get install imagemagick libmagickcore-dev libmagickwand-dev . Thank you.
I explored Perl2Exe, PAR, PAR::Packer to convert perl script to a exe. I am unable to convert via either of the options below, Kindly can you let know what needs to be done.

I am trying to convert an image in EMF format to PNG using Imagemagick on Red Hat Enterprise Linux Server release 5.5 (Tikanga), but I am running into the following error:
convert: no decode delegate for this image format `thumbnail.emf' # error/constitute.c/ReadImage/550.
convert: no images defined `1.png' # error/convert.c/ConvertImageCommand/3068.
How might I fix this?
Install libreoffice and run this command on the folder where your emf files are located:
libreoffice --headless --convert-to png *.emf
Another way is to use inkscape:
inkscape -o file.png source.emf
See inkscape --help for more export options (area to export, dpi, image resolution, background color etc).
According to this page: http://www.imagemagick.org/script/formats.php
EMF R Microsoft Enhanced Metafile (32-bit) Only available under Microsoft Windows.
I have problem with rmagick in Rails 3.
Everything seems to be installed, but I get the following error:
Failed to manipulate with rmagick, maybe it is not an image? Original
Error: unable to open image
`kar/public/uploads/tmp/20110825-1348-30304-9150/thumb_1314198312_by_jannnu11_500.jpg':
# error/blob.c/OpenBlob/2588
File exists. Have good chmod.
This code works on another server.
Any ideas?
In some cases the installation of ImageMagick may have missed some of the file formats required for the image manipulation you are trying to do on that machine.
Try to run identify -list format and see what you are missing from there.
If it turns out that you are just missing the file format, try to uninstall/reinstall and you should be good to go.
When I try to upload a photo in Ruby on Rails using Paperclip on my local machine it works perfectly.
When I try to upload a photo in Ruby on Rails using Paperclip on our Linux (CentOS 5.2) server with Apache and Phusion Passenger, I get:
2 errors prohibited this user from being saved
There were problems with the following fields:
- Avatar /tmp/stream20091026-21120-1qdbnul-0 is not recognized by the 'identify' command.
- Avatar /tmp/stream20091026-21120-1qdbnul-0 is not recognized by the 'identify' command.
I tried adding:
Paperclip.options[:command_path] = "/usr/local/bin"
to production.rb but it didn't make a difference.
In the log files I get the following errors:
Parameters: {"commit"=>"Upload",
"action"=>"update", "_method"=>"put",
"authenticity_token"=>"419410afc22737cd2f6b6096a95327db76a48ba9",
"controller"=>"users",
"user"=>{"avatar"=>#}}
[paperclip] Saving attachments.
[paperclip] An error was received
while processing:
/tmp/stream20091026-20752-1g568yk-0 is
not recognized by the 'identify'
command.
Identify is a command-line utility inside the ImageMagick package.
From its homepage:
The identify program describes the
format and characteristics of one or
more image files. It also reports if
an image is incomplete or corrupt. The
information returned includes the
image number, the file name, the width
and height of the image, whether the
image is colormapped or not, the
number of colors in the image, the
number of bytes in the image, the
format of the image (JPEG, PNM, etc.),
and finally the number of seconds it
took to read and process the image.
Many more attributes are available
with the verbose option.
First, copy the image on the server and run the identify command on it. You should receive something like:
identify ~/capture.jpg
capture.jpg JPEG 1216x244 1216x244+0+0 8-bit DirectClass 97.7kb
If you receive an error, try upgrading the ImageMagick package on your server. You may find an updated binary release here:
http://www.imagemagick.org/script/binary-releases.php
in my case with same error, reinstalling imagemagic helped out (ubuntu 12.10)
