convert wmf to jpg with graphicsmagick, unable to read font - imagemagick

I try to convert a wmf file into a jpg. gm says it is "Unable to read font (n021004l.pfb) [No such file or directory]." My command is like that:
gm convert 456.wmf 456.jpg
What could be wrong? I am using the latest gm version 1.3.29 and have ghostscript installed. OS: Windows 7
Here's the small file that I am trying to convert: https://mycloud.m-box.at/index.php/s/lBMeCG0cjK45sI1
And here's the version log (wmf is enabled):

This looks a bit odd. I would suggest you enable debugging messages and see if you can trace what is going wrong yourself.
So, use:
gm convert -debug all 456.wmf 456.jpg > debug.txt 2>&1
and then look at the last few lines in debug.txt.
Sorry I can't help further!

Why does ImageMagick fail with "no decode delegate for this image format `PNG'" even when the png delegate is installed?

I'm working on openSUSE Tumbleweed.
I have ImageMagick installed.
$ convert --version
Version: ImageMagick 7.1.0-52 Q16-HDRI x86_64 20549 https://imagemagick.org
Copyright: (C) 1999 ImageMagick Studio LLC
License: https://imagemagick.org/script/license.php
Features: Cipher DPC HDRI Modules OpenMP(4.5)
Delegates (built-in): bzlib djvu fontconfig freetype gslib jng jpeg lcms ltdl lzma png ps raw tiff x xml zlib
Compiler: gcc (12.2)
Notice that the PNG delegate is installed, at least according to --version.
Despite this, converting fails.
$ convert covalent_platform.svg covalent_platform.png
convert: no decode delegate for this image format `PNG' # error/constitute.c/ReadImage/776.
convert: no images defined `covalent_platform.png' # error/convert.c/ConvertImageCommand/3342.
Even identifying a non-PNG file fails, with the same PNG delegate problem.
$ identify covalent_platform.svg
identify: no decode delegate for this image format `PNG' # error/constitute.c/ReadImage/776.
Any ideas for what might be wrong here?
I reinstalled libpng-devel and reinstalled IM, but the problem remains.
I figured out the problem, thanks to #fmw42 pointing out that if magick -list format has no output then the installation is bad.
I had installed IM from https://imagemagick.org/script/download.php
These downloads are not compatible with openSUSE.
After uninstalling and reinstalling IM from https://software.opensuse.org/package/ImageMagick, everything works as expected.

imagemagick wmf support on Alpine Linux

I am installing imagemagick on Alpine, which picks up 7.0.10 version of imagemagick.
My primary use is to covert WMF to PNG.
But convert sample.wmf sample.png gives error
convert: no decode delegate for this image format `WMF' # error/constitute.c/ReadImage/572.
convert: no images defined `sample.png' # error/convert.c/ConvertImageCommand/3322.
As per https://www.imagemagick.org/script/formats.php, I also installed libwmf, which does not resolve the issue.
identify -list format | grep WMF does not return any result.
Updated Answer
You are in luck! GraphicsMagick can do it on alpine:latest:
apk add graphicsmagick
gm identify -version

Original Answer
I don't think you'll be able to do that, with ImageMagick at least...
I tried installing libwmf on alpine:latest and then installing ImageMagick from source and it declined to use libwmf v0.2.12
So I checked what ImageMagick requires and it wants libwmf v0.2.8.2.
So I tried alpine:3.8 which can install libwmf v0.2.8.4 but ImageMagick still wouldn't accept that (xxx/ipa.h is missing).
So I looked back to alpine:3.3 and alpine:3.4 and they have no libwmf.
So I tried alpine:3.5 and that was the same libwmf version as alpine:3.8
TLDR; alpine:3.5's libwmf is too new for ImageMagick and alpine:3.4 doesn't have libwmf at all.
Note: I found the packages and versions of libwmf on this website.

ImageMagick convert OOMing inside Singularity container

When I run a specific ImageMagick convert command (to produce an animated GIF) inside a Singularity container it is consistently giving an memory error:
convert-im6.q16: cache resources exhausted `foo.gif' # error/cache.c/OpenPixelCache/4083.
convert-im6.q16: memory allocation failed `foo.gif' # error/quantize.c/AssignImageColors/496.
How can I debug this?
I'm not getting any memory issues outside of Singularity which gives me the impression that either Singularity is artificially limiting my available memory or ImageMagick is configured poorly inside of Singularity. I am not seeing memory issues for any of my other applications running inside Singularity which makes me think it's an ImageMagick issue.
Here are some details about my system:
$ singularity --version
singularity version 3.7.1-1.el8
Inside the container:

Singularity> convert -list resource

Disk: 1GiB
File: 768
Thread: 256
Throttle: 0

The Memory: 256MiB stands out as especially low. I should have at least 2GiB. How does ImageMagick configure these limits and how can I change them?
The problem turned out to be with ImageMagick's system-wide policy.xml that was installed in my container. Updating that file with more generous "memory" and "disk" values fixed this problem.
You can find the location of your system's policy.xml file using the command convert -list policy (Hat tip to Kurt Pfeifle's answer which clued me in on this). For me it was at /etc/ImageMagick-6/policy.xml. You can edit that file
(if you have root access). In the end I decided just to delete the file since I don't want my system from restricting my use at all inside the container.
You can set limits via the command line, say convert -limit memory 2GiB ... or environment variables (See Kurt Pfeifle's answer for details). However, this method does not allow expanding larger than system-wide limits set in policy.xml because this policy file is meant to be a way for system administrators to forcibly limit users. Therefore, the only way to remedy this is to update/remove the system-wide policy.

How to keep Tesseract from inserting extra whitespace in words?

I asked about this on the Tesseract forum already
Via Tesseract (and ImageMagick), I'm trying to find out the text of this
PDF file
This is the section of the PDF that I'm working on, it's line #7 of the
PDF:
In this section, Tesseract is running into problems when trying to identify
the string CONSTRUCTORA.
It sees CO NSTRUCTO RA
It should see CONSTRUCTORA
Can anyone suggest any possible fixes for this?
This is the commandline sequence:
convert -density 600 my_pdf.pdf tmp.tif
tesseract -l spa tmp.tif stdout > tmp.txt
These are the software versions:
~% tesseract --version
tesseract 3.05.01
leptonica-1.74.4
libgif 4.1.6(?) : libjpeg 8d (libjpeg-turbo 1.3.0) : libpng 1.2.50 :
libtiff 4.0.3 : zlib 1.2.8
~% convert --version

For dealing with the irregular kerning of the PDF file, Will suggested tweaking the parameters around tosp_min_sane_kn_sp of the docs https://github.com/naptha/tesseract.js/blob/master/docs/tesseract_parameters.md
Setting tosp_min_sane_kn_sp=2.8 solved the issue that was described in the question.
The new Tesseract invocation is the following:
tesseract -c tosp_min_sane_kn_sp=2.8 -l spa tmp.tif stdout > tmp.txt
The default value for tosp_min_sane_kn_sp seems to be 1.5. So far, I have only tested with values larger than 1.5.

lcms error using ImageMagick compare on JPEGs with colour profile

When running compare
compare -metric MSE some-image-1.jpg some-image-2.jpg /dev/null
1) When images are identical (OK)
0 (0)
This is what I would expect to see.
2) When images differ (OK)
Error: Command failed: 13.1266 (0.000200299)
I can get the data that I want, but I'm not sure why it's presented as an error.
3) When image is a JPEG with a Photoshop colour profile (ISSUE)
Error: Command failed: lcms: Error #12288; Corrupted memory profile
This is the real issue, and only happens on JPEG images with a Photoshop colour profile - can anyone point me to why this would happen?
