Introduction

RMagick is an interface between the Ruby programming language and the ImageMagick image processing library.

Prerequisites

These prerequisites are required for the latest version of RMagick.

OS

• Linux
• *BSD
• macOS
• Windows
• Other *nix-like systems

C++ compiler

• RMagick 5.4.0 or later requires a C++ compiler.

Ruby

• Version 3.0 or later.

You can get Ruby from https://www.ruby-lang.org.

Ruby must be able to build C-Extensions (e.g. MRI, Rubinius, not JRuby)

ImageMagick

• Version 6.8.9 or later (6.x.x).
• Version 7.0.8 or later (7.x.x). Require RMagick 4.1.0 or later.

You can get ImageMagick from https://imagemagick.org.

Linux

Ubuntu

On Ubuntu, you can run:

sudo apt-get install libmagickwand-dev

Centos

On Centos, you can run:

sudo yum install ImageMagick-devel

Arch Linux

On Arch Linux, you can run:

pacman -Syy imagemagick

Alpine Linux

On Alpine Linux, you can run:

apk add imagemagick imagemagick-dev imagemagick-libs

or you can run if you would like to use ImageMagick 6:

apk add imagemagick6 imagemagick6-dev imagemagick6-libs

macOS

On macOS, you can run:

brew install imagemagick

or you can run if you would like to use ImageMagick 6:

brew install imagemagick@6

Windows

1. Install latest Ruby+Devkit package which you can get from RubyInstaller for Windows.
2. You might need to configure PATH environment variable to where the compiler is located. (Ex: set PATH=C:\Ruby33-x64\bin;C:\Ruby33-x64\msys64\ucrt64\bin;%PATH%)
3. Download ImageMagick-7.XXXX-Q16-x64-dll.exe (not, ImageMagick-7.XXXX-Q16-x64-static.exe) binary from Windows Binary Release, or you can download ImageMagick 6 from Windows Binary Release.
4. Install ImageMagick. You need to turn on checkboxes Add application directory to your system path and Install development headers for C and C++ in an installer for RMagick.

Installing RMagick

Installing via Bundler

Add to your Gemfile:

gem 'rmagick'

Then run:

bundle install

Installing via RubyGems

Run:

gem install rmagick

Versioning

RMagick is versioned according to Semantic Versioning. For stable version compatible with Ruby 3.0+, use ~> 3.0. Versions >= 6 work on Ruby >= 3.x only.

Using RMagick

Require RMagick in your project as follows:

require 'rmagick'

See https://rmagick.github.io/usage.html for links to more information.

Things that can go wrong

The RMagick installation FAQ has answers to the most commonly reported problems, though may be out of date.

Can't install RMagick. Can't find libMagick or one of the dependent libraries. Check the mkmf.log file for more detailed information

Typically this message means that one or more of the libraries that ImageMagick depends on hasn't been installed. Examine the mkmf.log file in the ext/RMagick subdirectory of the installation directory for any error messages. These messages typically contain enough additional information for you to be able to diagnose the problem. Also see this FAQ.

Cannot open shared object file

If you get a message like this:

$DIR/RMagick.rb:11:in `require': libMagick.so.0:
  cannot open shared object file: No such file or directory -
  $DIR/RMagick2.so (LoadError)

you probably do not have the directory in which the ImageMagick library is installed in your load path. An easy way to fix this is to define the directory in the LD_LIBRARY_PATH environment variable. For example, suppose you installed the ImageMagick library libMagick.so in /usr/local/lib. (By default this is where it is installed.) Create the LD_LIBRARY_PATH variable like this:

export LD_LIBRARY_PATH=/usr/local/lib

On Linux, see ld(1) and ld.so(8) for more information. On other operating systems, see the documentation for the dynamic loading facility.

This operation might not be required when you can use 4.2.5 or later.

Segmentation fault

Default stack size of your operating system might be too small. Try removing the limit with this command:

ulimit -s unlimited

Upgrading

If you upgrade to a newer release of ImageMagick, make sure you're using a release of RMagick that supports that release. It's safe to install a new release of RMagick over an earlier release.

More samples

You can find more sample RMagick programs in the /examples directory. These programs are not installed in the RMagick documentation tree.

Reporting bugs

Please report bugs in RMagick, its documentation, or its installation programs via the bug tracker on the RMagick issues page.

However, We can't help with Ruby installation and configuration or ImageMagick installation and configuration. Information about reporting problems and getting help for ImageMagick is available at the ImageMagick website or the ImageMagick Forum.

Development Setup

In order to minimize issues on your local machine, we recommend that you make use of a Vagrant installation.

Steps to get up and running with a passing build are as follows:

1) set up the Vagrant environment

If you don't already have Vagrant installed, you can download and install it from here. Once installed, we can set up a pre-built environment:

git clone https://github.com/tjschuck/rake-compiler-dev-box.git
cd rake-compiler-dev-box
vagrant up

This last part will probably take a while as it has to download an Ubuntu image and configure it. If there is an error during this process, you may need to reboot your computer and enable virtualization in your BIOS settings.

2) clone RMagick and log in to the vagrant box

Within the rake-compiler-dev-box directory:

git clone https://github.com/rmagick/rmagick.git # or your fork
vagrant ssh

3) install ImageMagick and additional environment stuff

cd /vagrant/rmagick
export IMAGEMAGICK_VERSION=6.8.9-10
bash ./before_install_linux.sh

This will take just a few minutes to build ImageMagick

4) build RMagick

rake

This compiles the RMagick extensions and runs the tests. If all goes well you'll see a lot of output, eventually ending in something like:

Finished tests in 35.865734s, 11.3758 tests/s, 6560.3007 assertions/s.

408 tests, 235290 assertions, 0 failures, 0 errors, 0 skips

And you're all set! The copy of RMagick within /vagrant/rmagick inside your Vagrant session is the same as the one in the rake-compiler-dev-box directory on your machine. You can make changes locally and run tests within your ssh session.

rmagick's Issues

Removed the SplineInterpolatePixel check

Issue by joshk

Hi Guys,

In a commit in June 2009 a check in the extension config was removed relating to SplineInterpolatePixel and InterpolatePixelMethod. I noticed, after a fair bit of hunting, that the check regarding this enum was not removed in the rmmain.c file, so in the end SplineInterpolatePixel is never made available.

Here is a small patch which removes the check and makes SplineInterpolatePixel available for all :)

Thanks for the great gem!

Resolution management

Issue by daniel2d2art

Hi

I've next resource:

file: 300dpi.jpg
dimensions: 1782px x 1181px
size: 304539 bytes
resolution: 300dpi x 300dpi

when I use:

image.resize_to_fill!(460, 345)

I get:
file: 300dpi_conversion_1.jpg
dimensions: 460px × 345px
size: 21718 bytes
resolution: 300dpi x 300dpi
Result: Ok expected

Now I want to try reduce the resolution, I use:

image.density="72x72"
image.resize_to_fill!(460, 345)

I get:
file: 300dpi_conversion_2.jpg
dimensions: 460px × 345px
size: 21718 bytes
resolution: 72dpi x 72dpi
Result: resolutions seems change but size its the same at 300x300

No I try to reduze adding resample too, I use:

image.resample(72.0, 72.0)
image.density="72x72"
image.resize_to_fill!(460, 345)

I get:
file: 300dpi_conversion_3.jpg
dimensions: 460px × 345px
size: 21718 bytes
resolution: 72dpi x 72dpi
Result: resolutions seems the same 72x72 as above test, but size its the same at 300x300 too

???
How change resolutions works???, I don't get clareance about it on documentation, it's working ok?
How can I upload a image file (JPG, GIF, PNG) optional (TIFF, BMP), and transform they change resolution and resize?

Thanks

RMagick thumbnail doesn't work like ImageMagick thumbnail

Issue by mattneub
Tuesday Aug 16, 2011 at 00:47 GMT
Originally opened as #33

In ImageMagick I can say:

 $ convert marcelle.jpg -thumbnail 300x1000 -quality 90  -unsharp 0x.5 marcelle_th.jpg

The -thumbnail 300x1000 part means: resize proportionally, and be smaller than or equal to width 300 and height 1000. In other words, 300x1000 represents a maximal bounding box.

But in RMagick, pic.thumbnail(300,1000) does not resize proportionally - instead, it makes an image whose size is exactly 300x1000.

Of course I can work around this by using GreaterGeometry and change_geometry, but my point is that having to do so makes thumbnail kind of useless. So I suggest that the lack of match between ImageMagick's thumbnail behaviour and RMagick's thumbnail behavior is a possible bug.

uninitialized constant Magick::Hatchfill (NameError)

Having installed and verified ImageMagick I downloaded the latest gem for RMagick. I wanted to make sure that the RMagick installed correctly so I ran the following script:

require 'rubygems'
require 'rmagick'

canvas = Magick::Image.new(240, 300, Magick::Hatchfill.new('white', 'lightcyan2'))
gc = Magick::Draw.new

gc.fill('red')
gc.stroke('blue')
gc.stroke_width(2)
gc.path('M120, 150 h-75 a75, 75 0 1, 0 75, -75 z')
gc.fill('yellow')
gc.path('M108.5,138.5 v-75 a75,75 0 0,0 -75, 75 z')
gc.draw(canvas)

canvas.write('path.png')

No matter what I do (uninstall gem, install via tarball) I get the Hatchfill error.

RMagick 2.13.2 on Windows 7 x64

Hello. I just noticed that RMagick was updated to 2.13.2 and that it should support ImageMagick 6.8. So i uninstalled my old ImageMagick, downloaded a new one (6.8.2-3-Q16-x64-dll) and installed in with C/C++ headers. Then i tried to install RMagick using instructions found in the Wiki (it helped me to install rmagick 2.13.1), but got the following error:

======================================================================
Mon 04Feb13 15:18:18

Exactly the same error i got when trying to use ImageMagick x86. My Ruby version is 1.9.3-p374. I recall, that when trying to use ImageMagick 6.8 with older rmagick 2.13.1 i got the same (or near the same) error about conflicting types.

Any clues about this issue?

Hi!

I'm trying to use rmagick as gem along Rails 3.0.0, but one problem has been a big stone in my way!!

So, when my Rails APP calls one module called FactoryImg, where I've used RMagick for 'read' a image from filesystem one error is showed in the console and my contener web is turned down!

You can see the log here http://pastie.org/1256503

Can help me??

While reading image file,colorspace will not be set in block

this doesn't work,

 self.colorspace = Magick::LABColorspace

p image.colorspace == Magick::LABColorspace

this works

image = Magick::Image.new(100,100)
image.colorspace = Magick::LABColorspace
p image.colorspace == Magick::LABColorspace

Why can't the colorspace be set during the block? Is this a bug or intended (if so, why?).

ImageMagic installed via Homebrew doesn't work

Issue by jkamenik
Thursday Dec 01, 2011 at 18:55 GMT
Originally opened as #39

I use a Mac, and homebrew for many packages including ImageMagick. I noticed a very annoying issue that I had to work around. Homebrew symlinks to /usr/local/bin and /usr/local/include. For example: /usr/local/include/ImageMagick -> /usr/local/homebrew/.../ImageMagick. This works fine with most libraries that need imagemagick since Magick-config produces the correct paths to the symlinks and the compilers just follow the sym links.

The rmagic gem compile does not seem capible of following symlinks and therefore cannot find /usr/local/include/wand/MagickWand.h which is there.

$ gem install rmagick

My solution was to install ImageMagick via https://github.com/maddox/magick-installer/blob/master/magick-installer.sh, which doesn't use symlinks. Without symlinks things work fine.

Hi!

Using rmagick (2.13.2) with ImageMagick 6.8.6 on OS X 10.8.4. Given the following example:

script.each_line { |line| d.primitive line }

vector density on read

Issue by hynkle
Saturday Jun 04, 2011 at 19:16 GMT
Originally opened as #25

---

I'm trying to convert a vector image to a raster image of a larger size, let's say 4x larger. Suppose just running convert img.svg img.png gives you a 100x100 image.

With ImageMagick's convert command, the conversion with enlargement would look like:

convert -density 288 img.svg img.png

Where 288 is of course 4x the default density of 72. And that works beautifully, resulting in the desired 400x400 image without the ugly artifacts you'd get from upsampling a 100x100 raster image to 400x400 (which is indeed why I'm using a vector image for the original in the first place).

But what I would have thought was the corresponding RMagick code:

image = Magick::Image.read('img.svg'){self.density = 144}.first
image.write('img.png')

... results in the same 100x100 image you'd get by just running convert img.svg img.png. Moreover, the image reports its density as "72x72" as though I hadn't supplied anything in read's block.

Am I simply approaching this problem wrong, or this a bug?

ImageList destroy!

It looks like if you call destroy! on an ImageList instance it destroys only the last image in the list. If this is the case other people might make the same mistake I did and not be destroying what they thought they were.

Should ImageList.destroy do

il.each { |i| i.destroy! }

Converting JPEG from RGB to CMYK results in segfault

Issue by meanphil
Tuesday Jul 10, 2012 at 23:27 GMT
Originally opened as #55

Trying to save any image as a CMYK Jpeg will result in a crash. If you change CMYK to any other colorspace such as RGB, CMY, or Gray it writes the image OK.

My test script is as follows:

require 'rubygems'; require 'RMagick'

i = Magick::Image.read('test.jpg').first 
i.write("cmyk.jpg") do |ii|
    ii.format = 'JPEG'
    ii.colorspace = Magick::CMYKColorspace
end

$ ruby test.rb 
test.rb:4: [BUG] Segmentation fault

gdb says the segfault is in ImageMagick here:

However the following command line works fine, so it must be something that RMagick is (not?) doing:

convert test.jpg -colorspace CMYK cmyk.jpg

Environment is Ruby 1.9.3-p194, ImageMagick 6.7.7-7, RMagick 2.13.1, FreeBSD 8.2, gcc 4.2.1

don't conflate SetImageColorspace and TransformImageColorspace

Issue by smparkes
Sunday Apr 21, 2013 at 23:04 GMT
Originally opened as #75

rmagick is conflating SetImageColorspace and TransformImageColorspace. This is the difference between "convert foo.png -set colorspace rgb ..." and "convert foo.png -colorspace rgb ..."

The former is like a reinterpret-cast in C++: it doesn't change the data, it just says the data is the given colorspace. The latter is a transform that changes the data based on the original image colorspace and the parameter.

I need SetImageColorspace and in the current code, it's not available if TransformImageColorspace is available.

This is a partial patch. I didn't wire in or test image.transform_colorspace(colorspace). If you're interested, I can ...

Annotating fails when '@' is first character

Issue by VxJasonxV
Thursday Nov 08, 2012 at 10:44 GMT
Originally opened as #59

---

I had a script in use for years that would record data from Last.fm, and build an image out of various song information.

Some time ago, on the order of months, this script would keep showing the current song being played, but would simply stop working when showing historical playback data.

After poking around, it appears that this was due to a leading @ character when using the annotate method. The rest of the data following the at-symbol does not appear to have any affect.

When invoked, Ruby would return this information:

bin/lastfmsig.rb:14:in `annotate': no text (ArgumentError)
        from bin/lastfmsig.rb:14:in `text'
        from bin/lastfmsig.rb:42
        from bin/lastfmsig.rb:37:in `each'
        from bin/lastfmsig.rb:37

shell returned 1

Changing the first three characters to be " @ " (space-at-space, really any character leading besides @) appears to have fixed this issue.

RMagick ignoring border_color

collage = imagelist.montage do

  self.border_width=10
  self.geometry=Geometry.new(500, 500)
end

collage.write('/home/jan/Desktop/test_collage.jpg')

IMGCOMMAND="-border 10x10 -bordercolor red -geometry 500x500 /home/jan/Desktop/test_collage_original.jpg"
system "montage /home/jan/Desktop/test.jpg " + IMGCOMMAND

A red border is created with the original imagemagick (test_collage_original) while it is white with Rmagick (test_collage). It should be red in both cases...

"stack level too deep" when calling Magick::Image.read within a fiber (Ruby 1.9.3-p0)

Hi!

I'm not exactly sure what's going on since I get inconsistent results between my Linux dev box and my OS X dev box, both running the same version of Ruby (1.9.3-p0), both using rvm, both running the same version of RMagick (2.13.1), and both running the same version of ImageMagick (6.7.1, compiled from source).

My OS X dev box plays along nicely, but my Linux dev box throws a "stack level too deep" exception when I call Magick::Image.read within a fiber. I'm using the fiber to untangle evented code in a fashion quite similar to igrigorik's em-synchrony project), so this is all being done within the context of EventMachine's event loop. If I downgrade to Ruby 1.9.2-p290 on my Linux box, RMagick begins to work fine again.

Really at quite a loss why OS X would behave but Linux wouldn't. I don't know what else I ought to provide to help track down the issue, but I'd be happy to post anything extra anyone requests.

Thanks!

Really, would it be so much trouble for you to please build and post a binary for a current ruby 1.9.1/win32 runtime? Tonight?! Otherwise this is blocking ruby development with 'rmagick' dependencies for a lot of people. I really have other things to do than build rmagick from source right now as I see it doesn't build with mingw! Thanks!

Rails 3 Development mode crashes after the first usage of ImageMagick

Issue by jeffdeville

The error message is:
cannot remove Object::Version

I think what's happening is that in development mode, Rails tries to clear itself, and reload the environment somewhat after each page. It's this process that is dying. (The code that actually manipulates my image works, and setting cache_classes: true avoids the problem, but makes it necessary to restart my development server constantly.

Whether from rails, script, or irb, anytime I attempt to even open an image the process locks up. It does not even respond to ctrl-c. I have to force quit it. I compiled ImageMagick with --disable-openmp and convert works as expected from the command line. Is this a known issue?

Problems installing with homebrew (and not macports)

Issue by tute

I hardwired the following to be able to install rmagick, since I don't have Macports:

$ sudo ln -s /bin/mkdir /opt/local/bin/gmkdir $ sudo ln -s /usr/bin/install /opt/local/bin/ginstall

Because I've seen in lines 85 and 86 of ext/RMagick/Makefile:

MAKEDIRS = /opt/local/bin/gmkdir -p INSTALL = /opt/local/bin/ginstall -c

Shouldn't the Makefile test if /opt/local/bin/gmkdir and /opt/local/bin/ginstall exists?

Regards,

Tute.

Image#remap produces an unreasonable result for the attached images. The pixel at 0,0 is remapped from (254, 254, 254) -> (255, 227, 0) despite there being a (255, 255, 255) in the remap_image ("colors" below), which is much closer in RGB space than the color picked.

I am trying to install rmagick on a shared host. I don't have root access.

I compiled ImageMagick like this:

./configure --prefix=$HOME/bin --disable-static --with-modules --without-perl --without-magick-plus-plus --with-quantum-depth=8 --with-gs-font-dir=$FONTS

Then I exported the paths and tried to install the gem:

export CPPFLAGS="-I/home/dorfbran/bin/include/ImageMagick" 
gem install rmagick

Ruby 2.0 warnings

Issue by dicom

Originally opened as #69

Hello

I just tried installing the RMagick gem on the newly released Ruby 2.0.0 on Windows XP 32-bit (using DevKit), and it seems to produce several warnings while building the documentation. These are probably related to the fact that Ruby 2.0 has switched default encoding from ASCII-8BIT to UTF-8. Although RMagick seems to work fine after the install, I still think these warnings should be eliminated, to avoid alarming the user.

Here's the installation log:
