Export multi page pdf with gimp

by

I understand that it may be possible using imageMagicks:

convert image.mng out.pdf

however is there a gimp way of doing this?

I also saw this script/plugin which uses convert:

# GIMP plugin to export layers as a multiple pages PDF file
#
#
# Note for Windows users:
#
# You need add the ImageMagic directory (which consists the 'convert.exe' executable file)
# to the GIMP environment PATH variable into the file:
# C:\Program Files\GIMP 2\lib\gimp\2.0\environ\default.env
#
# like in the example here:
# PATH=${gimp_installation_dir}\bin;${gimp_installation_dir}\32\bin;C:\Program Files\ImageMagick-6.9.1-Q16
# PYTHONPATH=${gimp_installation_dir}\32\lib\gimp\2.0\python

However, I am not seeing a /Applications/GIMP.app/Contents/Resources/share/gimp/2.0/plug-ins folder, so i made one and put the python script inside of it as well as ran chmod +x on the script.

I also saw something in the python-fu browser, but have no idea how to use it:

enter image description here

“images” is undefined:

enter image description here

Gimp 2.8.14 Mac osx

I also followed some advice to look in /Library but didn’t find anything:

➜  /Library  sudo find . | grep -i gimp
Password:
./Caches/Homebrew/brew-cask--git/Casks/gimp.rb
./Caches/Homebrew/brew-cask--git/Casks/lisanet-gimp.rb
./Caches/Homebrew/Formula/gimp.brewing

Is there anyway to easily install plugins that I am missing here?

update

With the help of @tmanni in irc i was able to find the script path /Applications/GIMP.app/Contents/Resources/lib/gimp/2.0/plug-ins inside preferences > plug-ins:

enter image description here

However, the plugin would exit saying convert is not installed.

I then tried to add /usr/local/bin to the Plug-Ins path in the menu but it then crashes with an exit code status of -5.

I then tried to directly ln -s /usr/local/bin/convert /Applications/GIMP.app/Contents/Resources/bin/convert but no dice there either.

After spending the better part of a week fiddling around with this:

Solution:

I opened a git repo for this script, I was a bit surprised about how difficult the plugin registry for gimp was, however I got it to a point where it will work if the pdf is exported with a quality less than 100:

The longer story:

Basically what was happening was gimp was using the default libraries that are included with gimp (sounds like a good idea) until I open gimp from terminal:

➜  ~  /Applications/GIMP.app/Contents/MacOS/GIMP ~/Desktop/Export_These_Layers.xcf
...
dyld: Library not loaded: /usr/local/lib/libfreetype.6.dylib
  Referenced from: /usr/local/bin/convert
  Reason: Incompatible library version: convert requires version 19.0.0 or later, but libfreetype.6.dylib provides version 18.0.0

convert is installed?:

➜  ~  ls -la /usr/local/bin/convert
    lrwxr-xr-x  1 jmunsch  admin  41 Nov 26 15:47 /usr/local/bin/convert -> ../Cellar/imagemagick/6.9.2-6/bin/convert

what libraries is convert using

➜  ~  otool -L /usr/local/bin/convert
    /usr/local/bin/convert:
        /usr/local/Cellar/imagemagick/6.9.2-6/lib/libMagickCore-6.Q16.2.dylib (compatibility version 3.0.0, current version 3.0.0)
        /usr/local/Cellar/imagemagick/6.9.2-6/lib/libMagickWand-6.Q16.2.dylib (compatibility version 3.0.0, current version 3.0.0)
        /usr/local/opt/freetype/lib/libfreetype.6.dylib (compatibility version 19.0.0, current version 19.0.0)
        /usr/local/opt/xz/lib/liblzma.5.dylib (compatibility version 8.0.0, current version 8.2.0)
        /usr/lib/libbz2.1.0.dylib (compatibility version 1.0.0, current version 1.0.5)
        /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)
        /usr/local/opt/libtool/lib/libltdl.7.dylib (compatibility version 11.0.0, current version 11.1.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

Everything appears to be up to date?

So how many places is that library?:

➜  ~ locate libfreetype
    /Applications/GIMP.app/Contents/Resources/lib/libfreetype.6.dylib
    /Applications/Steam.app/Contents/MacOS/libfreetype.dylib
    /Volumes/Gimp 2.8.14/GIMP.app/Contents/Resources/lib/libfreetype.6.dylib
    /usr/X11/lib/libfreetype.6.dylib
    /usr/local/Cellar/freetype/2.6_1/lib/libfreetype.6.dylib
    /usr/local/Cellar/freetype/2.6_1/lib/libfreetype.a
    /usr/local/Cellar/freetype/2.6_1/lib/libfreetype.dylib
    /usr/local/lib/libfreetype.6.dylib
    /usr/local/lib/libfreetype.a
    /usr/local/lib/libfreetype.dylib

Oh, I see:

➜ ~ otool -L /Applications/GIMP.app/Contents/Resources/lib/libfreetype.6.dylib
    /Applications/GIMP.app/Contents/Resources/lib/libfreetype.6.dylib:
        /usr/local/lib/libfreetype.6.dylib (compatibility version 19.0.0, current version 18.0.0)

So I copy it over:

➜  ~  cp /usr/local/opt/freetype/lib/libfreetype.6.dylib /Applications/GIMP.app/Contents/Resources/lib

And Retry:

➜  ~  /Applications/GIMP.app/Contents/MacOS/GIMP ~/Desktop/Export_These_Layers.xcf
Setting up environment...
Enabling internal Python...
Launching GIMP...
dyld: Library not loaded: /usr/local/lib/libpng16.16.dylib
  Referenced from: /Applications/GIMP.app/Contents/Resources/lib/libfreetype.6.dylib
  Reason: Incompatible library version: libfreetype.6.dylib requires version 34.0.0 or later, but libpng16.16.dylib provides version 29.0.0
[1]    69814 trace trap  /Applications/GIMP.app/Contents/MacOS/GIMP ~/Desktop/Export_These_Layers.xcf

so I try libpng and copy it over to gimp:

➜  ~  locate libpng16 
.
.
.
➜  ~  cp /usr/local/Cellar/libpng/1.6.18/lib/libpng16.16.dylib /Applications/GIMP.app/Contents/Resources/lib

Restart the gimp from terminal and retry using the plugin:

dyld: Library not loaded: /usr/local/opt/xz/lib/liblzma.5.dylib
  Referenced from: /usr/local/bin/convert
  Reason: Incompatible library version: convert requires version 8.0.0 or later, but liblzma.5.dylib provides version 6.0.0

okay where is it pulling this library from:

➜  ~  otool -L /usr/local/lib/liblzma.5.dylib
/usr/local/lib/liblzma.5.dylib:
    /usr/local/opt/xz/lib/liblzma.5.dylib (compatibility version 8.0.0, current version 8.2.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

➜  ~  otool -L /Applications/GIMP.app/Contents/Resources/lib/liblzma.5.dylib
liblzma.5.dylib:
    /Users/gimpdev/gimp/10.6/inst/lib/liblzma.5.dylib (compatibility version 6.0.0, current version 6.4.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.0)

And so I copy that file over as well:

cp /usr/local/lib/liblzma.5.dylib /Applications/GIMP.app/Contents/Resources/lib

Yet another issue after linking the new libraries:

convert: unable to load module `/usr/local/Cellar/imagemagick/6.9.2-6/lib/ImageMagick//modules-Q16/coders/png.la': file not found @ error/module.c/OpenModule/1300.

I retry but build from source this time:

brew install imagemagick --build-from-source

Retry and same issue with PNG module, So I run brew doctor:

echo 'export PATH="/usr/local/sbin:$PATH"' >> ~/.zshrc

So I retry installing libpng:

➜  ~   brew uninstall imagemagick; brew install imagemagick;brew install libpng; brew link libpng
    Warning: libpng-1.6.19 already installed
    Warning: Already linked: /usr/local/Cellar/libpng/1.6.19
    To relink: brew unlink libpng && brew link libpng

➜  ~   brew unlink libpng && brew link libpng
    Unlinking /usr/local/Cellar/libpng/1.6.19... 18 symlinks removed
    Linking /usr/local/Cellar/libpng/1.6.19... 18 symlinks created

And xz:

brew uninstall xz
brew uninstall imagemagick; brew install imagemagick --build-from-source

And finally go for some harder rebuilding:

brew uninstall --force imagemagick; brew install -v imagemagick --build-from-source

I looked at the docs for convert’s ReadImage:

open /usr/local/Cellar/imagemagick//6.9.1-10/share/doc/ImageMagick-6/www/api/constitute.html

I read the source code for ReadImage.

I stop, and look back at the python script.
I force the script to use jpeg instead of png.

It works.
