Building GraphicsMagick

GraphicsMagick is a powerful tool for processing image files. I'm using MinGW to build GraphicsMagick for Windows.

1. zlib 1.2.7

   
   

   Download the zlib source (zlib-1.2.7.tar.gz) and unpack it.

   
   

   tar xzvf zlib-1.2.7.tar.gz
   cd zlib-1.2.7

   
   

   Compile and install zlib.

   
   

   make -f win32/Makefile.gcc
   cp -iv zlib1.dll /mingw/bin
   cp -iv zconf.h zlib.h /mingw/include
   cp -iv libz.a /mingw/lib
   cp -iv libz.dll.a /mingw/lib

   
   
   

2. bzip2

   
   

   Now download bzip2 source from bzip.org and unpack it.

   
   

   tar xzvf bzip2-1.0.6.tar.gz
   cd bzip2-1.0.6

   
   

   Change line 78 of bzlib.h to read:

   
   

   #if defined(_WIN32) && !defined(__MINGW32__)

   
   

   Compile and install bzip2.

   
   

   make
   cp bzlib.h /mingw/include/
   cp libbz2.a /mingw/lib

   
   
   

3. liblzma

   
   

   Get the XZ Utils source code and unpack it. Go to the src/liblzma folder and compile liblzma like this:

   
   

   tar xzvf xz-5.0.4.tar.gz
   cd xz-5.0.4
   ./configure --prefix=/mingw
   cd src/liblzma
   make
   make install

   
   
   

4. libpng 1.5.12 and libjpeg 8d

   
   

   Compile libpng and libjpeg as follows:

   
   

   ./configure --prefix=/mingw
   make
   make install

   
   
   

5. libjasper

   
   

   Compile Jasper:

   
   

   ./configure --prefix=/mingw
   make
   make install

   
   

   If you encounter an error "undefined reference to _sleep", replace sleep() with _sleep with a factor of 1000 in the code:

   
   

   _sleep(1000)

   
   
   

6. JBig

   
   

   Get jbigkit from here.

   
   

   make
   cp libjbig/*.h /mingw/include
   cp libjbig/*.a /mingw/lib

   
   
   

7. libtiff 4.0.2

   
   

   Compile libtiff like this:

   
   

   ./configure --prefix=/mingw
   make
   make install

   
   

   If the shared library libtiff-5.dll is not generated and you want to create it manually, use such a command as the following and update libtiff.la accordingly:

   
   

   gcc -shared -o libtiff-5.dll -Wl,--out-implib,libtiff.dll.a -Wl,--whole-archive /mingw/lib/libtiff.a -Wl,--no-whole-archive -L/mingw/lib -ljpeg -ljbig -llzma -lz

   
   
   

8. freetype

   
   

   Compile freetype:

   
   

   ./configure --prefix=/mingw
   make
   make install

   
   
   

9. libxml2

   
   

   Compile libxml2:

   
   

   ./configure --prefix=/mingw
   make
   make install

   
   
   

10. libwmf 0.2.8.4

    
    

    Compile libwmf:

    
    

    ./configure --prefix=/mingw
    make
    make install

    
    
    

11. Little CMS

    
    

    Compile liblcms:

    
    

    ./configure --prefix=/mingw
    make
    make install

    
    
    

12. Build GraphicsMagick

    
    

    Get GraphicsMagick code and build it like this:

    
    

    ./configure --prefix=/mingw --with-gs-font-dir='C:/Windows/Fonts' --with-windows-font-dir='C:/Windows/Fonts' LIBS='-ljbig'
    make 
    make install

    
    

Creating a PDF document from JPEG files

GraphicsMagick comes in handy when you want to convert scanned JPEG images to a PDF document:
