| Introduction |
| |
| PerlMagick, is an objected-oriented Perl interface to ImageMagick. |
| Use the module to read, manipulate, or write an image or image sequence |
| from within a Perl script. This makes it suitable for Web CGI scripts. You |
| must have ImageMagick 7.0.0 or above installed on your system for this |
| module to work properly. |
| |
| See |
| |
| http://www.imagemagick.org/script/perl-magick.php |
| |
| for additional information about PerlMagick. If you have problems, go to |
| |
| http://www.imagemagick.org/discourse-server/viewforum.php?f=7 |
| |
| for help. For instructions about installing ImageMagick, see |
| |
| http://www.imagemagick.org/ |
| |
| |
| Installation |
| |
| Get the PerlMagick distribution and type the following: |
| |
| gunzip ImageMagick-7.0.0-0.tar.gz |
| tar xvf ImageMagick-7.0.0 |
| |
| Follow the ImageMagick installation instructions in INSTALL-unix.txt |
| then type |
| |
| cd PerlMagick |
| |
| Next, edit Makefile.PL and change LIBS and INC to include the appropriate |
| path information to the required libMagick library. You will also need |
| library search paths (-L) to JPEG, PNG, TIFF, etc. libraries if they were |
| included with your installed version of ImageMagick. If an extension |
| library is built as a shared library but not installed in the system's |
| default library search path, you may need to add run-path information |
| (often -R or -rpath) corresponding to the equivalent library search |
| path option so that the library can be located at run-time. |
| |
| To create and install the dymamically-loaded version of PerlMagick |
| (the preferred way), execute |
| |
| perl Makefile.PL |
| make |
| make install |
| |
| To create and install a new 'perl' executable (replacing your existing |
| PERL interpreter!) with PerlMagick statically linked (but other libraries |
| linked statically or dynamically according to system linker default), |
| execute |
| |
| perl Makefile.PL |
| make perl |
| make -f Makefile.aperl inst_perl |
| |
| or to create and install a new PERL interpreter with a different name |
| than 'perl' (e.g. 'PerlMagick') and with PerlMagick statically linked |
| |
| perl Makefile.PL MAP_TARGET=PerlMagick |
| make PerlMagick |
| make -f Makefile.aperl inst_perl |
| |
| See the ExtUtils::MakeMaker(3) manual page for more information on |
| building PERL extensions (like PerlMagick). |
| |
| For Windows systems, type |
| |
| perl Makefile.nt |
| nmake install |
| |
| For Unix, you typically need to be root to install the software. |
| There are ways around this. Consult the Perl manual pages for more |
| information. You are now ready to utilize the PerlMagick routines from |
| within your Perl scripts. |
| |
| Installation - Win32 Strawberry perl |
| |
| On Win32 Strawberry perl the prefered way of installing PerlMagick is the |
| following: |
| |
| 1) Download and install ImageMagick Windows binaries from |
| http://www.imagemagick.org/script/binary-releases.php#windows |
| |
| 2) You HAVE TO choose dynamic (DLL) ImageMagick binaries. Note: it is not |
| possible to mix 32/64bit binaries of perl and ImageMagick |
| |
| 3) During installation select that you want to install ImageMagick's |
| development files (libraries+headers) |
| |
| 4) You NEED TO have ImageMagick's directory in your PATH. Note: we are |
| checking the presence of convert.exe or identify.exe tools |
| |
| 5) You might need Visual C++ Redistributable Package installed on your |
| system. See instructions on ImageMagick's Binary Release webpage. |
| |
| 6) If you have all prerequisites 1)...5) you can simply install |
| ImageMagick by running: cpan -i Image::Magick |
| |
| |
| Testing PerlMagick |
| |
| Before PerlMagick is installed, you may want to execute |
| |
| make test |
| |
| to verify that PERL can load the PerlMagick extension ok. Chances are |
| some of the tests will fail if you do not have the proper delegates |
| installed for formats like JPEG, TIFF, etc. |
| |
| To see a number of PerlMagick demonstration scripts, type |
| |
| cd demo |
| make |
| |
| |
| Example Perl Magick Script |
| |
| Here is an example script to get you started: |
| |
| #!/usr/bin/perl |
| use Image::Magick; |
| |
| $q = Image::Magick->new; |
| $x = $q->Read("model.gif", "logo.gif", "rose.gif"); |
| warn "$x" if $x; |
| |
| $x = $q->Crop(geom=>'100x100+100+100'); |
| warn "$x" if $x; |
| |
| $x = $q->Write("x.gif"); |
| warn "$x" if $x; |
| |
| The script reads three images, crops them, and writes a single image |
| as a GIF animation sequence. |
