Configure jmagick 6.4.0 in centos 6.2

After various Collection on the Internet, we finally got it done. Record that sudo needs to be used for root permission in some places:

(1) ensure that the system has installed the following packages:

Rpm-Q libjpeg-devel libpng-devel LibTIFF-devel libungif-devel Perl-CPAN Perl make gcc

Or directly use the following command to install
Yum install libjpeg
Yum install libjpeg-devel
Yum install libpng
Yum install libpng-devel
Yum install LibTIFF
Yum install LibTIFF-devel
Yum install libungif
Yum install libungif-devel
Yum install Perl-CPAN

(For example, if Perl-CPAN is not installed, the following error will be reported: can't locate extutils/makemaker. pm)

(2) install ImageMagick. It is best to ensure that the ImageMagick and jmagic versions are consistent.

1. Download imagemagick-6.4.0-0.tar.gz from
Wget http://downloads.jmagick.org/6.4.0/ImageMagick-6.4.0-0.tar.gz,
2. Tar-xzvf ImageMagick-6.4.0-0.tar.gz
3. mkdir/usr/local/ImageMagick
4. CD ImageMagick-6.4.0-0
5 ../configure -- prefix =/usr/local/ImageMagick/
6. First make, then make install, then VI/etc/profile, add: export $ Path = $ path:/usr/local/ImageMagick/bin at the end.

Check whether the installation is successful by using the following method: Check: Convert 1.jpg-resize 50% 11.jpg

(3) install jmagick. It is best to ensure that the ImageMagick and jmagic versions are consistent.

1. Download jmagick from http://downloads.jmagick.org/6.4.0/jmagick-6.4.0-src.tar.gz
2. Tar-xzvf jmagick-6.4.0-src.tar.gz
3. CD jmagick-6.4.0-src
4../configure
5. Make, make install
6. CD lib
# The so file must be stored in/usr/lib/; otherwise, the. So library file cannot be found in Java.
7. Cp *. So/usr/lib)
# Load the so library file path to the configuration file
8. VI/etc/lD. So. conf, add:/usr/local/ImageMagick/lib
9. ldconfig # load to the Library File Cache

(4) test code:

Import java. AWT. dimension;
Import java. Text. simpledateformat;
Import java. util. calendar;

Import magick. imageinfo;
Import magick. magickimage;
