perl - Error Image::Compare (jpg files) -



perl - Error Image::Compare (jpg files) -

i'm trying utilize image::compare in perl compare 2 images based on colors used in images. here code i'm using:

#!/usr/bin/perl utilize strict; utilize warnings; utilize image::compare; ($cmp) = image::compare->new(); $cmp->set_image1( img => "$argv[0]", type => 'jpg', ); $cmp->set_image2( img => "$argv[1]", type => 'jpg', ); $cmp->set_method( method => &image::compare::threshold, args => 70, ); if ( $cmp->compare() ) { print "same \n"; } else { print "not same\n"; }

when run it, gave error:

unable read image info file 'test_002.jpg': 'format 'jpg' not supported - formats bmp, ico, pnm, raw, sgi, tga available reading - can't locate imager/file/jpg.pm or imager/file/jpgreader.pm' @ /usr/local/share/perl/5.18.2/image/compare.pm line 162.

i've tried install imager::file::jpeg, gave me errors:

$ cpan install imager::file::jpeg reading '/home/b0y/.cpan/metadata' database generated on sat, 18 oct 2014 07:05:12 gmt running install module 'imager::file::jpeg' running create t/to/tonyc/imager-file-jpeg-0.88.tar.gz checksum /home/b0y/.cpan/sources/authors/id/t/to/tonyc/imager-file-jpeg-0.88.tar.gz ok

many thanks.

you need install "libjpeg-dev",

sudo apt-get install libjpeg-dev
