my ($width, $height ) = ...;
my ($max_width, $max_height ) = (800, 600);
my ($width_factor, $height_factor) = ($max_width/$width, $max_height/$
+height);
if ($width_factor < 1 || $height_factor < 1) {
my $factor = ($width_factor < $height_factor
? $width_factor
: $height_factor
);
$width = int($width * $factor + 0.5);
$height = int($height * $factor + 0.5);
}
The above was extracted from a script I use to resize images.
use Image::Magick qw();
my $img = Image::Magick->new();
my $file_name = ...;
my $img->Read($file_name);
my ($width, $height ) = $img->Get(qw( width height ));
my ($max_width, $max_height ) = (800, 600);
my ($width_factor, $height_factor) = ($max_width/$width, $max_height/$
+height);
if ($width_factor < 1 || $height_factor < 1) {
my $factor = ($width_factor < $height_factor
? $width_factor
: $height_factor
);
my $new_width = int($width * $factor + 0.5);
my $new_height = int($height * $factor + 0.5);
$img->Resize(width => $new_width, height => $new_height);
$img->Write($file_name);
}
