Hello @all!

How can I optimize this?

The script should read .tiff's, write a text at the top and write again to STDOUT.

until ImageToBlob () takes 0.10 ms,with ImageToBlob it takes up to 3 sec.

Thanks in advance!

#!/usr/bin/perl
use strict;
use warnings;
use Image::Magick;
use Data::Dumper;
use POSIX;

my $def = shift || '/var/www/html/error.tif';
my $uri = $ENV{'PATH_TRANSLATED'} || $def;
my $debug = 1;

my $img = Image::Magick->new();
$img->Read( "tif:" . ( -e $uri ? $uri : $def ) );

my ( $dev, $ino, $mode, $nlink, $uid, $gid, $rdev, $size, $atime, $mti
+me, $ctime, $blksize, $blocks ) = stat($uri);
my $scan_date;

my $date_create = POSIX::strftime( '%d-%m-%Y %H:%M:%S', localtime $cti
+me );

if ( $date_create =~ m/(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2})
+.*/ ) {
    $date_create = $3 . "." . $2 . "." . $1 . " " . $4 . ":" . $5 . ":
+" . $6;
}
$scan_date = $date_create;
$img->Annotate(
    y          => 10,
    text       => "Scanned: " . $scan_date,
    font       => "ArialBkI",
    pointsize  => 36,
    fill       => 'white',
    gravity    => 'north',
    undercolor => 'black',
);

my $out = $img->ImageToBlob();
print "Content-type: image/tiff\n\n" . $out if ( $debug < 1 );
