Perl ImageMagick：如何禁用命令 output 的打印？

Question

I have a Perl script:

#!/usr/bin/perl

use strict;

use Image::Magick;

my $temp_filename = 'temp.webp';

my $im = Image::Magick->new;
my $m = $im->Read($temp_filename);

When I run it from the command line, I get:

$ perl test.cgi
Decoded /tmp/magick-324583Dvjs7UCnJGp. Dimensions: 450 x 300. Now saving...
Saved file /tmp/magick-324589ZiUphKo482g
$

I expect (and want):

$ perl test.cgi
$

What gives?

Answer 1

Adding

$im->SetAttribute(quiet=>1);

fixed this issue for me.

Final script:

#!/usr/bin/perl

use strict;

use Image::Magick;

my $temp_filename = 'temp.webp';

my $im = Image::Magick->new;
$im->SetAttribute(quiet=>1);
my $m = $im->Read($temp_filename);
