使用Perl拉伸,调整大小或缩放图像

如何使用Perl脚本拉伸或调整图像(任何格式)？

我推荐Image :: Imlib2 ...如果你可以在你的机器上安装imlib2

请参阅文档:Image :: Imlib2

use Image::Imlib2;

# load image from file
my $image = Image::Imlib2->load("in.png");

# get some info if you want
my $width  = $image->width;
my $height = $image->height;

# scale the image down to $x and $y
# you can set $x or $y to zero and it will maintain aspect ratio
my $image2 = $image->create_scaled_image($x,$y);

# save thumbnail to file
$image2->save("out.png");
