如何使用Perl脚本拉伸或调整图像(任何格式)？
解决方法
我推荐
Image :: Imlib2 …如果你可以在你的机器上安装imlib2
参见文档：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");
