I tried to replace Image:Info which fails on some input images with
Image::Size in my program, however I've noticed that it decreased the
speed of my script several times, from few seconds to few minutes on
same set of images (the input set of images was mix of various images,
mostly JPEG's with few PNG's and GIF's in small sizes (few hundred
generated thumbnails 150x150 px)).
Basically, I just replaced:
use Image::Info qw(image_info dim);
...
$info=image_info($imagename);
($w,$h) = dim($info);
...
with:
use Image::Size;
...
($w,$h)=imgsize($imagename);
...
and the script was then much slower
I think the speed need to be improved.
I am using Image::Size from debian package libimage-size-perl, version 3.220-1
