in thread Interpolating data using pdl
Hello Again,
Based on What i'm trying to do is something like resizing a image. Suppose i have a 100x100 image and i want to resize it to 1000x1000. you could use Image::Resize. Sample of code from documentation:
use Image::Resize; $image = Image::Resize->new('large.jpg'); $gd = $image->resize(250, 250);
But also Image::Imlib2. Sample of code from Stretch, resize, or thumbnail an image using Perl:
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");
