NAME

Image::Resize::OpenCV - Simple image resizer using OpenCV

SYNOPSIS

            

              
              
use Image::Resize::OpenCV;
$image = Image::Resize::OpenCV -> new('large.jpg');
print ("WIDTH:" . $image -> width . " HEIGHT:" . $image -> height);
$image -> resize(250, 250);
$image -> save("small.jpg");
# OR
use Image::Resize::OpenCV qw(image_resize);
image_resize('large.jpg', 250, 250);
            
          

DESCRIPTION

            

              
              
Image::Resize::OpenCV using openCV library for resize images. openCV more faster then GD, ImageMagick, GraphicsMagick etc.
OpenCV more quality then GD and have 4 interpolation mode for resize images.
            
          

EXPORT

            

              
              
image_resize($filename, $width, $height, $out_filename = undef);
            
          

METHODS

new($filename = undef) - Constructor

            

              
              
Create a new mage::Resize::OpenCV object 
my $image = new Image::Resize::OpenCV();
my $image = new Image::Resize::OpenCV($filename);
            
          

load($filename) - Load image file

            

              
              
$image -> load($filename);
            
          

resize($width, $height, ...) - Resize Image

            

              
              
$image -> resize(640, 480);
$image -> resize(640, 480, KEEP_ASPECT => 1);
$image -> resize(640, 480, INTER => 1);
$image -> resize(640, 480, KEEP_ASPECT => 1, INTER => 1);
# INTER - Interpolation:
# 0 - nearest-neigbor
# 1 - bilinear
# 2 - pixel area relation
# 3 - bicubic
            
          

save($filename, $compress = 25) - Save image

            

              
              
$image -> save('/tmp/11.jpg');
$image -> save('/tmp/11.jpg', 50);
            
          

width()

height()
