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);
