Class Phalcon\Image\Adapter\GD

extends abstract class Phalcon\Image\Adapter

implements Phalcon\Image\AdapterInterface

Image manipulation support. Allows images to be resized, cropped, etc.

$image = new Phalcon\Image\Adapter\GD("upload/test.jpg");
$image->resize(200, 200)->rotate(90)->crop(100, 100);
if ($image->save()) {
    echo 'success';
}

public Phalcon\Image\Adapter resize ([unknown $width], [unknown $height], [unknown $master]) inherited from Phalcon\Image\Adapter

Resize the image to the given size. Either the width or the height can be omitted and the image will be resized proportionally.

public Phalcon\Image\Adapter liquidRescale (unknown $width, unknown $height, [unknown $delta_x], [unknown $rigidity]) inherited from Phalcon\Image\Adapter

This method scales the images using liquid rescaling method. Only support Imagick

public Phalcon\Image\Adapter crop (unknown $width, unknown $height, [unknown $offset_x], [unknown $offset_y]) inherited from Phalcon\Image\Adapter
