Resizing images

##Width and height

The width and height of the Image can be modified by calling the width and height functions and passing in the desired dimensions in pixels. The resized image will be contained within the given $width and $height dimensions respecting the original aspect ratio.

$image->width(int $width);
$image->height(int $height);

##Example usage

Image::load('example.jpg')
    ->width(250)
    ->height(250)
    ->save();

##Fit

The fit method fits the image within the given $width and $height dimensions (pixels) using a certain $cropMethod.

$image->fit(string $cropMethod, int $width, int $height);

The following $cropMethods are available through constants of the Manipulations class:

##Manipulations::FIT_CONTAIN

This is the default fitting method. The image will be resized to be contained within the given dimensions respecting the original aspect ratio.

##Manipulations::FIT_MAX

The image will be resized to be contained within the given dimensions respecting the original aspect ratio and without increasing the size above the original image size.

##Manipulations::FIT_FILL

Like FIT_CONTAIN the image will be resized to be contained within the given dimensions respecting the original aspect ratio. The remaining canvas will be filled with a background color.

$image
    ->fit(Manipulations::FIT_FILL, 497, 290)
    ->background('007698');

##Manipulations::FIT_STRETCH

The image will be stretched out to the exact dimensions given.

##Manipulations::FIT_CROP

The image will be resized to completely cover the given dimensions respecting the orginal aspect ratio. Some parts of the image may be cropped out.

##Example usage

Image::load('example.jpg')
    ->fit(Manipulations::FIT_STRETCH, 450, 150)
    ->save();

##Crop

By calling the crop method part of the image will be cropped to the given $width and $height dimensions (pixels). Use the $cropMethod to specify which part will be cropped out.

$image->crop(string $cropMethod, int $width, int $height);

The following $cropMethods are available through constants of the Manipulations class:
CROP_TOP_LEFT, CROP_TOP, CROP_TOP_RIGHT, CROP_LEFT, CROP_CENTER, CROP_RIGHT, CROP_BOTTOM_LEFT, CROP_BOTTOM, CROP_BOTTOM_RIGHT.

##Example usage

Image::load('example.jpg')
    ->crop(Manipulations::CROP_TOP_RIGHT, 250, 250)
    ->save();

##Focal crop

The focalCrop method can be used to crop around an exact position. The center of the crop is controlled by the $focalX and $focalY values in percent (0 - 100).

You can also zoom into your focal point, if needed. Zoom is controlled by a floating point ranging from 1 to 100. Each step represents a 100% zoom, so passing 2 will be the same as viewing the image at 200%. The suggested range is 1-10.

$image->focalCrop(int $width, int $height, int $focalX, int $focalY, float $zoom = 1);

##Manual crop

The manualCrop method crops a specific area of the image by specifying the $startX and $startY positions and the crop's $width and $height in pixels.

$image->manualCrop(int $width, int $height, int $x, int $y);

##Example usage

Image::load('example.jpg')
    ->manualCrop(600, 400, 20, 620)
    ->save();
