* Pageimage objects are usually contained by a `Pageimages` object, which is a type of `Pagefiles` and `WireArray`.
* In addition to the methods and properties below, you'll also want to look at `Pagefile` which this class inherits
* several important methods and properties from.

*
* The default behavior of this method is to simply create and return a new resized version of the image,
* leaving the original in tact. Width and height of the target size are the the first two arguments.
* The third argument called `$options` enables you to modify the default behavior of the size() method
* in various ways. This method only creates the newly sized image once, and then it caches it. Future
* calls simply refer back to the previously resized image.

*
* **About the $options argument**
*
* - If given a *string*, it is assumed to be the value for the "cropping" option.
* - If given an *integer*, it is assumed you are specifying a "quality" value (1-100).
* - If given a *boolean*, it is assumed you are specifying whether or not you want to allow "upscaling".
* - If given an *array*, you may specify any of the options below together:
*
* **All available $options**
*
* - `quality` (int): Quality setting 1-100 (default=90, or as specified in /site/config.php).
* - `upscaling` (bool): Allow image to be upscaled? (default=true).
* - `cropping` (string|bool|array): Cropping mode, see possible values in "cropping" section below (default=center).
* - `suffix` (string|array): Suffix word to identify the new image, or use array of words for multiple (default=none).
* - `forceNew` (bool): Force re-creation of the image even if it already exists? (default=false).
* - `sharpening` (string): Sharpening mode: "none", "soft", "medium", or "strong" (default=soft).
* - `autoRotation` (bool): Automatically correct rotation of images that provide this info? (default=true)
* - `rotate` (int): Rotate the image this many degrees, specify one of: 0, -270, -180, -90, 90, 180, or 270 (default=0).
* - `flip` (string): To flip, specify either "vertical" or "horizontal" (default=none).
* - `hidpi` (bool): Use HiDPI/retina pixel doubling? (default=false).
* - `hidpiQuality` (bool): Quality setting for HiDPI (default=40, typically lower than regular quality setting).
* - `cleanFilename` (bool): Clean filename of historical resize information for shorter filenames? (default=false).
* - `nameWidth` (int): Width to use for filename (default is to use specified $width argument).
* - `nameHeight` (int): Height to use for filename (default is to use specified $height argument).
* - `focus` (bool): Should resizes that result in crop use focus area if available? (default=true).
* In order for focus to be applicable, resize must include both width and height.
* - `allowOriginal` (bool): Return original if already at width/height? May not be combined with other options. (default=false)
* - `webpAdd` (bool): Also create a secondary .webp image variation? (default=false)
* - `webpQuality` (int): Quality setting for extra webp images (default=90).
*
* **Possible values for "cropping" option**
*
* - `true` (bool): Auto detect and allow use of focus (default).
* - `false` (bool): Disallow cropping.
* - `center` (string): to crop to center of image.
* - `x111y222` (string): to crop by pixels, 111px from left and 222px from top (replacing 111 and 222 with your values).
* - `north` (string): Crop North (top), may also be just "n".
* - `northwest` (string): Crop from Northwest (top left), may also be just "nw".
* - `northeast` (string): Crop from Northeast (top right), may also be just "ne".
* - `south` (string): Crop South (bottom), may also be just "s".
* - `southwest` (string): Crop Southwest (bottom left), may also be just "sw".
* - `southeast` (string): Crop Southeast (bottom right), may also be just "se".
* - `west` (string): Crop West (left), may also be just "w".
* - `east` (string): Crop East (right), may alos be just "e".
* - `blank` (string): Specify a blank string to disallow cropping during resize.
* - `array(111,222)` (array): Array of integers index 0 is left pixels and index 1 is top pixels.
* - `array('11%','22%')` (array): Array of '%' appended strings where index 0 is left percent and index 1 is top percent.
*
* **Note about "quality" and "upscaling" options**
*
* ProcessWire doesn't keep separate copies of images with different "quality" or "upscaling" values.
* If you change these and a variation image at the existing dimensions already exists, then you'll still get the old version.
* To clear out an old version of an image, use the `Pageimage::removeVariations()` method in this class before calling
* size() with new quality or upscaling settings.
