/**
* This is a method that combines resize, crop and paste methods in order to generate a thumbnail from the given image.
* The benefit of using this function is that the function can automatically combine crop and resize methods together
* with the pad feature in order to generate the thumb.
*
* @param int $width Thumb width.
* @param int $height Thumb height.
* @param bool|string $cropOrPad If you set this to 'crop' the method will first resize the image to preserve the
* aspect ratio and then it will crop the extra pixels to fit the defined width and height.
* If you set this to 'pad' the method will first do the resize and than
* it wil create a blank image that has the size of defined width and height and fill it
* with $padColor, then it will paste the resized image in the center of the new image.
* @param null|string $padColor Parameter that fills the background with the defined color.
* Following formats are acceptable
* - "fff"
* - "ffffff"
* - array(255,255,255)
*
* @return $this
