Mask will be resized to the current image size. By default a greyscale version of the mask is converted to alpha values, but you can set mask_with_alpha to apply the actual alpha channel. Any transparency values of the current image will be maintained. @method \Intervention\Image\Image opacity(integer $transparency) Set the opacity in percent of the current image ranging from 100% for opaque and 0% for full transparency. @method \Intervention\Image\Image orientate() This method reads the EXIF image profile setting 'Orientation' and performs a rotation on the image to display the image correctly. @method mixed pickColor(integer $x, integer $y, string $format = 'array') Pick a color at point x, y out of current image and return in optional given format. @method \Intervention\Image\Image pixel(mixed $color, integer $x, integer $y) Draw a single pixel in given color on x, y position. @method \Intervention\Image\Image pixelate(integer $size) Applies a pixelation effect to the current image with a given size of pixels. @method \Intervention\Image\Image polygon(array $points, \Closure $callback = null) Draw a colored polygon with given points.

An anchor can be defined to determine from what point of the image the resizing is going to happen. Set the mode to relative to add or subtract the given width or height to the actual image dimensions. You can also pass a background color for the emerging area of the image. @method mixed response(string $format = null, integer $quality = 90) Sends HTTP response with current image in given format and quality. @method \Intervention\Image\Image rotate(float $angle, string $bgcolor = '#000000') Rotate the current image counter-clockwise by a given angle. Optionally define a background color for the uncovered zone after the rotation. @method \Intervention\Image\Image sharpen(integer $amount = 10) Sharpen current image with an optional amount. Use values between 0 and 100. @method \Intervention\Image\Image text(string $text, integer $x = 0, integer $y = 0, \Closure $callback = null) Write a text string to the current image at an optional x,y basepoint position.
