`public`	# `__construct( mixed $filename = null )` Overrides `Object::__construct`
`public`	# `setGD( mixed $gd )`
`public`	# `getGD( )`
`public static`	# `set_default_quality( GD::$quality $quality )` Set the default image quality. Set the default image quality. Parameters `$quality` quality int A number from 0 to 100, 100 being the best quality.
`public`	# `setQuality( mixed $quality )` Set the image quality, used when saving JPEGs. Set the image quality, used when saving JPEGs.
`public`	# `croppedResize( mixed $width, mixed $height )` Resize an image to cover the given width/height completely, and crop off any overhanging edges. Resize an image to cover the given width/height completely, and crop off any overhanging edges.
`public`	# `fittedResize( mixed $width, mixed $height )` Resizes the image to fit within the given region. Behaves similarly to paddedResize but without the padding. Resizes the image to fit within the given region. Behaves similarly to paddedResize but without the padding.
`public`	# `hasGD( )`
`public`	# `resize( mixed $width, mixed $height )` Resize an image, skewing it as necessary. Resize an image, skewing it as necessary.
`public GD`	# `rotate( angle $angle )` Rotates image by given angle. Rotates image by given angle. Parameters `$angle` angle Returns `GD` GD
`public GD`	# `rotatePixelByPixel( angle $angle )` Rotates image by given angle. It's slow because makes it pixel by pixel rather than using built-in function. Used when imagerotate function is not available(i.e. Ubuntu) Rotates image by given angle. It's slow because makes it pixel by pixel rather than using built-in function. Used when imagerotate function is not available(i.e. Ubuntu) Parameters `$angle` angle Returns `GD` GD
`public GD`	# `crop( top $top, left $left, GD::$width $width, GD::$height $height )` Crop's part of image. Crop's part of image. Parameters `$top` top y position of left upper corner of crop rectangle `$left` left x position of left upper corner of crop rectangle `$width` width rectangle width `$height` height rectangle height Returns `GD` GD
`public integer`	# `getWidth( )` Method return width of image. Method return width of image. Returns `integer` width.
`public integer`	# `getHeight( )` Method return height of image. Method return height of image. Returns `integer` height
`public`	# `resizeByWidth( mixed $width )` Resize an image by width. Preserves aspect ratio. Resize an image by width. Preserves aspect ratio.
`public`	# `resizeByHeight( mixed $height )` Resize an image by height. Preserves aspect ratio Resize an image by height. Preserves aspect ratio
`public`	# `resizeRatio( mixed $maxWidth, mixed $maxHeight, mixed $useAsMinimum = false )` Resize the image by preserving aspect ratio. By default, it will keep the image inside the maxWidth and maxHeight Passing useAsMinimum will make the smaller dimension equal to the maximum corresponding dimension Resize the image by preserving aspect ratio. By default, it will keep the image inside the maxWidth and maxHeight Passing useAsMinimum will make the smaller dimension equal to the maximum corresponding dimension
`public static`	# `color_web2gd( mixed $image, mixed $webColor )`
`public`	# `paddedResize( GD::$width $width, GD::$height $height, backgroundColour $backgroundColor = "FFFFFF" )` Resize to fit fully within the given box, without resizing. Extra space left around the image will be padded with the background color. Resize to fit fully within the given box, without resizing. Extra space left around the image will be padded with the background color. Parameters `$width` width `$height` height `$backgroundColor` backgroundColour
`public`	# `greyscale( mixed $rv = 38, mixed $gv = 36, mixed $bv = 26 )` Make the image greyscale $rv = red value, defaults to 38 $gv = green value, defaults to 36 $bv = blue value, defaults to 26 Based (more or less entirely, with changes for readability) on code from http://www.teckis.com/scriptix/thumbnails/teck.html Make the image greyscale $rv = red value, defaults to 38 $gv = green value, defaults to 36 $bv = blue value, defaults to 26 Based (more or less entirely, with changes for readability) on code from http://www.teckis.com/scriptix/thumbnails/teck.html
`public`	# `makeDir( mixed $dirname )`
`public`	# `writeTo( mixed $filename )`
