addAlpha
Adds an opaque alpha component if the image is in RGB format and does not already contain one. Returns self.
averageColor
Returns the average RGB color of all pixels in the image.
baselineHeight
Returns the pixel height (relative to the bottom of the image) which first contains a non-white pixel or -1 if
no baseline is found.
bounds(cutoff)
Returns an object continaing the bounds of the image. Cutoff is max bound color value for any color component.
If it is negative, it is the min bound color value.
componentCount
Returns the number of color components in the receiver as a Number.
crop(x, y, width, height)
Crops the image to the specified values. Returns self.
Raises an exception on error.
data
Returns a Buffer primitive containing the image data (loading it first if needed).
Manipulating this data will affect what is drawn when the receiver's draw method is called.
decodingHeightHint
Returns the decoding height hint.
decodingWidthHint
Returns the decoding width hint.
encodingQuality
Returns the encodingQuality setting.
error
Returns a String containing the current error or nil if there is no error.
flipX
Flips the image on the horizonal plane (left/right mirror). Returns self.
flipY
Flips the image on the vertical plane (top/bottom mirror). Returns self.
height
Returns the image hieght.
isL8
Returns true if the receiver is in L8 (8bit Luminance) format, false otherwise.
isLA8
Returns true if the receiver is in LA8 (8bit Luminance-Alpha) format, false otherwise.
isRGB8
Returns true if the receiver is in RGB8 format, false otherwise.
isRGBA8
Returns true if the receiver is in RGBA8 format, false otherwise.
open(optionalPathString)
Sets the path to optionalPathString if provided and opens the image file.
Returns self on success, Nil on failure.
path
Returns the image path.
removeAlpha
Removes the alpha component if the image contains one. Returns self.
resizedTo(newWidth, newHeight)
Scales the image up to newWidth x newHeight. Returns the newly scaled image.
resizedTo(width, height)
Returns a new image of the receiver resized to the given width and height.
Raises an exception on error.
save(optionalPathString)
Sets the path to optionalPathString if provided and saves the image
in the format specified by the path extension. Returns self on success, nil on failure.
setDataWidthHeightComponentCount(aSequence, width, height, componentCount)
Sets the image data and its parameters. Returns self.
setDecodingHeightHint(width)
Sets the decoding height hint. Returns self.
setDecodingWidthHint(width)
Sets the decoding width hint. Returns self.
setEncodingQuality(aNumber)
Sets the image encoding quality (range is 0.0 - 1.0, 1.0 with being the highest).
setPath(aString)
Sets the image path. Returns self.
width
Returns the image width.
