SpriteMap

SpriteMap helps you to extract sprites out of a sprite map.

imageAt(point: CGPoint, size: CGSize) -> CGImage?

Returns an optional CGImage.

Provide the coordinates as CGPoint and the size of your single sprite as CGSize.

To get the last image of a sprite map with the size of 600 × 600 pixels containing 9 sprites (3 × 3), you write:

let sprite = spriteMap.imageAt(point: CGPoint(x: 2, y: 2), size: CGSize(width: 200, height: 200))

imageAt(index: Int, size: CGSize) -> CGImage?`

Returns an optional CGImage.

Provide the index as Int and the size of your single sprite as CGSize.

To get the last image of a sprite map with the size of 600 × 600 pixels containing 9 sprites (3 × 3), you write:

let sprite = spriteMap.imageAt(index: 8, size: CGSize(width: 200, height: 200))

mergeImages(_ images: [CGImage]) -> CGImage?`

Returns an optional CGImage.

Takes multiple CGImage elements and merges them into one.

Useful when you have multiple parts as sprites (body, mouth, eyes).

let image = CGImage.mergeImages([bodyImage, mouthImage, eyesImage])

CGImage.mergeImages()
