Functions

func Copy

func Copy(dst draw.Image, src image.Image, blind bool) error

Copies an Image using one thread.

func CopyMT

func CopyMT(dst draw.Image, src image.Image, blind bool, nthreads int) error

Copies an Image using multiple threads. The images should be thread-safe.

func Operate

func Operate(o Operator, r image.Rectangle)

Performs the Task 'o' on every Pixel within the Rectangle 'r'.

func OperateMT

func OperateMT(o Operator, r image.Rectangle, nthreads int)

Performs the Task 'o' on every Pixel within the Rectangle 'r'. This implementation uses multiple threads, so the Task should be threadsafe.

Types

type Operator

type Operator interface {
	Operate(pt image.Point)
}
