Functions ¶

func Clamp ¶

func Clamp[T cmp.Ordered](value, mn, mx T) T

func IntersectNRGBA ¶

func IntersectNRGBA(dst *image.NRGBA, r image.Rectangle, src *image.NRGBA, sp image.Point, out *image.NRGBA, op image.Point) image.Rectangle

func IntersectRGBA ¶

func IntersectRGBA(dst *image.RGBA, r image.Rectangle, src *image.RGBA, sp image.Point, out *image.RGBA, op image.Point) image.Rectangle

func IsColorModelSupported ¶

func IsColorModelSupported(model color.Model) bool

func Iterate ¶

func Iterate[T image.Image](pixIter PixelIterator, pixCalc PixCalculator[T], fn func(dst, src, out []uint8)) T

Types ¶

type Config ¶

type Config interface {
	PixelIterator() PixelIterator
	DefaultOutputMode() DefaultOutputMode
	DefaultColorModel() color.Model
}

type DefaultOutputMode ¶

type DefaultOutputMode int

const (
	DefaultOutputToDst DefaultOutputMode = iota
	DefaultOutputToNewImage
)

func (DefaultOutputMode) ToOutputMode ¶

func (m DefaultOutputMode) ToOutputMode() OutputMode

type Output ¶

type Output interface {
	OutputMode() OutputMode
	ColorModel() color.Model
	ProvidedImage() (image.Image, image.Point)
}

func ToDst ¶

func ToDst() Output

func ToImage ¶

func ToImage(img image.Image, pt image.Point) Output

func ToNewImage ¶

func ToNewImage() Output

func ToNewNRGBAImage ¶

func ToNewNRGBAImage() Output

func ToNewRGBAImage ¶

func ToNewRGBAImage() Output

type OutputMode ¶

type OutputMode int

const (
	OutputToDst OutputMode = iota
	OutputToNewImage
	OutputToProvidedImage
)

type ParallelPixelIterator ¶

type ParallelPixelIterator struct {
	// contains filtered or unexported fields
}

ParallelPixelIterator iterates over a PixRowCalculator in parallel with the specified concurrency.

func NewParallelPixelIterator ¶

func NewParallelPixelIterator(concurrency int) ParallelPixelIterator

NewParallelPixelIterator creates a new ParallelPixelIterator. Concurrency specifies the number of goroutines to use for parallel processing. Each iteration will create its own set of goroutines, so concurrently processing multiple images will result in multiple sets of goroutines.

func (ParallelPixelIterator) Iterate ¶

func (ppi ParallelPixelIterator) Iterate(pixCalc PixRowCalculator, fn func(dst, src, out []uint8))

type PixCalculator ¶

type PixCalculator[T image.Image] interface {
	PixRowCalculator
	Result() T
}

func NewPixCalculatorNRGBA ¶

func NewPixCalculatorNRGBA(dst *image.NRGBA, r image.Rectangle, src *image.NRGBA, srcPt image.Point, out *image.NRGBA, outPt image.Point) PixCalculator[*image.NRGBA]

func NewPixCalculatorRGBA ¶

func NewPixCalculatorRGBA(dst *image.RGBA, r image.Rectangle, src *image.RGBA, srcPt image.Point, out *image.RGBA, outPt image.Point) PixCalculator[*image.RGBA]

type PixRowCalculator ¶

type PixRowCalculator interface {
	Rect() image.Rectangle
	Calculate(row int) (dst, src, out []uint8)
}

type PixelIterator ¶

type PixelIterator interface {
	Iterate(pixCalc PixRowCalculator, fn func(dst, src, out []uint8))
}

func NewPixelIterator ¶

func NewPixelIterator(concurrency int) PixelIterator

type SerialPixelIterator ¶

type SerialPixelIterator struct{}

SerialPixelIterator iterates over a PixRowCalculator in serial with no concurrency.

func NewSerialPixelIterator ¶

func NewSerialPixelIterator() SerialPixelIterator

NewSerialPixelIterator creates a new SerialPixelIterator.

func (SerialPixelIterator) Iterate ¶

func (i SerialPixelIterator) Iterate(pixCalc PixRowCalculator, fn func(dst, src, out []uint8))
