Types ¶
type FloatNRGBA ¶
type FloatNRGBA struct {
// Pix holds the image's pixels, in R, G, B, A order. The pixel at
// (x, y) starts at Pix[(y-Rect.Min.Y)*Stride + (x-Rect.Min.X)*4].
Pix []float64
// Stride is the Pix stride (in bytes) between vertically adjacent pixels.
Stride int
// Rect is the image's bounds.
Rect image.Rectangle
}
FloatNRGBA represents an image made up of FloatNRGBA colour information.
func NewFloatNRGBA ¶
func NewFloatNRGBA(r image.Rectangle) *FloatNRGBA
NewFloatNRGBA returns a new FloatNRGBAImage image with the given bounds.
func (*FloatNRGBA) Bounds ¶
func (f *FloatNRGBA) Bounds() image.Rectangle
func (*FloatNRGBA) ColorModel ¶
func (f *FloatNRGBA) ColorModel() color.Model
func (*FloatNRGBA) FloatNRGBAAt ¶
func (f *FloatNRGBA) FloatNRGBAAt(x, y int) colour.FloatNRGBA
func (*FloatNRGBA) PixOffset ¶
func (f *FloatNRGBA) PixOffset(x, y int) int
PixOffset returns the index of the first element of Pix that corresponds to the pixel at (x, y).
