Functions ¶

func DrawShapes ¶

func DrawShapes(img draw.Image, x, y int, shapes ...Shaper) error

func FilledImage ¶

func FilledImage(width, height int, fill color.Color) draw.Image

func SaveImage ¶

func SaveImage(img image.Image, filename string) error

Types ¶

type Circle ¶

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

The zero value is invalid! Use NewCircle() to create a valid Circle.

func NewCircle ¶

func NewCircle(fill color.Color, radius int) *Circle

By calling newShape() we pass on any checking to newShape() without having to know what if any is required.

func (*Circle) Draw ¶

func (circle *Circle) Draw(img draw.Image, x, y int) error

func (Circle) Fill ¶

func (shape Circle) Fill() color.Color

func (*Circle) Radius ¶

func (circle *Circle) Radius() int

func (*Circle) SetFill ¶

func (shape *Circle) SetFill(fill color.Color)

func (*Circle) SetRadius ¶

func (circle *Circle) SetRadius(radius int)

func (*Circle) String ¶

func (circle *Circle) String() string

type CircularShaper ¶

type CircularShaper interface {
	Shaper // Fill(); SetFill(); Draw()
	Radius() int
	SetRadius(radius int)
}

type Option ¶

type Option struct {
	Fill   color.Color
	Radius int
	Rect   image.Rectangle
	Filled bool
}

type Rectangle ¶

type Rectangle struct {
	image.Rectangle
	// contains filtered or unexported fields
}

The zero value is invalid! Use NewRectangle() to create a valid Rectangle.

func NewRectangle ¶

func NewRectangle(fill color.Color, rect image.Rectangle) *Rectangle

func (*Rectangle) Draw ¶

func (rectangle *Rectangle) Draw(img draw.Image, x, y int) error

x, y are the top-left (for radius-based shapes they are the middle)

func (Rectangle) Fill ¶

func (shape Rectangle) Fill() color.Color

func (*Rectangle) Filled ¶

func (rectangle *Rectangle) Filled() bool

func (*Rectangle) Rect ¶

func (rectangle *Rectangle) Rect() image.Rectangle

func (*Rectangle) SetFill ¶

func (shape *Rectangle) SetFill(fill color.Color)

func (*Rectangle) SetFilled ¶

func (*Rectangle) SetRect ¶

func (rectangle *Rectangle) SetRect(rect image.Rectangle)

type RectangularShaper ¶

type RectangularShaper interface {
	Shaper // Fill(); SetFill(); Draw()
	Rect() image.Rectangle
	SetRect(image.Rectangle)
	Filled() bool
	SetFilled(bool)
}

type RegularPolygon ¶

type RegularPolygon struct {
	*Circle
	// contains filtered or unexported fields
}

The zero value is invalid! Use NewRegularPolygon() to create a valid RegularPolygon.

func NewRegularPolygon ¶

func NewRegularPolygon(fill color.Color, radius, sides int) *RegularPolygon

func (*RegularPolygon) Draw ¶

func (polygon *RegularPolygon) Draw(img draw.Image, x, y int) error

func (RegularPolygon) Fill ¶

func (*RegularPolygon) SetSides ¶

func (polygon *RegularPolygon) SetSides(sides int)

func (*RegularPolygon) Sides ¶

func (polygon *RegularPolygon) Sides() int

func (*RegularPolygon) String ¶

func (polygon *RegularPolygon) String() string

type RegularPolygonalShaper ¶

type RegularPolygonalShaper interface {
	CircularShaper // Fill(); SetFill(); Draw(); Radius(); SetRadius()
	Sides() int
	SetSides(sides int)
}

type Shaper ¶

type Shaper interface {
	Fill() color.Color
	SetFill(fill color.Color)
	Draw(img draw.Image, x, y int) error
}

func New ¶

func New(shape string, option Option) (Shaper, error)
