Functions ¶

func DrawCompositePoints ¶

func DrawCompositePoints(inpVec [][]types.Vector2d, col [4]byte) (*image.RGBA, error)

DrawCompositePoints takes a composite shape and draws it.

func DrawFillCompositePoints ¶

func DrawFillCompositePoints(inpVec [][]types.Vector2d, col [4]byte) (*image.RGBA, error)

DrawFillCompositePoints takes a composite and draws a filled one

func DrawFillCompositeShape ¶

func DrawFillCompositeShape(shape types.RenderableComposite, col [4]byte) (*image.RGBA, error)

DrawFillCompositeShape takes a renderable shape and draws a filled version

func DrawPoints ¶

func DrawPoints(inp []types.Vector2d, col [4]byte) *image.RGBA

DrawPoints draws the points provided as an image.

func FillShape ¶

func FillShape(img *image.RGBA, col [4]byte)

FillShape uses even-odd rule to fill a space within colored points. It screws up on shapes with insets, but technically they're no longer One shape so that is expected behavior.

func ScanLineFill ¶

func ScanLineFill(img *image.RGBA, startX int, endX int, y int, col [4]byte)

ScanLineFill assumes X and Y are valid and does some kind of messy pointer manipulations in order to reduce the amount of work required to fill the image.
