jello

README

Jello is a GPU-accelerated 2D graphics renderer. It is based heavily on Vello (an experimental 2D graphics rendering engine written in Rust, with a focus on GPU compute), but isn't a direct clone.

Types

type Scene

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

func (*Scene) Append

func (s *Scene) Append(other *Scene, transform curve.Affine)

func (*Scene) ApplyTransform

func (s *Scene) ApplyTransform(transform curve.Affine)

ApplyTransform applies an affine transformation to everything that has already been drawn in the scene. It does not affect future drawing operations.

This can be used, for example, to apply HiDPI scaling.

func (*Scene) Encoding

func (s *Scene) Encoding() *encoding.Encoding

Encoding returns the scene encoding. The scene mustn't be manipulated concurrently with using the encoding.

func (*Scene) Fill

func (s *Scene) Fill(
	style gfx.Fill,
	transform curve.Affine,
	brush gfx.Brush,
	brushTransform curve.Affine,
	path curve.BezPath,
)

func (*Scene) PopLayer

func (s *Scene) PopLayer()

func (*Scene) PushLayer

func (s *Scene) PushLayer(
	blend gfx.BlendMode,
	alpha float32,
	clipTransform curve.Affine,
	clip curve.BezPath,
)

func (*Scene) Reset

func (s *Scene) Reset()

func (*Scene) Stroke

func (s *Scene) Stroke(
	style curve.Stroke,
	transform curve.Affine,
	b gfx.Brush,
	brushTransform curve.Affine,
	shape curve.BezPath,
)
