func EndFrame() error

Types

type Image

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

func NewImage

func NewImage(width, height int, volatile bool) *Image

func NewScreenFramebufferImage

func NewScreenFramebufferImage(width, height int) *Image

func (*Image) At

func (i *Image) At(x, y int) (r, g, b, a byte, err error)

func (*Image) DrawImage

func (i *Image) DrawImage(src *Image, bounds image.Rectangle, a, b, c, d, tx, ty float32, colorm *affine.ColorM, mode driver.CompositeMode, filter driver.Filter)

func (*Image) DrawTriangles

func (i *Image) DrawTriangles(src *Image, vertices []float32, indices []uint16, colorm *affine.ColorM, mode driver.CompositeMode, filter driver.Filter, address driver.Address)

DrawTriangles draws the src image with the given vertices.

Copying vertices and indices is the caller's responsibility.
