Functions

func BeginFrame

func BeginFrame(graphicsDriver graphicsdriver.Graphics) error

func EndFrame

func EndFrame(graphicsDriver graphicsdriver.Graphics) error

Types

type Image

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

func NewImage

func NewImage(width, height int) *Image

func NewScreenFramebufferImage

func NewScreenFramebufferImage(width, height int) *Image

func (*Image) At

func (img *Image) At(graphicsDriver graphicsdriver.Graphics, x, y int) (r, g, b, a byte, err error)

func (*Image) DrawTriangles

func (i *Image) DrawTriangles(srcs [graphics.ShaderImageNum]*Image, vertices []float32, indices []uint16, colorm affine.ColorM, mode graphicsdriver.CompositeMode, filter graphicsdriver.Filter, address graphicsdriver.Address, dstRegion, srcRegion graphicsdriver.Region, subimageOffsets [graphics.ShaderImageNum - 1][2]float32, shader *Shader, uniforms [][]float32, evenOdd bool)

DrawTriangles draws the src image with the given vertices.

Copying vertices and indices is the caller's responsibility.

func (*Image) DumpScreenshot

func (*Image) MarkDisposed

func (i *Image) MarkDisposed()

func (*Image) ReplacePixels

func (i *Image) ReplacePixels(pix []byte, x, y, width, height int)

ReplacePixels replaces the pixels at the specified region.

func (*Image) SetIndependent

func (i *Image) SetIndependent(independent bool)

func (*Image) SetVolatile

func (i *Image) SetVolatile(volatile bool)

type Shader

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

func NewShader

func NewShader(ir *shaderir.Program) *Shader

func (*Shader) MarkDisposed

func (s *Shader) MarkDisposed()
