Constants

const MaxCountForShare = 10

MaxCountForShare represents the time duration when the image can become shared.

This value is exported for testing.

func BeginFrame

func BeginFrame() error

func DumpImages

func DumpImages(dir string) error

func EndFrame

func EndFrame() error

func SetGraphicsDriver

func SetGraphicsDriver(graphics driver.Graphics)

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) DrawTriangles

func (i *Image) DrawTriangles(srcs [graphics.ShaderImageNum]*Image, vertices []float32, indices []uint16, colorm *affine.ColorM, mode driver.CompositeMode, filter driver.Filter, address driver.Address, sourceRegion driver.Region, subimageOffsets [graphics.ShaderImageNum - 1][2]float32, shader *Shader, uniforms []interface{})

DrawTriangles draws triangles with the given image.

The vertex floats are:

0: Destination X in pixels
1: Destination Y in pixels
2: Source X in pixels (the upper-left is (0, 0))
3: Source Y in pixels
4: Color R [0.0-1.0]
5: Color G
6: Color B
7: Color Y

func (*Image) Dump

func (i *Image) Dump(path string, blackbg bool) error

func (*Image) Fill

func (i *Image) Fill(clr color.RGBA)

func (*Image) MarkDisposed

func (i *Image) MarkDisposed()

MarkDisposed marks the image as disposed. The actual operation is deferred. MarkDisposed can be called from finalizers.

A function from finalizer must not be blocked, but disposing operation can be blocked. Defer this operation until it becomes safe. (#913)

func (*Image) Pixels

func (img *Image) Pixels(x, y, width, height int) ([]byte, error)

func (*Image) ReplacePixels

func (i *Image) ReplacePixels(pix []byte)

func (*Image) SetVolatile

func (i *Image) SetVolatile(volatile bool)

type Shader

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

func NewShader

func NewShader(program *shaderir.Program) *Shader

func (*Shader) MarkDisposed

func (s *Shader) MarkDisposed()

MarkDisposed marks the shader as disposed. The actual operation is deferred. MarkDisposed can be called from finalizers.

A function from finalizer must not be blocked, but disposing operation can be blocked. Defer this operation until it becomes safe. (#913)
