Constants

const MaxCountForShare = 10

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

This value is exported for testing.

Functions

func BeginFrame

func BeginFrame() error

func DumpImages

func DumpImages(dir string) error

func EndFrame

func EndFrame() error

func MakeImagesSharedForTesting

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 (i *Image) At(x, y int) (byte, byte, byte, byte)

func (*Image) ClearFramebuffer

func (i *Image) ClearFramebuffer()

ClearFramebuffer clears the image with a color. This affects not only the (0, 0)-(width, height) region but also the whole framebuffer region.

func (*Image) Dispose

func (i *Image) Dispose()

func (*Image) DrawTriangles

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

func (*Image) Dump

func (i *Image) Dump(path string) error

func (*Image) Fill

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

func (*Image) IsSharedForTesting

func (i *Image) IsSharedForTesting() bool

func (*Image) IsVolatile

func (i *Image) IsVolatile() bool

func (*Image) MakeVolatile

func (i *Image) MakeVolatile()

func (*Image) PutVertex

func (i *Image) PutVertex(dst []float32, dx, dy, sx, sy float32, bx0, by0, bx1, by1 float32, cr, cg, cb, ca float32)

PutVertices puts the given dst with vertices that can be passed to DrawTriangles.

func (*Image) ReplacePixels

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

func (*Image) Size

func (i *Image) Size() (width, height int)
