Functions

func BeginFrame added in v1.10.0

func BeginFrame() error

func DumpImages added in v1.10.0

func DumpImages(dir string) error

func EndFrame added in v1.10.0

func EndFrame() error

func SetGraphicsDriver added in v1.10.0

func SetGraphicsDriver(graphics driver.Graphics)

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) DrawTriangles added in v1.10.0

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 added in v1.10.0

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

func (*Image) Fill added in v1.9.0

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

func (*Image) MarkDisposed added in v1.10.0

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 added in v1.12.0

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

func (*Image) ReplacePixels

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

func (*Image) SetVolatile added in v1.12.0

func (i *Image) SetVolatile(volatile bool)

type Shader added in v1.12.0

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

func NewShader added in v1.12.0

func NewShader(program *shaderir.Program) *Shader

func (*Shader) MarkDisposed added in v1.12.0

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)
