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)

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)
