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, imageType atlas.ImageType) *Image

func (*Image) DrawTriangles

func (i *Image) DrawTriangles(srcs [graphics.ShaderImageCount]*Image, vertices []float32, indices []uint16, blend graphicsdriver.Blend, dstRegion, srcRegion graphicsdriver.Region, subimageOffsets [graphics.ShaderImageCount - 1][2]float32, shader *Shader, uniforms []uint32, evenOdd bool)

DrawTriangles draws the src image with the given vertices.

Copying vertices and indices is the caller's responsibility.

func (*Image) DumpScreenshot

func (i *Image) DumpScreenshot(graphicsDriver graphicsdriver.Graphics, name string, blackbg bool) (string, error)

func (*Image) MarkDisposed

func (i *Image) MarkDisposed()

func (*Image) ReadPixels

func (i *Image) ReadPixels(graphicsDriver graphicsdriver.Graphics, pixels []byte, x, y, width, height int) error

func (*Image) WritePixels

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

WritePixels replaces the pixels at the specified region.

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()
