Functions ¶

func BeginFrame ¶

func BeginFrame(graphicsDriver graphicsdriver.Graphics) error

func DumpImages ¶

func DumpImages(graphicsDriver graphicsdriver.Graphics, dir string) (string, error)

func EndFrame ¶

func EndFrame() error

func SwapBuffers ¶ added in v2.7.0

func SwapBuffers(graphicsDriver graphicsdriver.Graphics) error

Types ¶

type Image ¶

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

Image is a rectangle pixel set that might be on an atlas.

func NewImage ¶

func NewImage(width, height int, imageType ImageType) *Image

func (*Image) Deallocate ¶ added in v2.7.0

func (i *Image) Deallocate()

Deallocate deallocates the internal state. Even after this call, the image is still available as a new cleared image.

func (*Image) DrawTriangles ¶

func (i *Image) DrawTriangles(srcs [graphics.ShaderImageCount]*Image, vertices []float32, indices []uint32, blend graphicsdriver.Blend, dstRegion image.Rectangle, srcRegions [graphics.ShaderImageCount]image.Rectangle, shader *Shader, uniforms []uint32, fillRule graphicsdriver.FillRule)

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) DumpScreenshot ¶ added in v2.1.4

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

func (*Image) ReadPixels ¶ added in v2.4.0

func (i *Image) ReadPixels(graphicsDriver graphicsdriver.Graphics, pixels []byte, region image.Rectangle) (ok bool, err error)

func (*Image) WritePixels ¶ added in v2.4.0

func (i *Image) WritePixels(pix []byte, region image.Rectangle)

WritePixels replaces the pixels on the image.

type ImageType ¶ added in v2.4.0

type ImageType int

const (
	ImageTypeRegular ImageType = iota
	ImageTypeScreen
	ImageTypeVolatile
	ImageTypeUnmanaged
)

type Shader ¶

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

var (
	NearestFilterShader *Shader
	LinearFilterShader  *Shader
)

func NewShader ¶

func NewShader(ir *shaderir.Program) *Shader

func (*Shader) Deallocate ¶ added in v2.7.0

func (s *Shader) Deallocate()

Deallocate deallocates the internal state.
