Types

type Mipmap

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

Mipmap is a set of buffered.Image sorted by the order of mipmap level. The level 0 image is a regular image and higher-level images are used for mipmap.

func New

func New(width, height int, imageType atlas.ImageType) *Mipmap

func (*Mipmap) Deallocate

func (m *Mipmap) Deallocate()

func (*Mipmap) DrawTriangles

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

func (*Mipmap) DumpScreenshot

func (m *Mipmap) DumpScreenshot(graphicsDriver graphicsdriver.Graphics, name string, blackbg bool) (string, error)

func (*Mipmap) ReadPixels

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

func (*Mipmap) WritePixels

func (m *Mipmap) WritePixels(pix []byte, region image.Rectangle)
