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.
