Types

type Image

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

func NewImage

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

func (*Image) Deallocate

func (i *Image) Deallocate()

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 *atlas.Shader, uniforms []uint32, fillRule graphicsdriver.FillRule)

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) ReadPixels

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

func (*Image) WritePixels

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

WritePixels replaces the pixels at the specified region.
