func Restore() error

Types

type Image

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

Image represents an image that can be restored when GL context is lost.

func NewImage

func NewImage(width, height int, filter opengl.Filter, volatile bool) *Image

func NewImageFromImage

func NewImageFromImage(source *image.RGBA, width, height int, filter opengl.Filter) *Image

func NewScreenFramebufferImage

func NewScreenFramebufferImage(width, height int) *Image

func (*Image) At

func (p *Image) At(x, y int) (color.RGBA, error)

At returns a color value at (x, y).

Note that this must not be called until context is available.

func (*Image) BasePixelsForTesting

func (p *Image) BasePixelsForTesting() []uint8

func (*Image) Dispose

func (p *Image) Dispose()

func (*Image) DrawImage

func (p *Image) DrawImage(img *Image, vertices []float32, colorm *affine.ColorM, mode opengl.CompositeMode)

func (*Image) Fill

func (p *Image) Fill(clr color.RGBA)

func (*Image) IsInvalidated

func (p *Image) IsInvalidated() bool

func (*Image) ReplacePixels

func (p *Image) ReplacePixels(pixels []uint8)

func (*Image) Size

func (p *Image) Size() (int, int)
