func (EXR) Float32

func (e EXR) Float32() (EXR, error)

type Encoder

type Encoder interface {
	RawEncoder
	Encoder() RawEncoder
	EncodeBytes(img image.Image) ([]byte, error)
	EncodeFFMPEG(img image.Image) ([]string, error)
}

type FFMPegSession

type FFMPegSession struct {
	RenderStreamBase
	// contains filtered or unexported fields
}

FFMPegSession handles sending frames to FFMPeg

func (*FFMPegSession) Close

func (s *FFMPegSession) Close() error

type FFMPegSessionSource

type FFMPegSessionSource interface {
	Encoder
	EncodeFFMPEG(img image.Image) ([]string, error)
}

type FrameSession

type FrameSession struct {
	RenderStreamBase
}

FrameSession handles sending frames to individual images on disk

func (*FrameSession) Close

func (s *FrameSession) Close() error

Close closes the FrameSession. Normally this is handled by try-resources

type ImageCodec

type ImageCodec interface {
	Read(fileName string) (image.Image, error)
	Write(string, image.Image) error
	// contains filtered or unexported methods
}

type Iterator

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

Iterator is returned by a renderer to handle spanning over a range of TimeCode's. Unlike the iterator returned by TimeCode, this one does not advance the TimeCode when Next() is called as that's done when writing an image.

func (*Iterator) HasNext

func (i *Iterator) HasNext() bool

func (*Iterator) Next

func (i *Iterator) Next() interface{}

func (PNG) Encoder

func (_ PNG) Encoder() RawEncoder
