Types

type CorrectionProcessor

type CorrectionProcessor struct {
	imageserver_image.Processor
	// contains filtered or unexported fields
}

CorrectionProcessor is a Processor that corrects gamma.

func NewCorrectionProcessor

func NewCorrectionProcessor(prc imageserver_image.Processor, enabled bool) *CorrectionProcessor

NewCorrectionProcessor creates a CorrectionProcessor.

func (*CorrectionProcessor) Process

func (prc *CorrectionProcessor) Process(nim image.Image, params imageserver.Params) (image.Image, error)

Process implements Processor.

type Processor

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

Processor is a Processor that applies gamma transformation.

func NewProcessor

func NewProcessor(gamma float64, highQuality bool) *Processor

NewProcessor creates a Processor.

func (*Processor) Change

func (prc *Processor) Change(params imageserver.Params) bool

Change implements Processor.

func (*Processor) Process

func (prc *Processor) Process(nim image.Image, params imageserver.Params) (image.Image, error)

Process implements Processor. It doesn't return error.
