Types

type ResizeProcessor

type ResizeProcessor struct {
	DefaultResampling gift.Resampling
	MaxWidth          int
	MaxHeight         int
}

ResizeProcessor is a imageserver/image.Processor implementation that resizes the Image with GIFT.

All params are extracted from the "gift_resize" node param and are optionals:

• width
• height
• mode: resize mode possible values:
• <no value> (default): see github.com/disintegration/gift.Resize
• fit: see github.com/disintegration/gift.ResizeToFit
• fill: see github.com/disintegration/gift.ResizeToFill
• resampling: resampling method possible values:
• nearest_neighbor (default)
• box
• linear
• cubic
• lanczos

func (*ResizeProcessor) Change

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

Change implements imageserver/image.Processor.

func (*ResizeProcessor) Process

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

Process implements imageserver/image.Processor.

type RotateProcessor

type RotateProcessor struct {
	DefaultInterpolation gift.Interpolation
}

RotateProcessor is a imageserver/image.Processor implementation that rotates the Image with GIFT.

func (*RotateProcessor) Change
