Functions ¶

func ImageFromBytes ¶ added in v0.0.4

func ImageFromBytes(b []byte) (img image.Image, err error)

func ImageFromReader ¶ added in v0.0.4

func ImageFromReader(r io.Reader) (img image.Image, err error)

func MakePhash ¶

func MakePhash(filename string) (b []byte, err error)

func MakeThumb ¶

func MakeThumb(in io.Reader, out io.Writer, maxDimension int) error

func MakeThumbFromFile ¶ added in v0.0.5

func MakeThumbFromFile(filepath string, out io.Writer, maxDimension int) error

func OpenImage ¶

func OpenImage(filename string) (img image.Image, err error)

OpenImage opens a media file from disk and attempts to decode it into an image.Image. If the file is not an image, it will be passed to MakeThumbnail to generate a thumbnail. This function currently only returns thumbnails in case of non StdImage media. Either change the function name or make an ffmpeg command which returns first frame of video/decodes image to jpg.

For this package, this functionality with thumbnails is preferred.

func Phash ¶ added in v0.0.4

func Phash(r io.Reader) (b []byte, err error)

func ReduceImageSize ¶ added in v0.0.4

func ReduceImageSize(img image.Image, w io.Writer, maxDimension int) error

func ResizeImage ¶

func ResizeImage(img image.Image, width, height int) image.Image

ResizeImage resizes the given image to the specified width and height.

func RunFfmpeg ¶

func RunFfmpeg(r io.Reader, w io.Writer, args ...string) error

func SetPhashScale ¶ added in v0.0.4

func SetPhashScale(scale int)

Types ¶

type Phasher ¶ added in v0.0.4

type Phasher struct {
	Scale int
}

func DefaultPhasher ¶ added in v0.0.4

func DefaultPhasher() *Phasher

func (Phasher) GeneratePhash ¶ added in v0.0.4

func (p Phasher) GeneratePhash(img image.Image) []byte

GeneratePhash returns a basic perceptual hash of the given image.
