Glitch Images with Go (Golang)

Functions

NewGlitch

gl, err := glitch.NewGlitch("./example.jpg")
if err != nil {
  panic(err)
}

./example.jpg

---

Seed

Glitch is based off of the rand package. Everything parameter is a random value. To seed the random number generator use Seed.

gl.Seed(10)

---

Copy

Copies Input directly to Output with no manipulation. This is a good function to start with

gl.Copy()

---

TransposeInput

gl.TransposeInput()

---

VerticalTransposeInput

VerticalTransposeInput will take random vertical slices of the input, shift them and write them to the output.

gl.VerticalTransposeInput()

---

CompressionGhost

gl.Copy()
gl.CompressionGhost()

---

GhostStreach

gl.Copy()
gl.GhostStreach()

---

HalfLifeLeft

gl.Copy()
gl.HalfLifeLeft()

---

HalfLifeRight

gl.Copy()
gl.HalfLifeRight()

---

ChannelShiftLeft

gl.Copy()
gl.ChannelShiftLeft()

---

ChannelShiftRight

Constants

const MAXC = 1<<16 - 1

MAXC is the maxium value returned by RGBA() will have

Types

type Glitch

type Glitch struct {
	Input  image.Image
	Output draw.Image
	Bounds image.Rectangle
	// contains filtered or unexported fields
}

Glitch represents the two images needed to produce a glitch

func NewGlitch

func NewGlitch(filename string) (*Glitch, error)

NewGlitch creates a new glich from a filename

func (*Glitch) BlueBoost

func (gl *Glitch) BlueBoost()

BlueBoost boost the Blue color of the image

func (*Glitch) ChannelShiftLeft

func (gl *Glitch) ChannelShiftLeft()

ChannelShiftLeft shift all channels left on RGB

func (*Glitch) ChannelShiftRight

func (gl *Glitch) ChannelShiftRight()

ChannelShiftRight shift all channels right on RGB

func (*Glitch) CompressionGhost

func (gl *Glitch) CompressionGhost()

CompressionGhost will compress the image at the lowest value and ghost over it

func (*Glitch) Copy

func (gl *Glitch) Copy()

Copy just takes the image and copies to the output

func (*Glitch) GhostStreach

func (gl *Glitch) GhostStreach()

GhostStreach takes the Output and streches across RGB Alpha is random

func (*Glitch) GreenBoost

func (gl *Glitch) GreenBoost()

GreenBoost boost the Green color of the image

func (*Glitch) HalfLifeLeft

func (gl *Glitch) HalfLifeLeft(strikes, length int)

HalfLifeLeft takes points and drags color Left with a half life.

func (*Glitch) HalfLifeRight

func (gl *Glitch) HalfLifeRight(strikes, length int)

HalfLifeRight takes points and drags color right with a half life. Number of randomply placed streaks

func (*Glitch) Noise

func (gl *Glitch) Noise(r, g, b, a float64)

Noise add random values to the image

func (*Glitch) PrismBurst

func (gl *Glitch) PrismBurst()

PrismBurst spreads channesl around the original image

func (*Glitch) RedBoost

func (gl *Glitch) RedBoost()

RedBoost boost the red color of the image

func (*Glitch) Seed

func (gl *Glitch) Seed(seed int64)

Seed sets the rand Seed

func (*Glitch) SetBounds

func (gl *Glitch) SetBounds(newBounds image.Rectangle)

SetBounds sets the bounds used by the glitch functions

func (*Glitch) TransposeInput

func (gl *Glitch) TransposeInput(height, width int, transpose bool)

TransposeInput moves slices of the image. transpose if true will start with transposing the image

func (*Glitch) VerticalTransposeInput

func (gl *Glitch) VerticalTransposeInput(width, height int, transpose bool)

VerticalTransposeInput moves slices of the image.

func (*Glitch) Write

func (gl *Glitch) Write(out io.Writer) error

func (*Glitch) ZoomColor

func (gl *Glitch) ZoomColor(clrRaw color.Color, maxDistance float64, r int, maxT float64)

ZoomColor expands colors close to color
