Mergi Library

Note: Ease function can be applied with any function, in this example it's applied with Watermark function

// Load background and the square images
square, _ := mergi.Import(impexp.NewFileImporter("./testdata/square.jpg"))
bg, _ := mergi.Import(impexp.NewFileImporter("./testdata/white_bg.jpg"))

// Init images frames to add applied ease frames
frames := make([]image.Image, 0)

// Init the limts of the Ease
to := bg.Bounds().Max.X - square.Bounds().Max.X
posY := bg.Bounds().Max.Y/2 - square.Bounds().Max.Y/2
speed := 4

// Ease from 0 to width of background
for i := 0; i < to; i += speed {
  // Apply Easeing function InBounce
  posX := mergi.Ease(float64(i), 0, float64(to), mergi.InBounce)
  img, _ := mergi.Watermark(square, bg, image.Pt(int(posX), posY))
  frames = append(frames, img)
}

// For preview example, save as a gif
gif, _ := mergi.Animate(frames, 1)
mergi.Export(impexp.NewAnimationExporter(gif, "out.gif"))
