Running my gotour pic tutorial for an image of size 256x256, sometimes pic.ShowImage doesn't actually show the full image. It'll show an image of a smaller size (about 256x160) and print the rest of the data as an ASCII parsed string. Other times it shows the full 256x256 image.

Code below:

package main

import (
"golang.org/x/tour/pic"
"image"
"image/color"
)

type Image struct {
W, H int
}

func (i Image) ColorModel() color.Model {
return color.RGBAModel
}

func (i Image) Bounds() image.Rectangle {
return image.Rect(0, 0, i.W, i.H)
}

func (i Image) At(x, y int) color.Color {
return color.RGBA{uint8(x^y), uint8(x*y), uint8((x+y)/2), 255}
}

func main() {
m := Image{256, 256}
pic.ShowImage(m)
}
