Using djpeg:
<lang go>package main
// Files required to build supporting package raster are found in:
// * Bitmap
// * Read a PPM file
// * Write a PPM file
import (
"raster"
"exec"
"fmt"
)
func main() {
// (A file with this name is output by the Go solution to the task
// "Bitmap/PPM conversion through a pipe," but of course any handy
// jpeg should work.)
c := exec.Command("djpeg", "pipeout.jpg")
pipe, err := c.StdoutPipe()
if err != nil {
fmt.Println(err)
return
}
err = c.Start()
if err != nil {
fmt.Println(err)
return
}
b, err := raster.ReadPpmFrom(pipe)
if err != nil {
fmt.Println(err)
return
}
err = b.WritePpmFile("pipein.ppm")
if err != nil {
fmt.Println(err)
}
}</lang>
