You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: doc.go
    path of file: ./repos/triangle
    
    the code of the file until where you have to start completion: /*
Package triangle is an image processing library which converts images to computer generated art using delaunay triangulation.

The package provides a command
    
	func main() {
		p := &triangle.Processor{
			// Initialize struct variables
		}

		img := &triangle.Image{*p}
		_, _, _, err := img.Draw(srcImg, p, func() {})
		if err != nil {
			fmt.Printf("Error on triangulation process: %s", err.Error())
		}
	}
