Paper is a Go library to simulate monochromic old print papers, as shown in the following sample picture.
The Paper struct defined in this library implements the draw.Image interface; i.e. it can be used as a drawing canvas to overlay images and to draw shapes and texts.
Note: The Paper needs to be Mask-ed and Unmask-ed before and after the drawing is done for paper theme to be applied correctly.
import "github.com/aslrousta/paper"
p := paper.New(paper.Nostalgia, 800, 300)
p.Mask()
draw.Draw(p, p.Bounds(), im, image.Point{0, 0}, draw.Src)
p.Unmask()
