✍ Bitmap font loader library for Go.

This library loads font data from an image ("bitmap").
It gets loaded into a Go map which means a Glyph can be retrieved with font[glyph], for example font["A"].

Example

bm := bitmap.New()
font := bm.Load("font.png")

x := 0
y := 0
	
xx := x
yy := y
ch := font[glyph]
for i := 0; i < ch.Height; i++ {
 	bin := ch.Data[i] // Gets a line: a glyph is 8x8
 	binarr := strings.Split(bin, "")

 	for _, pix := range binarr {
 		if pix == "1" { draw(xx, yy) }
	 	xx += 1
	}
	yy += 1
	xx = x
}
