Create a new project that will be using the canvas library:
mkdir project
cd project
go mod init
go get -u github.com/tdewolff/canvasCreate main.go with the following contents:
package main
import (
"github.com/tdewolff/canvas"
"github.com/tdewolff/canvas/renderers"
)
func main() {
// Create new canvas of dimension 100x100 mm
c := canvas.New(100, 100)
// Create a canvas context used to keep drawing state
ctx := canvas.NewContext(c)
// Create a triangle path from an SVG path and draw it to the canvas
triangle, err := canvas.ParseSVGPath("L60 0L30 60z")
if err != nil {
panic(err)
}
ctx.SetFillColor(canvas.Mediumseagreen)
ctx.DrawPath(20, 20, triangle)
// Rasterize the canvas and write to a PNG file with 3.2 dots-per-mm (320x320 px)
if err := renderers.Write("getting-started.png", c, canvas.DPMM(3.2)); err != nil {
panic(err)
}
}We run the basic template which will output a file getting-started.png.
go run main.go
