Installation

go get -u github.com/rocketlaunchr/showerglass/core

import dataframe "github.com/rocketlaunchr/showerglass/core"

Usage

import	"image/jpeg"
import	"os"
import	"github.com/rocketlaunchr/showerglass/core"

f, err := os.Open("face.jpg")
if err != nil {
	log.Fatalf("Error opening the file: %v", err)
}
defer f.Close()

opts := showerglass.Options{
	NewHeight: 100.0,
	NewWidth:  100.0,
	ResizeAlg: showerglass.CatmullRom,
	TriangleConfig: func(QRank, area int, Q float32, h, w int) *showerglass.Processor {
		if QRank < 1 {
			// only modify first image
			return &showerglass.Processor{
				MaxPoints:  1500,
				BlurRadius: 4,
			}
		}
		return nil
	},
}

masked, _, err := showerglass.FaceMask(f, opts)
if err != nil {
	log.Fatalf("Error aplying filter: %v", err)
}

out, err := os.Create("masked.jpg")
if err != nil {
	log.Fatalf("Error writing the file: %s", err)
}

err = jpeg.Encode(out, masked, &jpeg.Options{Quality: 100})
if err != nil {
	log.Fatalf("Error encoding to file: %s", err)
}
