magpie

magpie is a high-performance, expressive image blending and composition library in pure Go.

Installation

go get github.com/blazeroni/magpie

Quick Start

Here's a simple example of blending two images using the Multiply blend mode.

package main

import (
	"image"
	"log"

	"github.com/blazeroni/magpie/pkg/blend"
	"github.com/blazeroni/magpie/pkg"
)

func main() {
	// 1. Load destination and source images.
	dst := loadImage("background.png")
	src := loadImage("foreground.png")

	// 2. Define the blend operation.
	op := blend.Multiply()

	// 3. Apply the operation.
	output, err := magpie.Draw(dst, dst.Bounds(), src, image.Point{}, op, magpie.ToNewImage())
	if err != nil {
		log.Fatal(err)
	}

	// 4. Save the output.
	saveImage("output.png", output)
}

API Concepts

• magpie.Draw: The primary entry point for all drawing operations.
• op.Op: Defines the operation to be performed (e.g., op.BlendOp, op.CompositeOp).
• magpie.Context: For advanced use cases, a Context can be created to control concurrency and other settings.

Note

The project is still in early stages. Breaking API changes may occur leading up to a stable release.

Future

• Improve README & project documentation
• Benchmarks and comparisons with other libraries
• Additional image processing operations
  • HSV blending
  • Point operations: (effects, filters, etc.)
  • Convolutions: (blur, sharpen, etc.)
• Additional optimizations
