Mopix

mopix is a lightweight Go library for handling and manipulating PPM (Portable Pixmap) images in the plain-text "P3" format. It provides a clean and modular interface for reading, writing, and transforming images, with support for effects, filters, steganography, drawing, and more.

Features

• Image I/O: Read and write PPM (P3) images easily.
• Filters: Grayscale, sepia, invert

Installation

Install mopix using Go modules:

go get github.com/varun0138/mopix

Then import it in your Go files:

import "github.com/varun0138/mopix"

Notes

• Supports only ASCII (P3) PPM format.
• All operations are done in memory; suitable for small to medium-sized images.
• Written in pure Go with standard library only – no external dependencies.
• Thread-safe operations where applicable.
