imaging

A little image processing library written in Go

Overview

imaging is a small image processing library written in Go. You can use this library in your code by importing it as a package, or you can use the CLI directly by cloning this repo and compiling the program. There is also a template for deploying the code to AWS, which allows you to use the functions in a web browser.

Dist

dist generates a "distance image" which is a grayscale image where each pixel's luminance is relative the center of the image. These types of images can be useful anytime you need a quick test image as a placeholder.

Try this in your browser imaging.micahwalter.com/dist?width=800&height=400. You can adjust the width and height.

Steps

steps generates a "step wedge" test image. These types of test images can be useful when calibrating a camera system.

Try this in your browser imaging.micahwalter.com/steps?width=800&height=400. You can adjust the width and height.
