The Go port of im2a

An image to ASCII converter, made for 256-color terminals.

Here are some examples:

Source	Default	Grayscale	Pixel	Grayscale + Pixel

Differences from the C++ version

• It's written entirely in Go and does not depend on ImageMagick
• It only supports PNG, JPG & GIF images
• It's somewhat slower
• It handles transparency differently (e.g. rgba(255, 255, 255, 0.5) is represented like rgba(127, 127, 127, 0.5))
