eiv (extensible image viewer)

eiv is a GUI image viewer written in Go that is extensible with plugins. By default it supports gif, jpeg, png, bmp, ccitt, tiff, vp8, vp8l, and webp.

Installation

go get -u github.com/patrickmcnamara/eiv

Usage

eiv $IMAGEFILENAME

Plugins

To create a plugin for eiv for an image format abc, create (or download) a library that can decode that format into an image.Image in Go and register the format in the init function of your library. Next, create a package main program in Go that imports your library and does not have a main function. Build this using the plugin build mode for Go with an output name with the extension .eivp (e.g. go build -buildmode=plugin -o abc.eivp). Put this plugin into your config directory under $CONFIGDIR/eiv/plugin. Voilà. eiv can now display your images.
