API

var filmstrip2gif = require('filmstrip2gif')

filmstrip2gif(imgUrl, duration, numFrames, isHorizontal, cb)

Convert an image located at imgUrl (with known total duration duration and number of frames numFrames, assumed to be evenly distributed) to an animated GIF, calling cb when done. cb is a function(err, gifBlob). If isHorizontal is true, the filmstrip will be sliced into numFrames pieces horizontally, vertically otherwise.
