Stream a glob list of PNG files as bitmaps
npm install png-file-streamStream a glob list of PNG files as bitmaps.
Given a glob match specifying a list of PNG images, this will return a readable
stream that will be a Buffer of the raw pixel data. This will be a one dimensional
array of RGBA values.
This module is installed via npm:
`` bash`
$ npm install png-file-stream
Takes a glob match specifying a list of PNG images, and creates an animated GIF using
gifencoder.
` js
var pngFileStream = require('png-file-stream');
var encoder = new GIFEncoder(854, 480);
pngFileStream('test/**/frame?.png')
.pipe(encoder.createWriteStream({ repeat: -1, delay: 500, quality: 10 }))
.pipe(fs.createWriteStream('myanimated.gif')));
`
You can skip the PNG to RAW Pixel Data conversion, by passing an optional "false"
value through:
` js``
var pngFileStream = require('png-file-stream');
pngFileStream('test/**/frame?.png', false)
.pipe(fs.createWriteStream('myconcatendatedpngs.dat')));
