A printed circuit board Gerber and drill file plotter. Implemented as a Node transform stream that consumes objects output by gerber-parser and outputs PCB image objects.

Part of the [tracespace][] collection of PCB visualization tools.

install

``shell
npm install --save gerber-plotter


or


yarn add gerber-plotter
`

gerber-parser is a peer dependency, so you probably want to install it too:

`shell
npm install --save gerber-parser


or


yarn add gerber-parser
`

Or, use a script tag:

`html


`

example

`js
var fs = require('fs')
var gerberParser = require('gerber-parser')
var gerberPlotter = require('gerber-plotter')

var parser = gerberParser()
var plotter = gerberPlotter()

plotter.on('warning', function(w) {
console.warn('plotter warning at line ' + w.line + ': ' + w.message)
})

plotter.once('error', function(e) {
console.error('plotter error: ' + e.message)
})

fs.createReadStream('/path/to/gerber/file.gbr')
.pipe(parser)
.pipe(plotter)
.on('data', function(obj) {
console.log(JSON.stringify(obj))
})
`

To run this module in a browser, it should be bundled with a tool like [browserify][] or [webpack][]. If you are using the script tag installation method instead, there will be a global variable gerberPlotter available after you have included gerber-plotter.min.js`.
