-#### Missing Features
+pdfjs 1.0.0-alpha.1 (still in development; expected to be buggy) contains a rewritten layout engine (layout engine of pdfjs `<=0.5` reached its limits), i.e., both API and layout behavior has changed completely. Install with:

 ```
 
-### new Document(font)
+### Features

+## MIT License
 
-### .text(text[, opts])
+Copyright (c) 2013-2015 Markus Ast
 
-**Arguments:**
-
-- **text** - the text that should be rendered
-- **opts** - text options
-
-**Options:**
-
-- **bold** - whether the text should be rendered bold (default: false)
-- **italic** - whether the text should be rendered italic  (default: false)
-- **light** - whether the text should be rendered light (default: false)
-- **align** - the text alignment (default: left, available: left, right, center or justify)
-- **lineSpacing** - this is a factor that could be used to increase or decrease the line spacing (default: 1)
-- **font** - the font that should be used
-- **size** - the font size
-
-**Example:**
-
-```js
-doc.text('Lorem ipsum dolor sit amet ...', {
-  size: 12,
-  align: 'justify',
-  lineSpacing: 1.2
-})
-```
-
-### .text([definition])
-
-This text method can be used to render more advanced/complex text fragments. It allows to combine multiple text styles. **Returns** a [Text](#text) function.
-
-**Arguments:**
-
-- **definition** - a function describing the text to be rendered; it gets the `text` object described in [Text](#text)
-
-**Example:**
-
-```js
-doc.text(function(text) {
-  // this === text
-  this.opts.size = 12
-  this.opts.lineSpacing = 1.35
-  text('This is a header', { bold: true, size: 18 }).br()
-  text('Content can be')('bold', { bold: true })
-  text(',')('italic', { italic: true })
-  text('or')('both', { italic: true, bold: true })('.')
-  text('You`re also able to use')('light', { light: true })
-  text(', which could be')('italic', { italic: true, light: true })(', too.').br()
-  text('If you want, you can also')('mixup different fonts', { font: sourceCodeProp })
-  text('or different')('font', { size: 10 })('sizes', { size: 16 })('.')
-})
-```

-
-### .image(buffer, [opts])
-
-This method can be used to render an image.
-
-**Arguments:**

-- **wrap** - whether the image should wrap surrounding text (default: true)
-- **align** - when `wrap` is set to `true`, `align` can be used to set the horizontal positon (left, right, or center)
-- **x**, **y** - when `wrap` is set to `false`, `x` and `y` can be used to explicitly set the position if the image
-
-**Example:**

-
-### .text()
-
-Same as [doc.text(text[, opts])](#texttext-opts)
-
-### .br()
-
-Line Break. Returns the [Text](#text) function.
-
-### .pageNumber()
-
-Print the page number the text fragment is rendered on. Returns the [Text](#text) function.
-
-**Example:**

-
-## Table
-
-This table object is used to define its rows and its behaviour on page breaks.

-
-This method is used to define a table row. **Returns** a [Table Row](#table-row) object.
-
-**Arguments:**
-
-- **opts** - row options

-
-**Options:**
-
-- **borderWidth** -
-- + [Text Options](#texttext-opts)
-
-### .beforeBreak([opts,] definition)
-
-Same as [.tr([opts,] definition)](#tropts-definition), but only rendered if the table is broken among two pages. This row is then rendered directly before the page break.
-
-```js
-table.beforeBreak(function() {
-  this.td('Subtotal:', { colspan: 4, align: 'right' })
-  this.td(function() {
-    this.text(function(text) {
-      this.opts.align = 'right'
-      this.opts.size  = 11
-      text(function() {
-        if (!this.table) return ''
-        return items.subtotalUntil(this.table.row)
-      })
-    })
-  })
-})
-```
-
-### .afterBreak([opts,] definition)

-
-```js
-table.afterBreak(function() {
-  this.td('Carryover:', { colspan: 4, align: 'right' })
-  this.td(function() {
-    this.text(function(text) {
-      this.opts.align = 'right'

-      })
-    })

-**Result:**
-
-![Result](https://raw.github.com/rkusa/pdfjs/gh-pages/images/table-pagebreak-example.png)

-
-## Font
-
-### new Font(buffer)
-
-Create a new font from the given buffer.
-
-### new Font(styles)
-
-Instead of just providing one font style (*regular*), you can also provide multiple styles.
-
-**Styles:** *normal*, *italic*, *bold*, *boldItalic*, *light*, *lightItalic*
-
-**Example:**
-
-```js
-new pdfjs.Font({
-  regular: fs.readFileSync(__dirname + '/open-sans/OpenSans-Regular.ttf'),
-  bold: fs.readFileSync(__dirname + '/open-sans/OpenSans-Bold.ttf'),
-  boldItalic: fs.readFileSync(__dirname + '/open-sans/OpenSans-BoldItalic.ttf'),
-  light: fs.readFileSync(__dirname + '/open-sans/OpenSans-Italic.ttf'),
-  italic: fs.readFileSync(__dirname + '/open-sans/OpenSans-LightItalic.ttf'),
-  lightItalic: fs.readFileSync(__dirname + '/open-sans/OpenSans-LightItalic.ttf'),
-})
-```
-
-(the sync API is just used for presentation purpose and should not be used in production)
-
-In the browser, you can load fonts using AJAX requests, e.g.:
-
-```js
-function load(path, callback) {
-  var request = new XMLHttpRequest()
-  request.open('GET', path, true)
-  request.responseType = 'arraybuffer'
-
-  if (request.overrideMimeType) {
-      request.overrideMimeType('text/plain; charset=x-user-defined')
-  } else {
-      request.setRequestHeader('Accept-Charset', 'x-user-defined')
-  }
-
-  request.onload = function() {
-    if (request.status === 200) {
-      callback(null, request.response)
-    } else {
-      callback(request.status)
-    }
-  }
-
-  request.send(null)
-}
-
-load('path/to/font.ttf', function(err, buffer) {
-  // ...
-})
-```
