Fork of https://github.com/winkerVSbecks/angular-pdf-viewer, npm package for webpack.
An AngularJS directive to display PDFs. DEMO
Dependencies
Usage
- Add as dependency
npm install @cpcwood/angular-pdf-viewer
yarn add @cpcwood/angular-pdf-viewer
- Ensure AngularJS peer dependency is met
- Import in client
import '@cpcwood/angular-pdf-viewer'
- Include the lib as a dependency in your angular app:
var app = angular.module('app', ['pdf']);
Directive
The URL, request headers, scale and delegate-handle can be set using the attributes:
<pdf-viewer
delegate-handle="my-pdf-container"
url="pdfUrl"
scale="1"
show-toolbar="true"
headers="{ 'x-you-know-whats-awesome': 'EVERYTHING' }"></pdf-viewer>
Delegate Service (pdfDelegate)
The pdfDelegate service allows you to access and control individual instances of a directive. This allows us to have multiple instances of the same directive in the same controller.
Inject the pdfDelegate
service into your controller. You can then fetch an instance using it's delegate handle and call methods on it:
pdfDelegate.$getByHandle('my-pdf-container').zoomIn();
The following methods are available to the delegate:
- prev
- next
- zoomIn(amount) default amount = 0.2
- zoomOut(amount) default amount = 0.2
- zoomTo(amount)
- rotate (clockwise by 90 degrees)
- getPageCount
- getCurrentPage
- goToPage(pageNumber)
- load
Change the PDF File
In order to replace the active PDF with another one, you can call the load
method of the delegate. For example:
pdfDelegate
.$getByHandle('my-pdf-container')
.load('url-of-the-new-file.pdf');
Development & Example
- Install:
yarn install
- Start development server:
yarn start
- Visit app:
http://localhost:8080
Toolbar
The default toolbar can be shown or hidden using the show-toolbar
attribute. Since the PDF can be easily controlled using the delegate service it's quite trivial to build a custom toolbar. Or place the toolbar on a separate scope.
