Angular Thumbnail

AngularJS thumbnail service to generate blob or base64 data as well as directive to display an image as thumbnail in canvas. Perfect for an Ionic app.

Demo

http://kennyki.github.io/angular-thumbnail

Possible Usage

  1. Generate thumbnail for pictures from gallery/camera to store locally or remotely in PhoneGap/cordova apps. You don't need a plugin for that.
  2. Display thumbnail for pictures from gallery/local db in a list in PhoneGap/cordova apps. Because CSS resizing on many pictures can be very consuming.
  3. Resizing before upload to a server.

Anti-pattern

  1. Generating thumbnails from large images in a desktop web application.
    • first of all, CSS resizing (setting width and height) should be sufficient as most of the desktop will have enough power to do it. But:
    • consider requesting for smaller images from the server.
    • if the images are external you should cache them in your own server and resize them there.

Installation

  1. Install through bower bower install angular-thumbnail or download the package manually.
  2. In your index.html, import:
    1. canvas-to-blob.min.js only if you need to generate blob data
    2. angular-thumbnail.min.js
  3. Add dependency to your module angular.module('', ['ui.thumbnail']);
  4. Enable CORS <access origin="*"/> in the config.xml

API

Configurations

angular.module('', ['ui.thumbnail'])

.config(function(ThumbnailServiceProvider) {
  // otherwise both defaults to 100
  ThumbnailServiceProvider.defaults.width = 150;
  ThumbnailServiceProvider.defaults.height = 150;
})

;

Directive

Hmm.. it's clearer in the demo's source code.

Service

A ThumbnailService dependency can be injected into a controller.

ThumbnailService.generate(src, opts)

  • Parameters:

    • src: either a url or base64 string
    • opts: an optional object of
      • width: number (defaults to 100)
      • height: number (defaults to 100)
      • returnType: 'blob' (defaults to 'base64')
      • type: 'image/jpeg' (defaults to 'image/png')
      • noDistortion: boolean. If true, the image will not get distorted. (defaults to false)
      • encoderOptions: A number between 0 and 1 indicating image quality if the requested type is 'image/jpeg' or 'image/webp'.
  • Returns: a promise that resolves with a base64 string or blob
