Introduction to FILTER.js
FILTER.js is an advanced JavaScript library designed to handle image and video processing tasks directly in your web browser or Node.js environment. Leveraging contemporary HTML5 technologies such as Canvas, Web Workers, WebAssembly, and WebGL, FILTER.js allows developers to process multimedia content efficiently. The library is currently at version 1.12.0, with a minimized size of 413 kB.
Key Features
FILTER.js is rich with features, making it a versatile tool for developers looking to integrate multimedia processing capabilities into their applications:
-
Comprehensive Filter Collection: The library offers 14 generic filter types, alongside various plugins and extra filters, enabling both low-level CPU and GPU parallel processing.
-
Advanced Image Class: FILTER.js introduces an
Imageclass that acts as a proxy, streamlining operations on images. -
Flexible and Modular Design: Each filter and plugin in the library can be used independently, allowing for customized builds that fit specific needs.
-
Parallel Processing: The library supports CPU parallel processing using filter workers and GPU parallel processing with GLSL filters, all managed intuitively and transparently. This is beneficial both in browser environments and Node.js.
-
Customizable Builds: Developers can create custom builds of the library by selecting specific filters and plugins, as long as the core classes remain included.
-
Blending and Assembly: Offers image blending modes similar to SVG blend modes and supports fast CPU assembly-coded filters.
Utilization Examples
FILTER.js provides several live examples that showcase its capabilities:
-
