### Initialize and Render GIF with gif.js Source: https://github.com/jnordberg/gif.js/blob/master/README.md This JavaScript snippet demonstrates how to initialize a GIF encoder, add frames from various sources (image, canvas, or context), and render the GIF. It also shows how to handle the 'finished' event to get the generated GIF blob. ```javascript var gif = new GIF({ workers: 2, quality: 10 }); // add an image element gif.addFrame(imageElement); // or a canvas element gif.addFrame(canvasElement, {delay: 200}); // or copy the pixels from a canvas context gif.addFrame(ctx, {copy: true}); gif.on('finished', function(blob) { window.open(URL.createObjectURL(blob)); }); gif.render(); ``` -------------------------------- ### Jinja2 HTML Template for Project Page Source: https://github.com/jnordberg/gif.js/blob/master/site/templates/test.html This template defines the basic structure for a project page, extending a base layout. It uses Jinja2 syntax to dynamically insert a page title, main HTML content, and a highlighted code block from a `script.source` variable, typically used for displaying code examples. ```Jinja2 {% extends 'layout.html' %} {% set script = contents.tests\[page.metadata.script\] %} {% block scripts %} {% endblock %} {% block body %}\n\n{{ page.title }}\n----------------\n\n{{ page.html }}\n\nSource\n------\n\n `{{ hljs.highlightAuto(script.source).value }}`\n\n{% endblock %} ``` -------------------------------- ### Initialize and Render GIF with gif.js Source: https://github.com/jnordberg/gif.js/blob/master/site/contents/code.md This snippet demonstrates the basic workflow for creating a GIF using the GIF.js library. It covers initializing the GIF object with worker and quality settings, adding frames from an image element, a canvas element with a delay, or directly from a canvas context. It also shows how to register a callback for the 'finished' event to open the generated GIF blob in a new window, and finally, how to trigger the rendering process. ```javascript var gif = new GIF({ workers: 2, quality: 10 }); // add a image element gif.addFrame(imageElement); // or a canvas element gif.addFrame(canvasElement, {delay: 200}); // or copy the pixels from a canvas context gif.addFrame(ctx, {copy: true}); gif.on('finished', function(blob) { window.open(URL.createObjectURL(blob)); }); gif.render(); ``` -------------------------------- ### gif.js Constructor and setOptions Parameters Source: https://github.com/jnordberg/gif.js/blob/master/README.md This section details the configuration options available for the gif.js constructor or the `setOptions` method. These options control aspects like GIF repetition, quality, worker count, background color, dimensions, transparency, and dithering. ```APIDOC GIF Constructor/setOptions: repeat: number (Default: 0) Description: Repeat count. -1 = no repeat, 0 = forever. quality: number (Default: 10) Description: Pixel sample interval. Lower is better. workers: number (Default: 2) Description: Number of web workers to spawn. workerScript: string (Default: 'gif.worker.js') Description: URL to load worker script from. background: string (Default: '#fff') Description: Background color where source image is transparent. width: number | null (Default: null) Description: Output image width. If null, image size will be determined by first frame added. height: number | null (Default: null) Description: Output image height. If null, image size will be determined by first frame added. transparent: string | null (Default: null) Description: Transparent hex color, e.g., 0x00FF00 = green. dither: string | boolean (Default: false) Description: Dithering method. Available methods: FloydSteinberg, FalseFloydSteinberg, Stucki, Atkinson. Can add '-serpentine' for serpentine scanning. debug: boolean (Default: false) Description: Whether to print debug information to console. ``` -------------------------------- ### HTML Structure for Video to GIF User Interface Source: https://github.com/jnordberg/gif.js/blob/master/site/contents/tests/video.md Defines the essential HTML elements for a web page that facilitates video to GIF conversion. It includes an input range for controlling a parameter (e.g., quality or duration), a button to trigger the conversion, a status display, a video player with multiple source options, and an image tag to show the final GIF result. ```HTML

It's designed for web page tracking. ```JavaScript (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); ga('create', 'UA-41063995-1', 'jnordberg.github.io'); ga('send', 'pageview'); ``` -------------------------------- ### HTML Placeholder for Canvas Rendering Output Source: https://github.com/jnordberg/gif.js/blob/master/site/contents/tests/canvas.md This HTML snippet provides a basic structure for a web page intended to display the output of a canvas rendering process. It includes a paragraph element to show a 'Loading...' message and an image tag where the final rendered image (e.g., a GIF) would be displayed. ```HTML

``` -------------------------------- ### gif.js addFrame Method Options Source: https://github.com/jnordberg/gif.js/blob/master/README.md This section describes the specific options that can be passed to the `addFrame` method when adding an image or canvas element to the GIF. These options control frame-specific properties like delay, pixel data copying, and disposal method. ```APIDOC addFrame Options: delay: number (Default: 500) Description: Frame delay in milliseconds. copy: boolean (Default: false) Description: Copy the pixel data. dispose: number (Default: -1) Description: Frame disposal code. See GIF89a Spec. ``` === COMPLETE CONTENT === This response contains all available snippets from this library. No additional content exists. Do not make further requests.
