Features

• After Effects Renderers - Plays animations exported from Adobe After Effects using a dedicated plugin, preserving complex motion and effects.
• Exporter Plugins - Provides a dedicated After Effects plugin that creates PAG files directly from compositions.
• Animation File Loaders - Loads a Portable Animated Graphics file from a source and prepares it for playback.
• Animation Layer Image Swappers - Swaps images within PAG animation layers at runtime for dynamic content personalization.
• Export Pipelines - Provides an export pipeline from Adobe After Effects that produces compact PAG files for cross-platform playback.
• Feature-Comprehensive Exporters - Exports animations supporting all After Effects features, including vector, raster, and third-party plugin effects.
• After Effects Exporters - Exports animations from Adobe After Effects as PAG files for cross-platform playback.
• Animated Image Manipulation - Swaps images within a PAG file at runtime using the PAGImage class.
• Layer Editors - Modifies layer structure, merges files, and swaps text or images in PAG animations at runtime.
• Canvas Rendering - Draws the current frame of a PAG animation onto a provided canvas surface.
• Layer Content Editors - Enables runtime editing of text, images, and layer structure in PAG animations without re-exporting from After Effects.
• Hardware-Accelerated Rendering - Ships a GPU-accelerated rendering pipeline using OpenGL, Metal, and Vulkan for real-time cross-platform playback.
• Animation Layer Compositing - Combines image, text, and solid layers within a PAG composition to build complex visual sequences.
• Editable Layer Trees - Provides a layer-based composition engine that manages editable text, image, shape, and solid layers with independent animation properties.
• Layer Accessors and Mutators - Accesses and manipulates individual layers within a PAG composition, including image, text, shape, and solid layers.
• PAG Format Decoders - Reads PAG files ten times faster than JSON with fifty percent smaller file sizes for the same animation.
• Efficient Animation Decoders - Reads PAG files ten times faster than JSON and reduces file size by about fifty percent for the same animation.
• JSON Animation Rendering - Plays vector and raster animations from PAG files in real time across mobile, desktop, and web platforms.
• Canvas Frame Renderers - Draws each frame of a loaded PAG animation onto a canvas surface for real-time display.
• Native Animation Renderers - Renders vector and raster animations from PAG files natively in real time across iOS, Android, desktop, and web.
• Animation SDK Integrations - Embeds the PAG rendering library into mobile, desktop, or web applications to play animations.
• Animation Binary Decoders - Reads a compact binary format that stores vector and raster layers with animation timelines in a single portable container.
• Runtime Object Mutators - Provides runtime mutation of animation layers, allowing image replacement, text editing, and composition merging during playback.
• Animation Layer Mutators - Enables runtime replacement of images, text, and layer merging in animations without re-exporting from After Effects.
• Cross-Platform Abstraction Layers - Provides a unified C++ rendering core with platform-specific bindings for iOS, Android, desktop, and web.
• Animated Graphics - Renders and plays PAG animation files in real time on iOS, Android, macOS, Windows, Linux, and Web.
• Animation Playback Controls - Renders a PAG animation frame by frame, controlling playback with standard media controls.
• Interactive Playback - Provides programmatic start, stop, seek, and loop controls for interactive animation playback.
• Progressive Render Animations - Loads and renders PAG animation files in real time across multiple platforms and devices.
• Cross-Platform Animation Engines - Plays vector and raster animations on iOS, Android, desktop, and web without additional runtimes.
• Cross-Platform Animation Players - Renders PAG animation files on iOS, Android, macOS, Windows, Linux, and Web without additional runtime dependencies.
• Cross-Platform Rendering - Renders After Effects animations natively from the PAG file format with real-time playback across platforms.
• Disk - Stores decoded animation frames as sequential image files on disk to reduce memory usage and accelerate repeated playback.
• Bitmap Fallback Renderers - Converts unsupported After Effects effects into pre-rendered bitmap sequences for playback.
• Callback-Based Exporters - Exports PAG compositions to video or other formats through a callback-based export interface.
• Composition Video Exporters - Converts PAG compositions into video or other formats using configurable export settings.
• Vector - Exports animations as vector PAG files for small file size and preserved editability in UI animations.
• Embedded Audio Decoders - Decodes audio samples embedded in PAG files for synchronized playback or export.
• Playback Event Hooks - Ships callback hooks for reacting to animation playback state changes and user interactions.
• Animation Bitmap Exporters - Exports animations as bitmap PAG files that support all After Effects features at the cost of larger file size.
• Effect Fallback Renderers - Converts unsupported After Effects effects into pre-rendered bitmap sequences for playback.
• Video Export Pipelines - Converts PAG compositions into video files through a movie exporter interface.
• Animation Frame Extractors - Extracts individual frames from a PAG animation for custom processing or display.
• Mixed Format Exporters - Exports animations with mixed vector and bitmap layers to balance editability and feature support.
• Animation Audio Track Readers - Reads and processes audio samples embedded in PAG animations.
• Preview and Optimization Tools - Ships a desktop and web preview tool for inspecting animations, replacing assets, viewing performance metrics, and optimizing file size.
• Animation Video Swappers - Swaps video content within a PAG animation at runtime for dynamic playback.
• Animation Placeholder Swappers - Swaps placeholder images or videos in PAG animation layers to preview visual content substitutions in real time.
• Template Text Editors - Modifies text content and styling within PAG animation layers to preview dynamic text replacements.
• Runtime Animation Editors - Modifies text, images, and layer structure in PAG animations during playback without re-exporting from After Effects.
