About:
apngasm is a command-line tool for assembling Animated PNG (APNG) files from individual PNG frames. It provides precise control over frame timing and blending, making it ideal for creating high-quality animations. The tool supports lossless animation creation, ensuring no quality degradation compared to GIF.

Key Features:

Command-line interface for batch processing and automation
Lossless APNG assembly from individual PNG frames
Precise control over frame delays and blending operations
Support for multiple frame disposal methods

Use Cases:

Creating high-quality animated stickers and emojis for web and mobile apps
Converting GIF animations to superior quality APNG format
Automating animation workflows in CI/CD pipelines

Alternatives:

gif2apng – Converts GIF to APNG but lacks apngasm's granular frame control
ffmpeg – More general-purpose but heavier and less specialized for APNG creation
