Convert PNG ANIMATED to CALS

Animated PNG is a file extension for animated raster graphics. Developed as an extension of the Portable Network Graphics (PNG) format, Animated PNG allows for animation while maintaining PNG's lossless compression and transparency features. Introduced by Mozilla in 2004, it initially garnered limited support but gained traction for its compatibility and efficiency. Animated PNG is ideal for web usage, offering animation without the substantial file size of GIFs, making it suitable for high-quality web animations and UI elements.

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
