Convert PNG ANIMATED to SGI

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 SGI file extension stands for Silicon Graphics Image, a raster graphics file format developed by Silicon Graphics Inc. primarily for their IRIS workstations. This format, originating in the late 1980s, supports uncompressed and RLE-compressed data with up to 48-bit color (16 bits per channel for RGB) and an alpha channel. SGI files are widely utilized in 3D graphics, visualization, and high-end imaging due to their ability to store high-quality images and intricate details, making them an essential asset in professional graphics and animation industries.
