What is the difference between .iris and .png?

Description: The Iris Graphics file type, commonly associated with the extension .iris, originates from Silicon Graphics for use on their workstations. It is designed for storing high-quality images, particularly in the field of computer graphics and 3D rendering. This file format is tailored to support complex visual data, accommodating a range of color depths and resolutions suitable for professional graphics work. Despite its specialized use, the Iris Graphics format is less common today, having been superseded by more versatile image formats.; A PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
