What is the difference between .sdg and .png?

Description: The SDG file type is associated with StarOffice Gallery, a component of StarOffice Suite, which was an office suite developed by Sun Microsystems. It is primarily used to store collections of images, graphics, and themes that can be inserted into documents and presentations created within the StarOffice suite. SDG files serve as libraries or galleries from which users can easily access and manage pre-defined or custom multimedia content to enhance their documents. Although StarOffice has evolved into OpenOffice and later LibreOffice, SDG files represent a legacy format for organizing and utilizing graphical resources in office documents.; 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.
