Description: The PaintShop Pro Picture Tube file, with the extension .psptube, is a specialized image file format used by Corel's PaintShop Pro, a popular photo editing and graphic design software. Picture Tubes are essentially collections of images or graphics that users can apply with a brush tool to add multiple instances of those images to a project, creating decorative effects, patterns, or scenery. They are often used for adding embellishments, themed graphics, or repeated elements to digital art, scrapbooking, and web design projects. The flexibility and ease of incorporating artistic elements through Picture Tubes make them a favorite among digital artists and hobbyists for enhancing their creations.; 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.
