This is the format that is used in the OpenGL and Microsoft DirectX development environment. It is used to store bitmap images of user interface environments and textures. It allows you to store information in compressed and uncompressed forms. It is used for texturing game models and storing entire textural arrays to create games and 3D-software applications. DDS is used to develop the latest-generation video game consoles. It makes it possible to compress texture blocks 'on the fly', which increases performance when you run the application.
This is a file used for creating line plots in the form of vector images. They include text objects, splines, forms, arcs, lines and arrows. It can contain a set of colors, images and sketches. It was initially developed for the Xfig drawing program, but today it’s used in other drawing editors.
