Из PPM в DDS

PPM is an image file format that is included in the Netpbm open source graphics editor. This graphic format is convenient and simple. Other Netpbm formats that have found widespread use are PBM, i.e. Portable Bitmap, as well as PGM, i.e. Portable Graymap. This three graphic formats are sometimes referred to as PNM, i.e. Portable Format Anymap. PGM stores grayscale images. PMP is a collection of color images, which are intermediate files that are used when converting formats not so well known, using Portable Bitmap Utilities. And PPM files are mainly used on UNIX platforms that are based on Intel. These files are categorized as bitmap images. This is a 24-bit color image that has been formatted in text format. Takes every pixel with a number from zero to 65536 for storage. The color of the pixel is determined by the number. Contains data spaces, the height and width of the character, the maximum color values. Portable Pixmap uses an uncompressed low-performance format that can be compared with other bitmap image formats. This explains its rare use in order to store large images.

DDS is a graphic format, bitmap image. DDS stands for Abbreviation for the DirectDraw Surface. This format, developed by Microsoft, is usually used to store textures for 3D environments (for example, in computer games or 3D models, including new-generation game consoles). The format is designed specifically for use in the Microsoft DirectX environment, however, in OpenGL, the use of DDS files is also possible. Even when compressed, the texture quality is preserved in the DDS files. Compression of files of this format is possible using DirectX Texture Compression technology.
