Description	🔵 The PNM (Portable Any Map) format is a group of image file formats used for portable images, which are maps of pixel values that can represent grayscale or color data. The PNM format family consists of three types of file formats: PBM (Portable BitMap), PGM (Portable GrayMap), and PPM (Portable PixMap).
Technical details	🔵 In PBM format, pixel values are binary, with each pixel represented by a single bit. A value of 0 represents black, and a value of 1 represents white. Each row of pixel data is stored as a sequence of bits, padded to the nearest byte. In PGM format, pixel values are grayscale, with each pixel represented by a single byte. The pixel data is stored as a sequence of bytes, with each row of pixel data stored contiguously. In PPM format, pixel values are in color, with each pixel represented by three bytes representing the red, green, and blue components. The pixel data is stored as a sequence of triples of bytes, with each row of pixel data stored contiguously. PNM files can be easily converted between the three formats, as well as to and from other image file formats using various software tools.

Description	🔵 Computer Graphics Metafile is explicitly used as a format for storing and sharing positional graphics while retaining the details and quality of the image irrespective of the technological platform or device on which it is utilized. The CGM format has been in use as far back as 1986 when it was first released. Unlike some image formats that handle two-dimensional positional image, or bitmap image alone, CGM supports both. Image files are saved as CGM when highly fine details are essential. Such applications include structure design images in aviation, engineering, and other similar technical fields.
Technical details	🔵 With most graphics applications used for computer-aided design and detailed simulation of engineering designs, CGM is the most prolific file format for archiving such works. CGM is a metafile file format that permits representing all graphical elements of an image in a plain-text, binary, or character-based source document. Each of the mentioned CGM source data representation comes with its merit. Binary coded CGM files are accessible for programs to decode and analyze. Character-based CGM files produce the smallest file size, relative to the other encoding methods, forthwith becomes the fastest to transfer. Plain-text CGM files have the advantage of being editable with any text editor.
