Description	🔵 The PGM file format was developed in conjunction with the open-source Netpbm graphics program package. Created by Jef Poskanzer in 1988, PGM was designed to store grayscale images and support bitmap images. This file format is compatible with modern graphics editing software such as Corel PaintShop Pro X4, ACDSee Photo Manager 14, and ACD Systems Canvas 15. Since PGM is a plain text format, it can be easily edited using any text editor, making it resistant to changes that can occur when images are transmitted via email. PGM files are classified into two types, distinguished by magic numbers - P2 and P5, which assist graphics editing software in identifying the data encryption standard.
Technical details	🔵 Portable Gray Map Images can be stored with each pixel consuming either 8 or 16 bits of memory space. A PGM file consists of two main sections - the header and the image data. The header begins with a magic number, followed by characters indicating the image width, image height, and maximum grayscale shade value, which should not exceed 65,536. These data are separated by whitespaces. While primarily used on UNIX-based operating systems, the open-source nature of PGM files allows for compatibility with macOS and Windows.

Extension	.mng
Category	🔵 images
Description	🔵 MNG (Multiple-image Network Graphics) is a graphics file format for animated images, similar to GIF but with more advanced features such as support for transparency and alpha channels. MNG files are based on the same chunk structure and compression techniques as PNG (Portable Network Graphics), but allow for multiple images to be included within a single file, each with their own timing and transparency options.
Technical details	🔵 MNG supports both lossless and lossy compression, using the same deflate compression algorithm as PNG. It also includes support for animations, which can include a series of PNG or JPEG images as well as transparency and timing information for each frame. Additionally, MNG can include optional text chunks, which can be used to store metadata or provide additional information about the image. MNG files can be displayed using various software and web browsers that support the format, but support for MNG has been somewhat limited in recent years, with most web browsers only supporting GIF and PNG for animations.
