.PNM

📌 The major .PNM container designation relies on storing of the bitmap images composed and opened up in the Portable Any Map pattern, which was initially focused on handling several categories of portable color, grayscale, and monochrome images. Therefore, the .PNM data extension layout may contain raster graphic content in a .PPM, .PGM, or .PBM formation. In addition, the .PNM raster graphics can be stored and opened using ASCII text or binary file variation. As an extra hint, the specified data resources do not employ any compression methods or algorithms and store only one image per file.
