Description🔵 PGM file format was developed alongside the open-source Netpbm package of graphics program. Developed by Jef Poskanzer in 1988, PGM was a format for storing grayscale images and supporting bitmap. The PGM file format is forward compatible with recent graphics editing software like Corel PaintShop Pro X4, ACDSee Photo Manager 14, and ACD Systems Canvas 15. Being a plain text format, PGM can be edited using any available text editor, and thus survives the quintessential changes that image files undergo when transmitted via email. PGM files come in two types, only differentiated by magic numbers – P2 and P5, which helps graphics editor software identify the data encryption standard.
Technical details🔵 Portable Gray Map Images can be stored away with each pixel taking up memory space of either 8 or 16 bits. There are two major sections in the plain text string of a PGM file – the header and image data. The header starts with the magic number, followed by characters indicating image width, image height, maximum grayscale shade value – never exceeding 65.536, all sandwiched by whitespaces. Though used mainly on the UNIX-based operating system, being open-source has earned the PGM file compatibility with macOS and Windows.

Description🔵 .jpeg (Joint Photographic Experts Group) The .jpeg format, also known as JPG, is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photographyThe degree of compression can be adjusted, allowing for a selectable tradeoff between storage size and image quality. JPEG is the most common image format used by digital cameras and other photographic image capture devices; it is the most common format for storing and transmitting photographic images on the World Wide Web.
Technical details🔵 The JPEG (.jpeg or .jpg) format, created by the Joint Photographic Experts Group, is widely used for digital photography and online images. It employs lossy compression, reducing file size by omitting some image data, allowing a balance between size and quality. JPEG usually uses the YCbCr color model (8 bits per channel) and supports sRGB color space, RGB, and CMYK models. Compression levels are adjustable, affecting both size and quality: higher compression decreases size and quality, while lower compression increases both. JPEG images can be scaled down with minimal quality loss but scaling up can degrade quality. The format supports extensive metadata and offers progressive JPEGs for gradual loading on slow connections. Widely compatible, JPEG is ideal for photographs but less so for sharp contrast images like line drawings or text. Each re-save degrades quality slightly due to its lossy nature. This format's understanding is vital for those involved in photography, graphic design, web development, or any digital image-related field.
