| 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 | 🔵 .xcf (eXperimental Computing Facility) The .xcf format is the native image file format of the GIMP software (GNU Image Manipulation Program). It's used for storing the entire composition including layers, channels, paths, and other elements that are part of a GIMP image. The XCF format is designed to preserve all information GIMP can contain about an image; however, due to its specific nature, it's not widely supported outside of GIMP. For sharing, images in XCF format are often exported to more universally recognized formats like PNG or JPEG. |
| Technical details | 🔵 The GIF (Graphics Interchange Format), introduced by CompuServe in 1987, is a bitmap image format with the following characteristics: - Color Limitation: Supports only 256 colors, making it suitable for graphics or logos but not for detailed photographs. - Animation Support: Stores multiple images for animated effects, popular for looping animations and web graphics. - Lossless Compression: Uses LZW compression, reducing file size without quality loss, effective for uniform color images. - Transparency Support: Allows background transparency in images. - Interlacing Option: Offers an interlaced format for quicker loading on slow connections. - Standardization: Original version (87a) in 1987, enhanced version (GIF89a) in 1989 with animation and transparency improvements. - Aspect Ratio: Lacks inherent aspect ratio support. - Applications: Commonly used online for animation and transparency, less so for high-quality photography due to color limits. - No Audio Support: Cannot embed sound. - Metadata: Limited metadata compared to formats like JPEG. - Browser Support: Broadly supported in web browsers and image viewers. - Patent Issues: LZW compression was patented, leading to controversy and PNG development; patent expired in 2003. - File Extensions: .gif or .GIF. Mainly used for web graphics, animations, and simple art, GIF is efficient for images with fewer colors but not ideal for detailed or high-quality images. |
