| Description | 🔵 The Portable Any Map (PNM) format is a collection of image file formats designed for portable images. Each image essentially represents a pixel value map that can encode data in grayscale or color. There are three main types of files in the PNM format family: Portable BitMap (PBM), Portable GrayMap (PGM), and Portable PixMap (PPM). |
| Technical details | 🔵 PBM format uses binary pixel data. Each pixel is represented by a single bit, where 0 indicates black and 1 represents white. The pixel data for each row is organized as a bit sequence, padded to a full byte. Conversely, the PGM format handles grayscale pixel data. It represents each pixel with a single byte. The pixel data is arranged in rows, with each row of pixel data grouped together. PPM format deals with color pixel data. Each pixel is represented by three bytes, each indicating the red, green, and blue components of a color. This pixel data is also organized in rows, with each row grouped together and represented by sets of three bytes. Finally, note that PNM files can be easily converted between these three formats. Furthermore, specific software tools can convert PNM files to other image file formats, and vice versa. |

| 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. |
