pnm
| Extension | .pnm |
| Category | 🔵 images |
| 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. |
sun

| Description | 🔵 .sun The .sun file format is associated with Sun raster files, which are a raster graphics file format originally used on SunOS by Sun Microsystems. It's a bitmapped format, which means it contains a bitmap of the image. However, this format is not commonly used anymore and has been largely replaced by more modern and efficient image formats like PNG and JPEG. |
| Technical details | 🔵 The `.sun` file extension, associated with the Sun Raster image format developed by Sun Microsystems, is not as widely recognized as standard formats like .jpg or .png. This raster image format, used mainly on Sun's Unix-based systems, is designed for pixel-based images, supporting various color depths like 1-bit (black and white), 8-bit (gray-scale or indexed color), and 24-bit (true color). It offers simple RLE (Run-Length Encoding) compression but can also store uncompressed image data. The file structure includes a header detailing image dimensions and bit depth, followed by the image data. Its use was mainly within Sun Microsystems environments, leading to limited adoption and support in modern software. Now considered a legacy format, Sun Raster files often require conversion to more common formats for use today. The format is of historical interest, reflecting its specific role in Sun Microsystems' ecosystem rather than as a widely accepted standard. |
