Portable Gray Map Image
| Extension | .pgm |

| Programs | 🔵 ACD Systems ACDSee 18 🔵 ACD System Canvas 15 🔵 Adobe Photoshop with plug-in 🔵 Corel PaintShop Pro X8 🔵 GIMP 🔵 Inkscape 🔵 Netpbm |
| Description | 🔵 The PGM file format was developed in conjunction with the open-source Netpbm graphics program package. Created by Jef Poskanzer in 1988, PGM was designed to store grayscale images and support bitmap images. This file format is compatible with modern graphics editing software such as Corel PaintShop Pro X4, ACDSee Photo Manager 14, and ACD Systems Canvas 15. Since PGM is a plain text format, it can be easily edited using any text editor, making it resistant to changes that can occur when images are transmitted via email. PGM files are classified into two types, distinguished by magic numbers - P2 and P5, which assist graphics editing software in identifying the data encryption standard. |
| Technical details | 🔵 Portable Gray Map Images can be stored with each pixel consuming either 8 or 16 bits of memory space. A PGM file consists of two main sections - the header and the image data. The header begins with a magic number, followed by characters indicating the image width, image height, and maximum grayscale shade value, which should not exceed 65,536. These data are separated by whitespaces. While primarily used on UNIX-based operating systems, the open-source nature of PGM files allows for compatibility with macOS and Windows. |

hrz
| Extension | .hrz |
| Category | 🔵 images |
| Description | 🔵 The HRZ file format is a binary format used for storing astronomical images. It was developed by the European Southern Observatory (ESO) and is commonly used in the field of astronomy. |
| Technical details | 🔵 HRZ files store two-dimensional images in a compressed format, typically containing a single color channel. The format supports 8-bit and 16-bit integer data, as well as 32-bit and 64-bit floating-point data. The file format is designed to be platform-independent, and supports both big-endian and little-endian byte ordering. HRZ files can contain header information that describes the image size, data type, and other relevant parameters. The HRZ format is used by a variety of astronomical software packages, including IRAF, MIDAS, and SExtractor. It is also supported by some image processing and analysis software tools, such as ImageJ and MATLAB. |
