Description	🔵 .png (Portable Network Graphics) The .png format is a raster graphics file format that supports lossless data compression. PNG files are widely used on the internet due to their efficient compression and support for transparent backgrounds.
Technical details	🔵 Here are some technical details about the .png format: - Lossless Compression: PNG uses lossless compression, preserving all image data during compression. This is unlike formats like JPEG, which are lossy and discard some information for smaller file sizes. - Bit Depth: PNG images can range from 1-bit (black and white) to 48-bit color, and also supports 16-bit grayscale images. - Transparency Support: A key feature of PNG is its support for alpha channel transparency, allowing for varying levels of transparency in the image, from fully opaque to fully transparent. This is particularly useful for web graphics. - Color Palettes: PNG supports truecolor (16 million colors) as well as indexed-color images with a palette of up to 256 colors.

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.
