| Description | 🔵 Portable Network Graphics, or .png, is a raster graphics file format. Simply put, it's a digital image format. PNG files are popular online because they use lossless data compression and support transparent backgrounds. |
| Technical details | 🔵 Let's look at the technical details of the .png format: PNG compression is lossless, meaning that all the image data is kept during compression. This is different from JPEG, which uses lossy compression and loses some image information to make smaller files. PNG images can range from basic black-and-white (1-bit) to very detailed images with 48 bits of color. They also support 16-bit grayscale images. A key feature of PNG is its support for alpha channel transparency. This lets you create images with varying degrees of transparency, from completely opaque to completely transparent. This is very useful for web graphics. PNG supports a full range of colors (truecolor), allowing for up to 16 million colors. It also supports indexed-color images, which use a palette of up to 256 colors. In short, PNG files are widely used because of their efficient compression, support for many different color palettes, and the ability to handle various transparency levels. These features make them perfect for many web applications. |

| Description | 🔵 Computer Graphics Metafile is explicitly used as a format for storing and sharing positional graphics while retaining the details and quality of the image irrespective of the technological platform or device on which it is utilized. The CGM format has been in use as far back as 1986 when it was first released. Unlike some image formats that handle two-dimensional positional image, or bitmap image alone, CGM supports both. Image files are saved as CGM when highly fine details are essential. Such applications include structure design images in aviation, engineering, and other similar technical fields. |
| Technical details | 🔵 With most graphics applications used for computer-aided design and detailed simulation of engineering designs, CGM is the most prolific file format for archiving such works. CGM is a metafile file format that permits representing all graphical elements of an image in a plain-text, binary, or character-based source document. Each of the mentioned CGM source data representation comes with its merit. Binary coded CGM files are accessible for programs to decode and analyze. Character-based CGM files produce the smallest file size, relative to the other encoding methods, forthwith becomes the fastest to transfer. Plain-text CGM files have the advantage of being editable with any text editor. |
