| 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 | 🔵 The PPM format is a versatile way to store portable pixmap images. It's simple, yet effective in capturing color (PPM), grayscale (PGM), and black and white (PBM) images. It's a convenient tool for transferring bitmap image files of these three types across different platforms. The credit for creating the PPM format goes to Jeff Poskanzer. |
| Technical details | 🔵 A PPM file is made up of one or more PPM images lined up in sequence. There is no additional data, padding, or constraints before, during, or after the images. Each PPM image has a unique identifier known as a magic number, specifically "P6". This is followed by whitespace characters (spaces, TABs, CRs, and LFs) and the image width, expressed as ASCII characters in decimal form. Another ASCII decimal space follows this. The color value, or Maxval, within a PPM image is given in decimal form. It should be more than zero but less than 65536. A single whitespace character on a separate line follows the Maxval. The image is then made up of a raster of height rows, arranged in reverse order. Each row comprises width pixels, laid out from left to right. The samples in a PPM image consist of binary information, represented by one or two bytes. If the Maxval is less than 256, the sample is one byte. If it's more, it's two bytes with the first byte being the most significant. There is also an alternate version of the PPM format known as the straightforward format, but it's not commonly used. |
