PNM

PNM (Portable Any Map) is a versatile file format for storing and manipulating images. It supports grayscale, black and white, and color images, making it ideal for various applications in graphics processing. PNM files are easily readable and widely supported by image editing software, offering a simple yet effective way to handle image data without loss of quality.

JSON

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. Widely used in web applications for data exchange, JSON supports a text format that is completely language-independent, making it a preferred choice for APIs and configuration files.
