png-chunks-encode is a Node.js library that allows developers to construct a new PNG image buffer from a set of PNG chunks, such as IHDR, IDAT, and IEND. It is particularly useful for modifying or adding data to PNG files, including embedding custom chunks like tEXt or zEXt for storing metadata or hidden information. This tool is ideal for developers working on image processing, steganography, or applications that require manipulating PNG file structures.
