Convert DIB to PPM

A Device Independent Bitmap (DIB) is a format for storing bitmap graphics, ensuring compatibility across different devices and platforms. Its primary use is to enable consistent image representation, regardless of the display hardware or software. Originating from early Windows operating systems, DIBs allowed developers to create graphics that would render accurately on various hardware. Today, DIBs are integral in applications needing uniform image display and manipulation, maintaining their relevance in diverse technological contexts.

The Portable Pixmap (PPM) file extension, an image format within the Netpbm family, stores simple, uncompressed images. Introduced in the late 1980s, PPM supports RGB color and grayscale images, making it suitable for basic image processing and conversion tasks. Its plain text encoding simplifies debugging and data manipulation, although its lack of compression results in larger file sizes compared to modern formats. As such, PPM finds limited use in contemporary applications, mainly in educational and experimental settings where ease of implementation and readability are prioritized.
