Convert BIB BIBTEX to PPM

BIB, an extension for BibTeX Bibliography Database files, is primarily used in academic writing. BibTeX, short for "Bibliography TeX", assists in managing references within LaTeX documents, offering a streamlined citation process. Developed in the 1980s as part of the TeX typesetting system, BibTeX organizes bibliographic data, supporting various reference styles. These BIB files store citation information such as author names, titles, and publication details, enhancing the efficiency of producing well-organized, consistent bibliographies in technical and scientific documents.

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.
