Convert BIB BIBLATEX to PPM

A BIB file (short for Bibliography) is a plain text document used in conjunction with the LaTeX typesetting system to manage and format bibliographic references. Created by Oren Patashnik and Leslie Lamport in 1985, BIB files store references in BibTeX format, allowing for consistent citation and bibliography generation across documents. This format is widely supported by reference management software and is particularly useful for academic and research publications.

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.
