Convert DBK to PPM

The DBK file extension stands for DocBook Technical Document, a semantic markup language used for creating technical documentation in a format-neutral way. Initially developed for computer hardware and software documentation, it allows content to be easily converted into various formats like HTML and PDF. DocBook has become a standard for technical documentation due to its flexibility and open-source nature.

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.
