Convert UOP to PPM

The UOP file extension stands for Uniform Office Presentation, an open document format developed for Chinese office productivity applications. It uses XML to describe presentations and stores them as compressed archives, similar to the OpenDocument format. UOP files are primarily used with OpenOffice Impress for creating and viewing presentations. Historically, the format was created to support Chinese language office applications and has been adopted by various office suites.

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.
