Convert UOT to PPM

The UOT (Uniform Office Document) file extension is used for documents created in the Uniform Office Format (UOF), an open standard developed for Chinese office productivity applications. It uses an XML format to describe the document and is compressed to reduce file size. UOT files can be opened by OpenOffice and its variants. The format is similar to the OASIS OpenDocument format but is not compatible with it.

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.
