Convert WMZ to PPM

The WMZ file extension stands for Compressed Windows Metafile, a format developed by Microsoft to store vector graphics in a compressed form using Gzip compression. Initially used in older Microsoft Office documents to optimize file sizes for embedded images, WMZ files have become less common with the advent of more modern formats like EMF. These files can be decompressed using utilities like WinZip or 7-Zip, and the resulting WMF files can be viewed or edited in applications such as Microsoft Office and Adobe Illustrator.

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.
