Convert PPT to PPM

PPT stands for "PowerPoint Presentation", a legacy file extension used by Microsoft PowerPoint, which is part of the Microsoft Office suite. Introduced in 1987, PPT files are primarily utilized for creating slide show presentations that include text, images, multimedia, and custom animations. Historically, the PPT format has been instrumental in business, education, and various professional settings for visually engaging presentations. It has since been succeeded by the PPTX format, which offers enhanced performance and security through XML-based structuring.

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.
