Convert PPT to PNM

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 PNM (Portable Anymap) file extension, developed by Jef Poskanzer in the 1980s, stands for Portable Any Map. It is an uncompressed raster graphics format designed for portable image storage and exchange, encompassing three sub-formats: PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap). PNM files store image data in plain text or binary format, ensuring easy usage across different platforms and applications. This format is widely supported by various image editing software and is valued for its simplicity and lossless compression.
