Convert PPTM to PNM

PPTM stands for PowerPoint Macro-Enabled Presentation, a file extension used by Microsoft PowerPoint for presentations that include macros. These files enhance functionality by allowing automation of repetitive tasks through embedded scripts written in VBA (Visual Basic for Applications). Introduced with Microsoft Office 2007, the PPTM format evolved from the PPTX format, incorporating macro capabilities while maintaining the XML-based structure. Its primary use is in environments requiring advanced automation and customization features, making it indispensable for professionals seeking efficient workflow management in presentations.

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.
