- Description
 - An ODP file is a presentation created by Impress, a presentation editing application included with Apache OpenOffice. It contains a presentation, which generally includes a title slide followed by content slides with text, images, multimedia content, and transition effects. ODP files are formatted using the OASIS XML-based OpenDocument standard.
 - A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.
