The PPTX file format is a proprietary XML based file format developed by Microsoft. It is mostly associated with Microsoft office PowerPoint, a closed source slide show presentation application. It is the default format that succeeded the .ppt filename extension from Microsoft PowerPoint 2007 SP1 onwards and is part of the Office Open XML specification. Documents to be saved in the .pptx format are saved as PowerPoint presentations. Because the pptx file format is part of the larger opendocument XML file format, many non-proprietary applications are able to open files saved with the .pptx filename extension.
A .ras extension file is a binary raster image format file that was developed using the UNIX platform by Sun Microsystems. It uses the bitmap format that is simple to use and has the ability to store data in grayscale, black and white as well as colored pixels. The basic layout of a .ras file begins with a header, is followed by a color map and finally by the image data that is bitmapped.

The .pptx filename extension is a compressed ZIP archive with an xml directory structure. The format supports macros, charts, embedded media files, and images. It is specified in the open standard ISO/IEC 29500-1:2012. A free compatibility update allows older versions of Microsoft Office PowerPoint such as Office 2003 to open .pptx documents.
The .ras file extension format extends support to 1, 8, 24 and 32 bits per pixel with easy compression and decompression of the images done with the help of the RLE compression technique which is compatible with other imaging programs. Transparency is not supported in this format. The MIME commands used for this application are image/cmu-master or application/x-cmu-raster.
