JPE is the graphic format of the raster image category. It was developed by the standards committee of the Joint Photographic Experts Group. It is a 24-bit compressed graphics format. Typically, it is used for web resources. In most cases, it is used for photographs or images in which there are many colors. Also well suited for many digital cameras to store digital photos. Images that have this extension use lossy compression. And because the quality of individual photos is getting worse. The greater the compression, the less quality the image becomes. The purpose of JPE files is to compress photorealistic images with small color losses. Provides the ability to achieve high compression ratios. We emphasize that usually the maximum compression of graphic information leads to some loss of information. That is, the compression algorithm changes the original data so that the image that is obtained after restoration will be different from the original image, that is, compressed. This compression method is used to work with full-color images that have high photographic quality. During compression, the Discrete-Cosine Transform (DCT), Huffman’s Code quantization and coding are used.
PPT is a presentation format in the popular Power Point application. A file of this format is an editable slide show that consists of a sequence of slides. Directly in the slides can be used not only formatted text, but also video, images, sound and visual effects. The name PPT is an abbreviation for PowerPoint Presentation. The developer of the format is Microsoft. PPT files are created as part of the Microsoft Office PowerPoint software package. Support for the format is possible on Mac OS and Windows, as well as on devices based on Android.
