JPS is a bitmap category category format. Its developer is the Joint Photographic Experts Group. A raster stereoscopic JPEG image is stored in a file with a .jps extension. It is this image that is used to create 3D effects from a 2D image. In order to obtain a stereoscopic effect, apply a pair of static images of the same size for the right and left eye. They are nearby. Stored as a single image. Differ from each other, but slightly. They, in particular, have a slightly changed perspective. There are other effects. In other words, this is a pair of copies of the same image. Moreover, each of them is slightly different. Including a different angle. Images with the .jps extension are made and stored using a stereo camera, which should have at least two lenses. Such an image is viewed in several ways. Say, using special devices that provide the opportunity for each eye to see its picture. Hence the effect of volumetric image. In particular, when you overlay pictures on top of each other, then you take 3D glasses. JPS files can also be viewed using programs that can convert a pair of 2D images into one 3D image.
EMF is a vector graphics file for Windows operating system applications. Most image editing applications recognize it. The format was developed in 2007 by Microsoft. This is an integral part of Windows and a version of the original Windows Metafile Format (WMF), extended and expanded. It only supports 16-bit data. Image color data is stored in RGB format. There is no support for CMYK data. EMF (i.e. Enhanced Windows Metafile) can be used as a graphical language for printer drivers. It is used, in particular, to store collections of graphic images of Microsoft Clip Gallery. WMF also found application when it is necessary to transfer information through the clipboard (clipboard). From the Windows operating system, writing and reading to a file of this format can be carried out quickly and without problems. An EMF file is opened using a variety of utilities. For this, for example, IrfanView, CorelDRAW, Inkscape and GIMP are suitable. EMF files, like WMF, have a list of entries. Each of them is a specific team for drawing. Arguments that were 16-bit in WMF became 32-bit in EMF. EMF has features that introduce new arguments.
