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.
JNG is a raster format. It has a close relationship with PNG. The JNG format uses exactly the same structure as PNG. It stores data in the main JPEG stream, is able to store the alpha channel stream in the form of PNG or JPEG, as well as information in the form of text. It also supports gamma and color correction. This image file format uses lossless compression similar to standard .JPEG files. The format was developed as a sub-format for .MNG objects. However, it is quite suitable as a separate raster image format. Some JNG files include an optional alpha channel for transparency. It does not support standard JPEG files. It is also possible to include auxiliary data sections, which may contain information about color space and comments. JNG is a format that is not very popular. Nevertheless, it has such a very good property as a large degree of lossy graphics compression. He also has an alpha channel. Color data is stored in JPEG format. For alpha, there is one of two storage options. It can be compressed using JPEG, like a grayscale picture. Or you can use the same as in PNG, lossless compression. The format is best suited to store texture atlases in mobile games. A good win for a mobile game.
