CRW is a highly specialized graphic file format developed by the manufacturer of the famous Canon cameras. It is designed to record “raw” images captured by different models of a digital camera Canon. In its characteristics, it is very similar to another proprietary format of this developer - CR2. The main advantage of the CWR format is the preservation of the quality of the digital image as it comes from the camera matrix. The format also contains metadata, namely: conditions for photographing and fixing the image, default image processing settings, camera model.
PS is one of the common vector image formats. The PS format (full name - PostScript File) was created by Adobe Systems. A vector image that is saved in the PostScript page description language usually contains both text and vector or bitmap graphics. Files of this format can be directly printed without opening an application by a printer that supports PostScript. This dynamic typed programming language is best known for describing pages in the publishing industry. Now the PS format is being actively replaced by the more popular PDF.
