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.
J2C is an advanced version of the JPEG format, which is now widely adopted in order to transfer and store digital images. This is a raster image category file. Full name - JPEG 2000 Code Stream. The J2C file format was created by Joint Photographic Experts Group. A format is a lot of advanced features, including efficient coding. The .j2c file extension is a JPEG 2000 image file. This bitmap is created using JPEG 2000 compression. The compression is close to standard .JPG compression. However, it uses a new coding standard, and it is flexible due to computational complexity. Many applications that support standard .JP2 files can view it. A file with the J2C extension opens in the Windows operating system. To view and process a bitmap image in J2C format, you need to use programs such as Corel PaintShop Pro X9, IvanView, ACD Systems Canvas 16, ImageMagick. Using the programs that have been listed, you can convert images, pictures and drawings of the specified format.
