Converter JPE to DNG

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.

DNG is an open-source raster image format developed by Adobe Systems and an extension of the TIFF 6.0 cross-platform universal format. The name of the format is an abbreviation of Digital NeGative Specification. The novelty was announced by the developer in 2004 as a standard format for RAW files. It is large in size because it contains not only the main image of high quality, but also metadata, as well as several images for preview (lower quality and resolution). Digital photos in this format are stored in uncompressed form.
