Из PNG в JPT

PNG is a raster image format developed by PNG Development Group. The name PNG is an abbreviation for Portable Network Graphic. This image format is used primarily on the Internet for posting on web pages, since PNG files use Deflate compression without losing quality. The development of this format was undertaken in order to replace the GIF format, to which there were many complaints. PNG's image quality and specifications were much better, but unlike GIF, it does not support animation and uses the CMYK palette.

JPT is a file extension belonging to the JPEG 2000 bitmap file category (versions .jp2, .j2k, .jpt and others) and the JPEG 2000 file format. JPEG 2000 format is defined as a system for encoding and transmitting graphic raster files. It was developed by the Joint Photographic Experts Group (JPEG). It is approved by a series of ISO / ITU standards. The JPEG 2000 standard, which was designed from the very beginning to replace traditional JPEG, applies wavelet compression with and without loss. It gives an increased compression ratio and surpasses JPEG by all standards. The standard method for designating JPEG 2000 files is the .jp2 extension. However, other extensions are also used for this. In particular, .jpt. A .jpt file is a JPEG 2000 compressed image. It is saved in the JPT codestream version, where the name means “JPIP Tile-part”. This is a segmented part of JPIP, or the JPEG 2000 interactive protocol. This is the standard JPEG 2000 image streaming protocol. It is oriented to get maximum efficiency and quick access to graphic data. JPT is one of two standard streaming modes. The second mode is called JPP, JPIP Precinct.
