JP2 is a bitmap image format. The JP2 format, i.e. JPEG 2000 image, was developed by the Joint Photographic Experts Group. The JP2 file can be in the form of a photograph, drawing, digital fax, etc. File type: JPEG 2000 Core Image File. JPEG 2000 is the patent-pending bitmap image format. It has been licensed free of charge, and now it is an international standard (ISO / IEC 15444-1: 2004). Compared to the previous JPEG-1 standard, JPEG 2000 uses a completely different method to compress data (wavelet transform, wavelet transform). This method generally ensures higher image quality. It also gives a more compact file size. The JP2 format has a lot in common with the JPEG format, which is now especially popular. However, it differs in that it uses wavelet transform technology for compression, and discrete cosine transform has found application in JPEG. Using the first technology, you can get a better image, even when the file size is relatively smaller. There are also JP2 files with the extensions .J2K, JPF, MJ2, JPX and JPM. In order to open a file of this format, that is, to edit, use programs such as Mozilla Firefox, Adobe Photoshop, ACD Systems ACDSee, Google Chrome.
PPM is an image file format that is included in the Netpbm open source graphics editor. This graphic format is convenient and simple. Other Netpbm formats that have found widespread use are PBM, i.e. Portable Bitmap, as well as PGM, i.e. Portable Graymap. This three graphic formats are sometimes referred to as PNM, i.e. Portable Format Anymap. PGM stores grayscale images. PMP is a collection of color images, which are intermediate files that are used when converting formats not so well known, using Portable Bitmap Utilities. And PPM files are mainly used on UNIX platforms that are based on Intel. These files are categorized as bitmap images. This is a 24-bit color image that has been formatted in text format. Takes every pixel with a number from zero to 65536 for storage. The color of the pixel is determined by the number. Contains data spaces, the height and width of the character, the maximum color values. Portable Pixmap uses an uncompressed low-performance format that can be compared with other bitmap image formats. This explains its rare use in order to store large images.
