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.
PBM is a raster image category file format. It is a compact single-bit black and white image. In other words, this is a simple format that allows you to store black and white pictures. It can be easily formatted into text. In this raster image format, if the pixel is a byte of one, it represents black pixels. When it is a byte from zero, it represents white pixels. The format is referred to as the Portable Bitmap Image file type. How can I open this format? To do this, use programs such as Adobe Photoshop CS, some versions of ACD Systems, as well as Newera Graphics Converter Pro, Corel PaintShop Pro X6. The file has 1 bit per pixel. PBM is a type of PPM format. PBM, that is, Portable Bitmap, is part of the Netpbm graphics package along with a couple of other formats: PGM, that is, Portable Graymap; PPM, i.e. Portable Pixelmap. Occasionally, these three formats are combined under the general name PNM (Portable Anymap). These are intermediate files used in conversion processes supported by Portable Bitmap Utilities (these are applications that have open source code). The PBM format is linked in black and white bitmap images. In PGM, grayscale bitmaps. PPM stores color bitmaps.
