JPM is a JPEG2000 bitmap category file format. The JPEG 2000 Part 6 standard defines that the .jpm extension refers to the JPEG 2000 Composite Image File Format. The JPEG2000 graphic format is a new standard that appeared in 2000 as an update to the JPEG format. He uses a type of technology called wavelet compression, which provides the best ratio of size and quality. The JPM format (i.e., the JPEG 2000 Multi-layer Image Format, ISO 15444-6) was developed for documents that have multiple pages and can be processed as a multi-page photo converter. The purpose of the JPEG 2000 Part 6 composite image format is to work primarily with documents and facsimile images. Compared to regular JPEG 2000 images, a .jpm file is a composite image with many layers. This file can have many pages. Moreover, each such page can have several raster objects. Moreover, in different encodings (JPEG, JPEG 2000, JBIG). They are located in a certain way and make up a single whole. JPM files are used as “digital originals” that store scanned copies of documents and other images and / or texts.
BMP is a graphic format that allows you to store bitmaps as a bitmap based on single-layer rasters. It was developed by Microsoft. She also implemented it in the Windows operating system. The BMP format (English Bitmap Picture) is used in the work of many programs, since its support is integrated into Windows and OS / 2. Files of this format can have the extensions .bmp, .dib or .rle. The BMP graphics format has often changed. From the very beginning, the image structure was built by combining small squares, that is, pixels, each of which is capable of containing data about what color depth is. It happens to be 1, 2, 4, 8, 16, 24, 32, 48 bits per pixel. The size of the final image depends on the bitness. The BMP file format still looks like a monster, since it has large sizes. After all, the image is uncompressed, which can not be said, for example, about the JPG format. Any Windows operating system has the means to open such images. The main editing tool has always been Paint - the native Microsoft program that is in every version of Windows. In BMP, images are stored in their original form, but compression algorithms can also be used. Let's say BMP provides quality support for RLE compression.
