JPM File – What is .jpm file and how to open it?
JPM File Extension
JPEG 2000 Compound Image – file format by Joint Photographic Experts Group
JPM is a file format developed by JPEG to store and transmit multiple images, metadata, and auxiliary data in a single file. It supports lossless and lossy compression, making it suitable for a wide range of applications from medical imaging to digital cinema.
What is a JPM File?
A JPM (JPEG 2000 Compound Image) file is a compressed image file that contains multiple images, or tiles, within a single file. It uses JPEG 2000 compression, an advanced image compression standard that supports both lossy and lossless compression. JPM files are often used in applications where multiple images need to be stored and accessed efficiently, such as in geospatial imaging, medical imaging, and digital archiving.
Advantages of Using JPM Files
JPM files offer several advantages over other image formats. First, they support lossless compression, meaning the decompressed image is identical to the original image with no loss of quality. Second, JPM files can contain multiple tiles of an image, allowing for efficient access to specific areas of an image without having to decode the entire file. Third, JPM files support metadata, which can provide additional information about the image, such as its creator, creation date, and copyright information.
JPM File Format and Characteristics
JPEG 2000 Compound Image (JPM) files are a specialized format designed to handle complex image compositions, such as multi-resolution, tiled, and layered images. They encompass both the JPEG 2000 (JP2) image coding standard and the JPEG 2000 Part 12 file format, which defines the structure and organization of the compound image data. JPM files facilitate the storage of multiple image representations within a single container, allowing for efficient and versatile image handling.
Opening JPM Files
Accessing and opening JPM files require specialized software that supports the JPEG 2000 Part 12 standard. Several image editors, viewers, and converters are available that provide compatibility with this format. Here are some commonly used options:
- Image Editors: Adobe Photoshop, GIMP, XnView MP
- Image Viewers: Windows Photo Viewer (with codecs), IrfanView
- Image Converters: FileOptimizer, J2K Image Converter
When opening JPM files in these applications, users may encounter options to specify which specific image representation within the compound file to display or extract. The software handles the conversion and decompression of the JPEG 2000 data to present the image in a recognizable format. Additionally, some specialized image analysis and processing tools also support the opening and manipulation of JPM files.
JPEG 2000 Compound Image (JPM) File Format
The JPM file format is a raster image format developed by the Joint Photographic Experts Group (JPEG) as a part of the JPEG 2000 image compression standard. JPM is a compound image format, meaning it can store multiple images and other data within a single file. This makes it a powerful tool for storing complex image data, such as multi-resolution images, geospatial data, and medical images.
JPM files are typically compressed using the JPEG 2000 compression algorithm, which is known for its high compression ratios and lossless image quality. However, JPM files can also be compressed using other lossy or lossless compression algorithms, such as JPEG, PNG, and TIFF. This makes them a versatile format for storing a wide range of image data. Additionally, JPM files support various color spaces, including RGB, grayscale, and CMYK, making them suitable for use in a variety of applications.
