- Description
- A JP2 file is a compressed bitmap image created using JPEG 2000 Core Coding. It incorporates a wavelet compression algorithm instead of Digital Cosine Transform (DCT) compression, which is used by standard JPEG images. JP2 files can be stored using lossy and lossless compression.
- Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
