- Description
- A PPM file is a 24-bit color image formatted using a text format. It stores each pixel with a number from 0 to 65536, which specifies the color of the pixel. PPM files also store the image height and width, whitespace data, and the maximum color value.
- The JPEG 2000 Code Stream (j2c) file format is a type of image file format that is part of the JPEG 2000 family of image standards. This format is specifically designed for encoding images in a highly efficient manner, allowing for both lossless (exact reproduction) and lossy (approximate) compression. The j2c format focuses on the core coding stream of JPEG 2000 images, representing the encoded image data without additional metadata or structure.
