Description
The PNM (Portable Any Map Image) file format is a subset of the broader Netpbm format, designed for storing various types of digital images. It acts as an umbrella term for three specific types of grayscale, color, and black-and-white images, represented by PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap) formats respectively. PNM files are known for their simplicity and ease of conversion to other image formats.
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.
