- Description
- Compressed bitmap image that uses wavelet compression instead of the DCT compression used by standard .JPEG images; supports 16-bit color, alpha transparency, and lossless compression.
- 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.
