- Description
- The bw file type is associated with Silicon Graphics RGB, a bitmap image format developed by Silicon Graphics, Inc. (SGI). It is specifically designed for grayscale images, utilizing a single channel to represent varying shades of black and white. The format is known for its use in graphics and visualization applications, especially in environments where Silicon Graphics workstations were prevalent. BW files are capable of storing high-quality images with efficient compression, making them suitable for both professional graphics work and scientific visualization.
- 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.
