What is a .BW file?
The .BW file extension is used for a type of image file known as a Black and White SGI Image File. This format was developed by Silicon Graphics and is primarily used for storing images that are only in black and white. These files are a native format used on Silicon Graphics workstations, which are specialized computers used mainly for graphics processing and scientific applications.
The .BW files can be either uncompressed, which means the image data is stored without any loss of information, or they can be compressed using run-length encoding (RLE). RLE is a form of data compression where sequences of the same data value are stored as a single data value and count, rather than as the original run. This is particularly efficient for the kinds of simple, repetitive data patterns often found in black and white images.
To view or manipulate .BW files, you can use several software programs: 1. **FFmpeg** - This is a free and open-source software project consisting of a vast software suite of libraries and programs for handling video, audio, and other multimedia files and streams. FFmpeg can be used to convert .BW files into other formats.
2. **ImageMagick** - This is a free software suite for creating, editing, composing, or converting bitmap images. It can read and write images in a variety of formats, including .BW files.
3. **File Viewer Plus** - This is a paid application available from the Microsoft Store that supports viewing, editing, and converting various file formats, including .BW files.
More Information: - If the SGI image contains RGB (red, green, blue) color data, it uses the .RGB file extension. - If the RGB image also includes an alpha channel, which is used for transparency, the file extension is .RGBA. These different extensions help users and software distinguish between different types of image data and handle them appropriately.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files.
