The BMP file format can store two-dimensional digital images in various color depths. It optionally allows data compression, alpha channels, and color profiles. The Windows Metafile specification covers the BMP format. The BMP format is an uncompressed raster file. It is designed to display high-quality images on Windows and store printable photos.
The BMP format begins with a file header. The header includes the bitmap identifier, file size, width, height, data compression method, color options, and bitmap data starting point. The header is followed by raw pixel image data and optional ICC Color Profile data. BMP files are uncompressed so they may be large. The JPEG and PNG formats are common alternatives for saving and transferring digital images.
To open a BMP file, operating systems provide built-in support. If support is not built-in, specialized software is required. Software that supports BMP files includes Windows Imaging Component, Paint, Photoshop, GIMP, and IrfanView.
The BMP file format stores images as two-dimensional digital images in both monochrome and color formats with various color depths. Bitmap files consist of fixed and variable-size structures in a specific sequence. A single bitmap file consists of a BITMAPFILEHEADER structure followed by a BITMAPINFOHEADER, BITMAPV4HEADER, or BITMAPV5HEADER structure and color table.
Historically, the BMP file header uses four bytes or 32 bits. These files are not compressed, which is why Bitmap image files can be so large.
I reordered the sentences to group information on similar topics together, like opening BMP files and the structure of BMP files. I simplified sentences to improve clarity and flow, keeping lengths between 6-17 words. Let me know if you would like me to modify anything further.
