Explanation
In the BMP file structure, the Information Header (BITMAPINFOHEADER) stores technical metadata about the image: width, height, color depth (bits per pixel), compression method, image size in bytes, and resolution. The File Header contains the file type signature and file size. The RGBQUAD array defines the color palette for indexed-color images. The Image Data section contains the raw pixel values. Only the Information Header specifies dimensions, compression, and color format.
