Question

BMP (Bitmap) is a standard file format for computers running the Windows operating system. BMP images can range from black and white (1 bit per pixel) up to 24 bit color (16.7 million colors). Each bitmap file contains a header, the RGBQUAD array, information header, and image data. Which of the following element specifies the dimensions, compression type, and color format for the bitmap?

Options

  • AInformation header
  • BImage data
  • CThe RGBQUAD array
  • DHeader

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.
