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?
The information header is responsible for specifying the dimensions, compression type, and color format for the bitmap. It contains critical metadata about the image, such as width, height, bits per pixel, and the type of compression used. Other sections like the image data contain the actual pixel data, the RGBQUAD array defines the colors used in indexed color bitmaps, and the header contains the file signature and size.
The other options are not correct: B. Image data: This section contains the actual pixel data of the image. C. The RGBQUAD array: This is a color table that defines the colors used in the image (only present in indexed color bitmaps). D. Header: This is the file header that contains the bitmap file signature and file size, but not the image-specific metadata.
The correct answer is A. Information header. The Information Header (also known as the Bitmap Information Header or BITMAPINFOHEADER) contains essential metadata about the bitmap image, including: Dimensions (width and height) Compression type Color format (bits per pixel) Image size Resolution
A > InfoHeader 0x0E - 0x35 specifies the dimensions, compression type, and color format for the bitmap
