Question: In SMS Picture Messages (as per 3GPP standards), how is the color representation of a pixel determined in a black and white image?
Option 1: Bit value "0" for black, Bit value "1" for white, with an additional byte for grayscale
Option 2: Bit value "0" for white, Bit value "1" for black, with no grayscale support
Option 3: Bit value "0" for transparent, Bit value "1" for colored (using a separate color palette)
Option 4: The most significant bit represents the color (0 for black, 1 for white) in each byte of the pixel row
Explanation: According to the 3GPP standards for SMS picture messages, images are plain black and white with no support for colors or grayscale. Specifically, a bit value of "0" represents a white pixel, and a bit value of "1" represents a black pixel. This binary representation allows for simple, compact storage and transmission of basic images within the constraints of SMS messaging.
