Question: In a 2-bit greyscale bitmap for SMS, as per 3GPP specifications, how are the color values of pixels encoded in each octet, considering the Most Significant Bits (MSB) represent the leftmost pixel?
Option 1: 00 White, 01 Light Grey, 10 Dark Grey, 11 Black
Option 2: 00 Black, 01 White, 10 Light Grey, 11 Dark Grey
Option 3: 00 Light Grey, 01 Dark Grey, 10 Black, 11 White
Option 4: 00 Black, 01 Dark Grey, 10 Light Grey, 11 White
Explanation: This correct encoding (00 Black, 01 Dark Grey, 10 Light Grey, 11 White) is crucial for accurately rendering user-defined greyscale bitmaps in SMS messages. It ensures that the intended shades of grey are properly displayed on the recipient's device, maintaining the visual integrity of the sent image. Misinterpretation of these bits could lead to incorrect shading, potentially altering the message's aesthetic or even its perceived meaning.
