Each pixel is 2 bytes (5:6:5 color format).
So 24x1 pixel image takes 48x1 BYTES or if you like 24 words (16 bit) per line
I guess when pixels are not bytes, it makes it more confusing.

: I verified that the image size and the data is correct when calling
GrArea() function (width=height=24, 48x24 bytes of data match image).
I'm still confused here. With width 24, padded to 16 bits will
mean we'd need 32 bits, not 48 as above. Going with
height 1 for simplicity, a 24x1 image would require 4x1=4
bytes to be transferred to the server.
