You would need to draw the data onto the image if you want it to
appear.  I would suggest using our function DrawTextStr to draw
the text on to the image.  However there is a trick to drawing
text on a 16 bpp image.  Windows does not support creating a
device context for a 16 bit per pixel image.  So you have to draw
on an 8 bpp grayscale image, convert that image to 16 bpp, create a
region based on the font color, then combine the region onto the 16 bpp image you want the text to appear. 

I have provided an example showing how to do this in Delphi.
