one question that comes to my mind is if the actual image you are working with 
carries the attribute that color X is transparent... there are many times that i 
work with graphics and block out the entire background in some color that does 
not exist anywhere else in the graphic and then set it as the transparent color 
within the file... on some graphics, this may be a neon green or blue and in 
others it may be white or black... it all depends but the point i'm making is 
what the graphic contains and how those attributes may be being interpreted by 
the code you are using...
