Thanks. 

Is there any way to improve the whole process? 

I mean, take a look at the following images:

http://imagebin.ca/view/ymn7xNiw.html
http://imagebin.ca/view/QpXN5P.html
http://imagebin.ca/view/94JeOKm.html

which were created by 

 composite -watermark 20 letterA_shade120x45t.png Christmas2.jpg 
Christmas2-t1.jpg
 composite -watermark 20 -gravity southwest -geometry +20+30 
letterA_shade120x45t.png Christmas2.jpg Christmas2-t2.jpg
 composite -watermark 20 -gravity southwest -geometry +20+30 
letterA_shade120x45t.png lena.jpg lena_sw1.png

All of them need some kind of improvement (to me).

Comparing lena_sw1.png with gimp's result:

one can clearly see the difference.

Or maybe I picked the worst spot? This looks better:

composite -watermark 20 -gravity southwest -geometry +30+20 
letterA_shade120x45t.png lena.jpg lena_sw2.png

But still, I think Christmas2-t?.jpg can use a bit of improvement. 

I've put the original at

Thanks
