Transfer LCD image to SD bmp

I use a 3.2" SainSmart TFT LCD Display with SD card and an Arduino Mega 2560 R3 with a Mega2560 Shield. I use the Henning Karlsen UTFT library and examples that are found on UTFT - Rinky-Dink Electronics.
I want to save a still image as it appears on the LCD to a file on an SD card. How can that be done? Are there examples to do that?
Kindest Regards,
MJM

How did that image get there?
