Feature or enhancement

PhotoImage has methodwrite() which writes the image (or its part) to the file. But it lacks methods for two other related subcommand --read, to read the image from the file, anddata, to get the image data. I propose to add methodsread() anddata().

Also, thewrite() method can support two new options:background andgrayscale.
