In a Tiff file, I want to get the image data in a given rectangle(the Rectangle's location is known: Begining ordinates in the Tiff file and width, height of the range),Then I can put all the data into an Array to process them.

Is there any relative tools or functions available to solve the problem?

Thank you.
