Please follow the following formulae to find out the region coordinates for any templates or text.

Region = Region(x , y, Width, Height)

Find out the given coordinates from the frame for the particular image region or the text region.

For example consider the following frame.

GNU_manipulation_tools_installation_and_working_update_03

We need to find out the region for the highlighted red filters image .

Launch the gnu app and open the given frame.

Select the required portion in the frame and you will get the x and y coordinates for the particular selected region

We got x = 46 and y = 316

Now we need width and height

GNU_manipulation_tools_installation_and_working_05

Navigate pointer to the right up corner of the image to get width. We will get x1 and y1.

Width = [x 1 - x ] i.e (324-46 = 278)

GNU_manipulation_tools_installation_and_working_06

Navigate pointer to the Left down corner of the image to get width. We will get x1 and y1 again.

Height = [y 1 - y ] i.e (408-316 = 92)

GNU_manipulation_tools_installation_and_working_07

We get region =Region (46 ,316 , 278 ,92)
