Background: on a computer screen coordinates are set up as follows:
origin: at the top left corner;
first coordinate axis: horizontal, along the top edge of the screen from left to right;
second coordinate axis: vertical, along the left edge of the screen from top to bottom.
the question: an application window ww on the computer screen has
its top left corner in position (146,46), and
its bottom right corner in position (624,278).
then
ww's top right corner is in position ( , )
ww's bottom left corner is in position ( , )
ww's center is in position ( , )
now, a mouse move shifts the window, and its top left corner arrives in position (436,148)(436,148). then
the translation vector is: ( , )
after the shift,
ww's top right corner is in position ( , )
ww's bottom left corner is in position ( , )
ww's bottom right corner is in position ( , )
ww's center is in position ( , )
