Java - as boundaries depend on the window sizes

Question

as boundaries which are selected with red points, from the window sizes depend?

For example, their coordinates with window size 640x480 are (59, 67) and (631, 475).

1. (59, 67) and (696, 545) when 712x579

2. (59, 96) and (809, 682) when 825x687

3. (59, 96) and (990, 748) when 1006x753

how to find regularity of dependence of coordinates from the window size?
