Abstract:
1. A display processing device for displaying a display object in a display window, said device comprising: a section setting unit configured to set a plurality of sections for a display window by dividing said display window into four or more rectangular sections, and setting a linear boundary between adjacent sections, wherein said boundaries form intersections at one or more points where said boundaries intersect; a boundary moving unit configured to accept moving operations for a selected boundary or a selected intersection, and move said selected boundary or said selected intersection, said moving operations defined by dragging said selected boundary or a point corresponding to said selected intersection; a section display range changing unit configured to change a display range for a portion of a display object to be displayed in a section bordering said selected boundary, wherein said display range is changed for each section bordering said selected boundary by an amount corresponding to a change in display size due to said movement of said selected boundary, wherein said display range is increased in a section bordering said selected boundary that has increased in display size due to said movement of said selected boundary, and said display range is decreased in a section bordering said selected boundary that has decreased in display size due to said movement of said selected boundary, and wherein a display range for a portion of an object to be displayed in each section that does not border said selected boundary remains unchanged when said display range is changed for each section that borders said selected boundary; and a section display scale changing unit configured to change a display scale for each section in said plurality of sections that borders said boundaries forming said selected intersection in response to said movement of said point corresponding to said selected intersection, such that said display scale of a section bordering said boundaries forming said selected intersection is changed by an amount corresponding to said change in size of said section bordering said boundaries forming said selected intersection after said point corresponding to said selected intersection is moved.
