Abstract
Magnified and/or reduced areas of a display are easily determined by the shades of color and a pattern densities which correspond to the magnification or reduction ratio of areas of the display. The areas that have been magnified and/or reduced are presented by varying color intensity within areas reduced in size displayed with a deep hue in color to indicate that the area is compressed and a magnified area is displayed with a lighter color to indicate its expansion. Moreover, images of the display can be presented with a specification corresponding to each magnification or reduction ratio by linking the display with a movement of a pointing device, thus realizing a very easy-to-operate user interface.
Claims12
A method of displaying magnified or reduced areas of a diagram, comprising the steps of:
- storing diagram linkage information as to how other portions of a diagram are affected when a certain portion of a diagram is magnified or reduced;
- magnifying or reducing the certain portion of the diagram with a designated magnification or reduction ratio;
- magnifying/reducing the other portions of the diagram other than the magnified or reduced portion of the diagram in accordance with the diagram linkage information;
- obtaining display specification information characterizing the magnification or reduction ratio of each portion of the diagram;
- and
- displaying each portion of the diagram based on the display specification information characterizing each portion magnification or reduction ratio so that the portions of the diagram are characterized differently depending on their magnification or reduction ratio in the display.
An apparatus for displaying magnified or reduced area, comprising:
- means for storing diagram linkage information as to how other portions of a diagram are affected when a certain portion of a diagram is magnified or reduced;
- means for magnifying or reducing the certain portion of the diagram with a designated magnification or reduction ratio;
- means for magnifying or reducing the other portions of the diagram other than the magnified or reduced portion of the diagram in accordance with the diagram linkage information;
- means for obtaining the display specification information corresponding to the magnification or reduction ratio of each of the portions of the diagrams;
- and
- means for displaying each portion of the diagram based on the display specification information characterizing to each portion magnification or reduction ratio so that the portions of the diagram are characterized differently depending on their magnification or reduction in the display.
A computer program on a computer-readable recording medium for displaying magnified or reduced areas of a diagram, wherein the program comprises:
- software for diagram linkage information indicating how other portions of a diagram are affected when a certain portion of the diagram is magnified or reduced;
- software for magnifying or reducing the certain portion of the diagram with a designated magnification or reduction ratio;
- software for magnifying/reducing the portions of the diagram other than the magnified or reduced portion of the diagram in accordance with the diagram linkage information;
- software for obtaining the display specification information characterizing the magnification or reduction ratio of each of the portions of the diagram;
- and
- displaying each of the portions of the diagram in accordance with the display specification information characterizing each magnification or reduction ratio so that the portions of the diagram are characterized differently depending on their magnification or reduction ratio in the display.
