Method for automatically adjusting the magnification and offset of a display to view a selected feature
View Patent ↗A method for operating a display in a data processing system to provide a view of a portion of a data array on a display screen is disclosed. The method includes providing a first display window characterized by a first offset, a first horizontal gain, and a first vertical gain and receiving a feature input from a user indicating a selected feature in the first display window. The data processing system automatically provides a second display window characterized by a second offset and a second horizontal gain and a second vertical gain. The second offset, the second horizontal gain and the second vertical gain are chosen such that the feature is at a predetermined location in the second display window and the second horizontal gain and second vertical gain are chosen such that the selected feature occupies a predetermined portion of the second display window.
1. A method for operating a display in a data processing system to provide a view of a portion of a data array on a display screen, said method comprising:
providing a first display window characterized by a first offset, a first horizontal gain, and a first vertical gain;
receiving a feature input from a user indicating a selected feature in said first display window; and
automatically providing a second display window characterized by a second offset and a second horizontal gain and a second vertical gain, wherein said second offset, said second horizontal gain and said second vertical gain are chosen such that said selected feature is at a predetermined location in said second display window and said second horizontal gain and second vertical gain are automatically chosen by said data processing system such that said selected feature occupies a predetermined portion of said second display window, said second horizontal gain being greater than said first horizontal gain, said predetermined portion of said second display window depending on said selected feature,
wherein said feature input from said user comprises an indication of a feature type for said selected feature and wherein said second horizontal gain depends on said feature type, said feature type being chosen from a plurality of predetermined feature types.
2. A method for operating a display in a data processing system to provide a view of a portion of a data array on a display screen, said method comprising:
providing a first display window characterized by a first offset, a first horizontal gain, and a first vertical gain;
receiving a feature input from a user indicating a selected feature in said first display window; and
automatically providing a second display window characterized by a second offset and a second horizontal gain and a second vertical gain, wherein said second offset, said second horizontal gain and said second vertical gain are chosen such that said selected feature is at a predetermined location in said second display window and said second horizontal gain and second vertical gain are automatically chosen by said data processing system such that said selected feature occupies a predetermined portion of said second display window, said second horizontal gain being greater than said first horizontal gain, said predetermined portion of said second display window depending on said selected feature,
wherein said input from said user comprises an indication of a feature type for said selected feature and wherein said second vertical gain depends on said feature type, said feature type being chosen from a plurality of predetermined feature types.
