Detail-in-context lenses for digital image cropping, measurement and online maps
View Patent ↗In one or more implementations, a signal is received selecting a geographic location in an original image of a digital map for display on a display. The original image is distorted to give an appearance of a lens being applied to the digital map for display on the display, the appearance of the lens including a focal region that includes a magnification of the geographic location and a base region that surrounds the focal region.
1. A tangible computer-readable media device comprising instructions stored thereon that, in response to execution by a system, causes the system to perform operations comprising:
defining a line segment between geographic locations on an image of a digital map; and
distorting the image to give an appearance of a lens in response to the defining of at least one end of the line segment, the appearance of the lens including:
a focal region having a magnification of at least a portion of the line segment; and
a base region that surrounds the focal region and that includes a magnification that provides a continuous transition from the magnification of the focal region to the image.
2. The tangible computer-readable media device of claim 1 , wherein at least one of the geographic locations is a street.
3. The tangible computer-readable media device of claim 1 , wherein the distorting causes a street name to be revealed.
4. The tangible computer-readable media device of claim 1 , wherein the focal region has a size and a shape and further comprising receiving one or more signals for adjusting at least one of the size, the shape, or a magnification of the focal region.
5. The tangible computer-readable media device of claim 1 , wherein one or more signals are received through a GUI to define the line segment.
6. The tangible computer-readable media device of claim 1 , wherein the instructions, in response to execution by the system, are configured to provide a graphical user interface (GUI) to adjust at least one of a size, a shape, or a magnification of the appearance of the lens.
7. The tangible computer-readable media device of claim 6 , wherein the GUI includes at least one of:
a slide bar icon for adjusting a magnification for the appearance of the lens;
a slide bar icon for adjusting a degree of scooping for the appearance of the lens;
a bounding rectangle icon with at least one handle icon for adjusting a size or a shape for the focal region;
a bounding rectangle icon with at least one handle icon for adjusting a size or a shape for the base region;
a move icon for adjusting a location for the appearance of the lens on the line segment;
a pickup icon for adjusting a location for the base region within the original image; or
a fold icon for adjusting a location for the focal region relative to the base region.
8. The tangible computer-readable media device of claim 1 , wherein the line segment is a straight line.
