Thumbnail zoom
File exploration is facilitated by enabling zoom with respect to a thumbnail based on an identified point of interest. More particularly, a scaled thumbnail of the same size as a thumbnail can be generated and presented based on an identified point of interest. In one instance, a scaled thumbnail can be generated automatically by repositioning an image based on a point of interest and applying a scaling factor to the image behind a fixed clipping mask of the same size as the thumbnail. Furthermore, navigation, among other things, is enabled to allow panning with respect to a scaled thumbnail.
1. A method of facilitating file exploration performed by a system comprising at least one processor coupled to a memory storing machine-executable instructions, which, when executed by the processor, control the system to perform acts comprising:
receiving user input specifying a point of interest within a thumbnail caused to be displayed on a display device;
generating a scaled thumbnail automatically by repositioning an image inversely to a location of the point of interest and applying a scaling factor to the image behind a static clipping mask of the same size as the thumbnail; and
causing the thumbnail to be replaced with the scaled thumbnail on the display device.
2. The method of claim 1 , further comprising dynamically generating multiple incrementally scaled thumbnails by incrementally increasing the scale factor as a function of time.
3. The method of claim 2 , further comprising generating each of the multiple incrementally scaled thumbnails at an increasingly slower rate.
4. The method of claim 1 , further comprising:
automatically determining a focal point within the thumbnail based on thumbnail content, wherein the focal point is offset from the center of the thumbnail by a distance greater than zero;
computing an adjusted point of interest using a location of the focal point to shift the point of interest toward the focal point, wherein the point of interest and the focal point are different in location; and
generating the scaled thumbnail based on the adjusted point of interest in place of the point of interest.
5. The method of claim 1 , further comprising accepting a change with respect to underlying content represented by the scaled thumbnail and causing the change to be saved.
6. The method of claim 1 , further comprising initiating loading of a file associated with the scaled thumbnail with a view that matches the scaled thumbnail.
7. The method of claim 1 , further comprising causing the scaled thumbnail to be replaced with the thumbnail on the display device.
8. A system, comprising:
a processor coupled to a memory, the processor configured to execute machine-executable instructions stored in the memory that, when executed, perform the following acts:
receive user input specifying a point of interest within a thumbnail caused to be displayed on a display device;
generate a scaled thumbnail automatically by repositioning an image inversely to a location of the point of interest and applying a scaling factor to the image behind a static clipping mask of the same size as the thumbnail; and
cause the thumbnail to be replaced with the scaled thumbnail on the display device.
9. The system of claim 8 , the acts further comprising dynamically generate multiple incrementally scaled thumbnails by incrementally increasing the scale factor as a function of time.
10. The system of claim 9 , the acts further comprising generate each of the multiple incrementally scaled thumbnails at an increasingly slower rate.

generate the scaled thumbnail based on the adjusted point of interest in place of the point of interest.
12. The system of claim 8 , the acts further comprising accept a change with respect to underlying content represented by the scaled thumbnail and cause the change to be saved.
13. The system of claim 8 , the acts further comprising initiate loading of a file associated with the scaled thumbnail with a view that matches the scaled thumbnail.
14. The system of claim 8 , the acts further comprising replace the thumbnail with the scaled thumbnail upon detecting a pointer over the thumbnail.
