Abstract
Aspects of this disclosure are directed to zooming into or out of image content. A user may request to zoom into or out of image content by inputting a multi-touch gesture. The request may reach one or more discrete zoom levels of a plurality of discrete zoom levels. Discrete zoom levels may indicate specific magnification factors for which a device may be able to clearly render image content. The device may output an indication when the request reaches the one or more discrete zoom levels.
Claims25
A method comprising:
- receiving a multi-touch gesture input comprising a request to zoom in or zoom out of image content that is displayed using a touch-sensitive surface of a device;
- determining, during receipt of the multi-touch gesture input using the touch-sensitive surface, whether the request to zoom in or zoom out of the image content has reached one or more discrete zoom levels of a plurality of discrete zoom levels, wherein the one or more discrete zoom levels are between a maximum and a minimum zoom boundary for displaying the image content, and wherein each one of the one or more discrete zoom levels comprises a magnification factor for a stored version of the image content that is zoomed in or zoomed out to that magnification factor;
- and
- outputting, by the device, an indication to alert a user when the request reaches the one or more discrete zoom levels.

A computer-readable storage medium comprising instructions that cause one or more processors to:
- receive a multi-touch gesture input comprising a request to zoom in or zoom out of image content that is displayed using a touch-sensitive surface of a device;
- determine, during receipt of the multi-touch gesture input using the touch-sensitive surface, whether the request to zoom in or zoom out of the image content has reached one or more discrete zoom levels of a plurality of discrete zoom levels, wherein the one or more discrete zoom levels are between a maximum and a minimum zoom boundary for displaying the image content, and wherein each one of the one or more discrete zoom levels comprises a magnification factor for a stored version of the image content that is zoomed in or zoomed out to that magnification factor;
- and
- output, by the device, an indication to alert a user when the request reaches the one or more discrete zoom levels.

A device comprising:
- a touch-sensitive surface that receives a multi-touch gesture input comprising a request to zoom in or zoom out of image content that is displayed using a touch-sensitive surface of the device;
- means for determining, during receipt of the multi-touch gesture input using the touch-sensitive surface, whether the request to zoom in or zoom out of the image content has reached one or more discrete zoom levels of a plurality of discrete zoom levels, wherein the one or more discrete zoom levels are between a maximum and a minimum zoom boundary for displaying the image content, and wherein each one of the one or more discrete zoom levels comprises a magnification factor for a stored version of the image content that is zoomed in or zoomed out to that magnification factor;
- and
- one or more processors that output an indication to alert a user when the request reaches the one or more discrete zoom levels.
