Abstract
A device is capable of displaying an image. The device includes a memory having a first memory portion for receiving a set of image data. A display has a viewport for displaying the set of image data in an image that fits within and fills the viewport. A processor is programmed for executing computer program instructions for receiving a zoom factor selected by a user; applying a zoom transformation to a first subset of the image data corresponding to points in a first region of the image that are displayed within the viewport after magnifying the first region based on the zoom factor; and displaying the zoom transformed first subset of the image data so as to fill the viewport, while a second subset of the image data representing points outside the first region have not been transformed.
Claims25
A method for displaying an image, comprising:
- receiving a set of image data for displaying an image that fits within and fills a viewport of a device;
- receiving a zoom factor selected by a user;
- applying a zoom transformation to a first subset of the image data corresponding to points in a first region of the image that are displayed within the viewport of the device after magnifying the first region based on the zoom factor,
- displaying the zoom transformed first subset of the image data so as to fill the viewport, while a second subset of the image data representing points outside the first region have not been transformed.
A device capable of displaying an image, comprising:
- a memory having a first memory portion for receiving a set of image data a display having a viewport for displaying the set of image data in an image that fits within and fills the viewport;
- and
- a processor programmed for executing computer program instructions for:
- receiving a zoom factor selected by a user;
- applying a zoom transformation to a first subset of the image data corresponding to points in a first region of the image that are displayed within the viewport after magnifying the first region based on the zoom factor,
- displaying the zoom transformed first subset of the image data so as to fill the viewport, while a second subset of the image data representing points outside the first region have not been transformed.
A computer readable storage medium encoded with computer program code, such that, when the computer program code is executed by a processor, the processor performs a method for displaying an image, comprising:
- receiving a set of image data for displaying an image that fits within and fills a viewport of a device;
- receiving a zoom factor selected by a user;
- applying a zoom transformation to a first subset of the image data corresponding to points in a first region of the image that are displayed within the viewport of the device after magnifying the first region based on the zoom factor,
- displaying the zoom transformed first subset of the image data so as to fill the viewport, while a second subset of the image data representing points outside the first region have not been transformed.
