Abstract

A request is sent from a client device to a host device hosting an application capable of providing a split window view of content. Generation of a split window associated with execution of the application on the host device may include at least two split windows. Information regarding the split windows may be sent from the host device to the client device over the communication network. The client device may then use information regarding a first split window to generate an image display corresponding to the first split window. In addition, the client device may process the information regarding a second split window to stitch an image display corresponding to the second split window to the image display corresponding to the first split window. As such, upon scrolling of the display of the client device, the image display corresponding to the second split window may be displayed.

Claims

generates on the single display screen of the host device a split window view of the content file, the split window view comprising at least two split windows in the single display screen of the host device, each split window independently providing a view of a portion of the content file,

scrolls through the content file via a second split window of the at least two split windows in the single display screen of the host device, and

captures a plurality of different images corresponding to the second split window of the at least two split windows as the second split window in the single display screen of the host device scrolls through the content file;

receiving at the intermediary cloud-based device display information over the communication network from the host device, wherein the display information concerns the at least two split window views of the content file;

executing instructions stored in memory, wherein execution of the instructions by a processor;

generates display instructions for the client device, the display instructions concerning an image corresponding to a first split window of the at least two split windows in the single display screen of the host device,

generates stitching instructions for the client device, wherein the stitching instructions concerning stitching of the plurality of different images corresponding to the second split window of the at least two split windows to the image display corresponding to the first split window, and wherein each of the plurality of images is captured during scrolling of the content file in the second split window and each captured image corresponds to a different portion of the scrolled content file; and

sending, via the intermediary cloud-based device, the display instructions and the stitching instructions over the communication network to the client device, wherein the client device displays the image display in the single display screen of the client device corresponding to the first split window and stitches the image corresponding to the first split window and the plurality of images corresponding to the second split window, and wherein the images corresponding to the second split window are not viewable on the single display screen of the client device until a scrolling action is received on the client device.

2. The method of claim 1, further comprising generating the instructions sent to the host device and wherein the host device execution of the instructions sent to the host device causes the application to open the at least two split windows and causes the second split window to scroll through the content file.

3. The method of claim 2, wherein the host device execution of the instructions sent to the host device causes the second split window to scroll automatically to a next portion of the content file when an image of a previous portion of the content file is captured.

4. The method of claim 2, wherein the host device execution of the instructions sent to the host device-causes the plurality of different images to be captured as the second split window scrolls to the different corresponding portions of the content file.

5. The method of claim 1, wherein the stitched images collectively provide an image of the entire content file.

6. An apparatus for using split windows for cross-platform document views, the apparatus comprising:

a communication interface that;

receives a request at an intermediary cloud-based device sent over a communication network from a client device having a single display screen, the request concerning application display information for a content file accessible via an application,

sends instructions, via the intermediary cloud-based device, regarding the request over the communication network to a host device having a single display screen, wherein the host device executes the application to access the content file, and wherein execution of the application;

generates on the single display screen of the host device a split window view of the content file, the split window view comprising at least two split windows in the single display screen of the host device, each split window independently providing a view of a portion of the content file,

scrolls through the content file via a second split window of the at least two split windows in the single display screen of the host device, and

captures a plurality of different images corresponding to the second split window of the at least two split windows as the second split window in the single display screen of the host device scrolls through the content file; and

receives at the intermediary cloud-based device display information over the communication network from the host device, wherein the display information concerns the at least two split window views of the content file;

a processor for executing instructions stored in memory, wherein execution of the instructions by the processor;

generates display instructions for the client device, the display instructions concerning an image corresponding to a first split window of the at least two split windows, and

generates stitching instructions for the client device, wherein the stitching instructions concerning stitching of the plurality of different images corresponding to the second split window of the at least two split windows to the image display corresponding to the first split window, and wherein each of the plurality of images is captured during scrolling of the content file in the second split window and each captured image corresponds to a different portion of the scrolled content file;

wherein the communication interface sends, via the intermediary cloud-based device, the display instructions and the stitching instructions over the communication network to the client device, wherein the client device displays the image display in the single display screen of the client device corresponding to the first split window and stitches the image corresponding to the first split window to the plurality of images corresponding to the second split window, and wherein the images corresponding to the second split window are not viewable on the single display screen of the client device until a scrolling action is received on the client device.

7. The apparatus of claim 6, wherein the processor executes further instructions to generate the instructions sent to the host device and wherein the host device execution of the instructions sent to the host device causes the application to open the at least two split windows and causes the second split window to scroll through the content file.

8. The apparatus of claim 7, wherein the host device execution of the instructions sent to the host device causes the second split window to scroll automatically to a next portion of the content file when an image of a previous portion of the content file is captured.

9. The apparatus of claim 7, wherein the host device execution of the instructions sent to the host device causes the plurality of different images to be captured as the second split window scrolls to the different corresponding portions of the content file.

10. The apparatus of claim 6, wherein the stitched images collectively provide an image of the entire content file.

11. A non-transitory computer-readable storage medium, having embodied thereon a program executable by a processor to perform a method for a cloud-based implementation of using split windows for cross-platform document views, the method comprising:
