Abstract

Dynamically-generated images sized according to a requesting web client application display resolution are provided. The client application may calculate a target display resolution and pass the target display resolution as an input parameter with a request to a server for application content. The server may use the desired size input parameter to determine an optimal image size for the target display resolution. The server may render the application content as one or more images to the optimal image size and send the rendered image(s) to the client application. A determination may be made by the client application to display the image(s) at the size received or to scale the server-provided image(s). If the available area in the client application pane changes, the client application may recalculate the target display resolution and issue a new request to the server with the new target display resolution as the desired size input parameter.

Claims

1. A method for providing a dynamically generated image sized according to a target display resolution, the method comprising:

calculating an input parameter relating to the target display resolution, the input parameter including a size of an available area for displaying application content;

sending a request for application content, the request comprising the input parameter relating to the target display resolution for the application content;

receiving the application content as one or more images rendered according to the target display resolution, the one of more images having a selected size for the available area;

determining whether to display the one or more images at the selected size or to scale the one or more images to reduce empty space around the application content;

when it is determined to scale the one or more images, scaling the one or more images to a larger size to reduce the empty space around the application content while maintaining image fidelity in accordance with the target resolution; and

displaying the one or more images.

2. The method of claim 1, wherein the target display resolution is in a browser application pane for displaying the application content, the available area including area not occupied by user interface elements.

3. The method of claim 1, wherein sending a request for application content comprises sending a request of application content to a server.

4. The method of claim 1, wherein receiving the application content as one or more images comprises receiving the application content as one or more bitmap images.

5. The method of claim 1, wherein receiving the application content as one or more images rendered according to the target display resolution includes receiving one or more images having the selected size to minimize empty space around the application content displayed at the selected size.

6. The method of claim 1, wherein receiving the application content as one or more images rendered according to the target display resolution includes receiving one or more images sized to one of a number of predetermined image sizes.

7. The method of claim 1, wherein determining whether to scale the one or more images includes determining a threshold for scaling the one or more images, wherein the threshold is based on a ratio of a size of the one or more images compared to the available area.

8. The method of claim 7, wherein the threshold for scaling the one or more images is having the available area be ten percent larger than the one or more images.

9. The method of claim 7, wherein the threshold for scaling the one or more images is having the available area be greater than five percent larger than the one or more images.

10. The method of claim 1, further comprising:

receiving an indication of a change of the available area for displaying application content;

calculating a new input parameter relating to a new target display resolution, the new input parameter including a new size for the available area for displaying the application content;

sending a request for application content, the request comprising the input parameter relating to the new target display resolution;

receiving the application content as one or more images rendered according to the new target display resolution, the one or more images having a new selected size; and

displaying the one or more images at the new selected size.

11. The method of claim 10, wherein prior to receiving the application content as one or more images rendered according to the new target display resolution, scaling the one or more images currently displayed to fit the new size for the available area.

12. A system for providing a dynamically generated image sized according to a target display resolution, the system comprising:

a communication media configured to communicate with a server;

a memory; and

a processor configured to;

calculate an input parameter relating to the target display resolution, the input parameter including a size of an available area for displaying application content;

send a request for application content, the request comprising the input parameter relating to the target display resolution for the application content;

receive the application content as one or more images rendered according to the target display resolution, the one or more images having a selected size for the available area;

determine whether to display the one or more images at the selected size or to scale the one or more images to reduce empty space around the application content;

when it is determined to scale the one or more images, scale the one or more images to a larger size to reduce empty space around the application content while maintaining image fidelity in accordance with the target resolution; and

display the one or more images.

13. The system of claim 12, wherein the target display resolution is an available area in an application pane for displaying application content, the available area including area not occupied by user interface elements.

14. The system of claim 12, wherein the one or more images are one or more bitmap images.

15. The system of claim 12, the selected size is a size that minimizes empty space around the application content displayed at the selected size.

16. The system of claim 12, wherein the one or more images rendered according to the target display resolution are sized to one of a number of predetermined image sizes.

17. The system of claim 12, wherein the processor if further configured to:

receive an indication of a change of the available area for displaying application content;

calculate a new input parameter relating to a new target display resolution, the new input parameter including a new size for the available area for displaying the application content;

send a request for application content, the request comprising the new input parameter relating to the new target display resolution

receive the application content as one or more images rendered according to the new target display resolution, the one or more images having a new selected size; and

display the one or more images at the new selected size.

18. The system of claim 17, wherein the processor is further configured to scale the one or more images currently displayed to fit the new size for the available area prior to receiving the application content as one or more images rendered according to the new target display resolution.

19. A computer storage medium having computer-executable instructions for providing a dynamically generated image sized according to a target display resolution, the method comprising:

calculating an input parameter relating to the target display resolution, the input parameter including a size of an available area for displaying application content, wherein the target display resolution is in a browser application pane for displaying the application content, the available area including area not occupied by user interface elements;

sending a request for application content to a server, the request comprising the input parameter relating to the target display resolution for the application content;

receiving the application content as one or more images rendered according to the target display resolution, the one or more images having a selected size for the available area, wherein the selected size is calculated to minimize empty space around the application content when the application content is displayed at the selected size;

determining whether to display the one or more images at the selected size or to scale the one or more images to show less of the available area as empty space;

when it is determined to scale the one or more images, scaling the one or more images to a larger size to show less of the available area as empty space while maintaining image fidelity in accordance with the target resolution; and

displaying the one or more images.

20. The computer storage medium of claim 19, further comprising:

receiving an indication of a change of the available area for displaying application content;
