Abstract

In particular embodiments, a method includes receiving from an application a first graphics device interface (GDI) call and adding the first GDI call to a list of events. The method further includes receiving from the application one or more second GDI calls, wherein each of the second GDI calls is related to the first GDI call and adding the second GDI calls to the list of events. The method further includes receiving from the application a third GDI call, wherein the third GDI call is not related to the first GDI call, and performing a call to a GDI system, the call including the list of events.

Claims

1. A method comprising, by a computing device:

intercepting, by an intermediate function, from an application a first graphics device interface (GDI) call after a painting function and before a rendering function;

adding the first GDI call to a list of events, wherein each event comprises regionally related graphics data for re-creation;

intercepting, by the intermediate function, from the application one or more second GDI calls, wherein each of the second GDI calls is related at least as to a region to the first GDI call;

adding the second GDI calls to the list of events;

intercepting, by the intermediate function, from the application a third GDI call, wherein the third GDI call is not related to the first GDI call, wherein intercepting the first GDI call, the one or more second GDI calls and the third GDI call prevents the application from directly accessing a GDI system;

performing a call to the GDI system once the region is fully defined, the call comprising the list of events, wherein the call to the GDI system comprises a single system GDI event; and

render to a display data associated with at least one event of the list of events.

2. The method of claim 1, wherein:

the first GDI call specifies a first region of a first area to be modified,

the one or more second GDI calls each comprise graphics data related to the first region, and

the third GDI call specifies a second region of a second area to be modified, wherein the second region is not related to the first region.

3. The method of claim 1, wherein the data is rendered to the display after a period of time has passed since receiving the last of the second GDI calls.

4. The method of claim 1, wherein the third GDI call is added to the list of events after the call to the GDI system is performed.

5. The method of claim 2, further comprising:

resetting the GDI system.

6. The method of claim 1, wherein the method is performed by a component of a generic transcoding service.

7. The method of claim 1, wherein the GDI calls are received from an HTTP-compatible client.

8. A system comprising:

one or more processors; and

a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to;

intercept, by an intermediate function, from an application a first graphics device interface (GDI) call after a painting function and before a rendering function;

add the first GDI call to a list of events, wherein each event comprises regionally related graphics data for re-creation;

intercept, by the intermediate function, from the application one or more second GDI calls, wherein each of the second GDI calls is related at least as to a region to the first GDI call;

add the second GDI calls to the list of events;

intercept, by the intermediate function, from the application a third GDI call,

wherein the third GDI call is not related to the first GDI call, wherein intercepting the first GDI call, the one or more second GDI calls and the third GDI call prevents the application from directly accessing a GDI system;

perform a call to the GDI system once the region is fully defined, the call comprising the list of events, wherein the call to the GDI system comprises a single system GDI event; and

render to a display data associated with at least one event of the list of events.

9. The system of claim 8, wherein:

the first GDI call specifies a first region of a first area to be modified,

the one or more second GDI calls each comprise graphics data related to the first region, and

the third GDI call specifies a second region of a second area to be modified, wherein the second region is not related to the first region.

10. The system of claim 8, wherein the data is rendered to the display after a period of time has passed since receiving the last of the second GDI calls.

11. The system of claim 8, wherein the third GDI call is added to the list of events after the call to the GDI system is performed.

12. The system of claim 9, the processors further operable when executing the instructions to:

reset the GDI system.

13. The system of claim 8, wherein the system comprises a component of a generic transcoding service.

14. The system of claim 8, wherein the GDI calls are received from an HTTP-compatible client.

15. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

intercept, by an intermediate function, from an application a first graphics device interface (GDI) call after a painting function and before a rendering function;

add the first GDI call to a list of events, wherein each event comprises regionally related graphics data for re-creation;

intercept, by the intermediate function, from the application one or more second GDI calls, wherein each of the second GDI calls is related at least as to a region to the first GDI call;

add the second GDI calls to the list of events;

intercept, by the intermediate function, from the application a third GDI call, wherein the third GDI call is not related to the first GDI call, wherein intercepting the first GDI call, the one or more second GDI calls and the third GDI call prevents the application from directly accessing a GDI system;

perform a call to the GDI system once the region is fully defined, the call comprising the list of events, wherein the call to the GDI system comprises a single system GDI event; and

render to a display data associated with at least one event of the list of events.

16. The media of claim 15, wherein:

the first GDI call specifies a first region of a first area to be modified,

the one or more second GDI calls each comprise graphics data related to the first region, and

the third GDI call specifies a second region of a second area to be modified, wherein the second region is not related to the first region.

17. The media of claim 15, wherein the data is rendered to the display after a period of time has passed since receiving the last of the second GDI calls.

18. The media of claim 15, wherein the third GDI call is added to the list of events after the call to the GDI system is performed.

19. The media of claim 16, the software further operable when executed to:

reset the GDI system.

20. The media of claim 15, wherein the system comprises a component of a generic transcoding service.
