Abstract

The present disclosure includes systems and methods relating to accelerating initialization of image viewers. In general, one aspect of the subject matter described in this specification can be embodied in a method that includes receiving a request to display an image, identifying a data component involved with displaying the image, modifying an existing electronic binary vector graphics file to include the data component, and transmitting the modified file.

Claims

1. A computer program product, encoded on a non-transitory computer-readable medium, operable to cause data processing apparatus to perform operations comprising:

identifying a first electronic file associated with an image viewer conforming to a binary vector graphics file format;

parsing the first electronic file into a plurality of objects;

identifying, in response to a request for an image from a user device, one or more objects needed for viewing the requested image on the user device using the image viewer;

manipulating the plurality of objects to generate a modified plurality of objects based on the identified one or more objects needed for viewing the requested image on the user device, wherein manipulating the plurality of objects includes removing at least one object from the plurality of objects or adding at least one object to the plurality of objects to generate the modified plurality of objects; and

linking the modified plurality of objects to create a second electronic file conforming to a SWF proprietary vector graphics file format.

2. The computer program product of claim 1, wherein manipulating the plurality of objects comprises removing at least one object.

3. The computer program product of claim 1, wherein manipulating the plurality of objects comprises adding at least one object.

4. The computer program product of claim 1, wherein manipulating the plurality of objects comprises modifying a content of at least one object.

5. The computer program product of claim 1, wherein at least one of the plurality of objects corresponds to a SWF data structure.

6. The computer program product of claim 5, wherein the SWF data structure comprises a SWF tag.

7. The computer program product of claim 1, the operations further comprising:

replacing simple numerical references in the first electronic file with direct object references prior to manipulating the plurality of objects.

8. The computer program product of claim 1, the operations further comprising:

providing the second electronic file to an application adapted to execute the second electronic file.

9. The computer program product of claim 8, wherein the image viewer is invoked during execution of the second electronic file.

10. The computer program product of claim 1, wherein the binary vector graphics file format comprises a SWF file format.

11. A computer-implemented method comprising:

identifying a first electronic file associated with an image viewer conforming to a binary vector graphics file format;

parsing the first electronic file into a plurality of objects;

identifying, in response to a request for an image from a user device, one or more objects needed for viewing the requested image on the user device using the image viewer;

manipulating the plurality of objects to generate a modified plurality of objects based on the identified one or more objects needed for viewing the requested image on the user device, wherein manipulating the plurality of objects includes removing at least one object from the plurality of objects or adding at least one object to the plurality of objects to generate the modified plurality of objects; and

linking the modified plurality of objects to create a second electronic file conforming to a SWF proprietary vector graphics file format.

12. The method of claim 11, wherein manipulating the plurality of objects comprises at least one of:

removing at least one object;

adding at least one object;

or

modifying a content of at least one object.

13. The method of claim 11, wherein at least one of the plurality of objects corresponds to a SWF data structure.

14. The method of claim 13, wherein the SWF data structure comprises a SWF tag.

15. The method of claim 11, further comprising:

replacing simple numerical references in the first electronic file with direct object references prior to manipulating the plurality of objects.

16. The method of claim 11, further comprising:

providing the second electronic file to an application adapted to execute the second electronic file.

17. The method of claim 16, wherein the image viewer is invoked during execution of the second electronic file.

18. The method of claim 11, wherein the binary vector graphics file format comprises a SWF file format.

19. A system comprising:

a non-transitory computer-readable medium storing a first electronic file associated with an image viewer conforming to a binary vector graphics file format; and

data processing apparatus operable to perform operations comprising;

parsing the first electronic file into a plurality of objects;

identifying, in response to a request for an image from a user device, one or more objects needed for viewing the requested image on the user device using the image viewer;

manipulating the plurality of objects to generate a modified plurality of objects based on the identified one or more objects needed for viewing the requested image on the user device, wherein manipulating the plurality of objects includes removing at least one object from the plurality of objects or adding at least one object to the plurality of objects to generate the modified plurality of objects; and

linking the modified plurality of objects to create a second electronic file conforming to a SWF proprietary vector graphics file format.

20. The system of claim 19, wherein manipulating the plurality of objects comprises at least one of:

removing at least one object;

adding at least one object;

or

modifying a content of at least one object.

21. A computer program product, encoded on a non-transitory computer-readable medium, operable to cause data processing apparatus to perform operations comprising:

receiving a request to retrieve an existing electronic file for displaying an image on a client device, the existing electronic file conforming to a file format for presenting multimedia content using content player software on the client device;

analyzing at least one of the request or the existing electronic file to identify at least one data component necessary to display the image, the at least one identified data component providing data for use by the content player software, in combination with the existing electronic file, to generate the image, wherein the at least one identified data component includes at least one of skin data or image viewer configuration data;

modifying the electronic file to include the at least one identified data component; and

transmitting the modified electronic file to the client device in response to the request.

22. The computer program product of claim 21, wherein the electronic file comprises a main file for displaying the image, the operations further comprising:

identifying, based upon the request or upon contents of the electronic file, at least one component of the image viewer nonessential for displaying the image; and

modifying the electronic file to remove the at least one nonessential component.

23. The computer program product of claim 21, the operations further comprising:

determining, based upon the request or upon contents of the electronic file, layout information associated with displaying the image;

performing one or more computations to determine layout data based on the layout information; and

modifying the electronic file to include the layout data.

24. The computer program product of claim 21, the operations further comprising:

marking the modified electronic file as cacheable; and

caching the modified electronic file on a Content Delivery Network (CDN).

25. The computer program product of claim 21, wherein the file format comprises a small web format (SWF) file format.

26. The computer program product of claim 21, wherein:

the electronic file includes a loader for loading a main file for displaying the image, and the at least one identified data component includes one or more components unique to the image.

27. The computer program product of claim 21, wherein:

the electronic file includes a main file for displaying the image, and

the at least one identified data component comprises one or more components for use with a plurality of images.
