Abstract

Techniques are disclosed for render documents that are in proprietary formats in a browser or mobile device. In one embodiment, a method comprises converting a plurality of resources in a document file into a plurality of files that are native to a browser. The method further comprises creating a style sheet based on the document file, wherein an aggregate of the plurality of files together with the style sheet are configured to cause the browser to render an appearance of the document file. The method further comprises generating, based on the document file, an invisible layer to be laid on the appearance, wherein the invisible layer enables actions to be performed on the document file. Among other advantages, embodiments disclosed herein provide the convenience of viewing and accessing documents regardless of whether a software or plug-in therefor is installed.

2. The method of claim 1, further comprising:

streaming pages of the document file to the browser individually as each page is processed.

3. The method of claim 1, wherein the plurality of resources comprise a font, the method further comprising:

extracting the font from the document file; and

creating a blank variation of the font so as to enable the generation of the invisible layer, wherein glyphs within the blank variation of the font contain no outline information.

4. The method of claim 1, wherein the plurality of resources comprise an image, the method further comprising:

extracting the image from the document file; and

down-sampling the image if a size of the image is larger than a predetermined number.

5. The method of claim 1, wherein the plurality of resources comprise a graphic, the method further comprising:

mapping the graphic to an equivalent scalable vector graphic operation.

6. The method of claim 1, wherein the plurality of resources comprise text, the method further comprising:

mapping the text using to a plurality of equivalent scalable vector graphic operations; and

providing the text for the generation of the invisible layer.

7. The method of claim 1, wherein the document file is received from a third-party software application via an application programming interface (API).

8. The method of claim 1, wherein the browser is to render the appearance of the document file regardless of whether a plug-in software that supports the document file is installed for the browser.

9. The method of claim 1, wherein the invisible layer comprises a HyperText Markup Language (HTML) page.

10. The method of claim 1, wherein the actions to be performed on the document file includes one or more of text selecting, text copying, text cutting, text pasting, text searching, text filling, and hyperlinking.

11. The method of claim 1, wherein a file type of the document file includes one or more of Portable Document Format file (PDF), Word Document file (DOC), PowerPoint Presentation file (PPT), Excel worksheet file (XLS).

12. The method of claim 1, wherein the rendering is performed by a server which hosts a cloud-based environment shared among a user and collaborators of the user.

13. The method of claim 12, wherein the cloud-based environment includes a cloud-based collaboration environment, a cloud-based storage service or file sharing service.

14. A computer server which hosts a cloud-based environment shared among a user and collaborators of the user, the server comprising:

a processor; and

a memory unit having instructions stored thereon which when executed by the processor, causes the processor to;

convert a plurality of resources in a document file into a plurality of files that are native to a browser;

create a style sheet based on the document file, wherein an aggregate of the plurality of files together with the style sheet are configured to cause the browser to render an appearance of the document file; and

generate, based on the document file, an invisible layer to be laid on the appearance, wherein the invisible layer enables actions to be performed on the document file.

15. The server of claim 14, wherein the processor is further caused to:

stream pages of the document file to the browser individually as each page is processed.

16. The server of claim 14, wherein the plurality of resources comprise a font, and wherein the processor is further caused to:

extract the font from the document file; and

create a blank variation of the font so as to enable the generation of the invisible layer, wherein glyphs within the blank variation of the font contain no outline information.

17. The server of claim 14, wherein the plurality of resources comprise an image, and wherein the processor is further caused to:

extract the image from the document file; and

down-sample the image if a size of the image is larger than a predetermined number.

18. The server of claim 14, wherein the plurality of resources comprise a graphic, and wherein the processor is further caused to:

map the graphic to an equivalent scalable vector graphic operation.

19. The server of claim 14, wherein the plurality of resources comprise text, and wherein the processor is further caused to:

map the text using to a plurality of equivalent scalable vector graphic operations; and

provide the text for the generation of the invisible layer.

20. The server of claim 14, wherein the document file is received from a third-party software application via an application programming interface (API).

21. The server of claim 14, wherein the browser is to render the appearance of the document file regardless of whether a plug-in software that supports the document file is installed for the browser.

22. The server of claim 14, wherein the invisible layer comprises a HyperText Markup Language (HTML) page.

23. A machine-readable storage medium having stored thereon instructions which, when executed by a processor on a server, cause the processor to:

convert a plurality of resources in a document file into a plurality of files that are native to a browser;

create a style sheet based on the document file, wherein an aggregate of the plurality of files together with the style sheet are configured to cause the browser to render an appearance of the document file; and

generate, based on the document file, an invisible layer to be laid on the appearance, wherein the invisible layer enables actions to be performed on the document file.

24. The medium of claim 23, wherein the processor is further caused to:

stream pages of the document file to the browser individually as each page is processed.

25. The medium of claim 23, wherein the plurality of resources comprise a font, and wherein the processor is further caused to:

extract the font from the document file; and

create a blank variation of the font so as to enable the generation of the invisible layer, wherein glyphs within the blank variation of the font contain no outline information.
