Abstract

In one embodiment, dividing a set of texts into one or more text blocks, each text block including a portion of the set of texts; rendering each text block to obtain one or more rendered text blocks; determining a placement instruction for each rendered text block, the placement instruction indicating a position of the rendered text block when it is displayed; and sending the one or more rendered text blocks and their respectively associated placement instructions to a electronic device for displaying on the electronic device.

Claims

1. A method comprising:

by one or more computing devices,

dividing a set of texts into one or more text blocks, each text block including a portion of the set of texts;

rendering each text block to obtain one or more rendered text blocks;

determining a placement instruction for each rendered text block, the placement instruction indicating a position of the rendered text block when it is displayed; and

sending the one or more rendered text blocks and their respectively associated placement instructions to a electronic device for displaying on the electronic device.

2. The method of claim 1, wherein dividing the set of texts into one or more text blocks comprises:

dividing the set of texts into one or more text units; and

dividing each text unit into at least one of the one or more text blocks.

3. The method of claim 2, wherein:

the set of texts is in an alphabet-based language; and

each text unit is an individual alphabet.

4. The method of claim 2, wherein:

the set of texts is in a character-based language; and

each text unit is an individual character.

5. The method of claim 2, wherein:

the set of texts is in a script-based language; and

each text unit is an individual symbol.

6. The method of claim 1, wherein the one or more text blocks includes all portions of the set of texts.

7. The method of claim 1, wherein:

a first text block includes a first portion of the set of texts;

a second text block includes a second portion of the set of text; and

the first portion and the second portion partially overlap with each other.

8. The method of claim 1, wherein the set of texts is divided into the one or more text blocks based on a Unicode representation of the set of texts.

9. The method of claim 1, wherein the set of texts is divided into the one or more text blocks based on a structure of a written language that the set of texts is in.

10. The method of claim 1, further comprising selecting one or more reference coordinates for the set of texts.

11. The method of claim 10, wherein determining a placement instruction for each rendered text block comprises:

selecting one of the one or more reference coordinates that is closest to the rendered text block; and

determining, as an offset of the rendered text block, a vector that begins at the selected one reference coordinate and ends at a lower-left corner of the rendered text block.

12. The method of claim 1, further comprising compressing each rendered text blocks, wherein the one or more rendered text blocks are sent to the electronic device in a compressed form.

13. The method of claim 1, further comprising compiling the set of texts.

14. The method of claim 1, further comprising receiving, from the electronic device, data representing the set of texts, wherein the set of texts is inputted to the electronic device by a user of the electronic device.

15. The method of claim 1, wherein the electronic device is a mobile device.

16. A system comprising:

a memory comprising instructions executable by one or more processors; and

the one or more processors coupled to the memory and operable to execute the instructions, the one or more processors being operable when executing the instructions to;

divide a set of texts into one or more text blocks, each text block including a portion of the set of texts;

render each text block to obtain one or more rendered text blocks;

determine a placement instruction for each rendered text block, the placement instruction indicating a position of the rendered text block when it is displayed; and

send the one or more rendered text blocks and their respectively associated placement instructions to a electronic device for displaying on the electronic device.

17. The system of claim 16, wherein dividing the set of texts into one or more text blocks comprises:

dividing the set of texts into one or more text units; and

dividing each text unit into at least one of the one or more text blocks.

18. The system of claim 16, wherein the one or more text blocks includes all portions of the set of texts.

19. The system of claim 16, wherein the one or more processors are further operable when executing the instructions to compress each rendered text blocks, wherein the one or more rendered text blocks are sent to the electronic device in a compressed form.

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

divide a set of texts into one or more text blocks, each text block including a portion of the set of texts;

render each text block to obtain one or more rendered text blocks;

determine a placement instruction for each rendered text block, the placement instruction indicating a position of the rendered text block when it is displayed; and

send the one or more rendered text blocks and their respectively associated placement instructions to a electronic device for displaying on the electronic device.
