Abstract

An approach is provided for rendering content based on chunks and layers. A request is received to render content at a device. One or more layers of the content are determined. One or more patterns are determined corresponding to one or more of the layers. One or more chunks are determined based, at least in part, on the one or more patterns. At least one of the layers and corresponding one or more chunks are determined to be rendered separately from the other layers.

Claims

1. A method comprising:

receiving a request to render content at a device;

determining one or more layers of the content;

determining one or more patterns of the content corresponding to one or more of the layers;

determining one or more chunks based, at least in part, on the one or more patterns; and

determining to render at least one of the layers and the corresponding one or more chunks separately from the other layers.

2. A method of claim 1, further comprising:

receiving an input specifying a portion of the content for display; and

determining the one or more chunks based, at least in part, on the input.

3. A method of claim 1, wherein at least one of the patterns is a repeatable geometry-based pattern.

4. A method of claim 1, further comprising:

determining to cache the one or more chunks at a rendering engine,

wherein the rendering of the at least one of the layers is based, at least in part, on the one or more cached chunks.

5. A method of claim 4, further comprising:

determining to recycle the one or more cached chunks for subsequent renderings of the content or a portion of the content.

6. A method of claim 1, wherein the content represents a scrollable list of a plurality of items, and wherein at least one of the chunks represents multiple ones of the items.

7. A method of claim 6, further comprising:

receiving an input specifying a scroll range corresponding to the scrollable list;

determining a set of the items within the scroll range; and

determining the one or more chunks based, at least in part, on the set of the items.

8. A method of claim 1, wherein the one or more layers include a background layer, a foreground layer, a variable content layer, or a combination thereof.

9. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

receive a request to render content at a device;

determine one or more layers of the content;

determine one or more patterns of the content corresponding to one or more of the layers;

determine one or more chunks based, at least in part, on the one or more patterns; and

determine to render at least one of the layers and the corresponding one or more chunks separately from the other layers.

10. An apparatus of claim 9, wherein the apparatus is further caused to:

receive an input specifying a portion of the content for display; and

determine the one or more chunks based, at least in part, on the input.

11. An apparatus of claim 9, wherein at least one of the patterns is a repeatable geometry-based pattern.

12. An apparatus of claim 9, wherein the apparatus is further caused to:

determine to cache the one or more chunks at a rendering engine,

wherein the rendering of the at least one of the layers is based, at least in part, on the one or more cached chunks.

13. An apparatus of claim 12, wherein the apparatus is further caused to:

determine to recycle the one or more cached chunks for subsequent renderings of the content or a portion of the content.

14. An apparatus of claim 9, wherein the content represents a scrollable list of a plurality of items, and wherein at least one of the chunks represents multiple ones of the items.

15. An apparatus of claim 14, wherein the apparatus is further caused to:

receive an input specifying a scroll range corresponding to the scrollable list;

determine a set of the items within the scroll range; and

determine the one or more chunks based, at least in part, on the set of the items.

16. An apparatus of claim 9, wherein the one or more layers include a background layer, a foreground layer, a variable content layer, or a combination thereof.

17. A computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:

receiving a request to render content at a device;

determining one or more layers of the content;

determining one or more patterns of the content corresponding to one or more of the layers;

determining one or more chunks based, at least in part, on the one or more patterns; and

determining to render at least one of the layers and the corresponding one or more chunks separately from the other layers.

18. A computer-readable storage medium of claim 17, wherein the apparatus is further caused to perform:

receiving an input specifying a portion of the content for display; and

determining the one or more chunks based, at least in part, on the input.

19. A computer-readable storage medium of claim 17, wherein at least one of the patterns is a repeatable geometry-based pattern.

20. A computer-readable storage medium of claim 17, wherein the apparatus is further caused to perform:

determining to cache the one or more chunks at a rendering engine,

wherein the rendering of the at least one of the layers is based, at least in part, on the one or more cached chunks.
