Abstract

A data structure includes entries corresponding to a plurality of tiles that form part of an image, where a given entry of the entries includes color information for a given tile of the plurality of tiles. Image data in the given tile is created using the color information of the given entry, where creating the image data in the given tile using the color information of the given entry is performed without using input image data for the given tile.

Claims

1. A method comprising;

accessing, by a device including a processor, a data structure including entries corresponding to a plurality of tiles that form part of an image, wherein a given entry of the entries includes color information for a given tile of the plurality of tiles;

creating, by the device, image data in the given tile using the color information of the given entry as part of producing the image, wherein creating the image data in the given tile using the color information of the given entry is performed without using input image data for the given tile;

accessing color specified by the color information of the given, entry, and which second portions of the given tile are not to be filled with the color specified by the color information of the given entry, wherein creating the image data in the given tile uses the mask data.

2. The method of claim 1, wherein the mask data includes a plurality of indicators for respective portions of the given die, each of the plurality indicators settable to a first value to specify that a corresponding portion of the given tile is to be filled with the color specified by the color information of the given entry, and a second value to specify that a corresponding portion of the given tile is not to be filled with the color specified by the color information of the given entry.

3. The method of claim 2, wherein the plurality of indicators include a plurality of bits for respective pixels or groups of pixels of the given tile.

4. The method of claim 1, wherein a second entry of the entries of the data structure includes second color information for a second tile of the plurality of tiles, the method further comprising:

creating, by the device, image data in the second tile using the second color information of the second entry as part of producing the image, wherein creating the image data in the second tile using the second color information of the second entry is performed without using input image data for the second tile.

5. The method of claim 1, further comprising blending the created image data for the given tile with a background image to overlay the created image data over the background image.

6. The method of claim 1, further comprising:

receiving an input image data portion for a further tile of the plurality of tiles;

creating image data for the further tile using the received image data portion; and

compressing the further tile and storing the compressed further tile in a memory.

7. The method of claim 6, further comprising storing the given tile in the memory without compressing the given tile.

8. The method of claim 1, wherein the given entry of the data structure includes an indicator settable to a first value to specify that an element of the data structure contains the color information, and settable to a second, different value to specify that the element of the data structure contains a pointer to an input image data portion,

wherein creating the image in the given tile using the color information is in response to determining that the indicator is set to the first value.

9. A device comprising:

a memory to store image data for a first tile of a plurality of tiles for an image, and to store a data structure that links the plurality of tiles to form the image, the data structure including a first entry for the first tile, and a second entry for a second tile of the plurality of tiles; and

a controller to;

as part of producing the image,

create the image data for the first tile using an input image data portion; and

create image data for the second tile using color information in the second entry, wherein creating the image data in the second tile using the color information in the second entry is performed without using any input image data for the second tile, and wherein creating the image data in the second tile comprises accessing mask data indicting which portions of the second tile are to be filled with a color specified by the color information, and which other portions of the second tile are not to be filled with the color specified by the color information.

10. The device of claim 9, wherein the first entry of the data structure includes a pointer to the image data stored in the memory, and the second entry of the data structure includes the color information.

11. The device of claim 10, wherein the first entry includes an indicator set to a first value to specify that the first entry contains the pointer, and the second entry includes an indicator set to a second, different value to specify that the second entry contains the color information.

12. An article comprising;

at least one non-transitory machine-readable storage medium storing instructions that upon execution cause a device to;

access a data structure including entries containing respective location information specifying positions of titles within an image, wherein a given entry of the entries includes color information for a given tile of the plurality of tiles;

access mask data specifying which first portions of the given tile are to be filled with a color specified by the color information of the given entry, and which second portions of the given tile are not to be filled with, the color specified by the color information of the given entry, wherein creating the image data in the given tile uses the mask data; and

create image data in the given tile using the color information of the given entry as part of producing the image, wherein creating the image data in the given tile using the color information of the given entry”

is performed without using input image data for the given tile.
