Abstract

Vector-based images and documents, such as those written in SVG and Adobe Flash, can be converted into equivalent bitmap or other non-vector-based image by parsing the vector-based image to detect objects in the vector-based code. For each detected object, a separate bitmap of the object is created and information about where that image lies on the z-axis is retained. A separate bitmap image is created for each object, and the separate bitmap images are layered on top of one another, which is to say ordered along the z-axis in accordance with their z-axis coordinates. Animation of an image can be implemented by selectively rendering different ones of the bitmap images as transparent.

Claims

1. A method of translating at least one image object in a document written in a vector-based computer-readable language into a corresponding image object in a document written in a bitmap-based computer-readable language, comprising:

detecting at least one object identifier associated with at least one respective object in the vector-based document; and

generating a bitmap of the at least one object corresponding to the detected at least one object identifier, wherein the generated bitmap retains from the vector-based document information about a position of the bitmap along an axis perpendicular to a plane of the document, and the information includes an order of objects in the vector-based document that determines the objects'"'"' positions along the axis.

2. The method of claim 1, wherein generating the bitmap comprises determining a bounding box of the object, and rasterizing a region of the document determined by the bounding box.

3. The method of claim 1, wherein a plurality of object identifiers associated with a like plurality of respective objects are detected, and respective bitmaps of the plurality of objects are generated, and the method further comprises layering the bitmaps along the axis based on their respective coordinates.

4. The method of claim 3, further comprising selecting a transparency property of at least one layered bitmap.

5. The method of claim 1, wherein the bitmap is positioned in the document written in the bitmap-based language by absolute positioning.

6. The method of claim 1, further comprising explicitly setting a position of the bitmap along the axis.

7. A programmable electronic processor, comprising:

a processing unit configured to execute instructions such that the processor translates at least one image object in a document written in a vector-based processor-readable language into a corresponding image object in a document written in a bitmap-based processor-readable language; and

an application memory configured to store instructions executed by the processing unit;

wherein the processing unit is configured to perform the following actions;

detecting at least one object identifier associated with at least one respective object in the vector-based document; and

generating a bitmap of the at least one object corresponding to the detected at least one object identifier, wherein the generated bitmap retains from the vector-based document information about a position of the bitmap along an axis perpendicular to a plane of the document, and the information includes an order of objects in the vector-based document that determines the objects'"'"' positions along the axis.

8. The programmable electronic processor of claim 7, wherein the processing unit is configured to generate the bitmap by at least determining a bounding box of the object, and rasterizing a region of the document determined by the bounding box.

9. The programmable electronic processor of claim 7, wherein the processing unit is further configured to layer a plurality of bitmaps along the axis based on their respective coordinates.

10. The programmable processor of claim 9, wherein the processing unit is further configured to select a transparency property of at least one of the layered bitmaps.

11. The programmable processor of claim 7, wherein the processing unit is configured to position the bitmap in the document written in the bitmap-based language by absolute positioning.

12. The programmable processor of claim 7, wherein the processing unit is configured to set a predetermined position of the bitmap along the axis.

13. A computer-readable medium having stored instructions that, when executed, cause the computer to carry out a method of translating at least one image object in a document written in a vector-based computer-readable language into a corresponding image object in a document written in a bitmap-based computer-readable language, wherein the method comprises:

detecting at least one object identifier associated with at least one respective object in the vector-based document; and

generating a bitmap of the at least one object corresponding to the detected at least one object identifier, wherein the generated bitmap retains from the vector-based document information about a position of the bitmap along an axis perpendicular to a plane of the document, and the information includes an order of objects in the vector-based document that determines the objects'"'"' positions along the axis.

14. The method of claim 13, wherein generating the bitmap comprises determining a bounding box of the object, and rasterizing a region of the document determined by the bounding box.

15. The method of claim 13, wherein a plurality of object identifiers associated with a like plurality of respective objects are detected, and respective bitmaps of the plurality of objects are generated, and the method further comprises layering the bitmaps along the axis based on their respective coordinates.

16. The method of claim 15, wherein the method further comprises selecting a transparency property of at least one layered bitmap.

17. The method of claim 13, wherein the bitmap is positioned in the document written in the bitmap-based language by absolute positioning.

18. The method of claim 13, wherein the method further comprises explicitly setting a position of the bitmap along the axis.
