Abstract

There is provided an information processing apparatus that enables three-dimensional rendering of an image corresponding to two-dimensional vector-based data with a relatively simple technique. The information processing apparatus includes a first generation unit configured to generate from vector-based graphics data a first coordinate data group at boundary portions of a first image to be rendered based on the graphics data, a second generation unit configured to generate a second coordinate data group by applying a graphics conversion rule to the first coordinate data group to transform the first image to obtain a second image, and a rendering unit configured to render the second image in bitmap form based on the second coordinate data group.

Claims

1. An information processing apparatus, comprising:

a first generation unit configured to generate from vector-based graphics data a first coordinate data group at boundary portions of a first image to be rendered based on the graphics data;

a second generation unit configured to generate a second coordinate data group by applying a graphics conversion rule to the first coordinate data group to transform the first image to obtain a second image; and

an output unit configured to output a second vector-based graphics data group for rendering the second image based on the second coordinate data group.

2. An information processing apparatus, comprising:

a first generation unit configured to generate from vector-based graphics data a first coordinate data group at boundary portions of a first image to be rendered based on the graphics data;

a second generation unit configured to generate a second coordinate data group by applying a graphics conversion rule to the first coordinate data group to transform the first image to obtain a second image; and

a rendering unit configured to render the second image in bitmap form based on the second coordinate data group.

3. The information processing apparatus according to claim 2, wherein the first generation unit generates the first coordinate data group based on attribute values of the vector-based graphics data.

4. The information processing apparatus according to claim 2, wherein the first generation unit generates the first coordinate data group so that areas surrounded by coordinate values of the first coordinate data group are filled with the same single color.

5. The information processing apparatus according to claim 2, wherein the graphics conversion rule performs three-dimensional coordinate conversion on the vector-based graphics data.

6. The information processing apparatus according to claim 2, wherein the first generation unit generates the first coordinate data group at boundary portions of the first image based on a predetermined tolerance rule.

7. The information processing apparatus according to claim 2, wherein the first generation unit generates the first coordinate data group as path data.

8. The information processing apparatus according to claim 2, wherein the vector-based graphics data is line data defined by path information and line width information, and

wherein the first generation unit generates the first coordinate values based on the path information and line width information.

9. The information processing apparatus according to claim 2, further comprising:

a determination unit configured to determine whether the second image is to be rendered as animation based on the graphics data by the rendering unit,

wherein if the determination unit determines that the second image is to be rendered as animation, then the first generation unit does not generate the first coordinate data group for strokes in the graphics data.

10. A method for processing information, comprising:

generating from vector-based graphics data a first coordinate data group at boundary portions of a first image to be rendered based on the graphics data;

generating a second coordinate data group by applying a graphics conversion rule to the first coordinate data group to transform the first image to obtain a second image; and

rendering the second image in bitmap form based on the second coordinate data group.

11. A computer-readable storage medium storing a computer program, which when executed by one or more processors implements a method comprising:

generating from vector-based graphics data a first coordinate data group at boundary portions of a first image to be rendered based on the graphics data;

generating a second coordinate data group by applying a graphics conversion rule to the first coordinate data group to transform the first image to obtain a second image; and

rendering the second image in bitmap form based on the second coordinate data group.
