Constructor Detail

NemaImageGenerator

public NemaImageGenerator(ImageGenerator.Format format)

Creates the vector image generator that encodes the image in the Nema GPU compatible format.

Parameters:

format - the path buffer output format expected by the application; this format is not used and the output format is always ImageGenerator.Format.VG_FP32.

Method Detail

encodeCommand

public int encodeCommand(ImageGenerator.Command command)

Description copied from interface: ImageGenerator

Encodes the GPU command from a ImageGenerator.Command

Specified by:

encodeCommand in interface ImageGenerator

Parameters:

command - the command to convert.

Returns:

GPU command representation.

encodeColor

public int encodeColor(java.awt.Color color,
                       float opacity)

Description copied from interface: ImageGenerator

Encodes the GPU color from a Color and an opacity.

Specified by:

encodeColor in interface ImageGenerator

Parameters:

color - the color to convert.

opacity - the opacity to apply, a value between 0f and 1f.

Returns:

GPU color representation.

encodePath

public byte[] encodePath(Path path)

Description copied from interface: ImageGenerator

Encodes a path for the GPU (path header + path commands + path commands parameters).

The Path.encode(PathData) method should be used to browse the commands of the path. These commands are encoded by ImageGenerator.encodeCommand(Command) and append to the associated path data.

Specified by:

encodePath in interface ImageGenerator

Parameters:

path - the path to encode

Returns:

the encoded path

encodeGradient

public byte[] encodeGradient(LinearGradient gradient)

Description copied from interface: ImageGenerator

Encodes a linear gradient for the GPU.

Specified by:

encodeGradient in interface ImageGenerator

Parameters:

gradient - the gradient to encode

Returns:

GPU linear gradient representation
