Constructor Detail

ByteTextureComponent2D

public ByteTextureComponent2D()

Constructs an image with default values.

ByteTextureComponent2D

public ByteTextureComponent2D(boolean yUp)

Constructs an image with default values.

Parameters:

yUp - Change the image aroud the Y axis if needed

ByteTextureComponent2D

public ByteTextureComponent2D(int format,
                              int width,
                              int height,
                              byte[] srcPixels)

Constructs an Image2D using the specified format, width, height and rendered image. If the srcImage[0] is an instance of BufferedImage, the format passed is ignored and the image directly used.

Parameters:

format - The image format. RGB, RGBA currently

width - The width of the image

height - The height of the image

srcPixels - The image data

ByteTextureComponent2D

public ByteTextureComponent2D(int format,
                              int width,
                              int height,
                              byte[][] srcPixels,
                              int numLevels)

Constructs an Image2D using the specified format, width, height and rendered image. If the srcImage[0] is an instance of BufferedImage, the format passed is ignored and the image directly used.

Parameters:

format - The image format. RGB, RGBA currently

width - The width of the image

height - The height of the image

srcPixels - The image data

numLevels - The number of mip-map levels to generate

ByteTextureComponent2D

public ByteTextureComponent2D(int format,
                              int width,
                              int height,
                              byte[] srcPixels,
                              boolean yUp)

Constructs an Image2D using the specified format, width, height and rendered image. If the srcImage[0] is an instance of BufferedImage, the format passed is ignored and the image directly used.

Parameters:

format - The image format. RGB, RGBA currently

width - The width of the image

height - The height of the image

srcPixels - The image data

yUp - Change the image aroud the Y axis if needed

Method Detail

updateSubImage

public void updateSubImage(int destX,
                           int destY,
                           int width,
                           int height,
                           int level,
                           byte[] img)
                    throws InvalidWriteTimingException

Update a sub-section of the image data with the new pixel values. Not implemented yet.

Parameters:

destX - The starting X offset in the existing image space

destY - The starting Y offset in the existing image space

width - The width of the section to replace

height - The height of the section to replace

level - The mipmap level to update

img - The image to take data from

Throws:

InvalidWriteTimingException - An attempt was made to write outside of the NodeUpdateListener callback method

clearLocalData

public void clearLocalData()

Clear local data stored in this node. Only data needed for OpenGL calls will be retained;

Specified by:

clearLocalData in class TextureComponent

convertImage

protected java.nio.ByteBuffer convertImage(int level)

Convenience method to convert a buffered image into a NIO array of the corresponding type. Images typically need to be swapped when doing this by the Y axis is in the opposite direction to the one used by OpenGL.

Specified by:

convertImage in class TextureComponent

Parameters:

level - Which image level needs to be converted

Returns:

an appropriate array type - either IntBuffer or ByteBuffer
