com.sun.media.imageioimpl.plugins.jpeg2000.ChannelDefinitionBox
| ChannelDefinitionBox | | public class ChannelDefinitionBox extends Box (Code) | | This class is designed to represent a Channel Definition Box of
JPEG JP2 file format. A Channel Definition Box has a length, and
a fixed type of "cdef". Its content defines the type of the image
channels: color channel, alpha channel or premultiplied alpha channel.

| Constructor Summary | |
| public | ChannelDefinitionBox(ColorModel colorModel)
Constructs a ChannelDefinitionBox based on the provided
ColorModel. | | public | ChannelDefinitionBox(byte[] data)
Constructs a ChannelDefinitionBox based on the provided
content in byte array. | | public | ChannelDefinitionBox(short[] channel, short[] types, short[] associations)
Constructs a ChannelDefinitionBox based on the provided
channel definitions. | | public | ChannelDefinitionBox(Node node)
Constructs a ChannelDefinitionBox based on the provided
org.w3c.dom.Node. |
| Method Summary | |
| protected void | compose()
| | public static void | fillBasedOnBands(int numComps, boolean isPremultiplied, short[] c, short[] t, short[] a)
Fills the channel definitions into the arrays based on the number
of components and isPremultiplied. | | public short[] | getAssociation()
Returns the association which associates a color channel to a color
component in the color space of the image. | | public short[] | getChannel()
Returns the defined channels. | | public IIOMetadataNode | getNativeNode()
Creates an IIOMetadataNode from this channel definition
box. | | public short[] | getTypes()
Returns the channel types. | | protected void | parse(byte[] data)
Parse the channel definitions from the content data array. |
| ChannelDefinitionBox | | public ChannelDefinitionBox(ColorModel colorModel)(Code) | | Constructs a ChannelDefinitionBox based on the provided
ColorModel.
|
| ChannelDefinitionBox | | public ChannelDefinitionBox(byte[] data)(Code) | | Constructs a ChannelDefinitionBox based on the provided
content in byte array.
|
| ChannelDefinitionBox | | public ChannelDefinitionBox(short[] channel, short[] types, short[] associations)(Code) | | Constructs a ChannelDefinitionBox based on the provided
channel definitions.
|
| ChannelDefinitionBox | | public ChannelDefinitionBox(Node node) throws IIOInvalidTreeException(Code) | | Constructs a ChannelDefinitionBox based on the provided
org.w3c.dom.Node.
