Method Detail

getSubTileWidth

public int getSubTileWidth()

Description copied from interface: ILcdSubtiledTile

Returns the width of a subtile in pixels. May be equal to the width of the parent tile (as returned by the getWidth() method), in which case the tile is not subdivided.

Specified by:

getSubTileWidth in interface ILcdSubtiledTile

getSubTileHeight

public int getSubTileHeight()

Returns the height of a subtile in pixels. May be equal to the height of the parent tile (as returned by the getHeight() method), in which case the tile is not subdivided.

Specified by:

getSubTileHeight in interface ILcdSubtiledTile

getWidth

public int getWidth()

Returns the width of the tile, expressed in pixels.

Specified by:

getWidth in interface ILcdTile

getHeight

public int getHeight()

Returns the height of the tile, expressed in pixels.

Specified by:

getHeight in interface ILcdTile

getType

public int getType()

Returns the internal storage type of the tile values.

Specified by:

getType in interface ILcdTile

Returns:

one of BYTE, SHORT, or INT.

getPixelSize

public int getPixelSize()

Returns the pixel size of the tile values, expressed in bits.

Specified by:

getPixelSize in interface ILcdTile

getColorModel

public ColorModel getColorModel()

Returns the optional color model of the tile.

Specified by:

getColorModel in interface ILcdTile

Returns:

the color model, or null if the raster doesn't have an explicit color model.

isAllDefault

public boolean isAllDefault()

Returns whether all values in the tile are equal to a default value.

Specified by:

isAllDefault in interface ILcdTile

retrieveValue

public int retrieveValue(int aX,
                         int aY)

Retrieves the tile value at the specified location.

Specified by:

retrieveValue in interface ILcdTile

Parameters:

aX - the x ordinate of the value, expressed in tile coordinates.

aY - the y ordinate of the value, expressed in tile coordinates.

Returns:

the integer tile value at the specified location.

createImage

public Image createImage()

Creates an image of the entire tile, using the tile's own color model.

Specified by:

createImage in interface ILcdTile

createImage

public Image createImage(ColorModel aColorModel)

Creates an image of the entire tile, using the given color model.

Specified by:

createImage in interface ILcdTile

Parameters:

aColorModel - the color model to be used for the image. The color model should be compatible with the pixel values of the tile.

createImage

public Image createImage(int aX,
                         int aY,
                         int aWidth,
