Field Detail
DEFAULT_PALETTE_NAME
final public static String DEFAULT_PALETTE_NAME(Code)
The name of the default color palette to apply when none was explicitly specified.

Constructor Detail
GeographicImageReadParam
public GeographicImageReadParam(ImageReader reader)(Code)
Creates a new, initially empty, set of parameters.
Parameters:
  reader - The reader for which this parameter block is created




Method Detail
getNonNullPaletteName
final String getNonNullPaletteName()(Code)
Returns a name of the color palette, or a if none were explicitly specified.



getPaletteName
public String getPaletteName()(Code)
Returns the name of the color palette to apply when creating an . This is the name specified by the last call to GeographicImageReadParam.setPaletteName .



getVisibleBand
public int getVisibleBand()(Code)
Returns the band to display in the target image. In theory, images backed by should have only ony band. But sometime we want to load additional bands as numerical data, in order to perform computations. In such case, we need to specify which band in the destination image will be used as an index for displaying the colors. The default value is 0.



setPaletteName
public void setPaletteName(String palette)(Code)
Sets the color palette as one of the provided by the . This name will be given by the GeographicImageReader default implementation to the for creating a .
See Also:   PaletteFactory.getAvailableNames



setVisibleBand
public void setVisibleBand(int visibleBand) throws IllegalArgumentException(Code)
Sets the band to make visible in the destination image.
Parameters:
  visibleBand - The band to make visible.
throws:
  IllegalArgumentException - if the specified band index is invalid.



toString
public String toString()(Code)
Returns a string representation of this block of parameters.
