Class Colorizer.Target

Object

Target

Enclosing interface:

Colorizer

public static class Colorizer.Target
extends Object

Information about the computed image to colorize. The most important information is the Sample­Model, as the inferred color model must be compatible with the sample model. A Target instance may also contain contextual information such as the Sample­Dimensions of the target coverage.

Constructor Summary

Constructors

Constructor	Description
Target(Sample­Model model, Rendered­Image template)	Creates a new target with the same sample dimensions and visible band as the given image.
Target(Sample­Model model, List<Sample­Dimension> ranges, int visible­Band)	Creates a new target with the sample model of the image to colorize.

Modifier and Type	Method	Description
Optional<List<Sample­Dimension>>	get­Ranges()	Returns a description of the bands of the image to colorize.
Sample­Model	get­Sample­Model()	Returns the sample model of the computed image to colorize.
Optional­Int	get­Visible­Band()	Returns the band to colorize if the colorization algorithm uses only one band.

Constructor Details

Target

public Target(SampleModel model,
 List<SampleDimension> ranges,
 int visibleBand)

Creates a new target with the sample model of the image to colorize.

Parameters:

model - sample model of the computed image to colorize (mandatory).

ranges - description of the bands of the computed image to colorize, or null if none.

visible­Band - the band to colorize if the colorization algorithm uses only one band, or -1 if none.

Target

public Target(SampleModel model,
 RenderedImage template)

Creates a new target with the same sample dimensions and visible band as the given image. This is a convenience constructor for operations producing the same kind of data than an existing image, taken as a template. The list of sample dimensions is fetched from the image property associated to the "org.apache.sis.SampleDimensions" key.

Parameters:

model - sample model of the computed image to colorize (mandatory).

template - the image from which to get the sample dimensions and visible band, or null if none.

1.5

Method Details

getSampleModel

public SampleModel getSampleModel()

Returns the sample model of the computed image to colorize. The color model created by Colorizer.apply(Target) must be compatible with this sample model.

Returns:

computed image sample model (never null).

• Color­Model.is­Compatible­Sample­Model(Sample­Model)

getRanges

public Optional<List<SampleDimension>> getRanges()

Returns a description of the bands of the image to colorize. This information may be present if the image operation is invoked by a Grid­Coverage­Processor operation, or if the source image contains the "org.apache.sis.SampleDimensions" property Note that in the latter case, the list may contain null elements if this information is missing in some bands.

Returns:

description of the bands of the image to colorize.

See Also:

• Grid­Coverage.get­Sample­Dimensions()

getVisibleBand

public OptionalInt getVisibleBand()

Returns the band to colorize if the colorization algorithm uses only one band. The value is always positive and less than the number of bands of the sample model. This information is ignored if the colorization uses many bands (e.g. Colorizer.ARGB).

Returns:

the band to colorize if the colorization algorithm uses only one band.
