Enclosing class:

TLcdLookupTable

public static class TLcdLookupTable.Builder
extends Object

Builder for lookup tables. The default table has a single 8-bit color component per table entry and uses linear interpolation. The dimensions of the table and actual table pixel data must be specified. You can specify the pixel data using:

• an index color model
• a color map
• directly as a buffer

For example to create a table based on a color map:

   TLcdLookupTable table = TLcdLookupTable.newBuilder().
     fromColorMap(myColorMap).
     build();

TLcdLookupTable.Builder	fromSignedIndexColorModel(IndexColorModel aIndexColorModel) Sets the table's dimensions, component count, component type and data from an index color model that is used with signed indices.
TLcdLookupTable.Builder	interpolation(ELcdInterpolationType aInterpolationType) Sets the interpolation type between table pixels.
TLcdLookupTable.Builder	mappedInterval(double aMin, double aMax) Sets the the interval of values that should be mapped on the table data.

Method Detail

dimensions

public TLcdLookupTable.Builder dimensions(int... aDimensions)

Sets the dimensions of the table.

Parameters:

aDimensions - the size of the table along each dimension, the table must have at least 1 dimension and all sizes must be greater than 0

Returns:

this builder

componentCount

public TLcdLookupTable.Builder componentCount(int aComponentCount)

Sets the number of components for a single table entry.

Parameters:

aComponentCount - the number of components for a single entry

Returns:

this builder

componentType

public TLcdLookupTable.Builder componentType(TLcdLookupTable.ComponentType aComponentType)

Sets the type of a pixel component.

Parameters:

aComponentType - the type of a component

Returns:

this builder

interpolation

public TLcdLookupTable.Builder interpolation(ELcdInterpolationType aInterpolationType)

Sets the interpolation type between table pixels.

Parameters:

aInterpolationType - the interpolation type

Returns:

this builder

data

public TLcdLookupTable.Builder data(Buffer aPixelData)

Sets the table's entries directly from a buffer.

The buffer should contain the appropriate number of bytes according to the table dimensions(int[]) dimensions}, component type and #components.

Parameters:

aPixelData - the pixel buffer

Returns:

this builder

mappedInterval

public TLcdLookupTable.Builder mappedInterval(double aMin,
                                              double aMax)

Sets the the interval of values that should be mapped on the table data.

Parameters:

aMin - the interval minimum

aMax - the interval maximum

Returns:

this builder

mappedInterval

public TLcdLookupTable.Builder mappedInterval(ILcdInterval aInterval)

Sets the the interval of values that should be mapped on the table data.

Parameters:

aInterval - the interval of values that should be mapped on the table or null if it is unknown

Returns:

this builder

fromIndexColorModel

public TLcdLookupTable.Builder fromIndexColorModel(IndexColorModel aIndexColorModel)

Sets the table's dimensions, component count, component type and data from an index color model.

After this call only the other properties, not affected by this call, should be modified.

Note that some color models are intended for signed data. In this case you should use fromSignedIndexColorModel(java.awt.image.IndexColorModel).

Parameters:

aIndexColorModel - the index color model

Returns:

this builder

fromSignedIndexColorModel

public TLcdLookupTable.Builder fromSignedIndexColorModel(IndexColorModel aIndexColorModel)

Sets the table's dimensions, component count, component type and data from an index color model that is used with signed indices.

After this call only the other properties, not affected by this call, should be modified.

This should for example be used for TLcdIndexColorModel's and the color models from a TLcdDTEDColorModelFactory.

Parameters:

aIndexColorModel - the index color model

Returns:

this builder

fromColorMap

public TLcdLookupTable.Builder fromColorMap(TLcdColorMap aColorMap)

Sets the table's dimensions, component count, component type, interpolation type, interval and data from a color map.

After this call only the interpolation and interval properties should be modified.

Parameters:

aColorMap - the color map

Returns:

this builder

build

public TLcdLookupTable build()

Builds the lookup table.

Returns:

the lookup table
