Enclosing class:

TLcdComponentColorLookupTable

public static class TLcdComponentColorLookupTable.Builder<B extends TLcdComponentColorLookupTable.Builder<B>>
extends Object

Builder for component-based color lookup table's. The default table's are 2 pixels wide with 8-bit color components and use linear interpolation. The actual filter must be specified as either a ColorFilter or pixel buffers.

For example to create a negative filter:

   TLcdComponentColorLookupTable table = TLcdComponentColorLookupTable.newBuilder().
     filter(
       new ILcdColorFilter() {
         public void apply( float[] aRGBColorSFCT ) {
           aRGBColorSFCT[ 0 ] = 1.f - aRGBColorSFCT[ 0 ];
           aRGBColorSFCT[ 1 ] = 1.f - aRGBColorSFCT[ 1 ];
           aRGBColorSFCT[ 2 ] = 1.f - aRGBColorSFCT[ 2 ];
         }
       }
     ).
     build();

Method Detail

size

public B size(int aSize)

Sets the size of all table's.

Parameters:

aSize - the size of the table's

Returns:

this builder

size

public B size(int aRedSize,
              int aGreenSize,
              int aBlueSize)

Sets the size of each component's table.

Parameters:

aRedSize - the size for the red color component

aGreenSize - the size for the green color component

aBlueSize - the size for the blue color component

Returns:

this builder

componentType

public B componentType(TLcdLookupTable.ComponentType aComponentType)

Sets the type of the table's color components.

Typically a byte provides sufficient accuracy for rendering.

Parameters:

aComponentType - the component type

Returns:

this builder

interpolation

public B interpolation(ELcdInterpolationType aInterpolationType)

Sets the interpolation type between table pixels. Note that only NONE and LINEAR are currently supported.

Parameters:

aInterpolationType - the interpolation type

Returns:

this builder

filter

public B filter(ILcdColorFilter aColorFilter)

Sets the table's entries from a color filter.

Parameters:

aColorFilter - the color filter

Returns:

this builder

filter

public B filter(Buffer aPixelData)

Sets the each component table's entries directly from a buffer.

The buffers should contain the appropriate number of bytes according to the table table size and component type. Each table entry has 1 component. See TLcdComponentColorLookupTable and TLcdLookupTable for details.

Parameters:

aPixelData - the pixel buffer

Returns:

this builder

filter

public B filter(Buffer aRedPixelData,
                Buffer aGreenPixelData,
                Buffer aBluePixelData)

Sets the component table's entries directly from a buffer.

The buffers should contain the appropriate number of bytes according to the table table size and component type. Each table entry has 1 component. See TLcdComponentColorLookupTable and TLcdLookupTable for details.

Parameters:

aRedPixelData - the pixel buffer

aGreenPixelData - the pixel buffer

aBluePixelData - the pixel buffer

Returns:

this builder

build

public TLcdComponentColorLookupTable build()

Builds the color lookup table.

Returns:

the color lookup table
