Constructor Detail

SnakeFilter

public SnakeFilter(int layMethod)

Constructs SnakeFilter of one of the predefined lay methods, default divide factor (5) and delay between frames = 0.1 sec (10 1/100 sec)

Parameters:

layMethod - one of the predefined lay methods: LAY_METHOD_SPIRAL_FROM_CENTER, LAY_METHOD_SPIRAL_FROM_CORNER, LAY_METHOD_ZIG_ZAG, LAY_METHOD_LEFT_RIGHT_DIRECT, LAY_METHOD_LEFT_RIGHT_INVERSE

Throws:

java.lang.IllegalArgumentException - If unknown lay method

SnakeFilter

public SnakeFilter(int layMethod,
                   int divideFactor)

Constructs SnakeFilter of one of the predefined lay methods, the specified divide factor and default delay between frames = 0.1 sec (10 1/100 sec)

Parameters:

layMethod - one of the predefined lay methods: LAY_METHOD_SPIRAL_FROM_CENTER, LAY_METHOD_SPIRAL_FROM_CORNER, LAY_METHOD_ZIG_ZAG, LAY_METHOD_LEFT_RIGHT_DIRECT, LAY_METHOD_LEFT_RIGHT_INVERSE

divideFactor - number of generated tiles = squared divide factor. For example, value of 5 means 25 tiles (frames) to generate

Throws:

java.lang.IllegalArgumentException - If unknown lay method

java.lang.IllegalArgumentException - If divide factor less than 2

SnakeFilter

public SnakeFilter(int layMethod,
                   int divideFactor,
                   int delayBetweenFrames)

Constructs SnakeFilter of one of the predefined lay methods, the specified divide factor and delay between frames

Parameters:

layMethod - one of the predefined lay methods: LAY_METHOD_SPIRAL_FROM_CENTER, LAY_METHOD_SPIRAL_FROM_CORNER, LAY_METHOD_ZIG_ZAG, LAY_METHOD_LEFT_RIGHT_DIRECT, LAY_METHOD_LEFT_RIGHT_INVERSE

divideFactor - number of generated tiles = squared divide factor. For example, value of 5 means 25 generated tiles

delayBetweenFrames - delay time in 1/100 seconds (100 means 1 second delay) between generated frames.

Throws:

java.lang.IllegalArgumentException - If unknown lay method

java.lang.IllegalArgumentException - If divide factor less than 2

java.lang.IllegalArgumentException - If delay less than 1
