构造器详细资料

TransitionFilter

public TransitionFilter(BufferedImageOp filter,
                        String property,
                        float minValue,
                        float maxValue)

Construct a TransitionFilter.

参数:

filter - the filter to use

property - the filter property which is changed over the transition

minValue - the start value for the filter property

maxValue - the end value for the filter property

方法详细资料

setTransition

public void setTransition(float transition)

Set the transition of the image in the range 0..1.

参数:

transition - the transition min-value 0 max-value 1

getTransition()

getTransition

public float getTransition()

Get the transition of the image.

返回:

the transition

另请参阅:

setTransition(float)

setDestination

public void setDestination(BufferedImage destination)

Set the destination image.

参数:

destination - the destination image

另请参阅:

getDestination()

getDestination

public BufferedImage getDestination()

Get the destination image.

返回:

the destination image

另请参阅:

setDestination(java.awt.image.BufferedImage)

prepareFilter

public void prepareFilter(float transition)

Prepare the filter for the transiton at a given time. The default implementation sets the given filter property, but you could override this method to make other changes.

参数:

transition - the transition time in the range 0 - 1

filter

public BufferedImage filter(BufferedImage src,
                            BufferedImage dst)

toString

public String toString()
