Constructor Detail

public SliderState()

SliderState() - constructor

Method Detail

init

public void init(Flicker flicker,
                 java.lang.String name)

init() - set state to default values.

Parameters:

flicker - is instance of Flicker

name - of the SliderState

reset

private void reset()

reset() - reset state to default values.

clone

public SliderState clone(SliderState src)

clone() - clone a copy of the src SliderState

Parameters:

src - SliderState to clone

Returns:

the cloned SliderState instance

copy

private boolean copy(SliderState src,
                     SliderState dst)

copy() - copy src SliderState to dst SliderState

Parameters:

src - SliderState to copy

dst - SliderState that we copy to

Returns:

true if succeed

readState

public void readState(java.lang.String iName)

readState() - Read scroller state from .flk startup state file.

Parameters:

iName - of the image to read (e.g., "I1", or "I2")

writeState

public void writeState(java.lang.String iName,
                       java.lang.StringBuffer sBuf)

writeState() - Write this scroller state to string buffer sBuf

Parameters:

iName - of the image to read (e.g., "I1", or "I2")

sBuf - is the string buffer to write to.

getStateStr

public java.lang.String getStateStr(ImageData iData,
                                    java.lang.String fileName)

getStateStr() - get this scroller state as a string

Parameters:

iData - is the image data to use

fileName - associated with the iData

Returns:

state string

cvtZoomMagScr2Str

public static java.lang.String cvtZoomMagScr2Str(int zmScr)

cvtZoomMagScr2Str() - convert a zoomMag scroller value to a prettyprint string with 2 digits.

Parameters:

zmScr - is zoomMag scroller value to convert to 2 digit mag string

Returns:

converted string

cvtZoomMagScr2ZoomMagVal

public static float cvtZoomMagScr2ZoomMagVal(int zmScr)

cvtZoomMagScr2ZoomMagVal() - convert a zoomMag scroller value to a zoom mag value. Compute this by mapping the scroller range [MIN_ZOOM_MAG : MAX_ZOOM_MAG] to the value range [MIN_ZOOM_MAG_VAL : MAX_ZOOM_MAG_VAL] by solving the linear equation and then interpolating the value.

Parameters:

zmScr - is the zoomMag integer scroller value in the range of [MIN_ZOOM_MAG : MAX_ZOOM_MAG] to convert

Returns:

converted value in the magnification domain
