Constructor Details

ByteAccessor

public ByteAccessor(ByteProcessor ip,
 OutOfBoundsStrategy obs,
 InterpolationMethod ipm)

Constructor. See also the factory method ScalarAccessor.create(ImageProcessor, OutOfBoundsStrategy, InterpolationMethod).

Parameters:

ip - an instance of ByteProcessor

obs - the out-of-bounds strategy to be used (use null for default settings)

ipm - the interpolation method to be used (use null for default settings)

Method Details

getVal

public float getVal(int u,
 int v)

Description copied from class: ScalarAccessor

Reads and returns the scalar pixel value for the given image position. The value returned for coordinates outside the image boundaries depends on the OutOfBoundsStrategy specified for this ImageAccessor.

Specified by:

getVal in class ScalarAccessor

Parameters:

u - the x-coordinate

v - the y-coordinate

Returns:

the pixel value (float)

setVal

public void setVal(int u,
 int v,
 float val)

Description copied from class: ScalarAccessor

Writes a scalar pixel value to the given image position. An exception is thrown if u, v coordinates are outside the image.

Specified by:

setVal in class ScalarAccessor

Parameters:

u - the x-coordinate

v - the y-coordinate

val - the new pixel value (float)
