Method Summary

Modifier and Type	Method	Description
ScalarAccessor	getComponentAccessor(int k)	Returns the ImageAccessor for the k-th component; the result is a sub-type of ScalarAccessor.
int	getDepth()	Returns the depth (number of components) of this image accessor.
float	getVal(double x, double y, int k)	Returns the interpolated value of the pixel's k-th component at the specified position.
float	getVal(int u, int v, int k)	Returns the value of the pixel's k-th component at the specified position.
void	setVal(int u, int v, int k, float val)	Sets the value of the pixel's k-th component at the specified position.

Method Details

getDepth

public int getDepth()

Description copied from class: ImageAccessor

Returns the depth (number of components) of this image accessor. 1 is returned if the image is scalar-valued.

Specified by:

getDepth in class ImageAccessor

Returns:

the image depth.

getComponentAccessor

public ScalarAccessor getComponentAccessor(int k)

Description copied from class: ImageAccessor

Returns the ImageAccessor for the k-th component; the result is a sub-type of ScalarAccessor. In the case of a scalar-valued image, THIS object is returned.

Specified by:

getComponentAccessor in class ImageAccessor

Parameters:

k - the component index

Returns:

the component accessor.

getVal

public float getVal(int u,
 int v,
 int k)

Description copied from class: ImageAccessor

Returns the value of the pixel's k-th component at the specified position. If the associated image is scalar-valued, this is equivalent to component 0. See also ImageAccessor.getDepth().

Specified by:

getVal in class ImageAccessor

Parameters:

u - the x-coordinate

v - the y-coordinate

k - the component index

Returns:

the component value (float)

getVal

public float getVal(double x,
 double y,
 int k)

Description copied from class: ImageAccessor

Returns the interpolated value of the pixel's k-th component at the specified position. If the associated image is scalar-valued, this is equivalent to component 0. See also ImageAccessor.getDepth().

Specified by:

getVal in class ImageAccessor

Parameters:

x - the x-coordinate

y - the y-coordinate

k - the component index

Returns:

the interpolated component value (float[])

setVal

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

Description copied from class: ImageAccessor

Sets the value of the pixel's k-th component at the specified position. If the associated image is scalar-valued, this is equivalent to component 0. See also ImageAccessor.getDepth().

Specified by:

setVal in class ImageAccessor

Parameters:

u - the x-coordinate

v - the y-coordinate

k - the component index

val - the new component value
