Method Summary

Modifier and Type	Method	Description
static RgbAccessor	create(ColorProcessor ip, OutOfBoundsStrategy obs, InterpolationMethod ipm)
float[]	getPix(double x, double y)	Returns the interpolated pixel value for the specified floating-point position as a float[] with either 1 element for scalar-valued images and or more elements (e.g., 3 for for RGB images).
float[]	getPix(int u, int v)	Returns the pixel value for the specified floating-point position as a float[] with either 1 element for scalar-valued images and or more elements (e.g., 3 for for RGB images).
ColorProcessor	getProcessor()	Returns the source ImageProcessor associated with this ImageAccessor.
void	setPix(int u, int v, float[] valf)	Sets the pixel value at the specified integer position.

Constructor Details

RgbAccessor

public RgbAccessor(ColorProcessor ip,
 OutOfBoundsStrategy obs,
 InterpolationMethod ipm)

Constructor.

Parameters:

ip - the associated image

obs - the out-of-bounds strategy to be used

ipm - the interpolation method to be used

Method Details

create

public static RgbAccessor create(ColorProcessor ip,
 OutOfBoundsStrategy obs,
 InterpolationMethod ipm)

getPix

public float[] getPix(int u,
 int v)

Description copied from class: ImageAccessor

Returns the pixel value for the specified floating-point position as a float[] with either 1 element for scalar-valued images and or more elements (e.g., 3 for for RGB images).

Specified by:

getPix in class ImageAccessor

Parameters:

u - the x-coordinate

v - the y-coordinate

Returns:

the pixel value (float[])

getPix

public float[] getPix(double x,
 double y)

Description copied from class: ImageAccessor

Returns the interpolated pixel value for the specified floating-point position as a float[] with either 1 element for scalar-valued images and or more elements (e.g., 3 for for RGB images). Interpolation is used non-integer coordinates.

Specified by:

getPix in class ImageAccessor

Parameters:

x - the x-coordinate

y - the y-coordinate

Returns:

the interpolated pixel value (float[])

setPix

public void setPix(int u,
 int v,
 float[] valf)

Description copied from class: ImageAccessor

Sets the pixel value at the specified integer position. The new value must be provided as float[] with 1 element for scalar-valued images or 3 elements for RGB images.

Specified by:

setPix in class ImageAccessor

Parameters:

u - the x-coordinate

v - the y-coordinate

valf - the new pixel value (float[])

getProcessor

public ColorProcessor getProcessor()

Description copied from class: ImageAccessor

Returns the source ImageProcessor associated with this ImageAccessor.

Overrides:

getProcessor in class ImageAccessor

Returns:

the image processor
