Method Detail

setImage

public void setImage(ImageFloat32 image)

Description copied from interface: InterpolatePixel

Change the image that is being interpolated.

Parameters:

image - An image.

get_fast

public float get_fast(float x,
             float y)

Description copied from interface: InterpolatePixelS

Returns the interpolated pixel value at the specified location while assuming it is inside the image far away from the border. For any input point InterpolatePixel.isInFastBounds(float, float) should return true.

Parameters:

x - Point's x-coordinate.

y - Point's y-coordinate.

Returns:

Interpolated intensity value.

get

public float get(float x,
        float y)

Description copied from interface: InterpolatePixelS

Returns the interpolated pixel value at the specified location while taking in account the image border. Bounds checking is done to ensure that the coordinate is inside the image and to see if the interpolation technique needs to be adjusted for the image border.

Parameters:

x - Point's x-coordinate. x >= 0 && x < image.width

y - Point's y-coordinate. y >= 0 && y < image.height

Returns:

Interpolated intensity value or NaN if it can't be interpolated.

getImageType

public ImageType<ImageFloat32> getImageType()

Description copied from interface: InterpolatePixel

Type of image it can process
