Constructor Detail

SbDiscreteLineProfile

public SbDiscreteLineProfile(SbVec3i32 p1,
                             SbVec3i32 p2,
                             SoImageDataAdapter image)

Constructor defining the profile line on the image.

Parameters:

p1 - begin point of the profile. Can be a 2d, 3d and 3d+t point.

p2 - end point of the profile. Can be a 2d, 3d and 3d+t point.

image - image to profile. Cannot be NULL. Throws an SbException if any p1 or p2 are out of image. Throws an SbException if image is NULL.

Method Detail

getValue

public double getValue(int index)

Calls getValue(index, (int)0).

getPosition

public SbVec4i32 getPosition(int index)

Returns the position along the line at specified displacement relatively to first point. Range of index is between 0 and n-1 with n, the number of voxels in the segment (see getLength), Throws an SbException if index is out of bounds.

setValue

public void setValue(SbDiscreteLineProfile copyFrom)

getFirstPosition

public SbVec4i32 getFirstPosition()

Returns the first point.

getValue

public double getValue(int index,
                       int component)

Returns the value along the line at specified displacement relatively to first point.

Parameters:

index -

component - choose the component of the voxel. Default is 0 which correspond to 1-component image. Range of index is between 0 and n-1 with n, the number of voxels in the segment (see getLength). Range of component is between 0 and c - 1 with c is the number of component of the image ( e.g c = 1 for grayscale, c = 3 for RGB, c = 4 for RGBA ). Throws an SbException if index is out of bounds.

getLength

public long getLength()

Returns the length of extracted data (i.e. the number of extracted voxels).

getValueAt

public double getValueAt(int i)

getLastPosition

public SbVec4i32 getLastPosition()

Returns the last point.
