Constructor Detail

ImageUtilPtr

public ImageUtilPtr(long cPtr,
                    boolean cMemoryOwn)

ImageUtilPtr

public ImageUtilPtr()

Default constructor yielding a NULL-pointer.

ImageUtilPtr

public ImageUtilPtr(ImageUtil ptr)

Do not take ownership of ptr.

ptr can be null.

The constructor is implicit on purpose.

Method Detail

getCPtr

public static long getCPtr(ImageUtilPtr obj)

delete

public void delete()

deref

public ImageUtil deref()

The pointer stored in the object.

__ref__

public ImageUtil __ref__()

Dereferencing operator.

getDeref

public ImageUtil getDeref()

Member access operator.

equals

public boolean equals(ImageUtil p)

isShared

public boolean isShared()

check if this Ptr has shared ownership or none
ownership

Returns:

true if Ptr has shared ownership, false if it has no ownership.

isNull

public boolean isNull()

checks if the pointer is null

Returns:

Returns true if the pointer is null

cptr

public ImageUtilCPtr cptr()

RGB2GRAY

public void RGB2GRAY(Image src,
                     Image dst)

converts an image of RGB type into an image of
GRAY type.

reset

public void reset(Image img,
                  int color)

sets the value of all channels of an image to
color.

reset

public void reset(Image img)

sets the value of all channels of an image to
color.

flipX

public void flipX(Image img)

flips the image around the x-axis (horizontal)

Parameters:

img -

flipY

public void flipY(Image img)

flips the image around the y-axis (vertical)

Parameters:

img -

makeDepthImage

public ImagePtr makeDepthImage(PointCloud cloud)

Conditional comment:

End of conditional comment.

convert pointcloud to a depth image. Colors are scaled to min and ax distance of
points.

Parameters:

cloud - [in] cloud to convert to image

Returns:

image showing the pointcloud as a depth image

makeDepthImage

public ImagePtr makeDepthImage(PointCloud cloud,
                               float min,
                               float max)

convert pointcloud to a depth image. Colors are scaled to min and max distance
specified by user

Parameters:

cloud - [in] cloud to convert to image

min - [in] the minimum distance corresponding to black

max - [in] the maximum distance corresponding to white

Returns:

image showing the pointcloud as a depth image
