Constructor Detail

FlipImageTransform

public FlipImageTransform()

Calls this(null).

FlipImageTransform

public FlipImageTransform(int flipMode)

Calls this(null) and sets the flip mode.

Parameters:

flipMode - the deterministic flip mode 0 Flips around x-axis. >0 Flips around y-axis. <0 Flips around both axes.

FlipImageTransform

public FlipImageTransform(Random random)

Constructs an instance of the ImageTransform. Randomly does not flip, or flips horizontally or vertically, or both.

Parameters:

random - object to use (or null for deterministic)

Method Detail

doTransform

protected ImageWritable doTransform(ImageWritable image,
                                    Random random)

Specified by:

doTransform in class BaseImageTransform<org.bytedeco.opencv.opencv_core.Mat>

query

public float[] query(float... coordinates)

Description copied from interface: ImageTransform

Transforms the given coordinates using the parameters that were used to transform the last image.

Specified by:

query in interface ImageTransform

Overrides:

query in class BaseImageTransform<org.bytedeco.opencv.opencv_core.Mat>

Parameters:

coordinates - to transforms (x1, y1, x2, y2, ...)

Returns:

transformed coordinates
