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)
