Operation Property

property. Otherwise, the rotation angle is determined by the Angle result of the
AngleObject. The rotation is counter-clockwise for positive angles.

18 - FlipHoriz

Flips the image from left to right.

19 - FlipVert

Flips the image from top to bottom.

20 - FlipBoth

Flips the image horizontally and vertically.

Remarks

The Operation settings can be grouped as follows:

Morphology

Open, Close, Erode, Dilate

The morphological operations use grayscale morphology. The Polarity property determines which shade
to operate on: Dark or Light. For example, if you have dark objects on a light background, then you should
set the Polarity property to DarkOnLight. If you were to set Polarity to LightOnDark for the same image,
then executing Erode will look like a Dilate, because the light objects will be eroded, making the dark
objects dilated. The Iterations property determines how many times to execute the operation.

Convolution

Smooth, Sharpen1, Sharpen2, HorizEdge, VertEdge, EdgeDetect1 EdgeDetect2, LaPlaceEdge1,
LaPlaceEdge2, Thin, Thicken

The Polarity property determines which shade to operate on for the Thin and Thicken operations. The
Iterations property determines how many times to execute the operation.

Image Manipulation

Rotate, FlipHoriz, FlipVert, FlipBoth

Binarize

ThresholdLow and ThresholdHigh are the boundaries for determining which gray values will be black and
which values will be white. All gray values in between the thresholds will be black and all others will be
white.
