Inspection Tools

7–60

The image tool edit panel (named “

Toolset 1.Tool 3 Edit

” in Figure 7.50)

contains several data fields and buttons. These are described briefly as
follows:

Operation –– This field selects the type of operation that the image tool
is to perform: image transformation, convolution, or arithmetic
operations. The default operation is

Transform

.

Shape –– This field selects the image tool shape: rectangle, arc ring,
quad, or perspective. The default shape is

Rectangle

.

Fast Unwrap –– This box is active only when the

Transform

operation

is selected using the

Arc Ring

shape. When enabled, the “unwrap”

function operates faster, but requires 1208 bytes more memory.

Kernel –– This field is active only when the

Convolve

operation is

selected. It selects the “kernel” type and configuration to be used in the
neighborhood operation. The default kernel is

Sobel X

.

Template –– This field is active only when an image arithmetic operation
using an

S1 – T

or

S1 + T

function is selected. The

Template

field

accesses the

Image Manager

panel, from which a portion of the current

image can be stored and selected (or a previously stored image selected)
as the secondary image source,

T

(the “template”), to be subtracted from

or added to the primary image source,

S1

.

Direction –– This field is active only when an image arithmetic operation
is selected. It enables selecting a scan direction for the secondary image
(

S2

,

S1’

, or

T

) that differs from the scan direction of the primary image

(

S1

).

LUT –– This field selects a look–up table (LUT), which remaps the gray
scale values of the image pixels following a transform, convolution, or
image arithmetic operation. The default LUT is

Identity

, which has no

effect on the pixels.

Morph Passes –– The field selects the number of times the image is
passed through the morphology processors.

*P&P AOI 1 –– The

button activates the pick and place

function for AOI#1 (Area Of Interest #1), which is the primary area
within the source image (

S1

) that is “of interest” for the inspection

operation.

*P&P AOI 2 –– The

button activates the pick and place

function for AOI#2 (Area Of Interest #2), which is the secondary area
within the source image (

S2

or

S1’

) that is “of interest” for the inspection

operation. (This button in not active for

S1 – T

or

S1 + T

operations.)

P&P Dest –– The

button activates the “destination” pick and

place function. This button is active only for

Transform

operations using

the arc ring, quad, or perspective shape, which send the processed image
to a separate destination window. (For

Convolve

and image arithmetic

operations, a “destination buffer,” such as

P1

, must be specified in the

toolset edit panel.)
