Pick and Place Function
5–29
A light probe (one is assigned to each camera) can be picked and placed
anywhere within the top half of the image field; however, its size and shape
can be changed only within certain limits: The smallest size is 8 pixels long
by 8 pixels high, and the largest size is 32 pixels long by 64 pixels high
(these sizes will vary with different camera resolution settings).
The button in the Probe panel activates the light probe for
repositioning and resizing; that is, after picking that button you can pick the
light probe in one of its four corners to change its size, or you can pick it in
the center to move it without changing its size.
When you pick the button, the light probe changes color from red to
green, indicating that it is enabled for “pick and place” operations. At the
same time, the
Pick & Place panel appears on the screen, as shown in
Figure 5.27.
Figure 5.27 Example: Pick and Place Panel for a Light Probe
The Pick & Place panel for the light probe contains the following data
display fields and buttons:
•
X Loc –– This indicates the current X coordinate, in pixels, of the
upper–left corner of the probe box from the left side of the screen.
•
Y Loc –– This indicates the current Y coordinate, in pixels, of the
upper–left corner of the probe box from the top of the screen.
•
Length –– This indicates the current length of the probe box, in pixels.
•
Height –– This indicates the current height of the probe box, in pixels.
•
Arrow buttons,
↑, ↓, ←, and → –– When you pick an arrow button, by
default the entire light probe moves one pixel in the direction of the
corresponding arrow. If, however, you have just picked and placed one
corner of the light probe, the arrow buttons will affect that part of the light
probe only.
•
Done –– When you finish the pick and place operations, picking the
button returns to the camera setup panel.
