ROI Edge Filtering Button
Similar to Raster Edge Filtering above, but the filtering is applied to the left and
right sides of the Region of Interest portion of that ROI's output. Default setting is
On.
NOTE: The Rotation, Frame Delay, and Flip controls interact with each other.
NOTE: If the ROI’s video processing circuit is unable to perform the configured
processing, the actual Off state of each control is reported in red. See "About the
Rotation, Flip, and Frame Delay Controls" on page 26 for more information.
Opens a drop down menu for selecting of a clockwise rotation setting (see Figure
17 ):
• 0° (no rotation, default setting)
• 90°
• 180°
• 270°
Frame Delay
Turns Frame Delay On or Off. One frame of delay is automatically applied
whenever Rotate or Flip is active. The current frame delay state (On or Off) is
reported.
NOTE: Turning Frame Delay On can be useful if you are using two ROIs simultaneously,
flipping or rotating only one of their outputs. Because a frame delay is always
applied to the flipped or rotated output, turning on the other ROI’s Frame Delay
restores their relative timing.
Horizontal Flip
Flips the output horizontally (left to right, and right to left).
Vertical Flip
Flips the output vertically (top to bottom and bottom to top).

About the Rotation, Flip, and Frame Delay Controls
Rotation and Flip image processing requires one frame of video delay. Whenever
a rotation or flip occurs a frame delay is automatically applied, and the Frame
Delay On status is reported, even if the checkbox isn’t selected (see Figure 18 ).
