#### Live View Controls

This topic discusses the controls located at the bottom of the Live View tab.

Live View Freeze: This “pauses” the update of the live view display. This is useful if you want to keep something on the screen to analyze or take a screen capture, but you want measurement to continue in the background. To restart the Live View update, release this button.

Move to Previous Target: This moves the FOV to the previous target in a list of targets.

Skip Backwards on Target: This moves the FOV part way backwards along a target towards the previous target. This helps you see how an entire feature might be measured, even though the feature does not fit inside the FOV.

Skip Forwards on Target: This moves the FOV part way forwards along a target towards the next target. This helps you see how an entire feature might be measured, even though the feature does not fit inside the FOV.

Move to Next Target: This moves the FOV to the next target in a list of targets.

Snap to Edge Toggle: This causes selected points for feature creation to snap to the closest point along the nearest edge. If not selected, points will remain where they are clicked. See "Setting up the Live View" for more information on this feature.

Snap to Edge is also used at execution time for Manual Targets. If this option is on and you drag and drop a manual target, PC-DMIS will do an edge detection to snap the cross hair to the edge.

AutoShutter Toggle: This enables AutoShutter capability to measure features. See "Setting up the Live View" for more information on this feature.

Compass Toggle: This causes the AutoCompass to display an arrow and the distance to move for the next target. See "Setting up the Live View" for more information on this feature.

Show Target Toggle: This toggles the display of targets in the Graphics Display or Live View windows. This is the same functionality as the show target button on the Auto Feature dialog box. This is particularly useful when you are using the Quick Start window and the Auto Feature dialog box is not open.

Lock Target Toggle: This toggles the lock state of the display of targets in the Graphics Display or Live View windows. If this is locked, you cannot click and drag the target to a new location on the Live View tab.

Show Gray Scale Toggle: This toggles a gray scale depiction of the Live View tab. This button only appears when a color camera is used. For black-and-white or monochrome cameras, this icon will not appear.

Transparency: When selected, this displays a slider underneath it. You can drag the slider to set the transparency of the overlays displayed within the live view. The transparency dynamically updates as you drag the slider. This is the only place that you can change the overlay transparency. The default value is 50%. 0% = fully transparent / invisible. 100% = solid.

Magnification: When selected, this displays a slider underneath it. You can drag the slider to set the magnification of the live view without having to use Magnification tab on the Probe Toolbox. The magnification dynamically updates as you drag the slider. See "Probe Toolbox: Magnification tab" for more information on magnification.

Gage Overlay: This toggles the display of the currently selected gage overlay. Selecting the black down arrow will display the Gage Selector toolbar underneath the button, enabling you to select a different gage type to be displayed. See the "Probe Toolbox: Gages tab" for more information on gages.

Auto Void: This performs a void detection for the currently edited feature automatically adding targets with zero point density at the detected void areas.

SensiFocus: .. This executes an automatic "sensible focus" on the center of the Live View tab.

- On a DCC machine, it automatically moves the stage and then returns it to the focus position. The parameters used for this focus do not come from Focus tab of the Probe Toolbox. Instead, they are based on available data such as pixel size, depth of focus, frame rate, and so on. The focus target size is fixed and located in the center of the Live View tab.

- On a manual machine, this button is disabled.

SensiLight: This performs an on-the-spot automatic "sensible lighting" adjustment in an attempt to achieve optimal results. The Illumination tab will quickly be selected as this automatic adjustment is made. For additional information on how SensiLight this is used as a parameter for edge features, see the SensiLight description under "Automatic Hit Target - Edge Parameter Set".

[Top/Bottom/Aux] Light: Any of these buttons, when selected, displays a slider underneath the button. You can drag the slider to define the illumination intensity of that lamp without having to use the Illumination tab on the Probe Toolbox. The Illumination dynamically updates as you drag the slider. See "Probe Toolbox: Illumination tab" for more information on illumination.

Ring Lamp Overlay: This button functions a little differently from the Top Light, Bottom Light, and Aux Light buttons above. It toggles the display of the Ring Lamp Overlay on the Live View tab. To display the slider, you need to click the black down arrow. See "Probe Toolbox: Illumination tab" for more information on illumination.

Laser Toggle: This toggles the laser on and off. This is available for systems with laser probe or laser pointer fitted (e.g. TESA VISIO 300 and 500).
