Using Labels - XVCapture/DCV

Labels allow you to create a layer of text and markings over top of an image. 

Labels are only viewable when in the image enhancement view.

Begin by making your image full screen. You can do so by double clicking the image. Once in full screen mode, you should see 'Labels' at the top.

Undo/Redo are available for use with labels.

Interact with Labels

After creating a label, your mouse will likely still be ready to create more labels. Clicking this option changes your mouse back to a cursor that allows you to manipulate the labels you have placed down.

Double click any placed layer to see additional options.

• 'Freeze Label' will prevent the movement of that particular label.
• 'Dynamic Edges' will automatically adjust the layers edges to most closely fit the layer.

Pen

The Pen tool allows you to use your mouse and left click on the image to draw on the image.

Measure

Only use this tool if your sensor is calibrated. See this article on calibrating sensor measurements to calibrate. You can check if the sensor that captured your image is calibrated by clicking the 'calibrations' tab at the bottom of the screen.

Single-click on the left mouse button; move the cross-hair to the end-point of the object; and then double-click on the left mouse button.

Non-linear calibrations can be created by left-clicking on mid-points while moving the mouse from point to point. Double-click on the left mouse button at the final end-point.
