The sequence tab is available for any SAR, solid, or surface sensor that displays field results in the geometry window. The controls within this tab allow users to setup the sequence and play through the animated results. The image above shows the controls for a time-domain sensor with frames at specific, discrete points in time.

The Minimum and Maximum values entered here determine the beginning and ending frames of the sequence. The Showing value displays the frame currently being viewed, and the up/down arrows or scroll bar can change that selection to any frame within the sequence.

Move through the sequence using the following buttons:

Screenshot. Checking the Compute Bounds option prompts XF to automatically compute the bounds of the scale bar before playing the sequence. Alternatively, clicking the icon manually selects the same option. Regardless of how the option is selected, it may cause XF to pause for seconds or minutes as it reads all the data points in the sequence looking for minimum and maximum field values.

The button opens a dialog for creating a movie of the currently defined sequence. Once movie creation is underway, it can be cancelled by pressing . Additional information can be found below.

Screenshot. Additional settings can be adjusted by clicking the icon. Checking the Auto-Repeat Sequence box automatically replays the sequence continuously. Step size skips frames while playing the sequence, so a value of 1 shows every index, a value of 2 shows every other index, and so on.

Export a Movie

In order to create a movie, XF first stores a screenshot of each frame (based on the Minimum, Maximum, and Step size) in a temporary file. It then combines the frames into the final animation based on the user defined framerate and duration. This process is more sophisticated than taking a standard screenshot and it enables users to create movies through a remote desktop, when the XF program is minimized, or when XF is covered by another application.

This window also includes the following settings:

Clicking the button in the Sequence tab will cancel the movie creation.
