Screenshot of Sequence tab.

The Sequence tab allows users to setup a sequence and play through the animated results, and is available for any SAR, solid, or surface sensor that displays field results in the geometry window. For example, the image shows the sequence controls for a time-domain sensor with frames at specific, discrete points in time. The tab's input data consists of Increment, Minimum, and Maximum settings that limit the range of the sequence. The availability of these settings is determined by the result's data type.

For discrete data, The Minimum and Maximum values determine the sequence's beginning and ending frames, respectively.


XF also supports continuous data with an Increment value that cycles through the phase associated with the steady-state data from 0 to 360 degrees, as shown in the Minimum and Maximum display below the editable field.

Regardless of the data type, the Showing field displays the current frame's number, and its arrow buttons and slide bar scroll through the sequence to change its current frame selection. This value is within the minimum and maximum input range, and the Increment field controls the degrees by which it is increased or decreased using its up and down arrows, when applicable.

Move through a sequence using the following buttons:

Sequence tab additional settings. Checking the Compute Bounds option prompts XF to compute the bounds of the scale bar before playing the sequence. When this option is de-selected, users can choose when to perform this computation by manually clicking the Sequence Compute Bounds button. button. With either method, XF pauses for seconds or minutes while it uses the input data to create minimum and maximum scale bar values with a color range that helps distinguish features in the geometry window.

The Sequence Movie button. button opens the Export Movie window with options for creating a movie using the currently defined sequence. Pressing the Sequence Pause button. button cancels movie creation that is already underway. Users can find additional information about creating a movie in the following section.

The Sequence Edit Feature icon. button provides two additional settings. When checked, the Auto-Repeat Sequence option replays the sequence continuously. The Step size field displays the number of frames skipped while playing the current sequence. For example, a value of one shows every index and a value of two shows every other index.

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 values entered in the export window. 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.

The window also includes the following settings:

Clicking the Sequence Pause button. button in the Sequence tab cancels movie creation that is already underway.
