Slide Show Tool

You can use the Slide Show Tool to observe the motion, growth, and decay of radar echoes.

The Slide Show Tool can display different products from different times (while the animation tool is limited to a linear time sequence of one product). For example, in the following figure, different 4 slides of different products are shown in the Quick Look Window (QLW) for 10 seconds.

You can configure multiple windows so that images in different windows change at the same time.

For multiple window presentations it is convenient to use Setup > Output to configure the start-up window location, window size, and legend on/off.
tip You can use Slide Show Tool for a weather briefing display for which there is no operator/observer control of the display.

  1. Select the slide show icon to display the tool.
  2. Enter the number of slides in Number of slides in show.

    This field determines the number of slides in a show (maximum 16).

    IRIS inserts the specified number of blank rows in the slide list.

    You must populate each slide with information about the product it will display.

  3. For each slide select the slide number (or row) and do the following:
    1. Specify the site, type, and product name.

      Select from products on the disk.

      If there is no product of the type that you want, for example, if it has not been made yet, select the blank product name "––––––" and type the name you want. When the product has been transferred to your disk, it is displayed in the slide show.

    2. Specify the Time Lag.

      Time Lag specifies the version of the product according to the following rules:

      • 0 The current (most recent) version of the product.
      • 1 The previous version of the product, that is, the second most recent.
      • 2 Two products prior to the current version.

      This enables the comparison of product versions. In a multi-window environment, the newest version of a CAPPI product can be displayed alongside a CAPPI product from the previous hour.

      To make a single step time sequence, type the same product type, the name for each slide, and specify 0, 1, 2, ... for the lags.
    3. Specify the Dwell Time, that is, how long the slide is displayed on the screen, before sequencing to the next slide.

      In the example menu, each slide is displayed for 10 seconds.

      Dwell Time defines how long a slide is on the screen as well as a precise clock schedule of time slots for displaying the slides, that is:

      • Slide 1 Displayed at Midnight 00:00:00
      • Slide 2 Displayed at 00:00:00 plus the Slide One Dwell Time.
      • Slide 3 Displayed at 00:00:00 plus the Slide 1 and Slide 2 Dwell Times

      The schedule increments throughout the day.

      Note that a slide show can start at any time, but the time slots are defined by the above algorithm. This allows you to configure multi-window slide shows where the images in different windows all change at the same time and in the proper sequence.

    4. Select Apply.
  4. To clear incorrect slide information, select the slide number (or row) and then Clear.
