3.6.5 Image Capture
In this section, we will cover how to capture images within the IDV.
  1. If you have nothing displayed, then load in the bundle that we previously created.
    • Select the File→Open menu item. In the File Dialog choose workshop.xidv from your home directory.
  2. Select the View→Capture→Image... menu item from the map view's menu bar. The File Dialog will popup.
  3. The IDV requires that the window you are capturing an image in is not obscured. Move any other windows out of the way.
  4. You can save an image as a jpg, gif or png. Make sure you are in the directory /home/idv. Enter the name workshop.jpg. Click Save.
  5. Let's capture the full window. From the File Dialog enter fullwindow.png and select the Full Window button on the left.
  6. The IDV treats image files as yet another data source. Load in the newly created images by:
    • Open the Data Choosers. Show popup
    • Go to the Files tab.
    • Make sure you are in your home directory.
    • Select workshop.jpg and wholewindow.png with a control-click
  7. Since images are not geo-located we can only display the image in the Omni Control. Create this display.
  8. Now, let's save this image as a Google Earth kmz file.
    • When we capture an image for Google Earth we have to make sure we are using a Lat/Lon projection in an overhead view.
    • The easiest way to do that is to select the Projections→Use Displayed Area menu.
    • Select the View→Capture→Image menu item and enter workshop.kmz.
    • A reminder is shown about the Lat/Lon projection.
    • From a terminal window bring up Google Earth and Open this kmz file.
  9. The IDV can also read in Google Earth kml/kmz files.
    • From the IDV Data Source Chooser select the workshop.kmz file.
    • From the field selector create an Image display.
