Graphical Display controls provide several different ways to display images within a graphical panel:
Static Image Display: Choose a single image to display within the panel (an example is shown in Figure 1).
Dynamic Image Display: Select multiple images, each of which has an Index Number property that references it. You can then change which image is shown by linking a signal to a control, so the image displayed changes as the signal value does. This feature can also be used to create animations.
Group Box: Create a graphical box to contain other panel controls.
The special properties for the Graphical Display control can be found in Table 1. A list of common properties can be found under Common Control Properties.
Table 1: Graphical Display Control Properties
| Property | Function and Options |
|---|---|
Images | Launches a special dialog box that allows you to select one or more images to show within this control; an example of the interface can be found in Figure 2. Use the + button to add an image to the control; after doing so, VSpy will show a preview of the image, along with its name, width, height, and an integer Index Number that you can use to select the image by linking it to a signal. Press the - button to remove an image previously selected. Note: The image displayed by default is the one with an Index Number value of 0. If no image has that index, the Graphical Display control will appear blank until the signal linked with the control is set to a value matching one of the actual Index Number values in the image set. |
Stretch | Specifies whether an image should be shown at its standard size, or stretched to fit the Graphical Display control:

TransparentColor | Double-click to select a color in the image to be shown as transparent. |
