Inserting the Teller Number XML File

We will simulate a number informing a queuing customer what teller to use. In a real world senario the XML file would typically be dynamically updated at regular intervals. For the purposes of this tutorial we will be using a static file.

Create a text file object by clicking the  icon on the overlay toolbar. Right click on the XML file object and select ‘Select File’. Browse to the ‘Overlays - Friendly Bank’ folder (C:\Program Files\Isenzo Mediacaster\Samples\Overlays - Friendly Bank). Select and open the XML file ‘Queue.xml’.

 

 

As you can see in the reference image the teller number is white and has a transparent background. We can set the active color in the color block in the left hand top corner but clicking on it.

 

 

This brings up the Windows color palette.

 

 

Choose white and then click ‘OK’. The active color in the color block changes to white. You can lock this color by checking the ‘Lock’ checkbox. Right click on your XML File Object and select ‘Use Color’. This tells the Overlay Designer to use the color in the active color box. To make the text background in the XML File object transparent, right click on the object and select ‘Use Transparent Background’.

 

 

Once you make a Text object’s background transparent, an ‘Antialias’ option appears on the property grid. Select ‘Yes’ on the Antialias dropdown.

 

Change the text size by right clicking the object and selecting ‘Font’. A Windows font properties dialogue is opened. Use this to alter the text font, size and emphasis.

 

 

In the property grid of the XML Object:

1.  Name the object in the ‘(Name)’ field. This will make it easier to manage many objects in the layers box in the top right hand corner.

2.  Enter the XML field you wish to display. The teller number is display in the following field in the sample XML file:
‘Queue.ServiceQueue.ServiceNumber’

3.  Change the ‘Antialias’ dropdown to ‘Yes’.

4.  Change the ‘Update Interval’ to 1. This would ensure regular updates of the data in a real world senario and assumes the XML file would be updated at regular short intervals.
