The URL is the address of the image to be retrieved. Use the icon to test
the URL. (Opens in a new window or browser tab.) The Timeout and Retry fields determine how long to
wait for the web server to return the image, and how many times to retry the connection in the event of failures. If
all of the retries are exhausted, a data point exception event is raised.
Images can be automatically scaled as required to save memory or file system space. (Images can be scaled up as well, but since this does not increase resolution it is usually not practical to do.) The "percent" scaling type is a "relative" scaling method that results in an image that is scaled to the Scale percentage size of the original image. The "box" scaling method is an "absolute" scaling method that scales the original image so that it fits into the "box" defined by the given Scale width and Scale height.
The read limit allows the setting of a maximum response size that may be received. If the size of the image data exceeds the given value the data will be discarded and a data retrieval event will be raised.
If the image source is a web cam, you may enter live feed code into the provided text area. This code will be entered verbatim into a new window or browser tab (surrounded by html and body tags). If the web cam live feed requires the use of an ActiveX component or Java applet you will need to install such components appropriately within the Mango instance.
