Thumbnail image
-
Under [Graphical Views] there is a Component called "Thumbnail Image". If this is placed one can select a point. The help ? does not refer to how this works or what this is. I have tried putting a base64 image in a alphanumeric virtual point, but it says data point invalid. How does this work?

Hi glamprecht,
This component is supposed to have "Image" type data points supplying it values. The only image data source is the HTTP Image, which retrieves an image from a given URL every poll. You can bind this data point to that component, raise the scale factor from 0 to whatever looks nice, and you'll see the images being pulled in from the HTTP Image data source.

Thank you. If the images does not have to be recorded in the database, I guess it is easier to just put a HTTP component down that point to the image?

The Image is sort of in the database. The HTTP Image source will save your images into Mango/web/WEB-INF/filedata/ and save file information into the database as a string. You certainly can use an HTML component to load a remote image for your graphical view, as well.
