Pitney Bowes MapInfo Professional - Manual (Page 413)

The OGC WMS specification supports transparent pixel definition for image formats. This allows you to
use the images you retrieve as overlays and not solely as the bottom layer of your map.
To set the background to transparent, click the Transparent check box in the Open WMS Table or the
WMS Table Properties dialog boxes. You can also control the transparency and translucency of the
image via Layer Control (by double-clicking the layer and checking the Style Override check box on
the Layer Display tab in the Layer Properties dialog box).
