Photo/Bitmap Transparency

This area of the dialog is only available when the rectangle is associated with a photo or bitmap.  It permits the activation of image transparency and the selection of the transparency color.

The result of transparency is that that the badge visual contents behind the rectangle in question will show through wherever the chosen color appears.  This allows bitmaps to be created which appear to float on the card and can have an irregular shape.  For example, look at this badge with a floating shape over the photograph.
