The Environmental Variable TMSSPDFLOGOPATH
defines the fully qualified path of a JPG image that is to be used when the TMSSREPORTFORMAT specifies PDF output.
The logo file, to avoid any distortion, should be 400 pixels wide by 168 pixels high.
If your logo does not fit these dimensions, use white space padding around your logo to pad it out to an appropriate format.
