In rendering modes Arrow, Background and Streamline you have the possibility to define a transfer function wich is used for mapping the data value to color and associated opacity values.
It is also possible to load or save a transfer function in these modes by using the buttons Load... and Save...
Additionally the minimum and maximum values of the selected property are displayed.

• By clicking with the left mouse button into the area of the transfer function you create a point at this position
• By using the "drag & drop" method you can change the position of the the point. Simply click on a point, hold the mouse button pressed and then move the mouse. When you release the button again the point is set at the new location.
• Double clicking onto a point opens a window where you can define its color.
• Clicking with the right mouse button onto a point removes it from the transfer function and its neighbour points are connected with each other.
