The
            Bilinear Ramp tool lets you create images with a variety of properties
            and in several formats. The Bilinear Ramp tool is comprised of five
            sets of color channel value fields that let you to generate a multi-color
            image based on RGBA values. One set of values is for generating
            the fill color, and four sets are for generating start and end ramped
            colors residing in a four-quadrant region of definition (ROD). The
            fill color is defined as those pixels residing outside the ROD.
            Two other controls let you to position the X and Y axes of the ramps
            at any location in the image.
         
         NoteThe following procedure
               assumes that you have a Schematic view and a Player view open.
            
         To create a bilinear ramped image:
         
         
            - Drag the Bilinear Ramp tool from the
               Tools tab to the dependency graph in the Schematic view and attach
               it to the Output node.
            
- Apply image properties—see 
                        Setting Image Generation Properties and Formats.
            
- Adjust the color values in the Fill,
               Lower Left, Lower Right, Upper Left, and Upper Right.
            
- Modify the location and direction of
               the X and Y ramps.
               NoteYou can also manipulate
                     the linear ramp by clicking and dragging the horizontal and vertical
                     bars.
                   
NoteYou can also type
               values directly into the value fields and press Enter.
