Using the Linear Ramp Tool

The Linear Ramp tool lets you create images with a variety of properties and in several formats. The Linear Ramp tool is comprised of three sets of color channel value fields that allow you to generate a multi-color image based on RGBA values. One set of values is for generating the fill color, and two sets are for generating start and end ramped colors residing in the region of definition (ROD). The fill color is defined as those pixels residing outside the ROD. Two other controls allow you to position the center of the ramp at any vertical or horizontal point in the image.

NoteThe following procedure assumes that you have a Schematic and a Player view open.

To create a linear ramped image:

Drag the Linear Ramp tool from the Tools tab to the dependency graph in the Schematic and attach it to the Output node.

The Linear Ramp UI appears.
Apply image properties—see Setting Image Generation Properties and Formats.
Adjust the Fill, Start, and End color values by dragging inside the value fields.
Modify the location and direction of the linear ramp.

NoteYou can also manipulate the linear ramp by clicking and dragging the vertical bar.

NoteYou can also type values directly into the value fields and press Enter.

NoteThe Linear Ramp tool's Fill, Start, End, and Ramp Center parameters are animatable by setting keyframes or using expressions—see Setting Keys Manually and Validating and Applying the Expression String.
