Left Toolbar > Value Nodes > Compute Gradient node
The Compute Gradient node computes the rate of change of the input image in x and y and returns two images.
input
image
output
output_x
output_y
On the left toolbar choose Value Nodes > Compute Gradient. >
Drag the Compute Gradient icon into the Node Graph.
Connect an image output into the image input in the Compute Gradient node.
Adjust the attributes of the node.
image An image of VALUE color mode.
Note. If the input image is not of VALUE color mode, it is converted to value color mode using the default settings.
gradient_x An image of VALUE color mode with the rate of change in x.
gradient_y An image of VALUE color mode with the rate of change in y.
Seamless If checked, the gradientx and gradienty images will be seamless if tiled. For best results the input image should be seamless.
