Warp node

Left Toolbar > Compose icon Filter Nodes > Warpicon Warp node

The Warp node applies a warp filter to the input image. The warp filter displaces the pixels in the input image to a position defined by the gradient image and the amount value.

The gradient image defines the direction of displacement

Procedure

To warp an image:

  1. On the left toolbar choose Filter Nodes > Warp. Filter icon > Warp icon

  2. Drag the warp icon into the Node Graph.

    Warp node

  3. Connect the output of an image node into the image input in the Warp node.

  4. Connect the output of an image node into the gradient input in the Warp node.
  5. Adjust the attributes of the Warp node to modify the output image.

Inputs

image
The Image to be warpped.

gradient
The image that defines the direction of displacement of the pixels.

Outputs

image The warped image.

Attributes Panel

Warp attributes

Amount
The amount of displacement.

Soften
Softens the gradient image using a blur filter.

Boundary
Defines how to handle pixels outside range of the image Seamless: Pixels are repeated from the other side of the image, generating an output image that can be tiled. Mirror: Pixels are mirrored from the same side of the image. Border: Border pixels are repeated. Zero: Out of range pixels are set to 0.0.

Iterations
Applies multiple passes of the warp filter with proportional amount values.

Mix
Blending mode of the images generated by the iteration passes. Average: The output value is the average of the iteration pass values. Maximum: The final value is the maximum of the iteration pass values. Minimum: The final value is the minimum of the iteration pass values.
