Corner Pin

Node icon
Transform

Applies a perspective warp by repositioning the four corners of the image. Perfect for mockups, screen replacements, and 3D compositing.

Corner Pin lets you drag the four corners of an image to arbitrary positions, applying a perspective (homography) transform. This is the standard technique for placing flat artwork onto angled surfaces: billboards, phone screens, books, or any surface seen in perspective.

When a background image is connected, the Output Mode selector lets you composite the warped result directly onto the background. Corner positions are specified as percentages of the reference dimensions, and interactive manipulators in the preview panel make positioning intuitive.

Output

Output ModeChoice
Default: Composite

Warped Only / Composite (when background connected)

  • Warped OnlyOutput only the perspective-warped image on a transparent background.
  • CompositeComposite the warped image onto the connected background.

Filter

InterpolationChoice
Default: Bilinear

Nearest / Bilinear / Lanczos

  • NearestNo interpolation — preserves hard pixel edges. Best for pixel art.
  • BilinearSmooth blending between pixels — good general-purpose quality.
  • LanczosHighest quality with sharp detail preservation — best for final output.
Notes

Corners are interactive via the preview manipulator. Output Mode only visible when background input is connected. Reference dimensions = background size (if connected) or foreground size.

Usage Tips

Section titled “Usage Tips”
  • Use the interactive corner handles in the preview for visual placement.
  • Connect a background image and set Output Mode to Composite to place artwork directly onto a surface.
  • Corner values beyond 0–100% let you extend the warp beyond the original frame.
  • Use Lanczos interpolation for the highest quality output on final renders.
