Emboss

Node icon
Filter

Creates a raised relief effect by highlighting edges based on a simulated light direction.

Emboss simulates a light source hitting a raised surface, creating highlights on one side of edges and shadows on the other. The angle controls the light direction (135° = classic top-left), and the size controls how far the relief extends.

In Alpha mode, the emboss uses the silhouette shape instead of the color detail, which is useful for creating beveled buttons or badge effects from flat icons.

SourceChoice
Default: Color

Edge source

  • ColorCreates relief from the image's color/detail — embosses texture and content.
  • AlphaCreates relief from the silhouette shape — produces a beveled button/badge effect.
Angle degreesNumber
Default: 135.0 Range: 0–360

Light source direction; 135=top-left classic emboss

SizeNumber · px/%
Default: 1.0 Range: 0.5–200.0

Highlight/shadow spread; small=sharp, large=soft bevel

StrengthNumber
Default: 1.0 Range: 0–5.0

Relief intensity; 0=none, higher=more pronounced

Mask

Mask FitChoice
Default: None

Mask sizing

  • NoneCenter the mask at its native size — no resizing. Unmasked regions are unaffected.
  • StretchStretch the mask to exactly match the image dimensions. May distort the mask shape.
  • FitScale the mask to fit inside the image, preserving aspect ratio. Letterboxes where needed.
  • FillScale the mask to fill the image, preserving aspect ratio. Crops edges if aspect ratios differ.
Notes

Mask Fit only visible when mask is connected.

Pins: image (required), mask (optional). When mask is connected, the effect is blended with the original using the mask (white = full effect, black = original).

Usage Tips

Section titled “Usage Tips”
  • Alpha mode creates a bevel effect from any silhouette, making it great for UI icons.
  • Combine with Composite (Overlay mode) to emboss on top of the original image.
  • Use a small size (1–3) for subtle texture enhancement.
  • Connect a mask input to apply the emboss effect to only part of the image.
