Symmetry

Overview

Mirror-copies half, or one quarter, of an image to the opposite side. Drawing only half for a symmetric result literally halves the work on front-facing characters, icons, emblems, and UI frames.

Usage tips

• The go-to pairing is draw only half in pixel_canvas → complete it here. Redrawing also affects only the half.
• Quad, four-way symmetry, is powerful for emblems, ornamental frames, and floor-tile decoration. Draw at one-quarter density and it naturally becomes a complete pattern.
• Perfect symmetry can look artificial. After mirroring, add asymmetric eyes, scars, or decorations with blend to give the image life.

Common pitfalls

• The center column looks thick: at odd width, the center column remains unchanged. For a clean central axis, draw on the axis at an odd size, or design a 2px axis at an even size.
• Only a flip is needed: use flip_h in transform to reverse the entire image. This node sacrifices one half to build symmetry.

Technical details

• At odd dimensions, the center column or row remains unchanged.
• Quad mirrors the upper-left quarter into the other three quadrants. It suits decorative patterns and UI frames.

Examples

1. Front-facing character: half-drawn Pixel Canvas → Symmetry(左半分を右へ) for the full body
2. Check asymmetry: compare before/after with Blend(Difference) to make asymmetric areas light up
3. Emblem or frame: create four-way decoration from one-quarter of a pattern with Quad
