Path Bounds

Overview

Extracts a path's bounding rectangle (minimum/maximum coordinates, size, and center) as numbers. It supplies information for shape-responsive wiring, such as placing or scaling something to match a path's dimensions.

Usage tips

• A typical use is centering. Use center in a transform translation calculation to center a path no matter where it was drawn.
• Derive canvas dimensions or spacing from size to build a graph whose layout follows edits to the path automatically.
• Process the values directly with math_op / expression_float. Separate Float outputs keep the wiring short.

Related nodes

• transform — align something using the bounds

• path_sample — when you need a point on the path rather than a rectangle

• fit_to_canvas — automatic fitting on the image side

• expression_float / expression_vec2 — process the bounds values

Behavior

• scope = All
  • Returns the combined bounds of all subpaths.
• scope = SubPath
  • Returns the bounds of only the specified subpath.
• Bounds are calculated from the actual curve shape, not the positions of control handles.
• An empty path or nonexistent subpath index returns 0 for every value.

Examples

Get the path width and height

[Bezier Path] → [Path Bounds] → width, height

Measure only a specified subpath

[Multi Path] → [Path Bounds(scope: SubPath, sub_path_index: 1)]

Pass the center of the bounds to another node

[Bezier Path] → [Path Bounds] → center_x, center_y → [Transform]

Notes

• min / max / size / center are Vec2 outputs.
• The same values are also available as Float outputs such as min_x, allowing direct connections to numeric nodes.
• The upper limit of the sub_path_index slider updates automatically to the number of subpaths in the input path.
• If a saved index is currently above that limit, the value is preserved and an out-of-range warning is shown. It becomes active again if the subpath count returns.
