Description
Compare recorded brush-stroke width with a supplied reference width.
Artwork dimensions depend on whether a measurement describes the image, support, window, overlap or reserved edge. Linear enlargement multiplies area by the square and volume by the cube of the scale. A signed clearance or width adjustment retains useful direction information, while a nominal geometric fit still needs material, production and installation context.
Compare recorded brush-stroke width with a supplied reference width.
When to use this tool
Use Brush Mark Stroke Width Ratio when you already have recordedStrokeWidth, suppliedReferenceWidth and need to compare recorded brush-stroke width with a supplied reference width.
How to use the tool and how it works
- Enter recordedStrokeWidth, suppliedReferenceWidth. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read widthRatio. Use the output convention below.
Require recordedStrokeWidth>=0 and suppliedReferenceWidth>0; return stroke/reference.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| recordedStrokeWidth | Recorded Stroke Width | Required. Finite number; minimum 0. |
| suppliedReferenceWidth | Supplied Reference Width | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| widthRatio | Width Ratio | Required. Finite number. |

}Limitations and assumptions
- Widths need matching units; the ratio does not identify a brush, material or artistic technique.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check an actual dimensioned layout or calibrated test piece for mounting and production. Use a geometric model for full enlargement or overlap accounting, and physical drawdowns or material tests when thickness behavior matters.
