Description
Return panel join-width total and share.
Artwork measurements distinguish physical dimensions, projected regions and scale conventions. Length, area and volume change with different powers of a scale, while frame overlaps and crop geometry depend on which boundaries were measured. A numerical fit does not identify an artwork or establish its historical interpretation.
Return panel join-width total and share.
When to use this tool
Use Painted Panel Join Width Fraction when checking the stated artwork dimension, crop, frame or scale relation.
How to use the tool and how it works
- Enter joinWidths, panelWidth. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read totalJoinWidth, fraction. Use the output convention below.
Return panel join-width total and share. Require panelWidth > 0, nonnegative joinWidths and their sum <= width; fraction = sum/panelWidth.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| joinWidths | Join Widths | Required. Array of finite number; maximum items 256. |
| panelWidth | Panel Width | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| totalJoinWidth | Total Join Width | Required. Finite number. |
| fraction | Dimensionless ratio using the denominator specified above; not a percentage unless explicitly stated. | Required. Finite number. |

}Limitations and assumptions
- Join overlap must already be handled by the supplied widths; actual construction, structural condition and provenance are not inferred.
- 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
Inspect the original object, measured boundaries and appropriate complete geometry or catalog record for physical or historical conclusions.
