Description
Take maximum left/top and minimum right/bottom, clamp disjoint terminal bounds to the chosen left/top, and return nonnegative dimensions and a strictly positive hasArea flag.
A layout divides finite space among content, margins, gutters, and clearances. Counts describe how many gaps exist, while offsets and snapping describe where edges fall; changing either convention changes the resulting dimensions.
Take maximum left/top and minimum right/bottom, clamp disjoint terminal bounds to the chosen left/top, and return nonnegative dimensions and a strictly positive hasArea flag.
When to use this tool
Use Clipping Mask Visible Bounds Term when you need a local layout dimension or alignment check with explicit geometric inputs.
How to use the tool and how it works
- Enter left, top, right, bottom, maskLeft, maskTop, maskRight, maskBottom. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read left, top, right, bottom, width, height, hasArea. Inspect hasArea before interpreting the associated values.

}Limitations and assumptions
- Touching rectangles have no area, and disjoint coordinates are collapsed placeholders; this handles axis-aligned boxes rather than actual clipping paths, curves, or pixel visibility.
- 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
Construct the full layout in a design application and inspect its bounds. For overlapping or rotated content, use geometric intersection and containment rather than independent one-dimensional allowances.
