Description
Require x and y within positive imageWidth and imageHeight and divide each coordinate by its corresponding dimension.
Layout calculations relate dimensions, offsets, and normalized positions in a drawing or display. A numeric coordinate depends on its origin and scale, while a size allowance must use the same length unit as the object.
Require x and y within positive imageWidth and imageHeight and divide each coordinate by its corresponding dimension.
When to use this tool
Use Image Focal Point Normalized Coordinate when you need a stated layout component from supplied dimensions or a normalized position.
How to use the tool and how it works
- Enter x, y, imageWidth, imageHeight. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read normalizedX, normalizedY. Use the output convention below.

| Input field | Meaning and units | Accepted input |
|---|---|---|
| x | X | Required. Finite number; minimum 0. |
| y | Y | Required. Finite number; minimum 0. |
| imageWidth | Image Width | Required. Finite number; strictly above 0. |
| imageHeight | Image Height | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| normalizedX | Normalized X | Required. Finite number. |
| normalizedY | Normalized Y | Required. Finite number. |

}Limitations and assumptions
- The far boundary maps to one even for pixel-based dimensions; origin, axis direction, and pixel-center conventions must be supplied consistently.
- 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 the assembled layout at its final scale and include installation or production allowances separately.
