No-Letter Rule Violation Checker
Screen independently witnessed independentlyObservedLetterCountagainst a no-letter/no-seal design preference, not automatic image recognition or flag invalidity.
Description
A no-lettering preference concerns whether independently identified letters occur in a design.
A no-lettering preference concerns whether independently identified letters occur in a design.1
This tool converts your observed letter count into a presence flag.
When to use No-Letter Rule Violation Checker
Use this tool when you need to reproduce the stated calculation from measured records or independently selected model inputs. Establish the flag dimensions, orientation, specification, palette, or visual annotations needed for this particular calculation.
How to use No-Letter Rule Violation Checker and understand its results
- Establish the flag dimensions, orientation, specification, palette, or visual annotations needed for this particular calculation.
- Enter independentlyObservedLetterCount, following the field table and rules below, then run the tool.
- Read result. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| independentlyObservedLetterCount | Independently observed letter count | number | Required |
Enter an integer letter count from zero to ten thousand. Return true exactly when the count is greater than zero; no image analysis or flag validity judgment occurs.
hasObservedLetters=(count>0) Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or reference | object |
| result.hasObservedLetters | Has Observed Letters | boolean |

}Limitations and assumptions
The calculation uses supplied geometry, observations, or annotations. It does not establish an official construction specification, national identity, or universal design quality.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related review, use Writing-on-Flag Design Detector: Writing on a flag is a visual feature that must first be identified and located within the field. This checker records whether those two annotations support the fixed writing-pattern candidate. For a complementary step, use NAVA Good Flag Principle Scorer: NAVA’s five design principles provide a framework for human flag review. This calculator combines independently judged scores with your weights and explicitly records the weight of unassessed principles.
