## Tool capabilities

| Property | Value |
| --- | --- |
| Tool ID | `word-art-generator` |
| Category | design-tools |
| Implementation | Registered implementation. Registration alone is not a production-quality guarantee. |

### Implementation notes

SVG export uses your system sans-serif font. Check wrapping and font appearance in the destination.

### Inputs and settings

Text input: Your text.

Example or placeholder shown in the interface (not a validated fixture):

```text
Type or paste your input…
```

Up to 1,000,000 characters. Review the settings before running.

| Setting | Meaning | Control type | Default | Constraints |
| --- | --- | --- | --- | --- |

            }
          }
        }
      }
    }
  }
}
```

#### Error and retry handling

Failures return a non-200 status and `error.code` plus `error.message`. Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.

### Browser-agent workflow

1. Open the human page in a browser that supports WebMCP.
2. Discover the interface exposed by that page; use its actual schema.
3. Select files on the page first when the tool requires files.
4. Call `run_current_tool` with valid input and settings.
5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.

Calls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.

### Planning specification

Create styled or stacked display text with font, fill, outline, spacing and layout controls; preview PNG and SVG export with font licensing and portable rendering handled; keep word-cloud frequency visualization distinct.

This describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.

## How to use Word art generator

1. Enter your text in the input field.
2. Review the settings, then choose Run Word art generator.
3. Review the result, then use Copy result or a download link when available.

## Working with word art generator

Design utilities help translate colors, dimensions and layout values into reusable settings. A color representation or size calculation is only useful when its units and intended display context are clear.

## Common questions

### Are colors identical on every display?

No. Display calibration, color management and viewing conditions can change appearance. Numeric color conversion does not control those conditions.

### Does a computed contrast ratio describe the whole design?

A ratio compares specified foreground and background colors. Transparency, images, font size and other visual choices can change the actual reading experience.
