A color representation or size calculation is only useful when its units and intended display context are clear.\nCommon questions\nAre colors identical on every display?\nNo. Display calibration, color management and viewing conditions can change appearance. Numeric color conversion does not control those conditions.\nDoes a computed contrast ratio describe the whole design?\nA ratio compares specified foreground and background colors. Transparency, images, font size and other visual choices can change the actual reading experience.\nContinue your workflow:\nCurved text generator\n,\nText to image\n,\nColor picker\n.",

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.\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nCreate 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.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"word-art-generator\",\n  \"category\": \"design-tools\",\n  \"built\": true,\n  \"requirements\": \"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.\",\n  \"implementation\": {\n    \"fields\": [\n      {\n        \"key\": \"size\",\n        \"label\": \"Font size\",\n        \"value\": 48,\n        \"type\": \"number\"\n      },\n      {\n        \"key\": \"width\",\n        \"label\": \"Canvas width\",\n        \"value\": 800,\n        \"type\": \"number\"\n      },\n      {\n        \"key\": \"height\",\n        \"label\": \"Canvas height\",\n        \"value\": 300,\n        \"type\": \"number\"\n      },\n      {\n        \"key\": \"color\",\n        \"label\": \"Text\",\n        \"value\": \"#171717\",\n        \"type\": \"color\"\n      },\n      {\n        \"key\": \"background\",\n        \"label\": \"Background\",\n        \"value\": \"#ffffff\",\n        \"type\": \"color\"\n      },\n      {\n        \"key\": \"outline\",\n        \"label\": \"Outline\",\n        \"value\": \"#171717\",\n        \"type\": \"color\"\n      }\n    ],\n    \"note\": \"SVG export uses your system sans-serif font.

Review the settings, then choose Run Word art generator.\n3. Review the result, then use Copy result or a download link when available.\n\n## Working with word art generator\n\nDesign 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.\n\n## Common questions\n\n### Are colors identical on every display?\n\nNo. Display calibration, color management and viewing conditions can change appearance. Numeric color conversion does not control those conditions.\n\n### Does a computed contrast ratio describe the whole design?\n\nA ratio compares specified foreground and background colors. Transparency, images, font size and other visual choices can change the actual reading experience.\n\nContinue your workflow: [Curved text generator](https://happytails.ai/en/design-tools/curved-text-generator/), [Text to image](https://happytails.ai/en/text-tools/text-to-image/), [Color picker](https://happytails.ai/en/design-tools/color-picker/).\n"
