Overview

This node implements a "绘图" (Drawing) operation under the resource "智谱清言". It is designed to generate images based on textual prompts. Users provide a description or prompt of what they want to visualize, and the node processes this input to produce corresponding images.

Common scenarios where this node would be beneficial include:

• Creating concept art or illustrations from text descriptions.
• Generating visual content for storytelling or presentations.
• Rapid prototyping of design ideas by describing them in natural language.

For example, a user might input the prompt "一只可爱的猫吃恐龙" ("a cute cat eating a dinosaur") to generate an imaginative image matching that description.

Properties

Name	Meaning
模型 (assistantId)	The model or intelligent agent used for generating the image. Can be any string; if unknown, it can be left blank.
提示 (prompt)	The textual prompt describing the desired image content. For example: "一只可爱的猫吃恐龙". This is a multiline string input.
语音列表 (voice)	A selection of voice options, required when using text-to-speech features (not applicable for the 绘图 operation). Options include official voices and cloned voices.

Note: The "语音列表" property is shown only when text-to-speech is enabled and is hidden for the 绘图 operation.

Output

The node outputs JSON data representing the generated image(s) based on the provided prompt. The exact structure of the output JSON is not detailed in the source code, but typically it would include fields such as:

• Image URLs or base64-encoded image data.
• Metadata about the generation process (e.g., model used, prompt text).

There is no indication that the node outputs binary data directly.

Dependencies

• The node relies on an external routing mechanism (router) imported from ./actions/router to handle the execution logic.
• It uses a version description module (versionDescription) for metadata.
• No explicit external API keys or credentials are mentioned in the provided code snippet for the 绘图 operation.
• The voice list retrieval depends on a method ttsListSearch which returns predefined voice options, but this is unrelated to the 绘图 operation.

Troubleshooting

• Empty or invalid prompt: If the prompt is empty or nonsensical, the generated image may be irrelevant or the node might fail. Ensure the prompt clearly describes the desired image.
• Model selection issues: Since the model field can be arbitrary, specifying an unsupported or incorrect model might cause errors or unexpected results.
• Missing dependencies: If the router or version description modules are not properly included or configured, the node will not execute correctly.
• Voice list errors: Although unrelated to 绘图, enabling TTS without proper configuration could cause errors in other operations.

Common error messages might relate to missing prompt input or failure in the routing call. To resolve these, verify inputs and ensure all dependencies are correctly installed and accessible.
