# 画笔

***

## 何时使用

使用画笔为 AI 模型提供局部视觉引导。在画布上绘制形状，按颜色区分指令，并直接在画布上明确意图。

***

## 使用方法

画笔工具可与以下任务结合使用：AI 模型生成或组合。

{% stepper %}
{% step %}

#### 选择“画笔”工具

在场景下方，选择 <i class="fa-paintbrush" style="color:$primary;">:paintbrush:</i> <kbd><mark style="color:$primary;">**画笔**<mark style="color:$primary;"></kbd> 从工具菜单中选择。
{% endstep %}

{% step %}

#### 在场景上绘制

直接在画布上绘制形状，以标示需要更改的区域。
{% endstep %}

{% step %}

#### **调整画笔大小：**

在画笔子菜单中：

* 滑动大小指示器以调整画笔粗细。
* 手动输入数值。
* 将鼠标悬停在显示的数字上以选择数值。
  {% endstep %}

{% step %}

#### 更改画笔颜色

所选的每种颜色都会创建单独的图层。使用不同颜色来区分指令。

在画笔子菜单中：

1. 选择子菜单左侧的颜色圆圈。
2. 从调色板中选择
3. 使用以下方式选择颜色： <i class="fa-eye-dropper" style="color:$primary;">:eye-dropper:</i> 取色器工具
4. 在文本输入字段中输入 HEX 颜色值
   {% endstep %}

{% step %}

#### 使用橡皮擦工具

要删除已绘制的区域：

* 选择 <i class="fa-eraser" style="color:$primary;">:eraser:</i> <kbd><mark style="color:$primary;">**橡皮擦**<mark style="color:$primary;"></kbd> 在画笔工具旁边的工具菜单中选择。
* 根据需要擦除绘图的任意部分。
* 只会擦除已绘制的画笔笔触。
  {% endstep %}

{% step %}

#### 在提示词中引用画笔图层

使用画笔图层的颜色或形状来明确 AI 应如何解读特定区域。

在右侧的“生成设置”面板中：

1. 直接在文本提示字段中输入。
2. 引用你绘制的颜色或形状来传达意图。
   {% endstep %}
   {% endstepper %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.theseaai.com/main/ch/gong-ju/hua-bi.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
