快速入门

基本概念

程序

程序（亦可称为"脚本"）是用户编写的运行逻辑。

新建程序只需点击程序列表面板的"+"按钮，打开新建程序对话框，填写程序名称与描述后点击"确认"即可完成：

以上即为创建的第一个程序。按快捷键F5或点击按钮即可运行该程序。

程序由节点构成，每个节点包含"输入端"（亦称"输入连接器"）和"输出端"（亦称"输出连接器"）。节点之间通过连接输入端与输出端来确定数据传输方向及执行顺序：

选项

选项是程序的输入或输出参数。

点击选项面板中的"+"按钮，打开新建选项对话框，配置用途、类型和名称，最后点击"确认"按钮即可完成创建：

可以将选项直接拖入画布中使用：

执行器

执行器可为程序配置不同的选项值，以处理不同的任务。多个执行器可并行运行（需订阅增强版）。

新建执行器的操作如下图所示：

数据类型

基础

整数：64位有符号整数，可表示的整数范围为： $[- 2^{63}, 2^{63} - 1]$ 。
浮点数：双精度浮点数。
布尔：包含两个可能的值，即真(True)或假(False)，专门用于执行逻辑判断和控制程序的运行流程。
字符串：用于表示文本的数据类型。

复合

二维整数向量
二维浮点数向量
四维整数向量
四维浮点数向量

JSON

JSON值：可以表示除原生类型外的其它所有类型，具体类型运行时可通过数据/JSON/值类型节点判断。
JSON对象：无序的键值对集合，其中键是字符串类型。
JSON数组：有序的JSON值集合。

原生

图像
ONNX
文本识别引擎
视频流

选项类型

选项是程序的输入/输出，每种数据类型都有对应的选项类型；此外，针对具体使用场景，我们额外增加了一些选项类型，它们是：

基于整数的：

键盘按键选择器
鼠标按钮选择器
窗口句柄选择器
显示器句柄选择器
颜色拾取器
日期时间选择器

基于字符串的：

路径选择器
图像路径选择器

节点执行顺序

INFO

复制图片下方的 JSON 代码至程序画布，即可快速测试节点效果。

每个程序只有一个控制流/程序结束节点，可通过画布右上角的按钮快速定位。
除控制流/分支节点和控制流/循环类节点外，其余节点均按从左到右、从上到下的顺序依次执行。
