Rotate a region around its center. 以区域中心为旋转中心顺时针旋转当前ROI区域。 The region is rotated clockwise by the specified angle. 区域按指定角度顺时针旋转。 Note: Rotated LRectRegion or LMaskRegion objects may become larger than the original, because the bounding rectangle of rotated vertices determines the result region. 注...
AI agents use il_region_rotate to create or update resources in Leaper Vision Toolkit — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Leaper Vision Toolkit environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
da | number | — | 旋转角度 (double类型) |
regionClassObjDescriptionJson | string | — | 原始的Roi区域。传入一个序列化的JSON字符串，属性包括：LpvClassName(调用工具函数的名称) 和 InputParameterFile(调用工具函数需要传入的参数文件名称)。这两个属性的值可以从前处理的MCP工具的返回值中获取。LpvClassName 表示要调用的Region接口名称，根据不同的区域类型 |
Parameters from the server's own tool schema.
This tool creates or modifies image data (a rotated region) in a reversible manner. The rotation is a transformation that can be undone by rotating in the opposite direction, and the output is a new region object rather than destructively altering the original.
From the tool's definition Tool performs image region rotation: 'Rotate a region around its center', 'The region is rotated clockwise by the specified angle', 'outputs a new ROI region object'. The operation modifies image data by transforming spatial coordinates of a region.
Attacks that exploit this kind of access
Rotate a region around its center. 以区域中心为旋转中心顺时针旋转当前ROI区域。 The region is rotated clockwise by the specified angle. 区域按指定角度顺时针旋转。 Note: Rotated LRectRegion or LMaskRegion objects may become larger than the original, because the bounding rectangle of rotated vertices determines the result region. 注意：旋转后的 LRectRegion 或 LMaskRegion 对象可能比原始区域更大，因为旋转后的顶点的包围矩形组成了结果区域范围。 并输出一个新的ROI区域对象(ILRegion类型)的描述JSON。 其中输出的ROI区域类型与输入区域相同. It is categorised as a Write tool in the Leaper Vision Toolkit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
il_region_rotate accepts 2 parameters: da, regionClassObjDescriptionJson. The full parameter table on this page comes from the server's own tool schema.
Register the Leaper Vision Toolkit MCP server in PolicyLayer and add a rule for il_region_rotate: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Leaper Vision Toolkit. Nothing to install.
il_region_rotate is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the il_region_rotate rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for il_region_rotate. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
il_region_rotate is provided by the Leaper Vision Toolkit MCP server (leaper-mcp/leaper-mcp-proxy). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
