resizeLassoRect - Supernote

You must create a lasso selection before calling this API; otherwise the call fails.

static resizeLassoRect(
  rect: Rect,
  rotationDegree?: number
): Promise<APIResponse<boolean>>;

Parameters

Parameter	Type	Description
`rect`	`Rect`	Lasso rectangle (pixel coordinates)
`rotationDegree`	`number`	Optional rotation angle in degrees, as an integer. Omit it to keep the current rotation; when provided, supported elements in the current lasso selection rotate by this angle

Notes

rotationDegree applies only to strokes, geometries, and five-pointed stars; other element types are not rotated
In lasso data, elements with text boxes do not support stretch resizing, such as title text boxes and link-related text elements, including text links and links set through text boxes; all other element types support stretch resizing
Omit rotationDegree when rotation is not needed

Returns

APIResponse<boolean>: result === true indicates the resize succeeded

Example

import { PluginCommAPI, type Rect } from 'sn-plugin-lib';

/**
 * Example: resize the lasso rectangle and optionally rotate supported elements.
 */
export async function exampleResizeLassoRect(rotationDegree?: number) {
 const current = await PluginCommAPI.getLassoRect();
 if (!current.success) {
 throw new Error(current.error?.message ?? 'getLassoRect call failed');
 }

 const rect = current.result as Rect;
 const w = rect.right - rect.left;
 const h = rect.bottom - rect.top;
 const cx = rect.left + w / 2;
 const cy = rect.top + h / 2;
 const scale = 1.2;
 const nextRect: Rect = {
 left: cx - (w * scale) / 2,
 top: cy - (h * scale) / 2,
 right: cx + (w * scale) / 2,
 bottom: cy + (h * scale) / 2,
 };

 console.log('resizeLassoRect nextRect:', nextRect, 'rotationDegree:', rotationDegree);
 const res = await PluginCommAPI.resizeLassoRect(nextRect, rotationDegree);
 if (!res.success) {
 throw new Error(res.error?.message ?? 'resizeLassoRect call failed');
 }
 console.log('resizeLassoRect result:', res.result);
 return res.result;
}
