Function trimMaskRectBounds

trimMaskRectBounds<T extends NullableMaskRect>(target: T, bounds: Rect): void
Intersects a target rectangle with a boundary, trimming dimensions and masks in-place. This utility calculates the axis-aligned intersection between the target and bounds. If the target includes a mask (as in a NullableMaskRect), the mask is physically cropped and re-aligned using extractMaskBuffer to match the new dimensions.
Type Parameters
- T extends NullableMaskRect
Parameters
- target: T
  The rectangle or selection object to be trimmed. Note: This object is mutated in-place.
- bounds: Rect
  The boundary rectangle defining the maximum allowable area (e.g., canvas dimensions).
Returns void
Example
```
const selection = { x: -10, y: -10, w: 50, h: 50, mask: new Uint8Array(2500) };
const canvas = { x: 0, y: 0, w: 100, h: 100 };
// Selection will be moved to (0,0) and resized to 40x40.
// The mask is cropped by 10 px on the top and left.
trimRectBounds(selection, canvas);
```
