Provides rotate coordinate behaviour for the page geometry workflow. Use it when the surrounding API family needs explicit control over PDF objects, page content, resources, conformance, or diagnostics
Declaration
procedure RotateCoordinate(X, Y, angle: Extended; var XR, YR: Extended);Unit

Parameters
| Name | Purpose |
|---|---|
X | Page coordinate or size value expressed in the current HotPDF coordinate space |
Y | Page coordinate or size value expressed in the current HotPDF coordinate space |
angle | Input used by RotateCoordinate |
XR | Input used by RotateCoordinate |
YR | Input used by RotateCoordinate |

Usage notes
- Use this API in the page geometry workflow before the affected page, resource, field, or catalog object is finalised
- Keep object names, field names, resource names, and returned handles stable until the document is finalised
- Page-level changes affect subsequent operators on the same page; save and restore graphics state when a temporary setting should not leak
