property PageMetrics[PageNumber: Integer]: TPdfPageMetrics; // read only
| PageNumber | Integer between 1 and PageCount |
| Result | TPdfPageMetrics snapshot for the requested page with presence flags HasMediaBox, HasCropBox, HasBleedBox, HasTrimBox, and HasArtBox |
The snapshot includes Width, Height, Rotation, LabelText, HasTransparency, and all five standard page boxes
Each box has a matching presence flag so callers can distinguish an absent optional box from a zero-valued rectangle
The first request reads all facts through one native page handle and later requests reuse the cached snapshot until the document or page is edited
Reading another page does not change PageNumber or fire OnPageChange
The returned record is caller-owned and changing it does not modify the PDF
