THPDFPageDisplayList.CropBox Property

Exposes the portion of the page that is actually seen: the /CropBox clipped against the /MediaBox, captured whilst the display list is compiled

Declaration

property CropBox: THPDFRectangle read FCropBox;

Unit

HPDFPageRenderer

Usage notes

• Where a /CropBox is absent, or fails to overlap the /MediaBox, the /MediaBox itself is used; the rectangle is normalised so that Left < Right and Bottom < Top
• Renderers arrive at the output size and the device transform from this box together with the page /Rotate value, so content lying outside it is left undrawn
• Compiled paint-object bounds remain in page space and are not clipped against this box; MediaBox holds the /MediaBox itself
