public PdfQuadrilateral(
params PdfPoint[] corners
)
VB
Public Sub New (
ParamArray corners As PdfPoint()
)
Parameters
- corners
- Type: BitMiracle.Docotic.Pdf.PdfPoint[]
Four points representing vertices of valid quadrilateral.
Remarks
Order of points is important:
-
The same set of corners can define different concave quadrilaterals. Consider this quadrilateral:
(10, 30), (30, 30), (10, 10) and (11, 12). You can simply reorder corners to define different quadrilateral:
(10, 30), (10, 10), (11, 12) and (30, 30).
-
Quadrilaterals are used for text markup annotations (descendants of PdfTextMarkupAnnotation).
First and second corners of a quadrilateral define the orientation of the annotation.
