PdfQuadrilateral Class |
This class represents a four-sided polygon. It is typically used in marking text on the page.
For drawing order purposes, if the quadrilateral is a rectangle on the page, P0 is the lower-left
corner, P1 is the lower-right corner, P2 is the upper right corner, and P3 is the upper-left corner.
Misordering the points may result in the shape being rendered upside down or as a bow-tie.

Properties| Name | Description | |
|---|---|---|
  | Empty |
Gets an empty quadrilateral.
|
| Item |
Gets or sets the PdfPoint at the specified index. Index may be
0-3 inclusive.
|
| P0 |
Gets or sets the Point 0.
|
| P1 |
Gets or sets the Point 1.
|
| P2 |
Gets or sets the Point 2.
|
| P3 |
Gets or sets the Point 3.
|
Methods| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsConcave |
Determines whether this quadrilateral is concave. A quadrilateral is concave if it is
simple and if it is not convex.
|
| IsConvex |
Determines whether this quadrilateral is convex. A quadrilateral is convex if it is
not empty and if its diagonals cross.
|
| IsEmpty |
Determines whether this quadrilateral is empty.
|
| IsRectangular |
Determines whether this quadrilateral is rectangular. Note that this test checks to
see if the diagonals are equal and the shape is convex, therefore it is correct regardless of rotation.
|
| IsSimple |
Determines whether this quadrilateral is convex. A quadrilateral is simple if it is
not empty and if its edges do not cross.
|
| LowerBound |
Gets the lower bound of the quadrilateral.
|
| LowerBound(PdfPoint) |
Gets the smaller of the LowerBound and the supplied point.
|
| MaxX |
Gets the maximum of all X coordinates.
|
| MaxY |
Gets the maximum of all Y coordinates.
|
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| MinX |
Gets the minimum of all X coordinates.
|
| MinY |
Gets the minimum of all Y coordinates.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| UpperBound |
Gets the upper bound of the quadrilateral.
|
| UpperBound(PdfPoint) |
Gets the larger of the UpperBound and the supplied point.
