Shading Class Documentation
class Shading : ElementNamespace:Datalogics::PDFL
- Inherits from:
Element
Detailed Description
Represents a region shaded with color, as defined by a shading dictionary.
A shading pattern defines a gradient fill in a graphic that produces a smooth transition between colors across the area covered by the graphic area. The "sh" paint operator is invoked for the shading object. This does not correspond to a shading dictionary within a PDF pattern. Refer to the Pattern object for shading dictionaries used in PDF patterns.

Property Documentation
BoundingBox
Rect BoundingBox[get]The bounding box for this element.
The bounding box is a rectangle that is guaranteed to encompass the element, but it is not guaranteed to be the smallest box that could contain the element. For example, if the element is a Path that contains an arc, the bounding box encompasses the bezier control points, and not just the curve itself.
Clip
Clip Clip[get, set]Gets the current Clip for an Element.
ColorSpace
ColorSpace ColorSpace[get]Get the ColorSpace of the current Shading object.
GraphicState
GraphicState GraphicState[get]Get the graphic state of the current Shading object.
May return null if this element does not have a GraphicState.
Matrix
Matrix Matrix[get, set]The transformation matrix for the element.
Member Function Documentation
Clone
Element Clone()Returns:
ElementThe copied element.

Note: TextRun objects may not be cloned.
Clone
Element Clone(ElementCloneFlags cloneFlags)Parameters
cloneFlags: ElementCloneFlagsFlags that modify the cloning operation.
Returns:
