- 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.

Member Function Documentation
clone
Element clone()Returns:
ElementThe copied element.
Makes a copy of the element.
Make a copy of an element to obtain a new element that has a distinct set of attributes.
Note: TextRun objects may not be cloned.
clone
Element clone(java.util.EnumSet< ElementCloneFlags > cloneFlags)Parameters
cloneFlags: java.util.EnumSet< ElementCloneFlags >Flags that modify the cloning operation.
Returns:
ElementThe copied element.
Makes a copy of the element.
Make a copy of an element to obtain a new element that has a distinct set of attributes.
Note: TextRun objects may not be cloned.
delete
synchronized void delete(Boolean disposing)Parameters
disposing: Boolean
Returns:
synchronized voiddelete
synchronized void delete()Returns:
synchronized voidfinalize
void finalize()Returns:
voidgetBoundingBox
Rect getBoundingBox()Returns:
RectThe bounding box for this element. The coordinates of the bounding box are specified in user space coordinates, relative to the element's Content. Note that user space coordinates correspond to unrotated pages; any rotation specified in the page dictionary is not taken into account.
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.
getClip
Clip getClip()Returns:
ClipThe current Clip for this Element, or NULL if no clip is set.
Gets the current Clip for an Element.
getColorSpace
ColorSpace getColorSpace()Returns:
ColorSpaceThe ColorSpace associated with this Shading, obtained from the shading dictionary.
Get the ColorSpace of the current Shading object.
getGraphicState
GraphicState getGraphicState()Returns:
GraphicStateThe GraphicState for this Shading, or NULL if none is set.
Get the graphic state of the current Shading object. May return null if this element does not have a GraphicState.
getMatrix
Matrix getMatrix()Returns:
MatrixThe current transformation matrix applied to this element.
The transformation matrix for the element.
rotate
void rotate(double theta)Parameters
theta: doubleThe rotation angle in degrees.
Returns:
voidRotate an element by theta degrees counterclockwise using the matrix [ cos T sin T -sin T cos T 0 0 ].
scale
void scale(double sx, double sy)Parameters
sx: doubleThe horizontal scale factor.
sy: doubleThe vertical scale factor.
Returns:
voidScale an element by (sx,sy) units using the matrix [ sx 0 0 sy 0 0 ].
setClip
void setClip(Clip clip)Parameters
clip: ClipThe clip to set as the current clip for this element, or NULL to remove clipping.
Returns:
voidSets the current Clip for an Element.
setMatrix
void setMatrix(Matrix matrix)Parameters
matrix: MatrixThe transformation matrix for the element.
Returns:
voidSet the transformation matrix for the element.
translate
void translate(double tx, double ty)Parameters
tx: doubleThe horizontal translation distance in user space units.
ty: doubleThe vertical translation distance in user space units.
Returns:
voidTranslate an element by (tx,ty) units using the matrix [ 1 0 0 1 tx ty ].
