- Derived classes:
- Container, Form, Group, Image, Path, PostScript, Shading, Text, TextRun
Detailed Description
The base class for elements of the content of a page. An element is a building block; everything in a PDF file is an element. An element object can be associated with a large amount of unmanaged memory in APDFL and should be deleted when the object is no longer in use.
Member Function Documentation
DisposeChildren
voidDisposeChildren()Returns:
void[static initializer]
static void[static initializer]()clone
Elementclone()Returns:
The 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
Elementclone(java.util.EnumSet< ElementCloneFlags >cloneFlags)Parameters
cloneFlags: java.util.EnumSet< ElementCloneFlags >Flags that modify the cloning operation.
Returns:
The 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 voiddelete(Booleandisposing)Parameters
disposing: Boolean
Returns:
synchronized voiddelete
synchronized voiddelete()Returns:
synchronized voidfinalize
voidfinalize()Returns:
voidgetBoundingBox
RectgetBoundingBox()Returns:
The 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
ClipgetClip()Returns:
- The current Clip for this Element.Gets the current Clip for an Element.
getMatrix
MatrixgetMatrix()Returns:
MatrixThe transformation matrix for the element.
rotate
voidrotate(doubletheta)Parameters
theta: double
Returns:
voidRotate an element by T degrees counterclockwise units using the matrix [ cos T sin T -sin T cos T 0 0 ].
scale
voidscale(doublesx, doublesy)Parameters
sx: doublesy: double
Returns:
voidScale an element by (sx,sy) units using the matrix [ sx 0 0 sy 0 0 ].
setClip
voidsetClip(Clipclip)Parameters
clip: ClipThe clip to set as the current clip for this element.
Returns:
voidSets the current Clip for an Element.
setMatrix
voidsetMatrix(Matrixmatrix)Parameters
matrix: Matrixthe transformation matrix for the element.
Returns:
voidSet the transformation matrix for the element.
translate
voidtranslate(doubletx, doublety)Parameters
tx: doublety: double
Returns:
