Detailed Description

PdeElement class.

PdeElement is the base class for elements of a pagemap (PdePageMap). The general PdeElement methods allow you to get and set general element properties. PdeElement is an abstract superclass from which the PdeText, PdeTextLine, PdeWord, PdeTable, PdeImage, PdeContainer, PdeLine, PdeRect, PdeTableCell, PdeFormField, PdeHeader, PdeFooter classes are derived. Use PdeElement::GetType method to find the type of an element.

Member Function Documentation

◆ GetAlignment()

virtual PdfAlignment PdeElement::GetAlignment ( )

pure virtual

Gets the element alignment within the content column.

Returns: Requested element alignment.

◆ GetAngle()

virtual double PdeElement::GetAngle ( )

pure virtual

Gets the element angle.

Returns: Requested element angle.

◆ GetBBox()

virtual void PdeElement::GetBBox ( PdfRect * bbox )

pure virtual

Gets the bounding box for an element in user space coordinates. To avoid the device-dependent effects of specifying objects in device space, PDF defines a device-independent coordinate system that always bears the same relationship to the current page, regardless of the output device on which printing or displaying occurs. This device-independent coordinate system is called user space. The origin of the user space(0, 0) represents the bottom-left corner of the PDF page. PDF files specify 72 points to 1 physical inch. The returned bounding box is guaranteed to encompass the element.

Parameters

bbox	(Filled by the method) A pointer to a PdfRect structure specifying the bounding box of an element, specified in user space coordinates.

◆ GetChild()

virtual PdeElement* PdeElement::GetChild ( int index )

pure virtual

Gets the requested child element from an element.

Parameters

index The index of element to obtain.

Returns: Requested element.

See also: PdeElement::GetNumChildren

◆ GetData()

virtual void* PdeElement::GetData ( )

pure virtual

Gets user-supplied data to pass to the element.

Returns: User-supplied data from the element.

◆ GetFlags()

virtual int PdeElement::GetFlags ( )

pure virtual

Get the element state flags.

Returns: the element flags as PdfElementStateFlags.

◆ GetGraphicState()

virtual void PdeElement::GetGraphicState ( PdfGraphicState * g_state )

pure virtual

Gets the graphics state information for an element.

Parameters

g_state (Filled by the method) Pointer to a PdfGraphicState structure that contains graphics state information for pdeElement.

◆ GetId()

virtual int PdeElement::GetId ( )

pure virtual

Gets the id of an element. The id is unique number on a page.

Returns: Unique number for the element.

◆ GetNumChildren()

virtual int PdeElement::GetNumChildren ( )

pure virtual

Gets the number of child elements in an element object.

Returns: The number of children.

See also: PdeElement::GetChild

◆ GetNumPageObjects()

virtual int PdeElement::GetNumPageObjects ( )

pure virtual

Get the the number pf page object in the element.

Returns: The number of page objects.

◆ GetPageMap()

virtual PdePageMap* PdeElement::GetPageMap ( )

pure virtual

Get the the page map object containing this element.

Returns: The page map object.

◆ GetPageObject()

virtual PdsPageObject* PdeElement::GetPageObject ( int index )

pure virtual

Get the the page object of the element by index.

Returns: The page object.

◆ GetType()

virtual PdfElementType PdeElement::GetType ( )

pure virtual

Gets the type of an element.

Returns: Element type, kElementUnknown otherwise.

◆ SetActualText()

virtual bool PdeElement::SetActualText ( const wchar_t * text )

pure virtual

Sets the actual text of the element.

Parameters

alt	The actual text to be set.

Returns: true if the actual text was set, false otherwise.

◆ SetAlt()

virtual bool PdeElement::SetAlt ( const wchar_t * alt )

pure virtual

Sets the alternate description of the element.

Parameters

alt	The alternate decsription to be set.

Returns: true if the description was set, false otherwise.

◆ SetBBox()

virtual bool PdeElement::SetBBox ( const PdfRect * bbox )

pure virtual

Gets the bounding box for an element in user space coordinates. To avoid the device-dependent effects of specifying objects in device space, PDF defines a device-independent coordinate system that always bears the same relationship to the current page, regardless of the output device on which printing or displaying occurs. This device-independent coordinate system is called user space. The origin of the user space(0, 0) represents the bottom-left corner of the PDF page. PDF files specify 72 points to 1 physical inch. The returned bounding box is guaranteed to encompass the element.

Parameters

bbox	A pointer to a PdfRect structure specifying the bounding box of an element, specified in user space coordinates.

◆ SetData()

virtual void PdeElement::SetData ( void * data )

pure virtual

Sets user-supplied data to pass to the element.

Parameters

data	User-supplied data to pass to element.

◆ SetFlags()

virtual bool PdeElement::SetFlags ( int flags )

pure virtual

Set the element state flags.

Parameters

flags the PdfElementFlags flags to be set

Returns: true if the element flags was set false othervise

◆ SetRender()

virtual void PdeElement::SetRender ( bool render )

pure virtual

Sets render mode of the element. This mode is used, when element is saved.

Parameters

mode	Render mode.
