pure virtual

Gets the bounding box of a character.

Parameters

index	Index of the character in a text object.
bbox	(Filled by the method) A pointer to a PdfRect structure specifying the bounding box of the character.

Returns: true if the bbox was successfully retrieved. false otherwise

Parameters

index	Index of the character in a text object.
buffer	(filled by method) If the buffer is null function returns required length of string
len	Length of a buffer to be filled in.

Returns: Number of characters written into buffer of required length.

◆ GetNumChars()

virtual int PdsText::GetNumChars ( ) const

pure virtual

Gets the number of characters in a text object.

Returns: Number of characters in a text object.

◆ GetText()

virtual int PdsText::GetText	(	wchar_t *	buffer,
		int	len
	)		const

pure virtual

Gets the text of the page text element.

Parameters

buffer	(filled by method) If the buffer is null function returns required length of string
len	Length of a buffer to be filled in.

Returns: Number of characters written into buffer of required length.

◆ GetTextMatrix()

virtual bool PdsText::GetTextMatrix ( PdfMatrix * matrix ) const

pure virtual

Parameters

matrix (Filled by the method) Pointer to the text transformation matrix.

◆ GetTextState()

virtual bool PdsText::GetTextState ( PdfTextState * text_state )

pure virtual

Gets the text state of the text element.

Parameters

text_state (filled by method) A pointer to a PdfTextState structure specifying the text state of a text object.

Returns: true if the text state was successfully retrieved. false otherwise

◆ SetCharStateFlags()

virtual bool PdsText::SetCharStateFlags	(	int	index,
		PdfStateFlags	flags
	)

pure virtual

Set the text object state flags for character.

Parameters

flags the PdfStateFlags flags to be set

Returns: true if the object's state flags was set false otherwise

◆ SetText()

virtual void PdsText::SetText ( const wchar_t * buffer )

pure virtual

Sets the text of the page text element.

Parameters

buffer	Text to be set.
len	Length of a buffer to be set.

◆ SetTextState()

virtual void PdsText::SetTextState ( const PdfTextState * text_state )

pure virtual

Sets the text state of the text element.

Parameters

text_state A pointer to a PdfTextState structure specifying the text state of a text object.

◆ SplitAtChar()

virtual PdsText * PdsText::SplitAtChar ( int index )

pure virtual

Splits text object into two.

Parameters

index Index of the character in a text object where split should be done. The first text object is from character index 0 up to index. The second text object is from index + 1 to the end of the run.

Returns: Pointer to a newly created PdsText.
