Syntax

public class CharData : IDisposable

Properties

bytes

the number of bytes representing this character in char_data buffer. For simple fonts 'bytes' will equal 1. For multibyte (CID or Type0) fonts 'bytes may be larger than 1.

Declaration

public int bytes { get; set; }

Property Value

Type	Description
System.Int32	the number of bytes representing this character in char_data buffer. 1 for symple fonts.

char_code

Gets the char code.

Declaration

public int char_code { get; set; }

Property Value

Type	Description
System.Int32	Char code' For SimpleFonts char_code := char_data[0] for composite fonts char_code is the numeric value of data stored in char_data buffer.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

char_data[Int32]

Gets the char data.

Declaration

public byte char_data { get; }

Parameters

Type	Name	Description
System.Int32	i

Property Value

Type	Description
System.Byte	A buffer containing character data. For simple fonts each character is represented by a single byte. For multibyte (CID or Type0) fonts each character may take more than one byte.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

x

To render text, a virtual point (x, y), located on the baseline, called the pen position, is used to locate glyphs.

The pen position has already taken into account the effects of any inter-character adjustments due to properties such as font size, text rise, character spacing, word spacing and positioning adjustments on 'TJ' elements.

Declaration

public double x { get; set; }

Property Value

Type	Description
System.Double	glyph horizontal position

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

y

Gets the glyph y.

Declaration

public double y { get; set; }

Property Value

Type	Description
System.Double	glyph vertical position

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

Methods

Parameters

Type	Name	Description

Finalize()

Allows a CharData to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Declaration

protected void Finalize()

get_char_data(Int32)

Declaration

public byte get_char_data(int i)

Parameters
