Syntax

public sealed class ShapedText : IDisposable

Methods

Dispose()

Declaration

public override sealed void Dispose()

Dispose(Boolean)

Declaration

[HandleProcessCorruptedStateExceptions]
protected void Dispose(bool A_0)

Parameters

Type	Name	Description
System.Boolean	A_0

Finalize()

Declaration

protected void Finalize()

GetFailureReason()

In the case where GetShapingStatus() returns something other than FullShaping, this method will return a more detailed reason behind the failure.

Declaration

public ShapedText.FailureReason GetFailureReason()

Returns

Type	Description
ShapedText.FailureReason

GetGlyph(Int32)

Get the glyph ID at the indicated place in the shaped sequence. This number is specific to the font file used to generate the shaping results, and does not always have a clean mapping to a particular Unicode codepoint in the original string.

Declaration

public int GetGlyph(int index)

Parameters

Type	Name	Description
System.Int32	index	the index of the glyph to be retrieved. Must be less than GetNumGlyphs()

Returns

Type	Description
System.Int32	returns the glyph ID for the indicated place in the shaped result

GetGlyphXPos(Int32)

The X position of the glyph at the requested index. This number has been scaled by GetScale().

Declaration

public double GetGlyphXPos(int index)

Parameters

Type	Name	Description
System.Int32	index	the index of the glyph position to be retrieved. Must be less than GetNumGlyphs()

Returns

Type	Description
System.Double	returns the X position for the glyph at the specified index

GetGlyphYPos(Int32)

The Y position of the glyph at the requested index. This number has been scaled by GetScale().

Declaration

public double GetGlyphYPos(int index)

Parameters

Type	Name	Description
System.Int32	index	the index of the glyph position to be retrieved. Must be less than GetNumGlyphs()

Returns

Type	Description
System.Double	returns the Y position for the glyph at the specified index

GetNumGlyphs()

Number of glyphs present in the shaped text. Might be different from the .

Declaration

public int GetNumGlyphs()

Returns

Type	Description
System.Int32	returns the number of utf32 codepoints in this shaped text

GetScale()

Scaling factor of this shaped text relative to the em size. A scaling factor of 1 means that all units are relative to the em size. PDF scaling is typically 1000 units per em.

Declaration

public double GetScale()

Returns

Type	Description
System.Double	returns the scaling factor for the glyph positions

GetShapingStatus()

Get the state of the shaping operation. Even if the shaping did not fully succeed, this object can be added to an elementbuilder, and will fallback to placing unshped text. See GetFailureReason() in the case this method returns something other than FullShaping.

Declaration

public ShapedText.ShapingStatus GetShapingStatus()

Returns

Type	Description
ShapedText.ShapingStatus

GetText()

The original source text string.

Declaration

public string GetText()

Returns

Type	Description
System.String	returns the source text string

System.IDisposable
