Constructor Detail

PdfFont

public PdfFont(PdfData pdd)

PdfFont

public PdfFont(PdfData pdd,
               java.lang.String fontName,
               PdfFont existingFont)

Constructor for cloning an existing PdfFont, but specifying a different typeface.

Parameters:

pdd - PDF data

fontName - the name of the new font/typeface

existingFont - the font to clone the other attributes from

Method Detail

setToDefault

public void setToDefault()

Initializes all PdfFont fields to defaults, and sets line number to 0

clone

public PdfFont clone()

Overrides:

clone in class java.lang.Object

createFont

com.lowagie.text.Font createFont(PdfFont f)

Creates an iText Font object based on the class fields

Parameters:

f - the PdfFont containing the parameters for the font

Returns:

the iText Font object

getIdentityHFont

com.lowagie.text.Font getIdentityHFont(java.lang.String fontName,
                                       float size,
                                       int style)

Opens a font using the IDENTITY-H encoding.

Parameters:

fontName - the name assigned to the font in the font list

size - the size in points

style - bold, italic, etc.

Returns:

the Font if opened; null if the file could not be opened or an error occurred.

isFileOtf

private boolean isFileOtf(java.lang.String fontName)

Looks up a font in the fontlist and determines whether it uses the .otf font format.

Parameters:

fontName - name of font to verify

Returns:

true if it's an .otf font, otherwise false.

getCp1252Font

com.lowagie.text.Font getCp1252Font(java.lang.String fontName,
                                    float size,
                                    int style)

Gets the font with CP1252 (aka WINANSI) encoding

Parameters:

fontName - name of font to get

size - size in points

style - bold, italic, etc.

Returns:

the font, or null if an error occurred.

isBase14Font

boolean isBase14Font(java.lang.String fontName)

Determines whehter the current font is one of the Base14 Acrobat fonts, built into every PDF reader. These fonts require special hanldling, and so this routine helps identify them, based on their font face name.

Parameters:

fontName - name of the font face

Returns:

true if it's a base14 font name, false otherwise.

createItextFontName

java.lang.String createItextFontName(PdfFont f)

Get the name by which iText refers to this font. This routine is mostly occupied with the special handling of the base14 fonts. For all other fonts, this method makes sure the font is registered with iText and returns its name as registered by iText (which is the family name for the font).

Parameters:

f - PdfFont whose iText name we're getting

Returns:

a string containing the iText usable name for this font.

findAndRegisterFont

boolean findAndRegisterFont(java.lang.String typefaceName)

Get the filenames from the typefaceMap and register them in iText's FontFactory.

Parameters:

typefaceName - name of the typeface

Returns:

true if the font is now registered, false if an error occurred. (Font was not in fontlist.)

registerOneFont

void registerOneFont(java.lang.String fontFile,
                     java.lang.String typeface)

Unfortunately, iText does not pass along the exception if the file cannot be found. Rather, iText rethrows the exception internally and prints the stack trace. So, the only way to avoid this is to check for each file first before doing the registration.

Parameters:

fontFile - the file location and name

typeface - the name of the typeface to register the font for

registerFont

private void registerFont(java.lang.String fontFile,
                          java.lang.String typeface)

Actual font registration. Takes care of specious warning emitted by iText registering a TrueType collection (.ttc) file

Parameters:

fontFile - the complete filename including the path

typeface - the name by which the typeface is registered.

ttcFileErrorMsg

void ttcFileErrorMsg(GDD gdd,
                     java.lang.String fontFile)

lookupFontFilenames

java.lang.String[] lookupFontFilenames(java.lang.String typefaceName)

Get the names of the actual font files that are the implementation of this typeface

Parameters:

typefaceName - the typefaces

Returns:

an array of strings containing the file names.

computeItextStyle

int computeItextStyle()

iText font style captures bold, italic, strikethru, underline. Since we handle strikethrough and underline ourselves, we use it to communicate italic and bold only. This computation done here.

Returns:

the iText Style

getBold

public boolean getBold()

getItalics

public boolean getItalics()

getItextFont

public com.lowagie.text.Font getItextFont()

Get the iText font

Returns:

the iText font

getFace

public java.lang.String getFace()

getSize

public float getSize()

getSource

public Source getSource()

setBold

public void setBold(boolean onOff,
                    Source newSource)

set bold on/off and re-create the iText font to record the change.

Parameters:

onOff - the new value for the italics setting

newSource - the file and line # of the token that changed italics

setItalics

public void setItalics(boolean onOff,
                       Source newSource)

set italics on/off and re-create the iText font to record the change.

Parameters:

onOff - the new value for the italics setting

newSource - the file and line # of the token that changed italics

setSize

public void setSize(float newSize,
                    Source newSource)

setFace

public void setFace(java.lang.String newFace,
                    Source newSource)
