All Implemented Interfaces:

Serializable

public class PdfType3Font
extends PdfSimpleFont<Type3FontProgram>

Low-level API class for Type 3 fonts.

In Type 3 fonts, glyphs are defined by streams of PDF graphics operators. These streams are associated with character names. A separate encoding entry maps character codes to the appropriate character names for the glyphs.

To be able to be wrapped with this PdfObjectWrapper the PdfObject must be indirect.

Method Detail

getType3Glyph

public Type3Glyph getType3Glyph(int unicode)

isSubset

public boolean isSubset()

Description copied from class: PdfFont

Indicates if all the glyphs and widths for that particular encoding should be included in the document.

Overrides:

isSubset in class PdfFont

Returns:

false to include all the glyphs and widths.

isEmbedded

public boolean isEmbedded()

Overrides:

isEmbedded in class PdfFont

getFontMatrix

public double[] getFontMatrix()

Overrides:

getFontMatrix in class PdfFont

setFontMatrix

public void setFontMatrix(double[] fontMatrix)

addGlyph

public Type3Glyph addGlyph(char c,
                           int wx,
                           int llx,
                           int lly,
                           int urx,
                           int ury)

Defines a glyph. If the character was already defined it will return the same content

Parameters:

c - the character to match this glyph.

wx - the advance this character will have

llx - the X lower left corner of the glyph bounding box. If the colorize option is true the value is ignored

lly - the Y lower left corner of the glyph bounding box. If the colorize option is true the value is ignored

urx - the X upper right corner of the glyph bounding box. If the colorize option is true the value is ignored

ury - the Y upper right corner of the glyph bounding box. If the colorize option is true the value is ignored

Returns:

a content where the glyph can be defined

getGlyph

public Glyph getGlyph(int unicode)

Specified by:

getGlyph in class PdfFont

getFontDescriptor

protected PdfDictionary getFontDescriptor(String fontName)

Description copied from class: PdfSimpleFont

Generates the font descriptor for this font or null if it is one of the 14 built in fonts.

Overrides:

getFontDescriptor in class PdfSimpleFont<Type3FontProgram>

Returns:

the PdfDictionary containing the font descriptor or null.

addFontStream

protected void addFontStream(PdfDictionary fontDescriptor)

Specified by:

addFontStream in class PdfSimpleFont<Type3FontProgram>

getDocument

protected PdfDocument getDocument()

flush

public void flush()

Overrides:

flush in class PdfObjectWrapper<PdfDictionary>
