PDFFontDescriptor
public PDFFontDescriptor(java.lang.String basefont,
int ascent,
int descent,
int capHeight,
int flags,
PDFRectangle fontBBox,
int italicAngle,
int stemV)
- Create the /FontDescriptor object
- Parameters:
ascent
- the maximum height above the baselinedescent
- the maximum depth below the baselinecapHeight
- height of the capital lettersflags
- various characteristics of the fontfontBBox
- the bounding box for the described fontbasefont
- the base font nameitalicAngle
- the angle of the vertical dominant strokesstemV
- the width of the dominant vertical stems of glyphs
setMetrics
public void setMetrics(int avgWidth,
int maxWidth,
int missingWidth,
int leading,
int stemH,
int xHeight)
- Set the optional metrics.
- Parameters:
avgWidth
- The average width of characters in this font.
The default value is 0.maxWidth
- The maximum width of characters in this font.
The default value is 0.missingWidth
- missing widthleading
- the desired spacing between lines of text.
The default value is 0.stemH
- The vertical width of the dominant horizontal stems of
glyphs in the font. The default value is 0.xHeight
- The y-coordinate of the top of flat non-ascending
lowercase letters, measured from the baseline. The default value is 0.
setFontFile
public void setFontFile(FontType subtype,
AbstractPDFStream fontfile)
- Set the optional font file stream
- Parameters:
subtype
- the font type defined in the font streamfontfile
- the stream containing an embedded font
getFontFile
public AbstractPDFStream getFontFile()
- Returns:
- the FontFile or null if the font is not embedded
toPDFString
public java.lang.String toPDFString()
- Description copied from class:
PDFObject
- This method returns a String representation of the PDF object. The result
is normally converted/encoded to a byte array by toPDF(). Only use
this method to implement the serialization if the object can be fully
represented as text. If the PDF representation of the object contains
binary content use toPDF() or output(OutputStream) instead.
- Overrides:
toPDFString
in class PDFObject
- See Also:
PDFObject.toPDFString()
fillInPDF
protected void fillInPDF(java.lang.StringBuffer begin)
- Fill in the specifics for the font's descriptor.
The given buffer already contains the fields common to all descriptors.
- Parameters:
begin
- the buffer to be completed with the specific fields
