Modifier and Type | Method and Description |
---|---|
protected byte[] |
encode(int unicode)
Encodes the given Unicode code point for use in a PDF content stream.
|
BoundingBox |
getBoundingBox()
Returns the font's bounding box.
|
PDType3CharProc |
getCharProc(int code)
Returns the stream of the glyph for the given character code
|
COSDictionary |
getCharProcs()
Returns the dictionary containing all streams to be used to render the glyphs.
|
Vector |
getDisplacement(int code)
Returns the displacement vector (w0, w1) in text space, for the given character.
|
PDRectangle |
getFontBBox()
This will get the fonts bounding box from its dictionary.
|
FontBoxFont |
getFontBoxFont()
Returns the embedded or system font used for rendering.
|
Matrix |
getFontMatrix()
Returns the font matrix, which represents the transformation from glyph space to text space.
|
float |
getHeight(int code)
Returns the height of the given character, in glyph space.
|
String |
getName()
Returns the name of this font, either the PostScript "BaseName" or the Type 3 "Name".
|
GeneralPath |
getPath(String name)
Returns the path for the character with the given name.
|
PDResources |
getResources()
Returns the optional resources of the type3 stream.
|
float |
getWidth(int code)
Returns the advance width of the given character, in glyph space.
|
float |
getWidthFromFont(int code)
Returns the width of a glyph in the embedded font file.
|
boolean |
hasGlyph(String name)
Returns true if the font contains the character with the given name.
|
boolean |
isDamaged()
Returns true if the embedded font file is damaged.
|
boolean |
isEmbedded()
Returns true if the font file is embedded in the PDF.
|
protected Boolean |
isFontSymbolic()
Internal implementation of isSymbolic, allowing for the fact that the result may be
indeterminate.
|
int |
readCode(InputStream in)
Reads a character code from a content stream string.
|
protected void |
readEncoding()
Reads the Encoding from the Font dictionary or the embedded or substituted font file.
|
protected Encoding |
readEncodingFromFont()
Called by readEncoding() if the encoding needs to be extracted from the font file.

PDFontLike.getWidth(int)
method returns the advance width of a glyph,
but there is no corresponding advance height. The logical height of a character is the same
for every character in a font, so if you want that, retrieve the font bbox's height.
Otherwise if you want the visual bounds of the glyph then call getPath(..) on the appropriate
PDFont subclass to retrieve the glyph outline as a GeneralPath.getHeight
