Method Detail
-
getFontBoxFont
public FontBoxFont getFontBoxFont()
Description copied from class:PDSimpleFont
Returns the embedded or system font used for rendering. This is never null.- Specified by:
getFontBoxFont
in classPDSimpleFont
-
getBaseFont
public final java.lang.String getBaseFont()
Returns the PostScript name of the font.
-
getPath
public java.awt.geom.GeneralPath getPath(java.lang.String name) throws java.io.IOException
Description copied from class:PDSimpleFont
Returns the path for the character with the given name. For some fonts, GIDs may be used instead of names when calling this method.- Specified by:
getPath
in classPDSimpleFont
- Returns:
- glyph path
- Throws:
java.io.IOException
- if the path could not be read
-
hasGlyph
public boolean hasGlyph(java.lang.String name) throws java.io.IOException
Description copied from class:PDSimpleFont
Returns true if the font contains the character with the given name.- Specified by:
hasGlyph
in classPDSimpleFont
- Throws:
java.io.IOException
- if the path could not be read
-
getName
public final java.lang.String getName()
Description copied from interface:PDFontLike
Returns the name of this font, either the PostScript "BaseName" or the Type 3 "Name".
-
getBoundingBox
public BoundingBox getBoundingBox() throws java.io.IOException
Description copied from interface:PDFontLike
Returns the font's bounding box.- Throws:
java.io.IOException
-
generateBoundingBox
private BoundingBox generateBoundingBox() throws java.io.IOException
- Throws:
java.io.IOException
-
codeToName
public java.lang.String codeToName(int code)
-
readEncodingFromFont
protected Encoding readEncodingFromFont() throws java.io.IOException
Description copied from class:PDSimpleFont
Called by readEncoding() if the encoding needs to be extracted from the font file.- Specified by:
readEncodingFromFont
in classPDSimpleFont
- Throws:
java.io.IOException
- if the font file could not be read.
-
readCode
public int readCode(java.io.InputStream in) throws java.io.IOException
Description copied from class:PDFont
Reads a character code from a content stream string. Codes may be up to 4 bytes long.
-
getFontMatrix
public final Matrix getFontMatrix()
Description copied from interface:PDFontLike
Returns the font matrix, which represents the transformation from glyph space to text space.- Specified by:
getFontMatrix
in interfacePDFontLike
- Overrides:
getFontMatrix
in classPDFont
-
isDamaged
public boolean isDamaged()
Description copied from interface:PDFontLike
Returns true if the embedded font file is damaged.
-
getWidthFromFont
public float getWidthFromFont(int code) throws java.io.IOException
Description copied from interface:PDFontLike
Returns the width of a glyph in the embedded font file.- Parameters:
code
- character code- Returns:
- width in glyph space
- Throws:
java.io.IOException
- if the font could not be read
-
isEmbedded
public boolean isEmbedded()
Description copied from interface:PDFontLike
Returns true if the font file is embedded in the PDF.
-
getHeight
public float getHeight(int code) throws java.io.IOException
Description copied from interface:PDFontLike
Returns the height of the given character, in glyph space. This can be expensive to calculate. Results are only approximate.Warning: This method is deprecated in PDFBox 2.0 because there is no meaningful value which it can return. The
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. See the cyan rectangles in the DrawPrintTextLocations.java example to see this in action.- Parameters:
code
- character code- Throws:
java.io.IOException
-
encode
protected byte[] encode(int unicode) throws java.io.IOException
Description copied from class:PDFont
Encodes the given Unicode code point for use in a PDF content stream. Content streams use a multi-byte encoding with 1 to 4 bytes.This method is called when embedding text in PDFs and when filling in fields.
-
getStringWidth
public float getStringWidth(java.lang.String string) throws java.io.IOException
Description copied from class:PDFont
Returns the width of the given Unicode string.- Overrides:
getStringWidth
in classPDFont
- Parameters:
string
- The text to get the width of.- Returns:
- The width of the string in 1/1000 units of text space.
- Throws:
java.io.IOException
- If there is an error getting the width information.
-
getAverageFontWidth
public float getAverageFontWidth()
Description copied from class:PDFont
This will get the average font width for all characters.- Specified by:
getAverageFontWidth
in interfacePDFontLike
- Overrides:
getAverageFontWidth
in classPDFont
- Returns:
- The width is in 1000 unit of text space, ie 333 or 777
-
getCFFType1Font
public CFFType1Font getCFFType1Font()
Returns the embedded Type 1-equivalent CFF font.- Returns:
- the cffFont
-
getAverageCharacterWidth
private float getAverageCharacterWidth()
-
getNameInFont
private java.lang.String getNameInFont(java.lang.String name) throws java.io.IOException
Maps a PostScript glyph name to the name in the underlying font, for example when using a TTF font we might map "W" to "uni0057".- Throws:
java.io.IOException
