Method Detail

getFamilyFontName

public String[][] getFamilyFontName()

Gets the family name of the font. If it is a True Type font each array element will have {Platform ID, Platform Encoding ID, Language ID, font name}. The interpretation of this values can be found in the Open Type specification, chapter 2, in the 'name' table.
For the other fonts the array has a single element with {"", "", "", font name}.

Specified by:

getFamilyFontName in class BaseFont

Returns:

the family name of the font

getFontDescriptor

public float getFontDescriptor(int key,
                               float fontSize)

Gets the font parameter identified by key. Valid values for key are ASCENT, CAPHEIGHT, DESCENT, ITALICANGLE, BBOXLLX, BBOXLLY, BBOXURX and BBOXURY.

Specified by:

getFontDescriptor in class BaseFont

Parameters:

key - the parameter to be extracted

fontSize - the font size in points

Returns:

the parameter in points

getFullFontName

public String[][] getFullFontName()

Gets the full name of the font. If it is a True Type font each array element will have {Platform ID, Platform Encoding ID, Language ID, font name}. The interpretation of this values can be found in the Open Type specification, chapter 2, in the 'name' table.
For the other fonts the array has a single element with {"", "", "", font name}.

Specified by:

getFullFontName in class BaseFont

Returns:

the full name of the font

getKerning

public int getKerning(char char1,
                      char char2)

Gets the kerning between two Unicode chars.

Specified by:

getKerning in class BaseFont

Parameters:

char1 - the first char

char2 - the second char

Returns:

the kerning to be applied

getPostscriptFontName

public String getPostscriptFontName()

Gets the postscript font name.

Specified by:

getPostscriptFontName in class BaseFont

Returns:

the postscript font name

hasKernPairs

public boolean hasKernPairs()

Checks if the font has any kerning pairs.

Specified by:

hasKernPairs in class BaseFont

Returns:

true if the font has any kerning pairs

getWidth

public int getWidth(String text)

Description copied from class: BaseFont

Gets the width of a String in normalized 1000 units.

Overrides:

getWidth in class BaseFont

Parameters:

text - the String to get the witdth of

Returns:

the width in normalized 1000 units

charExists

public boolean charExists(char c)

Description copied from class: BaseFont

Checks if a character exists in this font.

Overrides:

charExists in class BaseFont

Parameters:

c - the character to check

Returns:

true if the character has a glyph, false otherwise

setPostscriptFontName

public void setPostscriptFontName(String name)

Sets the font name that will appear in the pdf font dictionary. It does nothing in this case as the font is already in the document.

Specified by:

setPostscriptFontName in class BaseFont

Parameters:

name - the new font name

setKerning

public boolean setKerning(char char1,
                          char char2,
                          int kern)

Description copied from class: BaseFont

Sets the kerning between two Unicode chars.

Specified by:

setKerning in class BaseFont

Parameters:

char1 - the first char

char2 - the second char

kern - the kerning to apply in normalized 1000 units

Returns:

true if the kerning was applied, false otherwise

getCharBBox

public int[] getCharBBox(char c)

Description copied from class: BaseFont

Gets the smallest box enclosing the character contours. It will return null if the font has not the information or the character has no contours, as in the case of the space, for example. Characters with no contours may also return [0,0,0,0].

Overrides:

getCharBBox in class BaseFont

Parameters:

c - the character to get the contour bounding box from

Returns:

an array of four floats with the bounding box in the format [llx,lly,urx,ury] or null

getRawCharBBox

protected int[] getRawCharBBox(int c,
                               String name)

Specified by:

getRawCharBBox in class BaseFont
