getFontBoundingBox

public PDRectangle getFontBoundingBox()
                               throws java.io.IOException

This will get the fonts bouding box.

Overrides:

getFontBoundingBox in class PDSimpleFont

Returns:

The fonts bouding box.

Throws:

java.io.IOException - If there is an error getting the font bounding box.

getDefaultWidth

public long getDefaultWidth()

This will get the default width. The default value for the default width is 1000.

Returns:

The default width for the glyphs in this font.

setDefaultWidth

public void setDefaultWidth(long dw)

This will set the default width for the glyphs of this font.

Parameters:

dw - The default width.

getFontWidth

public float getFontWidth(byte[] c,
                          int offset,

Throws:

java.io.IOException - If an error occurs while parsing.

getFontHeight

public float getFontHeight(byte[] c,
                           int offset,
                           int length)
                    throws java.io.IOException

This will get the font height for a character.

Overrides:

getFontHeight in class PDSimpleFont

Parameters:
