方法详细资料

loadFonts

public static Font[] loadFonts(InputStream is)
                        throws IOException

Load the font(s) from the input stream. The current settings on the factory are used during the loading process. One or more fonts are returned if the stream contains valid font data. Some font container formats may have more than one font and in this case multiple font objects will be returned. If the data in the stream cannot be parsed or is invalid an array of size zero will be returned.

参数:

is - the input stream font data

返回:

one or more fonts

抛出:

IOException

loadFontsForBuilding

public static Font.Builder[] loadFontsForBuilding(InputStream is)
                                           throws IOException

Load the font(s) from the input stream into font builders. The current settings on the factory are used during the loading process. One or more font builders are returned if the stream contains valid font data. Some font container formats may have more than one font and in this case multiple font builder objects will be returned. If the data in the stream cannot be parsed or is invalid an array of size zero will be returned.

参数:

is - the input stream font data

返回:

one or more font builders

抛出:

IOException
