Method Detail

load

public static CFFFont[] load(FontByteArray buffer)
                      throws IOException,
                             InvalidFontException,
                             UnsupportedFontException

Given buffer of font data, creates cff FontData objects that represent it. Note that fonts are parsed at this point.

Returns:

An array of cff fonts

Throws:

IOException - Thrown if the stream cannot be read

InvalidFontException - Thrown if the stream does not represent a valid cff font.

UnsupportedFontException - Thrown if the stream represents an unsupported cff font.

getNumBytesNeededToIdentify

public static int getNumBytesNeededToIdentify()

Returns:

the minimum number of bytes needed to try to identify whether a font stream contains cff

isCFF

public static boolean isCFF(byte[] startingBytes)

This is a very loose check to see if the font looks like CFF. Since these fonts don't have as solid of a way of identifying them as other fonts do, this check should only be used when checks for other fonttypes have failed.

Parameters:

startingBytes - bytes from the start of the font stream. Must contain at least getNumBytesNeededToIdentify bytes.

Returns:

true of the font appears to be cff. false otherwise.
