Constructor Detail

TrueTypeFontProgram

public TrueTypeFontProgram(ASInputStream stream,
                           boolean isSymbolic,
                           COSObject encoding)
                    throws IOException

Constructor from stream containing font data, and encoding details.

Parameters:

stream - is stream containing font data.

isSymbolic - is true if font is marked as symbolic.

encoding - is value of /Encoding in font dictionary.

Throws:

IOException - if creation of @{link SeekableStream} fails.
