Optional checks before reading By default does nothing.
Reimplemented from PoDoFo::InputStream.
◆ Peek()
Peek at next char in stream.
/returns true if success, false if EOF is encountered before peeking the character
◆ peek()
Peek at next char in stream.
/returns true if success, false if EOF
Implemented in PoDoFo::NullStreamDevice, and PoDoFo::PdfCanvasInputDevice.
