/* * @doc INTERNAL * * @module _CFPF.H -- RichEdit CCharFormat and CParaFormat Classes | * * These classes are derived from the RichEdit 1.0 CHARFORMAT and PARAFORMAT * structures and are the RichEdit 2.0 internal versions of these structures. * Member functions (like Copy()) that use external (API) CHARFORMATs and * PARAFORMATs need to check the
value to see what members are * defined. Default values that yield RichEdit 1.0 behavior should be stored * for RichEdit 1.0 format structures, e.g., so that the renderer doesn't do * anomalous things with random RichEdit 2.0 format values. Generally the * appropriate default value is 0. * * All character and paragraph format measurements are in twips. Undefined * mask and effect bits are reserved and must be 0 to be compatible with * future versions. * * Effects that appear with an asterisk (*) are stored, but won't be * displayed by RichEdit 2.0. They are place holders for TOM and/or Word * compatibility. * * Note: these structures are much bigger than they need to be for internal * use especially if we use SHORTs instead of LONGs for dimensions and * the tab and font info are accessed via ptrs. Nevertheless, in view of our * tight delivery schedule, RichEdit 2.0 uses the classes below. * * History: * 9/1995 -- MurrayS: Created * 11/1995 -- MurrayS: Extended to full Word97 FormatFont/Format/Para * * Copyright (c) 1995-1997, Microsoft Corporation.
