For most purposes QFont is a more appropriate class. + + Most commonly, when presenting text in a user interface, the exact fonts used + to render the characters is to some extent unknown. This can be the case for several + reasons: For instance, the actual, physical fonts present on the target system could be + unexpected to the developers, or the text could contain user selected styles, sizes or + writing systems that are not supported by font chosen in the code. + + Therefore, Qt's QFont class really represents a query for fonts. When text is interpreted, + Qt will do its best to match the text to the query, but depending on the support, different + fonts can be used behind the scenes. + + For most use cases, this is both expected and necessary, as it minimizes the possibility of + text in the user interface being undisplayable. In some cases, however, more direct control + over the process might be useful. It is for these use cases the QRawFont class exists. + + A QRawFont object represents a single, physical instance of a given font in a given pixel size. + I.e. in the typical case it represents a set of TrueType or OpenType font tables and uses a + user specified pixel size to convert metrics into logical pixel units. In can be used in + combination with the QGlyphs class to draw specific glyph indexes at specific positions, and + also have accessors to some relevant data in the physical font. + + QRawFont only provides support for the main font technologies: GDI and DirectWrite on Windows + platforms, FreeType on Symbian and Linux platforms and CoreText on Mac OS X. For other + font back-ends, the APIs will be disabled. + + QRawFont can be constructed in a number of ways: + \list + \o \l It can be constructed by calling QTextLayout::glyphs() or QTextFragment::glyphs(). The + returned QGlyphs objects will contain QRawFont objects which represent the actual fonts + used to render each portion of the text. + \o \l It can be constructed by passing a QFont object to QRawFont::fromFont(). The function + will return a QRawFont object representing the font that will be selected as response to + the QFont query and the selected writing system. + \o \l It can be constructed by passing a file name or QByteArray directly to the QRawFont + constructor, or by calling loadFromFile() or loadFromData(). In this case, the + font will not be registered in QFontDatabase, and it will not be available as part of + regular font selection. + \endlist + + QRawFont is considered local to the thread in which it is constructed (either using a + constructor, or by calling loadFromData() or loadFromFile()). The QRawFont cannot be moved to a + different thread, but will have to be recreated in the thread in question. + + \note For the requirement of caching glyph indexes and font selections for static text to avoid + reshaping and relayouting in the inner loop of an application, a better choice is the QStaticText + class, since it optimizes the memory cost of the cache and also provides the possibility of paint + engine specific caches for an additional speed-up. +*/ + +/*! + \enum QRawFont::AntialiasingType + + This enum represents the different ways a glyph can be rasterized in the function + alphaMapForGlyph(). + + \value PixelAntialiasing Will rasterize by measuring the coverage of the shape on whole pixels. + The returned image contains the alpha values of each pixel based on the coverage of + the glyph shape. + \value SubPixelAntialiasing Will rasterize by measuring the coverage of each subpixel, + returning a separate alpha value for each of the red, green and blue components of + each pixel. +*/ + +/*! + Constructs an invalid QRawFont. +*/ +QRawFont::QRawFont() + : d(new QRawFontPrivate) +{ +} + +/*! + Constructs a QRawFont representing the font contained in the file referenced by \a fileName, + with \a pixelSize size in pixels, and the selected \a hintingPreference. + + \note The referenced file must contain a TrueType or OpenType font. +*/ +QRawFont::QRawFont(const QString &fileName, + int pixelSize, + QFont::HintingPreference hintingPreference) + : d(new QRawFontPrivate) +{ + loadFromFile(fileName, pixelSize, hintingPreference); +} + +/*! + Constructs a QRawFont representing the font contained in \a fontData. + + \note The data must contain a TrueType or OpenType font. +*/ +QRawFont::QRawFont(const QByteArray &fontData, + int pixelSize, + QFont::HintingPreference hintingPreference) + : d(new QRawFontPrivate) +{ + loadFromData(fontData, pixelSize, hintingPreference); +} + +/*! + Creates a QRawFont which is a copy of \a other. +*/ +QRawFont::QRawFont(const QRawFont &other) +{ + d = other.d; +} + +/*! + Destroys the QRawFont +*/ +QRawFont::~QRawFont() +{ +} + +/*! + Assigns \a other to this QRawFont. +*/ +QRawFont &QRawFont::operator=(const QRawFont &other) +{ + d = other.d; + return *this; +} + +/*! + Returns true if the QRawFont is valid and false otherwise. +*/ +bool QRawFont::isValid() const +{ + Q_ASSERT(d->thread == 0 || d->thread == QThread::currentThread()); + return d->fontEngine != 0; +} + +/*! + Replaces the current QRawFont with the contents of the file references by \a fileName. + + The file must reference a TrueType or OpenType font. + + \sa loadFromData() +*/ +void QRawFont::loadFromFile(const QString &fileName, + int pixelSize, + QFont::HintingPreference hintingPreference) +{ + QFile file(fileName); + if (file.open(QIODevice::ReadOnly)) + loadFromData(file.readAll(), pixelSize, hintingPreference); +} + +/*! + Replaces the current QRawFont with the contents of \a fontData. + + The \a fontData must contain a TrueType or OpenType font. + + \sa loadFromFile() +*/ +void QRawFont::loadFromData(const QByteArray &fontData, + int pixelSize, + QFont::HintingPreference hintingPreference) +{ + detach(); + d->cleanUp(); + d->hintingPreference = hintingPreference; + d->thread = QThread::currentThread(); + d->platformLoadFromData(fontData, pixelSize, hintingPreference); +} + +/*! + This function returns a rasterized image of the glyph at a given \a glyphIndex in the underlying + font, if the QRawFont is valid, otherwise it will return an invalid QImage. + + If \a antialiasingType is set to QRawFont::SubPixelAntialiasing, then the resulting image will be + in QImage::Format_RGB32 and the RGB values of each pixel will represent the subpixel opacities of + the pixel in the rasterization of the glyph.
