Detailed Description

The QRawFont class provides access to a single physical instance of a font.

Since: 4.8 \inmodule QtGui

Note: QRawFont is a low level class. 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. It can be used in combination with the QGlyphRun 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 Linux platforms and CoreText on \macos. For other font back-ends, the APIs will be disabled.

QRawFont can be constructed in a number of ways: \list

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.
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.
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.

Member Enumeration Documentation

◆ AntialiasingType

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.

Enumerator
PixelAntialiasing
SubPixelAntialiasing

Definition at line 62 of file qrawfont.h.

◆ LayoutFlag

enum QRawFont::LayoutFlag

Since: 5.1

This enum tells the function advancesForGlyphIndexes() how to calculate the advances.

\value SeparateAdvances Will calculate the advance for each glyph separately. \value KernedAdvances Will apply kerning between adjacent glyphs. Note that OpenType GPOS based kerning is currently not supported. \value UseDesignMetrics Use design metrics instead of hinted metrics adjusted to the resolution of the paint device. Can be OR-ed with any of the options above.

Member Function Documentation

◆ advancesForGlyphIndexes() [1/4]

QList< QPointF > QRawFont::advancesForGlyphIndexes ( const QList< quint32 > & glyphIndexes ) const

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Returns the QRawFont's advances for each of the glyphIndexes in pixel units. The advances give the distance from the position of a given glyph to where the next glyph should be drawn to make it appear as if the two glyphs are unspaced. The advance of each glyph is calculated separately.

◆ advancesForGlyphIndexes() [2/4]

QList< QPointF > QRawFont::advancesForGlyphIndexes	(	const QList< quint32 > &	glyphIndexes,
		LayoutFlags	layoutFlags
	)		const

inline

Since: 5.1

Returns the QRawFont's advances for each of the glyphIndexes in pixel units. The advances give the distance from the position of a given glyph to where the next glyph should be drawn to make it appear as if the two glyphs are unspaced. How the advances are calculated is controlled by layoutFlags.

Note: When KernedAdvances is requested, this function will apply kerning rules from the TrueType table {KERN}, if this is available in the font. In many modern fonts, kerning is handled through OpenType rules or AAT rules, which requires a full shaping step to be applied. To get the results of fully shaping the text, use \l{QTextLayout}.

◆ advancesForGlyphIndexes() [3/4]

bool QRawFont::advancesForGlyphIndexes	(	const quint32 *	glyphIndexes,
		QPointF *	advances,
		int	numGlyphs
	)		const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Returns the QRawFont's advances for each of the glyphIndexes in pixel units. The advances give the distance from the position of a given glyph to where the next glyph should be drawn to make it appear as if the two glyphs are unspaced. The glyph indexes are given with the array glyphIndexes while the results are returned through advances, both of them must have numGlyphs elements. The advance of each glyph is calculated separately

bool QRawFont::advancesForGlyphIndexes	(	const quint32 *	glyphIndexes,
		QPointF *	advances,
		int	numGlyphs,
		LayoutFlags	layoutFlags
	)		const

Since: 5.1

Returns the QRawFont's advances for each of the glyphIndexes in pixel units. The advances give the distance from the position of a given glyph to where the next glyph should be drawn to make it appear as if the two glyphs are unspaced. The glyph indexes are given with the array glyphIndexes while the results are returned through advances, both of them must have numGlyphs elements. How the advances are calculated is controlled by layoutFlags.

Here is the call graph for this function:

◆ alphaMapForGlyph()

QImage QRawFont::alphaMapForGlyph	(	quint32	glyphIndex,
		AntialiasingType	antialiasingType = `SubPixelAntialiasing`,
		const QTransform &	transform = `QTransform()`
	)		const

This function returns a rasterized image of the glyph at the given glyphIndex in the underlying font, using the transform specified. If the QRawFont is not valid, this function will return an invalid QImage.

If the font is a color font, then the resulting image will contain the rendered glyph at the current pixel size. In this case, the antialiasingType will be ignored.

Otherwise, if 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. Otherwise, the image will be in the format of QImage::Format_Indexed8 and each pixel will contain the opacity of the pixel in the rasterization.

Here is the call graph for this function:

◆ ascent()

qreal QRawFont::ascent ( ) const

Returns the ascent of this QRawFont in pixel units.

The ascent of a font is the distance from the baseline to the highest position characters extend to. In practice, some font designers break this rule, e.g. when they put more than one accent on top of a character, or to accommodate an unusual character in an exotic language, so it is possible (though rare) that this value will be too small.

Here is the caller graph for this function:

◆ capHeight()

qreal QRawFont::capHeight ( ) const

Returns the cap height of this QRawFont in pixel units.

Since: 5.8

The cap height of a font is the height of a capital letter above the baseline. It specifically is the height of capital letters that are flat - such as H or I - as opposed to round letters such as O, or pointed letters like A, both of which may display overshoot.

See also: QFontMetricsF::capHeight()

Definition at line 367 of file qrawfont.cpp.

Here is the call graph for this function:

◆ descent()

qreal QRawFont::descent ( ) const

Returns the descent of this QRawFont in pixel units.

The descent is the distance from the base line to the lowest point characters extend to. In practice, some font designers break this rule, e.g. to accommodate an unusual character in an exotic language, so it is possible (though rare) that this value will be too small.

See also: QFontMetricsF::descent()

Here is the call graph for this function:

◆ familyName()

QString QRawFont::familyName ( ) const

Returns the family name of this QRawFont.

Definition at line 477 of file qrawfont.cpp.

Here is the call graph for this function:

◆ fontTable()

QByteArray QRawFont::fontTable ( const char * tagName ) const

Retrieves the sfnt table named tagName from the underlying physical font, or an empty byte array if no such table was found. The returned font table's byte order is Big Endian, like the sfnt format specifies. The tagName must be four characters long and should be formatted in the default endianness of the current platform.

Here is the caller graph for this function:

◆ fromFont()

QRawFont QRawFont::fromFont	(	const QFont &	font,
		QFontDatabase::WritingSystem	writingSystem = `QFontDatabase::Any`
	)

static

Fetches the physical representation based on a font query. The physical font returned is the font that will be preferred by Qt in order to display text in the selected writingSystem.

Warning: This function is potentially expensive and should not be called in performance sensitive code.

Here is the call graph for this function:

◆ glyphIndexesForChars()

bool QRawFont::glyphIndexesForChars	(	const QChar *	chars,
		int	numChars,
		quint32 *	glyphIndexes,
		int *	numGlyphs
	)		const

Converts a string of unicode points to glyph indexes using the CMAP table in the underlying font. The function works like glyphIndexesForString() except it take an array (chars), the results will be returned though glyphIndexes array and number of glyphs will be set in numGlyphs. The size of glyphIndexes array must be at least numChars, if that's still not enough, this function will return false, then you can resize glyphIndexes from the size returned in numGlyphs.

Definition at line 554 of file qrawfont.cpp.

◆ glyphIndexesForString()

QList< quint32 > QRawFont::glyphIndexesForString ( const QString & text ) const

Converts the string of unicode points given by text to glyph indexes using the CMAP table in the underlying font, and returns a list containing the result.

Note that, in cases where there are other tables in the font that affect the shaping of the text, the returned glyph indexes will not correctly represent the rendering of the text. To get the correctly shaped text, you can use QTextLayout to lay out and shape the text, then call QTextLayout::glyphs() to get the set of glyph index list and QRawFont pairs.
