◆ FontNameHasBoldItalicInfo()

bool PdfFontMetricsStandard14::FontNameHasBoldItalicInfo ( ) const

overridevirtual

State whether font name reports if the font is bold or italic, such has in "Helvetica-Bold"

Reimplemented from mm::PdfFontMetrics.

Returns: the ascender for this font

See also: GetAscent

Implements mm::PdfFontMetrics.

◆ GetBaseFontName()

string PdfFontMetricsStandard14::GetBaseFontName ( ) const

overridevirtual

Get a base name for the font that can be used to compose the final name, eg. "Arial"

Return empty string by default

Reimplemented from mm::PdfFontMetrics.

◆ GetBoundingBox()

void PdfFontMetricsStandard14::GetBoundingBox ( std::vector< double > & bbox ) const

overridevirtual

Create the bounding box vector in PDF units

Parameters

bbox	write the bounding box to this vector

Implements mm::PdfFontMetrics.

◆ GetDescent()

double PdfFontMetricsStandard14::GetDescent ( ) const

overridevirtual

Get the descent of this font in PDF units for the current font size. This value is usually negative!

Returns: the descender for this font

See also: GetDescent

Implements mm::PdfFontMetrics.

◆ GetFontData()

string_view PdfFontMetricsStandard14::GetFontData ( ) const

overridevirtual

Get the actual font data for a file loaded font, if available

For font data coming from the /FontFile keys, use GetFontDataObject()

Returns: a binary buffer of data containing the font data

Reimplemented from mm::PdfFontMetrics.

◆ GetItalicAngle()

double PdfFontMetricsStandard14::GetItalicAngle ( ) const

overridevirtual

Get the italic angle of this font. Used to build the font dictionay

Returns: the italic angle of this font.

Implements mm::PdfFontMetrics.

◆ GetLineSpacing()

double PdfFontMetricsStandard14::GetLineSpacing ( ) const

overridevirtual

Retrieve the line spacing for this font

Returns: the linespacing in PDF units

Implements mm::PdfFontMetrics.

◆ GetStemV()

double PdfFontMetricsStandard14::GetStemV ( ) const

overridevirtual

The thickness, measured horizontally, of the dominant vertical stems of glyphs in the font

Implements mm::PdfFontMetrics.

◆ GetStrikeOutPosition()

double PdfFontMetricsStandard14::GetStrikeOutPosition ( ) const

overridevirtual

Return the position of the strikeout for the current font size in PDF units

Returns: the underline position in PDF units

Implements mm::PdfFontMetrics.

◆ GetStrikeOutThickness()

double PdfFontMetricsStandard14::GetStrikeOutThickness ( ) const

overridevirtual

Get the width of the strikeout for the current font size in PDF units

Returns: the thickness of the strikeout in PDF units

Implements mm::PdfFontMetrics.

◆ GetUnderlinePosition()

double PdfFontMetricsStandard14::GetUnderlinePosition ( ) const

overridevirtual

Return the position of the underline for the current font size in PDF units

Returns: the underline position in PDF units

Implements mm::PdfFontMetrics.

◆ GetUnderlineThickness()

double PdfFontMetricsStandard14::GetUnderlineThickness ( ) const

overridevirtual

Get the width of the underline for the current font size in PDF units

Returns: the thickness of the underline in PDF units

Implements mm::PdfFontMetrics.

◆ GetWeight()

unsigned PdfFontMetricsStandard14::GetWeight ( ) const

overridevirtual

Get the weight of this font. Used to build the font dictionay

Returns: the weight of this font (500 is normal).

Implements mm::PdfFontMetrics.

◆ GetXHeight()

double PdfFontMetricsStandard14::GetXHeight ( ) const

overridevirtual

The font’s x height: the vertical coordinate of the top of flat nonascending lowercase letters (like the letter x), measured from the baseline, in fonts that have Latin characters

Implements mm::PdfFontMetrics.

◆ IsBold()

bool PdfFontMetricsStandard14::IsBold ( ) const

overridevirtual

Get whether the font style is bold

Implements mm::PdfFontMetrics.

◆ IsItalic()

bool PdfFontMetricsStandard14::IsItalic ( ) const

overridevirtual

Get whether the font style is italic

Implements mm::PdfFontMetrics.

◆ IsSymbol()

bool PdfFontMetricsStandard14::IsSymbol ( ) const

overridevirtual

Symbol fonts do need special treatment in a few cases. Use this method to check if the current font is a symbol font. Symbold fonts are detected by checking if they use FT_ENCODING_MS_SYMBOL as internal encoding.

Returns: true if this is a symbol font

Implements mm::PdfFontMetrics.
