Member Function Documentation

◆ bold()

auto xtd::drawing::font::bold ( ) const -> bool

nodiscardnoexcept

Gets a value that indicates whether this xtd::drawing::font is bold.

Returns: true if this xtd::drawing::font is bold; otherwise, false.

◆ font_family()

auto xtd::drawing::font::font_family ( ) const -> xtd::drawing::font_family

nodiscardnoexcept

Gets the xtd::drawing::font_family associated with this xtd::drawing::font.

Returns: The font_family associated with this Font.

Remarks: A font_family represents a group of fonts that have a similar font face, but may have different sizes and styles (for example, Arial, Times New Roman, and Verdana).

◆ gdi_char_set()

auto xtd::drawing::font::gdi_char_set ( ) const -> xtd::byte

nodiscardnoexcept

Gets a byte value that specifies the GDI character set that this xtd::drawing::font uses.

Returns: A byte value that specifies the GDI character set that this xtd::drawing::font uses. The default is 1.

Remarks

This property returns 1, unless a different character set is specified in the font(string, float, font_style, graphics_unit, xtd::byte) constructor. This property takes a value from the list defined in the Windows SDK header file WinGDI.h. The character sets and byte values are listed in the following table.

Character set	Value
ANSI	0
DEFAULT	1
SYMBOL	2
SHIFTJIS	128
HANGEUL	129
HANGUL	129
GB2312	134
CHINESEBIG5	136

◆ gdi_vertical_font()

auto xtd::drawing::font::gdi_vertical_font ( ) const -> bool

nodiscardnoexcept

Gets a Boolean value that indicates whether this xtd::drawing::font is derived from a GDI vertical font.

Returns: true if this xtd::drawing::font is derived from a GDI vertical font; otherwise, false.

Remarks: Use this property to determine if a font is compatible with native Win32 controls on non-Unicode platforms.; gdi_vertical_font only returns true if this font was created from a classic GDI font definition, like a LOGFONT or HFONT.

◆ handle()

auto xtd::drawing::font::handle ( ) const -> xtd::intptr

nodiscardnoexcept

Gets the window handle that the font is bound to.

Returns: An intptr that contains the window handle (hfont) of the font.

◆ height()

auto xtd::drawing::font::height ( ) const -> xtd::int32

nodiscardnoexcept

Gets the line spacing of this font.

Returns: The line spacing, in pixels, of this font.

Remarks: The line spacing is the vertical distance between the base lines of two consecutive lines of text. Thus, the line spacing includes the blank space between lines along with the height of the character itself.; If the unit property of the font is set to anything other than graphics_unit::pixel, the height (in pixels) is calculated using the vertical resolution of the screen display. For example, suppose the font unit is inches and the font size is 0.3. Also suppose that for the corresponding font family, the em-height is 2048 and the line spacing is 2355. For a screen display that has a vertical resolution of 96 dots per inch, you can calculate the height as follows:; 2355*(0.3/2048)*96 = 33.11719; The value returned by the get_height method would be 33.11719, and the value returned by the height property would be 34. The height property is the value returned by get_height, rounded up to the nearest integer.

◆ is_system_font()

auto xtd::drawing::font::is_system_font ( ) const -> bool

nodiscardnoexcept

Gets a value indicating whether the font is a member of xtd::drawing::system_fonts.

◆ italic()

auto xtd::drawing::font::italic ( ) const -> bool

nodiscardnoexcept

Gets a value that indicates whether this xtd::drawing::font is italic.

Returns: true if this xtd::drawing::font is italic; otherwise, false.
