SystemFont

继承: Font < Resource < RefCounted < Object

A font loaded from a system font. Falls back to a default theme font if not implemented on the host OS.

描述

SystemFont loads a font from a system font with the first matching name from font_names.

It will attempt to match font style, but it's not guaranteed.

The returned font might be part of a font collection or be a variable font with OpenType "weight", "width" and/or "italic" features set.

You can create FontVariation of the system font for precise control over its features.

Note: This class is implemented on iOS, Linux, macOS and Windows, on other platforms it will fallback to default theme font.

属性


属性说明

bool allow_system_fallback = true

  • void set_allow_system_fallback ( value: bool )
  • bool is_allow_system_fallback ( )

If set to true, system fonts can be automatically used as fallbacks.


FontAntialiasing antialiasing = 1

Font anti-aliasing mode.


bool disable_embedded_bitmaps = true

  • void set_disable_embedded_bitmaps ( value: bool )
  • bool get_disable_embedded_bitmaps ( )

If set to true, embedded font bitmap loading is disabled (bitmap-only and color fonts ignore this property).


bool font_italic = false

  • void set_font_italic ( value: bool )
  • bool get_font_italic ( )

If set to true, italic or oblique font is preferred.


PackedStringArray font_names = PackedStringArray()

Array of font family names to search, first matching font found is used.

Note: The returned array is copied and any changes to it will not update the original property value. See PackedStringArray for more details.


int font_stretch = 100

  • void set_font_stretch ( value: int )
  • int get_font_stretch ( )

Preferred font stretch amount, compared to a normal width. A percentage value between 50% and 200%.


int font_weight = 400

  • void set_font_weight ( value: int )
  • int get_font_weight ( )

Preferred weight (boldness) of the font. A value in the 100...999 range, normal font weight is 400, bold font weight is 700.


bool force_autohinter = false

  • void set_force_autohinter ( value: bool )
  • bool is_force_autohinter ( )

If set to true, auto-hinting is supported and preferred over font built-in hinting.


bool generate_mipmaps = false

  • void set_generate_mipmaps ( value: bool )
  • bool get_generate_mipmaps ( )

If set to true, generate mipmaps for the font textures.


Hinting hinting = 1

Font hinting mode.


int msdf_pixel_range = 16

  • void set_msdf_pixel_range ( value: int )
  • int get_msdf_pixel_range ( )

The width of the range around the shape between the minimum and maximum representable signed distance. If using font outlines, msdf_pixel_range must be set to at least twice the size of the largest font outline. The default msdf_pixel_range value of 16 allows outline sizes up to 8 to look correct.


int msdf_size = 48

  • void set_msdf_size ( value: int )
  • int get_msdf_size ( )

Source font size used to generate MSDF textures. Higher values allow for more precision, but are slower to render and require more memory. Only increase this value if you notice a visible lack of precision in glyph rendering.


bool multichannel_signed_distance_field = false

  • void set_multichannel_signed_distance_field ( value: bool )
  • bool is_multichannel_signed_distance_field ( )

If set to true, glyphs of all sizes are rendered using single multichannel signed distance field generated from the dynamic font vector data.


float oversampling = 0.0

  • void set_oversampling ( value: float )
  • float get_oversampling ( )

Font oversampling factor, if set to 0.0 global oversampling factor is used instead.


SubpixelPositioning subpixel_positioning = 1

Font glyph subpixel positioning mode. Subpixel positioning provides shaper text and better kerning for smaller font sizes, at the cost of memory usage and font rasterization speed. Use TextServer.SUBPIXEL_POSITIONING_AUTO to automatically enable it based on the font size.
