Abstract base class for fonts and font variations.
Abstract base class for different font types. It has methods for drawing text and font character introspection.
Draw a single Unicode character [param char] into a canvas item using the font, at a given position, with [param modulate] color. [param pos] specifies the baseline, not the top. To draw from the top, [i]ascent[/i] must be added to the Y axis.
[b]Note:[/b] Do not use this function to draw strings character by character, use [method draw_string] or [TextLine] instead.
Draw a single Unicode character [param char] outline into a canvas item using the font, at a given position, with [param modulate] color and [param size] outline size. [param pos] specifies the baseline, not the top. To draw from the top, [i]ascent[/i] must be added to the Y axis.
[b]Note:[/b] Do not use this function to draw strings character by character, use [method draw_string] or [TextLine] instead.
Breaks [param text] into lines using rules specified by [param brk_flags] and draws it into a canvas item using the font, at a given position, with [param modulate] color, optionally clipping the width and aligning horizontally. [param pos] specifies the baseline of the first line, not the top. To draw from the top, [i]ascent[/i] must be added to the Y axis.
See also [method CanvasItem.draw_multiline_string].
Breaks [param text] to the lines using rules specified by [param brk_flags] and draws text outline into a canvas item using the font, at a given position, with [param modulate] color and [param size] outline size, optionally clipping the width and aligning horizontally. [param pos] specifies the baseline of the first line, not the top. To draw from the top, [i]ascent[/i] must be added to the Y axis.
See also [method CanvasItem.draw_multiline_string_outline].
Draw [param text] into a canvas item using the font, at a given position, with [param modulate] color, optionally clipping the width and aligning horizontally. [param pos] specifies the baseline, not the top. To draw from the top, [i]ascent[/i] must be added to the Y axis.
See also [method CanvasItem.draw_string].
Draw [param text] outline into a canvas item using the font, at a given position, with [param modulate] color and [param size] outline size, optionally clipping the width and aligning horizontally. [param pos] specifies the baseline, not the top. To draw from the top, [i]ascent[/i] must be added to the Y axis.
See also [method CanvasItem.draw_string_outline].
Returns [TextServer] RID of the font cache for specific variation.
Returns the average font ascent (number of pixels above the baseline).
[b]Note:[/b] Real ascent of the string is context-dependent and can be significantly different from the value returned by this function. Use it only as rough estimate (e.g. as the ascent of empty line).
Returns the size of a character. Does not take kerning into account.
[b]Note:[/b] Do not use this function to calculate width of the string character by character, use [method get_string_size] or [TextLine] instead. The height returned is the font height (see also [method get_height]) and has no relation to the glyph height.
Returns the average font descent (number of pixels below the baseline).
[b]Note:[/b] Real descent of the string is context-dependent and can be significantly different from the value returned by this function. Use it only as rough estimate (e.g. as the descent of empty line).
Returns number of faces in the TrueType / OpenType collection.
Returns font family name.
Returns font stretch amount, compared to a normal width. A percentage value between [code]50%[/code] and [code]200%[/code].
Returns font style flags, see [enum TextServer.FontStyle].
Returns font style name.
Returns weight (boldness) of the font. A value in the [code]100...999[/code] range, normal font weight is [code]400[/code], bold font weight is [code]700[/code].
Returns the total average font height (ascent plus descent) in pixels.
[b]Note:[/b] Real height of the string is context-dependent and can be significantly different from the value returned by this function. Use it only as rough estimate (e.g. as the height of empty line).
Returns the size of a bounding box of a string broken into the lines, taking kerning and advance into account.
See also [method draw_multiline_string].
Returns a set of OpenType feature tags. More info: [url=https://docs.microsoft.com/en-us/typography/opentype/spec/featuretags]OpenType feature tags[/url].
Returns [Dictionary] with OpenType font name strings (localized font names, version, description, license information, sample text, etc.).
Returns [Array] of valid [Font] [RID]s, which can be passed to the [TextServer] methods.
Returns the spacing for the given [code]type[/code] (see [enum TextServer.SpacingType]).
Returns the size of a bounding box of a single-line string, taking kerning, advance and subpixel positioning into account. See also [method get_multiline_string_size] and [method draw_string].
For example, to get the string size as displayed by a single-line Label, use:
[codeblocks]
[gdscript]
var string_size = $Label.get_theme_font("font").get_string_size($Label.text, HORIZONTAL_ALIGNMENT_LEFT, -1, $Label.get_theme_font_size("font_size"))
[/gdscript]
[csharp]
Label label = GetNode<Label>("Label");
Vector2 stringSize = label.GetThemeFont("font").GetStringSize(label.Text, HorizontalAlignment.Left, -1, label.GetThemeFontSize("font_size"));
[/csharp]
[/codeblocks]
[b]Note:[/b] Since kerning, advance and subpixel positioning are taken into account by [method get_string_size], using separate [method get_string_size] calls on substrings of a string then adding the results together will return a different result compared to using a single [method get_string_size] call on the full string.
[b]Note:[/b] Real height of the string is context-dependent and can be significantly different from the value returned by [method get_height].
Returns a string containing all the characters available in the font.
If a given character is included in more than one font data source, it appears only once in the returned string.
Returns list of OpenType features supported by font.
Returns list of supported [url=https://docs.microsoft.com/en-us/typography/opentype/spec/dvaraxisreg]variation coordinates[/url], each coordinate is returned as [code]tag: Vector3i(min_value,max_value,default_value)[/code].
Font variations allow for continuous change of glyph characteristics along some given design axis, such as weight, width or slant.
To print available variation axes of a variable font:
[codeblock]
var fv = FontVariation.new()
fv.base_font = load("res://RobotoFlex.ttf")
var variation_list = fv.get_supported_variation_list()
for tag in variation_list:
var name = TextServerManager.get_primary_interface().tag_to_name(tag)
var values = variation_list[tag]
print("variation axis: %s (%d)\n\tmin, max, default: %s" % [name, tag, values])
[/codeblock]
[b]Note:[/b] To set and get variation coordinates of a [FontVariation], use [member FontVariation.variation_opentype].
Returns average pixel offset of the underline below the baseline.
[b]Note:[/b] Real underline position of the string is context-dependent and can be significantly different from the value returned by this function. Use it only as rough estimate.
Returns average thickness of the underline.
[b]Note:[/b] Real underline thickness of the string is context-dependent and can be significantly different from the value returned by this function. Use it only as rough estimate.
Returns [code]true[/code] if a Unicode [param char] is available in the font.
Returns [code]true[/code], if font supports given language ([url=https://en.wikipedia.org/wiki/ISO_639-1]ISO 639[/url] code).
Returns [code]true[/code], if font supports given script ([url=https://en.wikipedia.org/wiki/ISO_15924]ISO 15924[/url] code).
Sets LRU cache capacity for [code]draw_*[/code] methods.
Array of fallback [Font]s to use as a substitute if a glyph is not found in this current [Font].
If this array is empty in a [FontVariation], the [member FontVariation.base_font]'s fallbacks are used instead.
