A server interface for font management and text rendering. [TextServer] is the API backend for managing fonts and rendering text. Creates a new, empty font cache entry resource. To free the resulting resource, use the [method free_rid] method. Creates a new variation existing font which is reusing the same glyph cache and font data. To free the resulting resource, use the [method free_rid] method. Creates new buffer for complex text layout, with the given [param direction] and [param orientation]. To free the resulting buffer, use [method free_rid] method. [b]Note:[/b] Direction is ignored if server does not support [constant FEATURE_BIDI_LAYOUT] feature (supported by [TextServerAdvanced]).

Sets kerning for the pair of glyphs. Adds override for [method font_is_language_supported]. Sets the width of the range around the shape between the minimum and maximum representable signed distance. Sets source font size used to generate MSDF textures. If set to [code]true[/code], glyphs of all sizes are rendered using single multichannel signed distance field generated from the dynamic font vector data. MSDF rendering allows displaying the font at any scaling factor without blurriness, and without incurring a CPU cost when the font size changes (since the font no longer needs to be rasterized on the CPU). As a downside, font hinting is not available with MSDF. The lack of font hinting may result in less crisp and less readable fonts at small sizes. [b]Note:[/b] MSDF font rendering does not render glyphs with overlapping shapes correctly. Overlapping shapes are not valid per the OpenType standard, but are still commonly found in many font files, especially those converted by Google Fonts. To avoid issues with overlapping glyphs, consider downloading the font file directly from the type foundry instead of relying on Google Fonts. Sets the font family name.

A percentage value between [code]50%[/code] and [code]200%[/code]. [b]Note:[/b] This value is used for font matching only and will not affect font rendering. Use [method font_set_face_index], [method font_set_variation_coordinates], or [method font_set_transform] instead. Sets the font style flags, see [enum FontStyle]. [b]Note:[/b] This value is used for font matching only and will not affect font rendering.

Sets thickness of the underline in pixels. Sets variation coordinates for the specified font cache entry. See [method font_supported_variation_list] for more info. Sets 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]. [b]Note:[/b] This value is used for font matching only and will not affect font rendering.

Returns [code]true[/code] if [param string] is a valid identifier. If the text server supports the [constant FEATURE_UNICODE_IDENTIFIERS] feature, a valid identifier must: - Conform to normalization form C. - Begin with a Unicode character of class XID_Start or [code]"_"[/code]. - May contain Unicode characters of class XID_Continue in the other positions. - Use UAX #31 recommended scripts only (mixed scripts are allowed). If the [constant FEATURE_UNICODE_IDENTIFIERS] feature is not supported, a valid identifier must: - Begin with a Unicode character of class XID_Start or [code]"_"[/code]. - May contain Unicode characters of class XID_Continue in the other positions.

Converts OpenType tag to readable feature, variation, script or language name. Font glyphs are rasterized as 1-bit bitmaps. Font glyphs are rasterized as 8-bit grayscale anti-aliased bitmaps. Font glyphs are rasterized for LCD screens. LCD subpixel layout is determined by the value of [code]gui/theme/lcd_subpixel_layout[/code] project settings. LCD subpixel anti-aliasing mode is suitable only for rendering horizontal, unscaled text in 2D. Unknown or unsupported subpixel layout, LCD subpixel antialiasing is disabled. Horizontal RGB subpixel layout. Horizontal BGR subpixel layout. Vertical RGB subpixel layout. Vertical BGR subpixel layout. Text direction is determined based on contents and current locale. Text is written from left to right. Text is written from right to left. Text writing direction is the same as base string writing direction. Used for BiDi override only. Text is written horizontally. Left to right text is written vertically from top to bottom. Right to left text is written vertically from bottom to top. Do not justify text. Justify text by adding and removing kashidas. Justify text by changing width of the spaces between the words. Remove trailing and leading spaces from the justified text. Only apply justification to the part of the text after the last tab. Apply justification to the trimmed line with ellipsis. Do not apply justification to the last line of the paragraph. Do not apply justification to the last line of the paragraph with visible characters (takes precedence over [constant JUSTIFICATION_SKIP_LAST_LINE]). Always apply justification to the paragraphs with a single line ([constant JUSTIFICATION_SKIP_LAST_LINE] and [constant JUSTIFICATION_SKIP_LAST_LINE_WITH_VISIBLE_CHARS] are ignored). Autowrap is disabled. Wraps the text inside the node's bounding rectangle by allowing to break lines at arbitrary positions, which is useful when very limited space is available. Wraps the text inside the node's bounding rectangle by soft-breaking between words. Behaves similarly to [constant AUTOWRAP_WORD], but force-breaks a word if that single word does not fit in one line. Do not break the line. Break the line at the line mandatory break characters (e.g. [code]"\n"[/code]). Break the line between the words. Break the line between any unconnected graphemes. Should be used only in conjunction with [constant BREAK_WORD_BOUND], break the line between any unconnected graphemes, if it's impossible to break it between the words. Remove edge spaces from the broken line segments. Trims text before the shaping. e.g, increasing [member Label.visible_characters] or [member RichTextLabel.visible_characters] value is visually identical to typing the text. Displays glyphs that are mapped to the first [member Label.visible_characters] or [member RichTextLabel.visible_characters] characters from the beginning of the text. Displays [member Label.visible_ratio] or [member RichTextLabel.visible_ratio] glyphs, starting from the left or from the right, depending on [member Control.layout_direction] value. Displays [member Label.visible_ratio] or [member RichTextLabel.visible_ratio] glyphs, starting from the left. Displays [member Label.visible_ratio] or [member RichTextLabel.visible_ratio] glyphs, starting from the right. No text trimming is performed. Trims the text per character. Trims the text per word. Trims the text per character and adds an ellipsis to indicate that parts are hidden. Trims the text per word and adds an ellipsis to indicate that parts are hidden. No trimming is performed. Trims the text when it exceeds the given width. Trims the text per word instead of per grapheme. Determines whether an ellipsis should be added at the end of the text. Determines whether the ellipsis at the end of the text is enforced and may not be hidden. Grapheme is supported by the font, and can be drawn. Grapheme is part of right-to-left or bottom-to-top run. Grapheme is not part of source text, it was added by justification process. Grapheme is whitespace. Grapheme is mandatory break point (e.g. [code]"\n"[/code]). Grapheme is optional break point (e.g. space). Grapheme is the tabulation character. Grapheme is kashida. Grapheme is punctuation character. Grapheme is underscore character. Grapheme is connected to the previous grapheme. Breaking line before this grapheme is not safe. It is safe to insert a U+0640 before this grapheme for elongation. Grapheme is an object replacement character for the embedded object. Disables font hinting (smoother but less crisp). Use the light font hinting mode. Use the default font hinting mode (crisper but less smooth). [b]Note:[/b] This hinting mode changes both horizontal and vertical glyph metrics. If applied to monospace font, some glyphs might have different width. Glyph horizontal position is rounded to the whole pixel size, each glyph is rasterized once. Glyph horizontal position is rounded based on font size. - To one quarter of the pixel size if font size is smaller or equal to [constant SUBPIXEL_POSITIONING_ONE_QUARTER_MAX_SIZE]. - To one half of the pixel size if font size is smaller or equal to [constant SUBPIXEL_POSITIONING_ONE_HALF_MAX_SIZE]. - To the whole pixel size for larger fonts. Glyph horizontal position is rounded to one half of the pixel size, each glyph is rasterized up to two times. Glyph horizontal position is rounded to one quarter of the pixel size, each glyph is rasterized up to four times. Maximum font size which will use one half of the pixel subpixel positioning in [constant SUBPIXEL_POSITIONING_AUTO] mode.
