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.

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. 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. 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.percent_visible] or [member RichTextLabel.percent_visible] glyphs, starting from the left or from the right, depending on [member Control.layout_direction] value.

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. Disables font hinting (smoother but less crisp). Use the light font hinting mode. Use the default font hinting mode (crisper but less smooth). 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.
