[−][src]Module azul_text_layout::text_layout

Contains functions for breaking a string into words, calculate the positions of words / lines and do glyph positioning

Structs

ClusterInfo	Info about what cluster a certain glyph belongs to.
ClusterIterator	Iterator over glyphs that returns information about the cluster that this glyph belongs to. Returned by the `ScaledWord::cluster_iter()` function.
FontMetrics
GlyphInfo
GlyphInstance
GlyphPosition
InlineTextLayout
LayoutedGlyphs	Returns the layouted glyph instances
ResolvedTextLayoutOptions	Same as `TextLayoutOptions`, but with the widths / heights of the `PixelValue`s resolved to regular f32s (because `letter_spacing`, `word_spacing`, etc. may be %-based value)
ScaledWord	Word that is scaled (to a font / font instance), but not yet positioned
ScaledWords	A paragraph of words that are shaped and scaled (* but not yet layouted / positioned*!) according to their final size in pixels.
TextLayoutOptions	Layout options that can impact the flow of word positions
Word	Section of a certain type
WordPositions	Stores the positions of the vertically laid out texts
Words	Text broken up into `Tab`, `Word()`, `Return` characters

LineCaretIntersection
TextOverflow	Whether the text overflows the parent rectangle, and if yes, by how many pixels, necessary for determining if / how to show a scrollbar + aligning / centering text.
WordType	Either a white-space delimited word, tab or return character

advance_caret
caret_intersects_with_holes	Check if the caret intersects with any holes and if yes, if the cursor should move to a new line.
get_layouted_glyphs
get_line_y_position	For a given line number (NOTE: 0-indexed!), calculates the Y position of the bottom left corner
position_words	Positions the words on the screen (does not layout any glyph positions!), necessary for estimating the intrinsic width + height of the text content.
split_text_into_words	Splits the text by whitespace into logical units (word, tab, return, whitespace).
word_item_is_return
word_positions_to_inline_text_layout	Returns the (left-aligned!) bounding boxes of the indidividual text lines
words_to_scaled_words	Takes a text broken into semantic items and a font instance and scales the font accordingly.
