Module nannou::text [−][src]
Expand description
Text layout logic.
Currently, this crate is used primarily by the draw.text()
API but will also play an
important role in future GUI work.
Re-exports
pub use self::layout::Layout;
Modules
Logic related to the positioning of the cursor within text.
The font::Id
and font::Map
types.
Logic and types specific to individual glyph layout.
Items related to the styling of text.
Text handling logic related to individual lines of text.
Re-exported RustType geometric types.
Structs
A context for building some Text.
A single glyph of a font. this may either be a thin wrapper referring to the font and the glyph id, or it may be a standalone glyph that owns the data needed by it.
An implementation of a dynamic GPU glyph cache. See the module documentation for more information.
Represents a glyph identifier for a particular font. This identifier will not necessarily correspond to the correct glyph in a font other than the one that it was obtained from.
An iterator yielding each line within the given text
as a new &str
, where the start and end
indices into each line are provided by the given iterator.
Defines the size of a rendered face of a font, in pixels, horizontally and
vertically. A vertical scale of y
pixels means that the distance betwen
the ascent and descent lines (see VMetrics
) of the face will be y
pixels. If x
and y
are equal the scaling is uniform. Non-uniform scaling
by a factor f in the horizontal direction is achieved by setting x
equal
to f times y
.
A glyph augmented with scaling information. You can query such a glyph for information that depends on the scale of the glyph.
An instance of some multi-line text and its layout.
An alias for the line rect iterator yielded by Text::line_rects
.
Enums
Alignment along an axis.
A type used for referring to typographic alignment of Text
.
The way in which text should wrap around the width.
Functions
Determine the exact height of a block of text.
Converts the given font size in “points” to its font size in pixels. This is useful for when the font size is not an integer.
Converts the given font size in “points” to a uniform rusttype::Scale
.
This is useful for when the font size is not an integer.
Determine the total height of a block of text with the given number of lines, font size and
line_spacing
(the space that separates each line of text).
Produce an iterator yielding each line within the given text
as a new &str
, where the
start and end indices into each line are provided by the given iterator.
The position offset required to shift the associated text into the given bounding rectangle.
Converts the given font size in “points” to its font size in pixels.
Converts the given font size in “points” to a uniform rusttype::Scale
.
Produce the position of each glyph ready for the rusttype glyph cache.
Begin building a Text instance.
