Detailed Description

A Subset represents a subset of the glyphs of a GlyphSequence for the purpose of culling when rendering. Different Subset values from the same GlyphSequence are guaranteed to have disjoint glyphs.

Member Function Documentation

◆ attributes_and_indices()

void fastuidraw::GlyphSequence::Subset::attributes_and_indices	(	GlyphRenderer	render,
		c_array< const PainterAttribute > *	out_attributes,
		c_array< const PainterIndex > *	out_indices
	)

Given a GlyphRenderer, returns Painter Attribute and PainterIndex data for specified GlyphRenderer value. The attribute data and index is generated by the GlyphAttributePacker as returned by parents GlyphSequence::attribute_packer(). The data is constructed lazily on demand.

Parameters

render	GlyphRenderer how to render the glyphs of this Subset
out_attributes	location to which to write the array of the attributes to render the glyphs
out_indices	location to which to write the array of the indices to render the glyphs

◆ bounding_box()

bool fastuidraw::GlyphSequence::Subset::bounding_box ( Rect * out_bb_box )

Gives the bounding box of the glyphs of this Subset object. A return value of false indicates that the bounding box is empty.

Parameters

out_bb_box location to which to write the bounding box

◆ glyphs()

c_array<const unsigned int> fastuidraw::GlyphSequence::Subset::glyphs ( void )

Returns an array of index values to pass to GlyphSequence::add_glyph() of the glyphs of this Subset.

◆ path()

const Path& fastuidraw::GlyphSequence::Subset::path ( void )

Returns the Path made from the bounding box of the Subset.
