class | Line |
A visual run is text which is in the same font, script, and direction. The text is represented by an array of LEGlyphIDs
, an array of (x, y) glyph positions and a table which maps indices into the glyph array to indices into the original character array which was used to create the paragraph.
These objects are only created by ParagraphLayout::Line
objects, so their constructors and destructors are private.

|
Get the glyph-to-character map for this visual run. This maps the indices into the glyph array to indices into the character array used to create the paragraph.

A convenience method which returns the leading value for the font associated with this run.
Definition at line 700 of file ParagraphLayout.h. References LEFontInstance::getLeading(). |
|
Get the (x, y) positions of the glyphs in the visual run. To simplify storage management, the x and y positions are stored in a single array with the x positions at even offsets in the array and the corresponding y position in the following odd offset. There is an extra (x, y) pair at the end of the array which represents the advance of the final glyph in the run.
