解説

To draw text with this method, a textLayout object needs to be created by the application using C1.Util.DX.DirectWrite.Factory.CreateTextLayout(System.String,System.Int32,C1.Util.DX.DirectWrite.TextFormat,System.Single,System.Single,C1.Util.DX.DirectWrite.TextLayout). After the textLayout object is obtained, the application calls the IDWriteTextLayout::Draw method to draw the text, decorations, and inline objects. The actual drawing is done through the callback interface passed in as the textRenderer argument; there, the corresponding DrawGlyphRun API is called.
