Parameters

characterRange

Type: Microsoft.Graphics.Canvas.TextCanvasCharacterRange

fontFace

Type: Microsoft.Graphics.Canvas.TextCanvasFontFace

fontSize

Type: SystemSingle

script

Type: Microsoft.Graphics.Canvas.TextCanvasAnalyzedScript

clusterMapIndicesElements

Type: SystemInt32

glyphShapingResultsElements

Type: Microsoft.Graphics.Canvas.TextCanvasGlyphShaping

Return Value

This is the place to start when performing justification on custom text layouts. The order of things is to:

• Split up your text spans into glyph runs.
• Fit your glyph runs into the layout boxes. Perform word wrapping if desired.
• For each glyph run, call GetJustificationOpportunities to obtain an array of CanvasJustificationOpportunity.
• Pass an array of all CanvasJustificationOpportunity's for each layout box to ApplyJustificationOpportunities(Single, CanvasJustificationOpportunity, CanvasGlyph).
• Assign the justified glyph data back into your app's glyph runs.
• Optionally, call AddGlyphsAfterJustification(CanvasFontFace, Single, CanvasAnalyzedScript, Int32, CanvasGlyph, CanvasGlyph, CanvasGlyphShaping, Int32) to insert extra justification glyphs- for example, if you would like to use Arabic kashida.
• Draw the glyph runs.

If a null font face is specified, the default font face will be used.
