Egenskapsvärde

Ett BrushMappingMode värde som anger hur toningsborstens positioneringskoordinater tolkas. Standardvärdet är RelativeToBoundingBox.

Exempel

I följande exempel visas hur du använder MappingMode egenskapen för att ange vilket koordinatsystem som ska användas för StartPoint och EndPoint för toningen.

Värdet anger att toningsborstens koordinater uttrycks med hjälp av Absolute enhetsoberoende bildpunkter.
