TIECanvas.SmoothingMode

Declaration

property SmoothingMode: TIECanvasSmoothingMode;

Description

Specify whether smoothing (antialiasing) is applied to lines and curves and the edges of filled areas.

iesmDefault, iesmBestPerformance and iesmNone specify that smoothing is not applied.
iesmBestRenderingQuality, iesmAntialias specify that smoothing is applied using an 8x4 box filter.
iesmAntialias8x8 specifies that smoothing is applied using an 8x8 box filter.

GDI+ Method: GdipSetSmoothingMode

Default: iesmBestRenderingQuality
