IDWriteBitmapRenderTarget1::SetTextAntialiasMode method

Sets the current text antialiasing mode of the bitmap render target.

Syntax

virtual HRESULT SetTextAntialiasMode(
   DWRITE_TEXT_ANTIALIAS_MODE antialiasMode
) = 0;

Parameters

antialiasMode

Type: DWRITE_TEXT_ANTIALIAS_MODE

A DWRITE_TEXT_ANTIALIAS_MODE-typed value that specifies the antialiasing mode.

Return value

Type: HRESULT

Returns S_OK if successful, or E_INVALIDARG if the argument is not valid.

Remarks

The antialiasing mode of a newly-created bitmap render target defaults to DWRITE_TEXT_ANTIALIAS_MODE_CLEARTYPE. An app can change the antialiasing mode by calling SetTextAntialiasMode. For example, an app might specify DWRITE_TEXT_ANTIALIAS_MODE_GRAYSCALE for grayscale antialiasing when it renders text onto a transparent bitmap.
