IDWriteFontFace::GetRecommendedRenderingMode method (dwrite.h)

  • Article

Determines the recommended rendering mode for the font, using the specified size and rendering parameters.

Syntax

HRESULT GetRecommendedRenderingMode(
        FLOAT                  emSize,
        FLOAT                  pixelsPerDip,
        DWRITE_MEASURING_MODE  measuringMode,
        IDWriteRenderingParams *renderingParams,
  [out] DWRITE_RENDERING_MODE  *renderingMode
);

Parameters

emSize

Type: FLOAT

The logical size of the font in DIP units. A DIP ("device-independent pixel") equals 1/96 inch.

pixelsPerDip

Type: FLOAT

The number of physical pixels per DIP. For example, if the DPI of the rendering surface is 96, this value is 1.0f. If the DPI is 120, this value is 120.0f/96.

measuringMode

Type: DWRITE_MEASURING_MODE

The measuring method that will be used for glyphs in the font. Renderer implementations may choose different rendering modes for different measuring methods, for example:

renderingParams

Type: IDWriteRenderingParams*

A pointer to an object that contains rendering settings such as gamma level, enhanced contrast, and ClearType level. This parameter is necessary in case the rendering parameters object overrides the rendering mode.

[out] renderingMode

Type: DWRITE_RENDERING_MODE*

When this method returns, contains a value that indicates the recommended rendering mode to use.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
