IDWriteTextRenderer::DrawInlineObject Method

IDWriteTextLayout::Draw calls this application callback when it needs to draw an inline object.

Syntax

virtual HRESULT DrawInlineObject(
  void * clientDrawingContext,
  FLOAT  originX,
  FLOAT  originY,
  IDWriteInlineObject * inlineObject,
  BOOL  isSideways,
  BOOL  isRightToLeft,
  IUnknown * clientDrawingEffect
) = 0;

Parameter

• clientDrawingContext
  The application-defined drawing context passed to IDWriteTextLayout::Draw.

• originX
  X-coordinate at the top-left corner of the inline object.

• originY
  Y-coordinate at the top-left corner of the inline object.

• inlineObject
  The application-defined inline object set using IDWriteTextFormat::SetInlineObject.

• isSideways
  A Boolean flag that indicates whether the object's baseline runs alongside the baseline axis of the line.

• isRightToLeft
  A Boolean flag that indicates whether the object is in a right-to-left context, hinting that the drawing may want to mirror the normal image.

• clientDrawingEffect
  Application-defined drawing effects for the glyphs to render. Usually this argument represents effects such as the foreground brush filling the interior of a line.
