D2D1_OPACITY_MASK_CONTENT enumeration (d2d1.h)

  • Article

Describes whether an opacity mask contains graphics or text. Direct2D uses this information to determine which gamma space to use when blending the opacity mask.

Syntax

typedef enum D2D1_OPACITY_MASK_CONTENT {
  D2D1_OPACITY_MASK_CONTENT_GRAPHICS = 0,
  D2D1_OPACITY_MASK_CONTENT_TEXT_NATURAL = 1,
  D2D1_OPACITY_MASK_CONTENT_TEXT_GDI_COMPATIBLE = 2,
  D2D1_OPACITY_MASK_CONTENT_FORCE_DWORD = 0xffffffff
} ;

Constants

 
D2D1_OPACITY_MASK_CONTENT_GRAPHICS
Value: 0
The opacity mask contains graphics. The opacity mask is blended in the gamma 2.2 color space.
D2D1_OPACITY_MASK_CONTENT_TEXT_NATURAL
Value: 1
The opacity mask contains non-GDI text. The gamma space used for blending is obtained from the render target's text rendering parameters. (ID2D1RenderTarget::SetTextRenderingParams).
D2D1_OPACITY_MASK_CONTENT_TEXT_GDI_COMPATIBLE
Value: 2
The opacity mask contains text rendered using the GDI-compatible rendering mode. The opacity mask is blended using the gamma for GDI rendering.
D2D1_OPACITY_MASK_CONTENT_FORCE_DWORD
Value: 0xffffffff
