EMRALPHABLEND structure (wingdi.h)

The EMRALPHABLEND structure contains members for the AlphaBlend enhanced metafile record.

Syntax

typedef struct tagEMRALPHABLEND {
  EMR      emr;
  RECTL    rclBounds;
  LONG     xDest;
  LONG     yDest;
  LONG     cxDest;
  LONG     cyDest;
  DWORD    dwRop;
  LONG     xSrc;
  LONG     ySrc;
  XFORM    xformSrc;
  COLORREF crBkColorSrc;
  DWORD    iUsageSrc;
  DWORD    offBmiSrc;
  DWORD    cbBmiSrc;
  DWORD    offBitsSrc;
  DWORD    cbBitsSrc;
  LONG     cxSrc;
  LONG     cySrc;
} EMRALPHABLEND, *PEMRALPHABLEND;

Members

emr

The base structure for all record types.

rclBounds

Bounding rectangle, in device units.

xDest

The x coordinate, in logical units, of the upper-left corner of the destination rectangle.

yDest

The y coordinate, in logical units, of the upper-left corner of the destination rectangle.

cxDest

Logical width of the destination rectangle.

cyDest

Logical height of the destination rectangle.

dwRop

Stores the BLENDFUNCTION structure.

xSrc

Logical x coordinate of the upper-left corner of the source rectangle.

ySrc

Logical y coordinate of the upper-left corner of the source rectangle.

xformSrc

World-space to page-space transformation of the source device context.

crBkColorSrc

Background color (the RGB value) of the source device context. To make a COLORREF value, use the RGB macro.

iUsageSrc

Source bitmap information color table usage (DIB_RGB_COLORS).

offBmiSrc

Offset to the source BITMAPINFO structure.

cbBmiSrc

Size of the source BITMAPINFO structure.

offBitsSrc

Offset to the source bitmap bits.

cbBitsSrc

Size of the source bitmap bits.

cxSrc

Width of source rectangle in logical units.

cySrc

Height of the source rectangle in logical units.

Remarks

This structure is to be used during metafile playback.
