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;

} 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.
