EMRMASKBLT structure (wingdi.h)
The EMRMASKBLT structure contains members for the MaskBlt enhanced metafile record. Note that graphics device interface (GDI) converts the device-dependent bitmap into a device-independent bitmap (DIB) before storing it in the metafile record.

Members
emr
The base structure for all record types.
rclBounds
Bounding rectangle, in device units.
xDest
Logical x-coordinate of the upper-left corner of the destination rectangle.
yDest
Logical y-coordinate of the upper-left corner of the destination rectangle.
cxDest
Logical width of the destination rectangle.
cyDest
Logical height of the destination rectangle.
dwRop
Raster-operation code. These codes define how the color data of the source rectangle is to be combined with the color data of the destination rectangle to achieve the final color.
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
Value of the bmiColors member of the source BITMAPINFO structure. The iUsageSrc member can be either the DIB_PAL_COLORS or DIB_RGB_COLORS value.
offBmiSrc
Offset to source BITMAPINFO structure.
cbBmiSrc
Size of source BITMAPINFO structure.
offBitsSrc
Offset to source bitmap bits.
cbBitsSrc
Size of source bitmap bits.
xMask
Horizontal pixel offset into mask bitmap.
yMask
Vertical pixel offset into mask bitmap.
iUsageMask
Value of the bmiColors member of the mask BITMAPINFO structure.
offBmiMask
Offset to mask BITMAPINFO structure.
cbBmiMask
Size of mask BITMAPINFO structure.
offBitsMask
Offset to mask bitmap bits.
cbBitsMask
Size of mask bitmap bits.
