EMRMASKBLT info Overview Group

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: 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 destination rectangle
cyDest: Logical height of 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.
iUsageSrc: Value of the bmiColors member of the source BITMAPINFO structure. The iUsageSrc member can be either the DIB_PAL_COLORS, DIB_PAL_INDICES, 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.
