Members

emr

Base structure for all record types.

rclbounds

Bounding rectangle, in device units.

xDest

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

yDest

Specifies 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.

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.

cySrc

Height of the source rectangle.

Remarks

This structure is to be used during metafile playback.
