EMRMASKBLT  EC6LTK 

The EMRMASKBLT structure contains members for the MaskBlt137O3AS 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.2PXNH 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.2PXNH 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.
