EMRMASKBLT
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.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
