GPEBltParms (Windows Embedded CE 6.0)
1/6/2010
This structure controls blit operations for GPE and display drivers. Some of the members of GPEBltParms come from applications, while GPE calculates and sets the rest.

Members
- pBlt
Pointer to a function that will perform the blit operation.
- pDst
Pointer to the destination surface.
- pSrc
Pointer to the source surface.
- pMask
Pointer to the mask surface.
- pBrush
Pointer to the surface containing the brush.
- prclDst
Rectangle describing which portion of the destination surface to use.
- prclSrc
Rectangle describing which portion of the source surface to use.
- prclClip
Pointer to a clipping rectangle defined by the application.
- solidColor
Color to use for solid color fill blits. If the blit is a pattern fill, this should be set to –1.
- bltFlags
Blit operations to perform.
- rop4
ROP value for the blit.
- prclMask
Rectangle describing which portion of the mask surface to use.
- pptlBrush
Pointer to a POINTL brush.
- xPositive
Positive number if the x-coordinate of the display surface increases from left to right.
- yPositive
Positive number if the y-coordinate of the display surface increases from top to bottom.
- pLookup
Pointer to an array of color references which correspond to the palette entries. This is for source to palette color conversions.
- pConvert
Pointer to a function that handles color conversions.
- pColorConverter
Pointer to a color converter class.
- iMode
Mode to be used for StretchBlt. This value corresponds to the value set by SetStretchBltMode.
- blendFunction
Operation to use for AlphaBlend
- bltSig
64-bit encoding of other GPEBltParms members
