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
- The color to use for solid color fill blits. If the blit is a pattern fill, this should be seto to –1.
- bltFlags
- The blit operations to perform.
- rop4
- The ROP value for the blit.
- prclMask
- Rectangle describing which portion of the mask surface to use.
- pptlBrush
- A pointer to a POINTLbrush.
- xPositive
- This value contains a positive number if the x-coordinate of the display surface increases from left to right.
- yPositive
- This value contains a positive number if the y-coordinate of the display surface increases from top to bottom.
- pLookup
- For src=palette color conversions, this member is a pointer to an array of color references which correspond to the pallete entries.
- pConvert
- A pointer to a function which handles color conversions.
- pColorConverter
- A pointer to a color converter class.
Requirements
Runs on Versions Defined in Include Link to Windows CE OS 1.0 and later gpe.h
