DOC: Incorrect iModes Parameter to DDI StretchBlt Functions

ID: Q140674

The information in this article applies to:

Microsoft Win32 Device Driver Kit (DDK) for Windows NT, versions 3.5, 3.51

SUMMARY

There is an error in the online documentation for the iModes parameter to the XxxStretchBlt and XxxPlgBlt functions.

These the XxxStretchBlt and XxxPlgBlt functions are used for both Win32 display drivers and Win32 printer drivers. The iModes parameter defines how source pixels are combined to get output pixels.

The documentation states that the ULONG iModes parameter should be one of the following defined values: SB_OR, SB_AND, SB_IGNORE, or SB_HALFTONE. Actually, these values are not defined. The iModes parameter should be replaced with one of the following values that are defined in Sdk\Include\Wingdi.h:


   Original      Replacement
   --------------------------
   SB_OR         WHITEONBLACK
   SB_AND        BLACKONWHITE
   SB_IGNORE     COLORONCOLOR
   SB_HALFTONE   HALFTONE

This documentation error has been corrected in the Win32 DDK version 4.0 online documentation.
