Sets the bitmap stretching mode in the specified device context
#include <WinAPIGdi.au3>
_WinAPI_SetStretchBltMode ( $hDC, $iMode )
| $hDC | Handle to the device context. |
| $iMode | The stretching mode. This parameter can be one of the following values. $BLACKONWHITE $COLORONCOLOR $HALFTONE $WHITEONBLACK $STRETCH_ANDSCANS $STRETCH_DELETESCANS $STRETCH_HALFTONE $STRETCH_ORSCANS |
| Success: | The previous stretching mode. |
| Failure: | 0 and sets the @error flag to non-zero, @extended may contain ERROR_INVALID_PARAMETER. |
The $BLACKONWHITE ($STRETCH_ANDSCANS) and $WHITEONBLACK ($STRETCH_ORSCANS) modes are typically used to
preserve foreground pixels in monochrome bitmaps. The $COLORONCOLOR ($STRETCH_DELETESCANS) mode is typically
used to preserve color in color bitmaps. The $HALFTONE ($STRETCH_HALFTONE) mode is slower and requires more
processing of the source image than the other three modes; but produces higher quality images.
