CDC::GetStretchBltMode

Retrieves the current bitmap-stretching mode.

int GetStretchBltMode( ) const;

Return Value

The return value specifies the current bitmap-stretching mode — STRETCH_ANDSCANS, STRETCH_DELETESCANS, or STRETCH_ORSCANS — if the function is successful.

Remarks

The bitmap-stretching mode defines how information is removed from bitmaps that are stretched or compressed by the StretchBlt member function.

The STRETCH_ANDSCANS and STRETCH_ORSCANS modes are typically used to preserve foreground pixels in monochrome bitmaps. The STRETCH_DELETESCANS mode is typically used to preserve color in color bitmaps.
