short Escape(hDC, SET_MIRROR_MODE, sizeof(WORD),lpInData, (LPSTR)NULL)
This escape sets the current mirror mode. The mirror mode produces mirror images along the horizontal axis, the vertical axis, or both axes.
To produce a mirror image of a given page, the application issues the SET_MIRROR_MODE escape before drawing the first primitive to be mirrored. When the last mirrored primitive has been drawn, the application issues a second SET_MIRROR_MODE escape to turn off mirroring.
| Parameter | Type/Description |
| hDC | HDC Identifies the device context. | ||
| lpMirrorMode | LPINT Points to a short integer that specifies the mirror mode. It must be one of the following values: | ||
| Value | Meaning | ||
| MIRROR_NONE (0) | Disable mirroring. | ||
| MIRROR_HORIZONTAL (1) | Mirror along the horizontal axis. | ||
| MIRROR_VERTICAL (2) | Mirror along the ver-tical axis. | ||
| MIRROR_BOTH (3) | Mirror along both axes. | ||
The return value is the previous mirror mode.
The default mirror mode is MIRROR_NONE.
Mirrored and unmirrored output can be mixed on a page. This allows the application to produce mirrored output with unmirrored page labels, crop marks, and so on.
