## Detailed Description

EMF Scale Viewport Extents (ex)

The viewport extent is the device coordinate (i.e. pixels) size of the viewport. Scale the viewport extents by the ratios of the given values. (OpenOffice accepts this, but not SETVIEWPORTEXT(?))

## Constructor & Destructor Documentation

### EMF::EMRSCALEVIEWPORTEXTEX::EMRSCALEVIEWPORTEXTEX (LONG x\_num, LONG x\_den, LONG y\_num, LONG y\_den)` [inline]`

**Parameters**

*x\_num* numerator of x scale \
 *x\_den* denominator of x scale \
 *y\_num* numerator of y scale \
 *y\_den* denominator of y scale

### EMF::EMRSCALEVIEWPORTEXTEX::EMRSCALEVIEWPORTEXTEX (DATASTREAM & ds)` [inline]`

Construct a ScaleViewportExtEx record from the input stream.

**Parameters**

*ds* Metafile datastream.
