## 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.

## Member Function Documentation

void EMF::EMRSCALEVIEWPORTEXTEX::execute | ( | METAFILEDEVICECONTEXT * | source,
|  | HDC | dc
