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
