EmfScaleViewportExtex

EmfScaleViewportExtex class

The EMR_SCALEVIEWPORTEXTEX record respecifies the viewport for a device context by using the ratios formed by the specified multiplicands and divisors.

public sealed class EmfScaleViewportExtex : EmfStateRecordType

Constructors

Name Description
EmfScaleViewportExtex() Initializes a new instance of the EmfScaleViewportExtex class.
EmfScaleViewportExtex(EmfRecord) Initializes a new instance of the EmfScaleViewportExtex class.

Properties

Name Description
Size { get; set; } Gets or sets the size of the record
Type { get; set; } Gets or sets the type.
XDenom { get; set; } Gets or sets a 32-bit signed integer that specifies the horizontal divisor. Cannot be zero.
XNum { get; set; } Gets or sets a 32-bit signed integer that specifies the horizontal multiplicand. Cannot be zero.
YDenom { get; set; } Gets or sets a 32-bit signed integer that specifies the vertical divisor. Cannot be zero.
YNum { get; set; } Gets or sets a 32-bit signed integer that specifies the vertical multiplicand. Cannot be zero.

Remarks

The extent cannot be changed if the device context is using a fixed scale mapping mode. Only MM_ISOTROPIC and MM_ANISOTROPIC are not fixed scale. The viewport extents are modified as follows. xNewWE = (xOldWE * xNum) / xDenom yNewWE = (yOldWE * yNum) / yDenom
