Member Function Documentation

virtual signed int IZoomAdaptor::GetSensitivity ( double *  pVal )

pure virtual

Gets the Sensitivity field and puts it in the variable at address pVal. The default value is 1.0.

Parameters

pVal	The address of the variable to get the field's value.

virtual signed int IZoomAdaptor::GetZoomToLoc ( POINT *  pVal )

pure virtual

Gets the ZoomToLoc field and puts it in the variable at address pVal. The default value is the center of the image. Changing this value will change where in the image zooming will zoom towards or away from. Typically, it makes sense to use the cursor position for this value.

Parameters

pVal	The address of the variable to get the field's value.

virtual signed int IZoomAdaptor::SetSensitivity ( const double  val )

pure virtual

Sets the Sensitivity field to val. The default value is 1.0.

Parameters

val	The new Sensitivity value.

virtual signed int IZoomAdaptor::SetZoomToLoc ( const POINT  val )

pure virtual

Sets the ZoomToLoc field to val. The default value is the center of the image. Changing this value will change where in the image zooming will zoom towards or away from. Typically, it makes sense to use the cursor position for this value.

Parameters

val	The new ZoomToLoc value.
