Purpose

This sample program demonstrates how to:

□

Load an image and apply a gauge from EasyGauge, chosen between a Point Gauge, a Line Gauge, a Rectangle Gauge, a Circle Gauge, a Wedge Gauge and a Polygon Gauge.

□

Implement graphical edition of the gauge geometry.

□

Set and display the main parameters of the gauges: the transition polarity, the choice of measure and various display options.

Code highlights

Set the transition type to ETransitionType_Bw and perform the measurement.

m_PointGauge.SetTransitionType(ETransitionType_Bw);
m_PointGauge.Measure(&m_Image);

Draw the current gauge.

PointGauge.SetZoom(m_fZoomFactor);
PointGauge.SetPan(m_OrgX, m_OrgY);
PointGauge.Draw(drawAdapter.GetHDC());

// optional draws
if (m_bViewResults)
  PointGauge.Draw(drawAdapter.GetHDC(), EDrawingMode_Actual);

if (m_bViewSource)
  PointGauge.Draw(drawAdapter.GetHDC(), EDrawingMode_Position);

if (m_bViewFiltered)
  PointGauge.Draw(drawAdapter.GetHDC(), EDrawingMode_Match);

if (m_bViewPaths)
  PointGauge.Draw(drawAdapter.GetHDC(), EDrawingMode_SampledPaths);

if (m_bViewPoints)
  PointGauge.Draw(drawAdapter.GetHDC(), EDrawingMode_SampledPoints);
