C # make Eagle Eye whole process (with annotation)

AxMapControl1 is the main control

To see the event response

1. Eagle Eye Map Resource Loading

private void Axmapcontrol1_onmapreplaced (object sender, Imapcontrolevents2_onmapreplacedevent e)

{

When the main map shows the control's map to be replaced, the map in the Eagle's eye follows the replacement

Axmapcontrol2.loadmxfile (Axmapcontrol1.documentfilename);

Axmapcontrol2.extent = axmapcontrol2.fullextent;

}

2. Draw the eagle eye rectangular frame

private void SetMap2 (Imapcontrolevents2_onextentupdatedevent e)

{

Get a new range

Ienvelope penv = (ienvelope) e.newenvelope;

Igraphicscontainer Pgra = Axmapcontrol2.map as Igraphicscontainer;

Iactiveview pAv = Pgra as Iactiveview;

Clears any graphic element in the AxMapControl2 before drawing

Pgra.deleteallelements ();

Irectangleelement Prectangleele = new Rectangleelementclass ();

IElement PEle = Prectangleele as ielement;

Pele.geometry = penv;

Set the Red Line box in the Eagle's eye chart

Irgbcolor Pcolor = new Rgbcolorclass ();

pcolor.red = 255;

Pcolor.green = 0;

Pcolor.blue = 0;

Pcolor.transparency = 255;

Produces a line symbol object

Ilinesymbol poutline = new Simplelinesymbolclass ();

Poutline.width = 2;

Poutline.color = Pcolor;

Set color Properties

Pcolor = new Rgbcolorclass ();

pcolor.red = 255;

Pcolor.green = 0;

Pcolor.blue = 0;

pcolor.transparency = 0;

Set the properties of a fill symbol

Ifillsymbol Pfillsymbol = new Simplefillsymbolclass ();

Pfillsymbol.color = Pcolor;

Pfillsymbol.outline = Poutline;

Ifillshapeelement Pfillshapeele = PEle as ifillshapeelement;

Pfillshapeele.symbol = Pfillsymbol;

Pgra.addelement ((ielement) pfillshapeele, 0);

Pav.partialrefresh (esriviewdrawphase.esriviewgraphics, NULL, NULL);

}

private void Axmapcontrol1_onextentupdated (object sender, Imapcontrolevents2_onextentupdatedevent e)

{

SETMAP2 (e);

}

3. Interactive

private void Axmapcontrol2_onmousedown (object sender, Imapcontrolevents2_onmousedownevent e)

{

by YL improved landgis@126.co

Irubberband Pband = new Rubberenvelopeclass ();

Igeometry pgeometry = pband.tracknew (AxMapControl2.ActiveView.ScreenDisplay, NULL);

if (pgeometry.isempty)

{

IPoint pPt = new Pointclass ();

Ppt.putcoords (E.MAPX, e.mapy);

Change the view scope of the main control

Axmapcontrol1.centerat (pPt);

}

Else

{

Axmapcontrol1.extent = Pgeometry.envelope;

AxMapControl1.ActiveView.Refresh ();

}

}
