Location of the four corners of ArcGIS Engine extent

Location of the four corners of ArcGIS Engine extent
Upper left corner: xmin, Ymax
On the left side: xmin. The smaller the value to the left, that is, the smaller the longitude to the left.
Lower left corner: xmin, ymin
Below: ymin, the lower, that is, the lower the latitude to decrease
Top-right corner: xmax, Ymax
Top: Ymax. The larger the value is, the higher the latitude is.
Bottom right corner: xmax, ymin
Right side: xmax. The greater the value to the right, that is, increasing the longitude to the right.

// Center left

Ipoint ppointcenterleft = new pointclass ();
Ppointcenterleft. putcoords (penvelope. xmin, (penvelope. Ymax + penvelope. ymin)/2 );

// Middle right
Ipoint ppointcenterright = new pointclass ();
Ppointcenterright. putcoords (penvelope. xmax, (penvelope. Ymax + penvelope. ymin)/2 );

// Upper-right corner
Ipoint ppointcentertop = new pointclass ();
Ppointcentertop. putcoords (penvelope. xmax + penvelope. xmin)/2, penvelope. Ymax );

// Lower
Ipoint ppointcenterbuttom = new pointclass ();
Ppointcenterbuttom. putcoords (penvelope. xmax + penvelope. xmin)/2, penvelope. ymin );
