[mapserver-users] confused about using zoomRectangle

[Tamas Szekeres]

I'm using this one for C# which is working fairly well.

public void ZoomRectangle(double minx, double miny, double maxx, double
maxy)
        {
            if (map != null && (maxx - minx) > 2 && (maxy-miny) > 2)
            {
                using (rectObj imgrect = new rectObj(minx, miny, maxx, maxy,
0))
                {
                    // mapscript requires this hack
                    imgrect.miny = maxy;
                    imgrect.maxy = miny;

                    map.zoomRectangle(imgrect, map.width, map.height,
map.extent, null);
                    this.RefreshView();
                    return;
                }
            }
        }


I guess the same would work for java as well.

Best regards,

Tamas
