开发环境：Win7 VS2002 halcon12，直接运行Debug的exe

不释放

private void butTemp_Click(object sender, EventArgs e)
         {
             HOperatorSet.SetSystem("clip_region", "false");
             HObject region;
             HOperatorSet.GenEmptyRegion(out region);
             for (int i = 0; i < 1000; i++)
                 for (int j = 0; j < 10000; j++)
                 {
                     HObject tmpRegion;
                     HOperatorSet.GenRectangle1(out tmpRegion, i, j, i, j);
                     HOperatorSet.Union2(tmpRegion, region, out region);
                 }
             HTuple tArea, tmp;
             HOperatorSet.AreaCenter(region, out tArea, out tmp, out tmp);
             Debug.Assert(tArea > 0);            TestForm form = new TestForm();
             form.ShowDialog();
         }

不到一分钟运行结束，最多占用1G内存，运行结束占用800M内存。

释放tmpRegio

private void butTemp_Click(object sender, EventArgs e)
         {
             HOperatorSet.SetSystem("clip_region", "false");
             HObject region;
             HOperatorSet.GenEmptyRegion(out region);
             for (int i = 0; i < 1000; i++)
                 for (int j = 0; j < 10000; j++)
                 {
                     HObject tmpRegion;
                     HOperatorSet.GenRectangle1(out tmpRegion, i, j, i, j);
                     HOperatorSet.Union2(tmpRegion, region, out region);
                     tmpRegion.Dispose();
                 }
             HTuple tArea, tmp;
             HOperatorSet.AreaCenter(region, out tArea, out tmp, out tmp);
             Debug.Assert(tArea > 0);            TestForm form = new TestForm();
             form.ShowDialog();
         }

不到一分钟运行结束，最多占用0.5G内存，运行结束占用0.5G 内存。

释放region

private void butTemp_Click(object sender, EventArgs e)
         {
             HOperatorSet.SetSystem("clip_region", "false");
             HObject region;
             HOperatorSet.GenEmptyRegion(out region);
             for (int i = 0; i < 1000; i++)
                 for (int j = 0; j < 10000; j++)
                 {
                     HObject tmpRegion;
                     HOperatorSet.GenRectangle1(out tmpRegion, i, j, i, j);
                     HOperatorSet.Union2(tmpRegion, region, out region);
                     tmpRegion.Dispose();
                 }
             HTuple tArea, tmp;
             HOperatorSet.AreaCenter(region, out tArea, out tmp, out tmp);
             Debug.Assert(tArea > 0);
             region.Dispose();            TestForm form = new TestForm();
             form.ShowDialog();
         }

几乎没变化，还是0.5G左右

释放bak

private void butTemp_Click(object sender, EventArgs e)
         {
             HOperatorSet.SetSystem("clip_region", "false");
             HObject region;
             HOperatorSet.GenEmptyRegion(out region);
             for (int i = 0; i < 1000; i++)
                 for (int j = 0; j < 10000; j++)
                 {
                     HObject tmpRegion;
                     HOperatorSet.GenRectangle1(out tmpRegion, i, j, i, j);
                     HObject bak = region;
                     HOperatorSet.Union2(tmpRegion, region, out region);
                     bak.Dispose();
                     tmpRegion.Dispose();
                 }
             HTuple tArea, tmp;
             HOperatorSet.AreaCenter(region, out tArea, out tmp, out tmp);
             Debug.Assert(tArea > 0);
             region.Dispose();            TestForm form = new TestForm();
             form.ShowDialog();
         }

不到一分钟运行结束，内存几乎没增加，不到20M以内。
