HOperatorSet.GenRandomRegions 有内存泄漏或缓存，释放不掉

开发环境

VS2022 win7 halcon12 halcon18

随机生成100个园

不释放

private void butTemp_Click(object sender, EventArgs e)
{
butTemp.Enabled = false;
HOperatorSet.SetSystem("clip_region", "false");
{
HObject ho_regions;
HOperatorSet.GenRandomRegions(out ho_regions, "circle", 10, 20, 10, 30, -0.7854, 0.7854, 1000*1000, 5210, 5210);
int iObjNum = WHCSHalCon.Base.CountObj(ho_regions);
// regions.Dispose();
}
butTemp.Enabled = true;
}
内存大约增加900M。

释放

private void butTemp_Click(object sender, EventArgs e)
{
butTemp.Enabled = false;
HOperatorSet.SetSystem("clip_region", "false");
{
HObject ho_regions;
HOperatorSet.GenRandomRegions(out ho_regions, "circle", 10, 20, 10, 30, -0.7854, 0.7854, 1000*1000, 5210, 5210);
ho_regions.Dispose();
}
butTemp.Enabled = true;
}
似乎没效果，内存还是增加了900M。

不裁剪，宽高限定为521

private void butTemp_Click(object sender, EventArgs e)
{
butTemp.Enabled = false;
//HOperatorSet.SetSystem("clip_region", "false");
{
HObject ho_regions;
HOperatorSet.GenRandomRegions(out ho_regions, "circle", 10, 20, 10, 30, -0.7854, 0.7854, 1000*1000, 521, 521);
ho_regions.Dispose();
}
butTemp.Enabled = true;
}
