halcon学习之tuple转化操作

对tuple数组执行相关的转化操作

//通过截断一个浮点型的数据，转化为整形数据，tuple内容不允许是string类型

    HTuple tuple1 = 12.124431432;    HTuple result = tuple1.TupleInt();    cout << (Hlong)result<<endl;

//检测一个tuple是否代表是数字,输入可以是字符串、浮点数、整数。字符串内容如果都代表数字，返回1，整数、浮点数返回1，其他返回0；

    HTuple tuple2 = "0";    result = tuple2.TupleIsNumber();    cout << (Hlong)result << endl;

//转化一个(主要是指string类型)tuple到数字

    HTuple tuple3;    tuple3[0] = "102.51";    tuple3[1] = "10";    result = tuple3.TupleNumber();    cout << (double)result[0] << endl;    cout << (Hlong)result[1] << endl;

//转化一个数字类型为浮点型，不允许为string类型

    HTuple tuple4 = 586;    result = tuple4.TupleReal();    cout << (double)result << endl;

//转化一个数字类型为整形，比如2.9=3，2.1=2

    HTuple tuple5 = 2.1;    result = tuple5.TupleRound();    cout << (Hlong)result << endl;

//按照一定格式转化一个tuple为string类型

    HTuple tuple6 = 23;    result = tuple6.TupleString("10.3f");    cout << (HString)result << endl;

//返回长度为1的单个字符，（比如“0”，“a”…）对应的ASCII码所对应的值。

    HTuple tuple7 = "0";    result = tuple7.TupleOrd();    cout << (Hlong)result << endl;

//返回一个字符串中每个字符，（比如“0”，“a”…）对应的ASCII码所对应的值。

    HTuple tuple8 = "ab1";    result = tuple8.TupleOrds();    cout << (Hlong)result[0] << endl;    cout << (Hlong)result[1] << endl;    cout << (Hlong)result[2] << endl;

//TupleOrd函数的逆操作。

    HTuple tuple9 = 97;    result = tuple9.TupleChr();    cout << (HString)result << endl;

//TupleOrd函数的逆操作

    HTuple tuple10;    tuple10[0] = 48;    tuple10[1] = 98;    tuple10[2] = 99;    result = tuple10.TupleChrt();    cout << (HString)result << endl;
