Halcon之HTuple数据和VC数据的相互赋值

// HTuple→VC 数据类型转换
HTuple hTuple = 1234;
int i = hTuple[0].I();                  // i=1234
long l = hTuple[0].L();                 // l=1234
long lNumber = hTuple.Num();            // lNumber=1，数据个数
double d = hTuple[0].D();               // d=1234.0000
   
hTuple = "1234";
CString strBuffer = hTuple[0].S();      // strBuffer="1234"
   
   
// VC→HTuple 数据类型转换
int ii = 1234;
double dd = 1234.1234;
CString strTemp = "Halcon";
   
HTuple hTuple2;
hTuple2[0] = ii;                        // hTuple2[0].I()=1234
hTuple2[1] = dd;                        // hTuple2[1].D()=1234.1234
hTuple2[2] = strTemp.GetBuffer();       // hTuple2[2].S()="Halcon"
   
i = hTuple2[0].I();                     // i=1234
d = hTuple2[1].D();                     // d=1234.1234
strBuffer = hTuple2[2].S();             // strBuffer="Halcon"
lNumber = hTuple2.Num();                // lNumber=3，数据个数

 HTuple类型数据提取 

 

从HTuple类型读取数据

//HTuple有一个元素

HTuple aa = 120;
double dd = aa[0].D(); // dd=120.000
int ii = aa[0].I(); //ii=120
long ll = aa[0].L(); //ll=120
Hlong hh = aa[0].L();//hh=120
long num = aa.Num(); //num =1;
aa = "120"; //HTuple为字符串时，如果赋值不是字符串，不能调用S()函数
const char *cc;
cc = aa[0].S(); //cc[0]='1',cc[1]='2',cc[2]='0'

//当aa为多元素的数组时

aa[1] = 230;
num = aa.Num(); //num =2;
ii = aa[1].I(); //ii=230   //其他获取数据的方法与上面类似
