Convert a TCL code to C++...

Question

3.00/5 (1 vote)

See more:

for {set i 128} {$i<256} {incr i 1} {
    eval lut SetTableValue $i [expr ($i-128.0)/128.0] [expr ($i-128.0)/128.0] [expr ($i-128.0)/128.0] 1

That's what I got in C++

for (int i; 128<256;i++)>
    eval->lut(SetTableValue(i), expr->(i-128.0)/128.0()expr->(i-128.0)/128.0()expr->(i-128.0)/128.0()1);

I don't know how to change eval->lut and expr functions. Do you know?

I tried to convert a TCL code to C++, but converter that I used didn't translate a very importnat lines of code. Can anyone make it work?

This should be:
for(int i=129 ; i<256 ; ++i)

What does eval, lut and expr means in TCL?

for (int i = 128; i < 256; ++i) {

   setTableValue(i, ((double)i - 128.0) / 128), ((double)i - 128.0) / 128), ((double)i - 128.0) / 128), 1);

}

where setTablueValue would look something like:

void setTableValue(int index, double r, double g, double b, double a) {

   data[index].r = r;
   data[index].g = g;
   data[index].b = b;
   data[index].a = a;

}

May I know which converter you are using to to convert a TCL code to C++?
