Re: Question about bits (debugging>

I am working on a graphics program but my question has nothing to do
with graphics but trying to get an algorithm to work. I set graphics
from a 16x16 grid to bits of a graphic with:

       bitData[index++] = binTemp[0] * 128 + binTemp[1] * 64 +
                      binTemp[2] * 32 + binTemp[3] * 16 +
                      binTemp[4] * 8 + binTemp[5] * 4 +
                      binTemp[6] * 2 + binTemp[7];

But I want to populate that same pad from bits:

void populate(int num){
 int bits[8] = {0,0,0,0,0,0,0,0};
 int counter = 0;
 int placer = 0;
 BYTE temp;
 clear();
 std::vector<BYTE> vb = work.getBits();
 std::vector<BYTE>::const_iterator itr = vb.begin();
 for(int dwn = 0; dwn < work.getPixels(); dwn++){
   for(int acc = 0; acc < 2; acc++){
     if(acc == (num) || acc == (num+1)){
       temp = *itr;
       if(temp >= 128){
         bits[0] = 1;
         temp=-128;
       }
       if(temp >= 64){
         bits[1] =1;
         temp-=64;
       }
       if(temp >= 32){
         bits[2] =1;
         temp-=32;
       }
       if(temp >= 16){
         bits[3] =1;
         temp-=16;
       }
       if(temp >= 8){
         bits[4] =1;
         temp-=8;
       }
       if(temp >= 4){
         bits[5] =1;
         temp-=4;
       }
       if(temp >= 2){
         bits[6] =1;
         temp-=2;
       }
       if(temp >= 1){
         bits[7] =1;
       }
     table[0+(counter*8)] = bits[0];
     table[1+(counter*8)] = bits[1];
     table[2+(counter*8)] = bits[2];
     table[3+(counter*8)] = bits[3];
     table[4+(counter*8)] = bits[4];
     table[5+(counter*8)] = bits[5];
     table[6+(counter*8)] = bits[6];
     table[7+(counter*8)] = bits[7];
     for(int l = 0; l != 7; l++){bits[l]=0;}
     counter++;
     itr++;
     }
   }
 }
}

It does not work. It messes up if the number is over 128 that is the
first bit 10000000 is above 128. Anything thing look wrong. I will
send my program or post more code if that is needed.
