how about

collide=0
for(int a = 1; a <= pptest_w && !collide; a++){
   for(int b = 1; b <= pptest_h && !collide; b++){
      pixelcheck = getpixel(pptest_1a, a, b); 
      if(pixelcheck <= 0){
      }else if(pixelcheck != 0){
         pixelcheck = getpixel(pptest_2a, a, b);
         if(pixelcheck <= 0){
         }else if(pixelcheck != 0){
            collide = 1;
         }
      }
   }
}
