I have a pixel perfect method that works fine except when one or more of the images are flipped(or rotated, but I wont fix that).

for (int y = top; y < bottom; y++)
{
for (int x = left; x < right; x++)
{
int colorA;
int colorB;
if(flipped1)
colorA =
else
colorA = image1.getColor((int) (x - obj1.currX), (int) (y - obj1.currY));
if(flipped2)
colorB =
else
colorB = image2.getColor((int) (x - obj2.currX), (int) (y - obj2.currY));
if (colorA != 0 && colorB != 0)
return true;
}
}
return false;

How do I calculate the current pixel to check if the image is flipped horizontally?
