Correct flip/mirror of pixels of an image?

That shows what a flip should be and what a mirror should be.
Code for both types of mirrors:
void mirrorLeftRight()
{
for (int x = 0; x < width/2; x++) {
for (int y = 0; y < height; y++) {
int temp = pixelData[x][y];
pixelData[x][y]=pixelData[width-x][y]
pixelData[width-x][y]=temp;
}
}
}
void mirrorUpDown()
{
for (int x = 0; x < width; x++) {
for (int y = 0; y < height/2; y++) {
int temp = pixelData[x][y];
pixelData[x][y]=pixelData[x][height-y]
pixelData[x][height-y]=temp;
}
}
}
Does this seem right for mirrors?
And for flip, just a matter of using width and height w/o dividing by 2?
