Questions? Answers? Comments?
chage the first for loop to this, and you're golden. we did this one in recitation.
for (int srcx = getWidth()-1, trgx= 0; srcx >= 0; srcx–, trgx++);
Removed at KS request
Anyone want to try writing the code to flip horizontally, top and/or bottom? It's always good to cover the bases...

//*Flip horizontally, top.
public Picture fliphor() {
Pixel currPixel;
Picture target = new Picture((int) this.getWidth(),this.getHeight());
for (int srcx = 0, trgx = 0; srcx < getWidth(); srcx++, trgx++)
{
for (int srcy = 0, trgy = getHeight()-1; srcy < getHeight(); srcy++, trgy--)
{
currPixel = this.getPixel(srcx,srcy);
target.getPixel(trgx,trgy).setColor(currPixel.getColor());
}
};
return target;
}
//*Flip horizontally, bottom.
public Picture fliphor2() {
Pixel currPixel;
Picture target = Picture target = new Picture((int) this.getWidth(),this.getHeight());
for (int srcx = 0, trgx = 0; srcx < getWidth(); srcx--, trgx++)
{
for (int srcy = getHeight(), trgy = 0; srcy >= 0; srcy++, trgy++)
{
currPixel = this.getPixel(srcx,srcy);
target.getPixel(trgx,trgy).setColor(currPixel.getColor());
}
};
return target;
}
How about those? I know someone did this with their HW2 collage, so correct me, please.
