android - How to swap regions in bitmap -

-

ex.:

i have bitmap size 500x500. , on bitmap have coordinates 2 regions. 1 region @ x=10, y=10, size 10x10 second region @ x=400, y=400, size 10x10

what best way swap 2 regions in bitmap.

you can trough canvas.

something like:

bitmap swapped = bitmap.createbitmap(origin.getwidth(), origin.getheight(), origin.getconfig()); canvas drawer = new canvas(swapped); drawer.drawbitmap(origin, new rect(0,0,100,100), new rect(100,100,100,100), paint); drawer.drawbitmap(origin, new rect(100,100,100,100), new rect(0,0,100,100), paint);

at point 'swapped' bitmap have origin pieces drawed in different regions.

for more see canvas documentation:

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
