-

i'am trying convert svg image created svggraph library ( http://www.goat1000.com/svggraph.php).

the svg colored (red, green, yellow, gray, ...) in browser , fine. when convert it, black , white.

with code convert it: 

//new instance of imagick $im = new imagick(); //read svg file/data (its not saved on filesystem) $im->readimageblob($svgfile);  $im->setimageformat("png24"); $im->writeimage('cylinder.png'); $im->clear(); $im->destroy();

i've tried jpeg , png output format result same, colors replaced black

does have idea how fix ?

try way:

$im = new imagick(); $im->setbackgroundcolor(new imagickpixel('transparent')); $im->readimageblob($svgfile);  $im->setimageformat("png24"); $im->writeimage('cylinder.png'); $im->clear(); $im->destroy()

(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...
