how to add thousands of image into a pdf with reportlab -

-

i have 1 thousand png images,and use reportlab add these images pdf, code is:

def pic_exits(pic_path):

if os.path.exists(pic_path):     #print ('pic_exits')     #print (pic_path)     target = pil.image.open(pic_path)                 #fp = open(pic_path,'rb')     #target = pil.image.open(fp)     #fp.close()             targetx,targety = target.size     del target     #print (targetx,targety)     tx,ty = get_xy(targetx,targety)     targetimg = image(pic_path, tx, ty) else:     targetimg = paragraph('<para align = center>not exist</para>',bodystyle)       return targetimg

def draw_sourcepic(self_dir,pic_list):

pic = [pic_list[i:i+3] in range(0,len(pic_list),3)] data = [] = 0 val in pic:     eachline = []      pic_path in val:         i+=1         pic_image = pic_exits(pic_path)         eachline.append(pic_image)     while len(eachline) < 3:         eachline.append(none)     data.append(eachline)        pic_table = drawtable(data,(150,150,150),none) story.append(pic_table)

but has below error: ioerror: cannot open resource "c:\workspace\decode\2012\result\pic\510.png maybe means hava opened many images,

the offical documents said that: image (digital picture). formats supported pil/java 1.4 (the python/java imaging library supported. @ present time images flowables centered horozontally in frame. allow 2 kinds of lazyness allow many images in document lead file handle starvation. lazy=1 don't open image until required. lazy=2 open image when required shut it.

but when changed this: targetimg = image(pic_path, tx, ty, lazy = 2) has following error: attributeerror: ._file

how can add thousands of images pdf? question long,

i know year late, encountered similar problem. think problem reportlab--when lazy=2, image called upon again after needed file attribute been destroyed. i've reported issue , workaround here. hope helps.

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...
