xml - extracting metadata from jpeg2000 images in python -


i'd update metadata in series of jpeg2000 images. , i'd using python. i've looked @ glymur , have been able extract xml etree:

import glymur lxml import etree  jp2 = glymur.jp2k(file) metaroot = jp2.box[3].xml  # 4th element in box contains metadata want fitshdr = metaroot[0]  # metadata originated fits header

then can tags , tag values:

for kw in fitshdr:     tag = kw.tag     val = fitshdr.findtext(tag)     # tags , values

my question is: there easier way? seems unnecessarily complicated.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
