i'm using pillow image processing in python, url="http://www.image.com/some_image.jpg"; path = io.bytesio(urllib.request.urlopen(url).read()) original_image = image.open(path) any idea how can size of image file using pillow? i'd process image size before storing disk the answer going depend on format save image in, accurate solution along lines of: >>> out = io.bytesio() >>> original_image.save(out, format='png') >>> out.tell() # size in bytes if want size of uncompressed pixel data, need know how many bits in pixel. don't believe exposed in pillow, you'll have lookup value using original_image.mode , reference unpack.c . width * height * bytes_per_pixel . if image uses palette, gets more complicated , i'd recommend using first method.

i learning java swings, , creating 1 frame , want add more 1 panel different orientations, see below in code jpanet_1 , jpanel_2 each of them has specific dimensions set using setbound() method. the problem @ run time, "hello world" appears in second panel , not appear in first one. tried switch order in adding 2 panels main frame follows: jframe_2.add(jpanel_2); jframe_2.add(jpanel_1); but then, "hello world" added panel_2 only. please let me know how add 2 panels frame the statement "hello world" appears in both as see in code, specifying dimensions each panel wish add frame, add it, there other recommended way add panels frames? code: public class gui_01 { jframe jframe_1; jframe jframe_2; jpanel jpanel_1; jpanel jpanel_2; final jlabel jlabel_hello = new jlabel("hello world"); joptionpane joptions; final string[] options = {"yes", "no", "maybe"}; public gui_01() { // to

i'm developing wp8 , need store custom app settings. found func 'applicationdata' it's not supported in wp8. can me? want store permanent variables provided user. example: country = ua news = 1 etc. you can use isolated storage or applicationdata.localsettings : var localsettings = windows.storage.applicationdata.current.localsettings; // create simple setting localsettings.values["examplesetting"] = "hello windows"; // read data simple setting object value = localsettings.values["examplesetting"]; if (value == null) { // no data } else { // access data in value } // delete simple setting localsettings.values.remove("examplesetting"); check link , link

a = b(1, :) .. copies first row of b a. is there anyway create matrix view object, like frb = view(b(1, :)) to able refere view of matrix ? also, make so b(1, 3) = 123123; % set b(1, 3) 123123 illustration purposes frb(3) = 9999; % set b(1, 3) 9999 disp(b(1, 3)); % prints 9999 see numpy example that: http://docs.scipy.org/doc/numpy/reference/generated/numpy.ndarray.view.html you can use pointers in matlab point same matrix without making copy. here's simple example based on code using pointers in matlab first define class inherits handle class, matlab's pointer class. class properties store matrix. classdef handleobject < handle properties object=[]; % matrix end methods function obj=handleobject(receivedobject) %this constructor obj.object=receivedobject; end end end to declare matrix , matrix view, following m = handleobject(ones(5,5)); %the constructor passes matrix object property

i have read in file such as apple grape banana and store string, fgets reads newline , stops, reading in apple. how around this? or how can store 3 words separate strings? char* readfile(const char *filename) { file *infile; infile=fopen(filename, "r"); char **stringinfile; stringinfile = malloc(sizeof(char*)*50); char *data = fgets(stringinfile,50,infile); printf("%s", data); fclose(infile); return data; } this in c btw. fgets() reading one line each call, , sets file courser next line. if want read file, have iterate it. check if @ end, can check eof flag feof() . resulting in, me working: char* readfile(const char *filename) { file *infile; infile=fopen(filename, "r"); char **stringinfile; stringinfile = malloc(sizeof(char*)*50); while(!feof(infile)) { printf("%s", fgets(stringinfile,50,infile)); } fclose(infile); return stringinfile; } and, don't need variable data - f

is there examples out there template metaprogramming better use new constexpr? i've understood, both constexpr , template metaprogramming have similar purposes, yet template metaprogramming not obsolete. there has examples template metaprogramming preferred on constexpr. shared thoughts on highly appreciated, thanks! constexpr provides true support compile-time computing in form of true c++ functions instead of functional-like template-based constructions (metafunctions). partially answer yes constexpr beats tmp on compile time computing , @ least on syntax no fp initiated people used c++. note i'm ignoring concerns compiler performance etc. on other hand, tmp still relevant, , way, type computing in c++ . there new approaches improve horrible tmp syntax, boost.hana template variables. despite syntax, still functional metalanguage separated "normal" c++. about type computing from 2 common tasks may ask c++ compiler (besides compiling), playing typ

my table looks table (id, attribute, value, expires, static) i'd able update table new values of value, expires or static when entry id/attribute pair exists. create new entry every new id/attribute pair , every new id. i new @ using sqlite , have seen few posts similar problem sqlite - upsert *not* insert or replace not address i'm trying do. maybe approach , need different table format. please let me know thoughts/suggestions. just put logic program: bool ok = query.exec("update ..."); ... if (query.numrowsaffected() == 0) { ok = query.exec("insert ..."); ... }

i've installed , configured django app lbforum on windows 8.1 , cannot run. ultimate goal run alongside mezzanine, can't run on own. here's i've done: (as precondition following steps, have following c/c++ compiler installed support pip. http://www.microsoft.com/en-us/download/details.aspx?id=44266 . batch file vcvarsall.bat on path environment variable.) perform fresh install of python 2.78. used activestate distribution 64 bit. i uninstall , reinstall virtualenv because of bug per these instructions ( https://askubuntu.com/questions/400343/trying-to-create-a-python-virtual-environment-but-getting-oserror ) next activate new environment env\scripts\activate.bat next install lbform pip install lbforum fails because of "pil" install itself. pip install pil --allow-unverified pil --allow-all-external per installing pil pip . then install lbform pip install lbforum seems work fine reports success next use standard django commands creatin

this question has answer here: “var” or no “var” in javascript's “for-in” loop? 9 answers i've seen javascript code has used 2 different ways of defining loop. for (var i=0;i < x.length; i++) but it's been for (i=0; < x.length; i++) the same thing has happened for-in loops for (var in x) and for (i in x) is there difference between declaring i var , saying i ? there advantages of doing 1 on other? 1 these right way this? can tell, both act same, there has difference. note: i'm not asking difference between for-in , for (i=0) without var declaration somewhere in function, references i i property of global object. risks sorts of unpredictable behavior if code in body of for loop invokes code (say, inside called method) modifies global i . note declaring var i in for loop initialization for (var = ...) is
