i attempting create simple .pdf using libary itextsharp. making .pdf header & footer have images in them , header margin 300px & footer margin 664px. my problem: code doesn't insert header image reason , footer image blown up/scaled in size reason. can tell me whats wrong code. header image should extend whole width of a4 page & 300px in height. footer image should extend whole width of page & 664px in height. both images dont need resized whole width of page & correct heights. public class itseventshandler : pdfpageeventhelper { pdftemplate total; basefont helv; // following tutorial & said if want create headers/footers when each page created // should override onendpage() not onstartpage() correct? public override void onendpage(pdfwriter writer, document document) { // post: when each new page created, add header & footer image page. , set top margin 370px // , bottom margin 664px. /

is there standard way of restricting results of sparql query belong specific namespace. short answer - no there no standard direct way this long answer - yes can limited form of string functions , filter clause. function use depends on version of sparql engine supports. sparql 1.1 solution almost implementations these days support sparql 1.1 , can use strstarts() function so: filter(strstarts(str(?var), "http://example.org/ns#")) this preferred approach , should relatively efficient because simple string matching. sparql 1.0 solution if stuck using implementation supports sparql 1.0 can still uses regular expressions via regex() function slower: filter(regex(str(?var), "^http://example\\.org/ns#")) regular expressions , meta-characters note regular expression have escape meta-character . otherwise match character e.g. http://examplexorg/ns#foo considered valid match. as \ escape character both regular expressions , sparql

i'm trying use brownian motion create group of random moving particles. http://jsfiddle.net/j75em/16/ so far i've got particles moving randomly i'm not sure how set forward direction make more natural. i've tried use change in x , y axis calculate rotation using atan, can see uncommenting rotate doesn't seem perform well. is right approach type of movement? thanks; this pretty neat! you sort of going right way should use atan2 function. removes need 0 checks. the atan2 function gives angle anticlockwise positive x vector (1, 0) ---> the bees 90 degrees off starting angle must subtract 90 degrees direction. (depending on way round dy , dx calculation, might need add) you find direction changes rapidly, consider limiting next change set of changes cause angle change below threshold. make movement little smoother. i go generating angle between -pi/8 , pi/8 radians, , random length. using polar coordinates. add new random polar offset

i looking sound algorithm randomly place given number of rectangles of same size bigger rectangle (canvas). i see 2 ways it: create empty array contain rectangles placed on canvas. start empty canvas. in loop, pick position @ random new rectangle placed. check if array has rectangle overlaps new rectangle. if not, put new rectangle in array , repeat loop. otherwise, pick new position, , rerun check again. , on. might never terminate (theoretically) think. not it. use grid , place rectangles cells randomly. might still grid placement. not either. any better ways it? "better" meaning more efficient, or more visually "random" grid approach. better in respect. here simple heuristic. non-overlapping , random. place rectangle randomly. then, calculate intersections of extensions of the 2 parallel edges of first rectangle edges of canvas. obtain 4 convex empty regions. place other rectangles in these empty regions one-by-one independently , calculat

how calculate angle between 1 object , assuming first object origin , vector is, up? struggled problem in android , java 6 hours , there wasn't questions or answers gave correct way calculate it. if question not super clear: have object on screen , want know angle object being y axis (or 90 degrees) object on screen. if first object @ 1,1 , second object @ 2,2, angle should 315. because 0 degrees right, 90 degrees (y axis), 180 degrees left, , 270 degrees down. there might more elegant solutions, found works well: float angle = (float)math.todegrees(math.atan2((double)(y1 - y2),(double)(x1 - x2))); angle = (angle + 180.0f) % 360.0f; angle = 360.0f - angle; this gives angle starting 0 right, 90 up, 180 left, , 270 down. answered own question because took me on day find , wasn't on internet. hope helps someone. i'll leave question unanswered day or two, see if can find more elegant solution or better way of expressing answer. answer in java , has been teste

i have set of numbers: 1,22 1,46 32,1 1,9 32,22 1,14 1,45 1,33 33,22 45,22 32,46 32,9 3,1 3,9 3,22 3,32 3,46 9,22 46,22 46,45 46,33 15,1 15,46 15,6 15,22 15,3 15,9 15,45 15,33 15,32 15,14 i need combinations them rule each new pair can appended if latter number same first in pair. for example if have pair {15,1}, next on can {1,46} , next {46,45}, , final pair must end first number of whole set. in case example {45,1}. so end result of sets 4 set limit {15,1,1,46,46,45,45,1} i can basic power sets , generate possible combinations set of numbers seems advanced me. i can c, javascript or php or solutions highly appreciated. , clarification, not homework, learn , understand. this looks if graph data structure, , graph algorithms, appropriate. graph comprise nodes (each of number) , edges (each of represents 1 of pairs). write appropriate routine walking round graph. it's not entirely clear question rules walk are, guess know. edit of course, should po

recently working on company i'm realize start having troubles methods return html based on partial views. problem changes not loaded internet explorer because browsers has configures remains in cache information , cannot see changes base on partial view. changes not affected in other browsers firefox , chrome. the problem solved modifying options of internet explorer , checking options on browsers client so. have couple of questions is there configuration or meta tag can used in javascript, html or jquery handle kind of error without modified browser configuration. where can find documentation troubles if issue ajax related...try setting cache:false in ajax options. if using convenience methods get() or load() can globally using $.ajaxsetup() http://api.jquery.com/jquery.ajax/ http://api.jquery.com/jquery.ajaxsetup/

my index.js.erb refreshing page partially: $("#view").html("<%= escape_javascript render 'view' %>"); i able refresh in controller line: format.js { render :js => "window.location.replace('#{url_for(:controller => :view, :action => :index, :some_parameter => value)}');" } is possible refresh page in js.erb? edit: call index.js.erb command in controller: format.js { redirect_to(:action => :index, :format => :js, :some_parameter => value)}, it refreshes page content some_parameter, refreshes partially. window.location works better, read in 1 of stack overflow posts better use erb controller javascript. really? for second way, you're refreshing whole page( made http request ) , if want this, why not use redirect_to ?
