javascript - Canvas stroke text for every object in array but draw just one image -


i trying draw small image on canvas , text every person have in array. doing 

function drawpersonsoncanvas(canvas, persons) {     var workicon = '../images/work.png';     var partyicon = '../images/party.png';      var context = canvas.getcontext('2d');     var width = canvas.width;     var height = canvas.height; // randomizepositions put every object of array on random position inside canvas     persons = randomizepositions(persons, width, height);     (var in persons) {         var person= persons[i];          person['image'] = new image();         person['image'].src = (person['type'] === 'work') ? workicon: partyicon;         person['image'].onload = function() {             context.drawimage(person['image'], person['x'], person['y']);         };         context.stroketext('person ' + person['status'], person['x'], person['y']);     } }

and texts on map on positions , 1 image , x , y different ( have 5 persons in array, tried , without onload doesn't work). know change 1 picture every person?

by time each onload executed, person variable has been reassigned next element in persons.

so need create new person variable inside onload.

to this, add index person[‘image’] points correct person.

    …     person['image'].index=i;     person['image'].src = (person['type'] === 'work') ? workicon: partyicon;     …

then inside onload can recreate correct person:

        var person=persons[this.index];

so reworked code looks this...and fiddle: http://jsfiddle.net/m1erickson/xms9b/

function drawpersonsoncanvas(canvas, persons) {      var workicon = '../images/work.png';     var partyicon = //'../images/party.png';      var context = canvas.getcontext('2d');     var width = canvas.width;     var height = canvas.height; // randomizepositions put every object of array on random position inside canvas     persons = randomizepositions(persons, width, height);     (var in persons) {         var person= persons[i];         person['image'] = new image();         person['image'].onload = function() {             var person=persons[this.index];             context.drawimage(person['image'], person['x'], person['y']);             context.stroketext('person ' + person['status'], person['x'], person['y']);         };         person['image'].index=i;         person['image'].src = (person['type'] === 'work') ? workicon: partyicon;     } }

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
