i have programming issue regarding extraction of subimage (submatrix) bigger image (matrix). have 2 points (upper , lower bound of subimage want extract) , want extract subimage bigger 1 based on these points. can't find how thins c/c++. i know it's easy matlab. suppose these 2 points (x_max,y_max) , (x_min,y_min). extract subimage need code following: (matlab code)-> small_image=big_image(x_min:x_max,y_min,y_max); but in c can't use interval of indexes : matlab. here faced problem before? if doing image processing in c/c++, should use opencv . the cv::mat class can using region of interest (roi) .

i reading paper "simple, fast, , practical non-blocking , blocking concurrent queue algorithms" , realized that assume computer implements following pseudo-code atomically: cas(q->tail,tail,<next.ptr,next.count+1>) where q->tail , tail pointer , instance of struct containing pointer , counter. i know gcc provides couple of build-ins single word compare , swap in c. however, possible implement non-blocking atomic double compare , swap single compare , swap in c (using linux)? right approach implement pseudo-code of referenced paper? i don't know of cas operations work on 2 distinct memory locations. however, it's possible paper using struct pointer , counter workaround treat both fields larger type, , therefore, change both atomically. assuming have struct of 2 fields, pointer , counter: pointer size of 4 bytes, counter size of 4 bytes; aligned without padding struct size of 8 bytes. assuming have cas operation handles values of 8 byte

i doing application creates video using set of photos saved in sd-card. problem trying fix application crashes when create videos. crashes depends of resolution of source picture files. example, can render video using 400 images resolution of 320x480 can 25-frames video using images resolution of 2500x3200. i doing rendering process in background using asynctask (for providing feedback user , maintain informed of rendering process). when rendering process crashes no warnings/errors/etc captured in logcat. using ddms examining memory usage can not view memory leak (i not recieve memory warning on logcat). reasons supose may problem related ffmpeg libraries (but have no idea). i have testet different codecs defined on avcodec.java, like: av_codec_id_mpeg1video = 1, av_codec_id_mpeg2video = 2, av_codec_id_h263 = 5, av_codec_id_mjpeg = 8, etc trying lossless video codecs seems not doing effect, , errors when try codecs. i running application on sony ericsson xp

is there (preferably easy) way load .tmx file in ios 7's sprite kit? if not, there alternatives? check out tilemapkit sprite kit. unlike other solutions loads , renders (!) map types , variations supported tiled, including staggered iso , hex maps! tilemapkit engineered oop framework should be, , exposes data stored in tmx file. in other words it's not single class got crammed it. tile picking (point coord, coord point conversion) map types/variations built-in. more awesome features on way, review roadmap , check out class reference . tilemapkit tested fully compatible swift , mac apps, too. visit tilemapkit forum if have questions or requests. i'm posting frequent development reports can check what's coming next. disclaimer : if isn't obvious now, i'm 1 of tilemapkit developers. :)

there group of 10 jpanels placed in gridlayout. want drag 1 jpanel(for instance panel1) , place on jpanel (for instance panel2) , move panel2 left or right , place panel1 in panel2 position. able drag jpanel using drag option, not able drop @ required position. need in moving panels in drop location. sorry, if question not clear. hope understand. in advance. you try this, said, there's better way: public jpanel getpanelcolliding(jpanel dragpanel, jpanel[] panels) { rectangle rdrag = dragpanel.getbounds(); (jpanel panel : panels){ if (panel == dragpanel) continue; rectangle r = panel.getbounds(); if (r.insersects(rdrag)) return r; } return null; } then in drag listener can call , swap panel locations if getpanelcolliding() not null. didn't test this, should work!

i'm having bit of problem overlappingmarkerspiderfier google maps api: near start of script, store of markers in array called "parentnodes". when click on marker, need able detect "id" of marker ("id" property of each marker set whenever initialising them) can run function hides of markers except 1 clicked on. i've tried adding listener each marker after initialise them, wouldn't recognise array, though it's global, giving me error "parentnodes[i] undefined" whenever clicked on marker. for(var = 0; < parentnodes.length; i++) { oms.addlistener('click', function() { console.log(parentnodes[i].id); }); } i thinking better solution have 1 listener, there way of accessing properties of marker if listener doesn't know 1 clicked on , whether or not other markers underneath it? or listener know somehow? this faq

why creation of object needs constructor? if don't define constructor default constructor generated ..but why constructor necessary? why can't objects created without constructor? this more of discussion on terminology real argument behavior. mention, in cases there nothing done during construction, there should no need constructor, right? well, there concept of trivial-constructor constructor not @ all. sake of standard document, easier treat having (possibly trivial) constructor have provide cases , exceptions in places states 'constructor'. consider every use of 'constructor' have replaced 'constructor or nothing if type not have virtual functions or bases , no members require generation of constructor'. this same reason why virtual functions called overrider first 1 in hierarchy definition not override anything. form of generalization makes language easier interpret, although not many people claim section 8.5 on initializati

i not have enough information wpf, please correct me. seems handle different views create many usercontrols needed(each view needs 1 usercontol binds viewmodel) , , using mvvm pattern designers can create views independently. if designer tries create 2 themes different structure, has create 2 usercontrols because when using usercontrols layout specified(as mentioned here ). on other way customcontrols not specify layout, seems using customcontrols more reasonable. question: using custom controls instead of usercontrols correct, , if is, reasonable viewmodels inherit control, , views become styles viewmodels? unless need functionality provided custom controls, suggest using usercontrols or datatemplates. simpler. here's related question\answer. wpf user controls vs custom controls

ok. have old powermac g5 , decided use staging server. i went along trying normal installing rails things, when experienced error. could not find javascript runtime. see https://github.com/sstephenson/execjs (github) list of available runtimes (execjs::runtimeunavailable). execjs , not find javascript runtime as far can tell, because there no javascript runtime execjs call. people suggested installing node-js fix problem. makes sense. turns out, node, requires v8 javascript engine, required arm or i386, doesn't run on ppc. so screwed, or there javascript runtime can use rails. , how set up? thanks. here ppc port of v8 actively developed ibm folks: https://github.com/andrewlow/v8ppc

lets i've created new feature git flow feature start featurename then published git flow feature publish featurename now colleague wants collaborate on feature me, does git flow feature pull featurename this creates new branch on local repo, based on feature branch in remote repo. not set local feature branch track remote feature branch, has track branch manually. what reasoning behind step? why not have feature pull command set track well? what's workflow difference between git flow feature pull , git flow feature track . in cases use each of those? sounds using git flow feature pull , should using git flow feature track , since create local branch tracks remote. i can't think of why i'd ever use git flow feature pull . creates local branch no tracking set on it, , don't know why useful! it's badly named, since pull should involve merge, , not.

this question has answer here: how string terminates in java? 3 answers as title suggests, it's theoretical question. i'd know if java defines string null terminated. i'd know if java defines string null terminated. no. string defined fixed length sequence of char values. possible char values (from 0 65535) may used in string. there no "distinguished" value means string ends. so how track string ending? using length? yes. string object has private length field (in implementations i've examined ...). if want understand more how java strings implemented, source code various versions available online. google "java.lang.string source".

i have come love syntax in ocaml match mycompare x y |greater-> |less-> |equal-> however, needs 2 things, custom type, , mycompare function returns custom type. would there anyway without doing steps above? the pervasives module seems have 'compare' returns 0 if equal, pos int when greater , neg int when less. possible match those? conceptually (which not compile): match mycompare x y | (>0) -> | (0) -> | (<0) -> i know use if statements, pattern matching more elegant me. there easy (if not maybe standard) way of doing this? is there easy … way of doing this? no! the advantage of match on switch in language ocaml's match tells if have thought of covering cases (and allows match in-depth , compiled more efficiently, considered advantage of types). lose advantage of being warned if stupid, if started using arbitrary conditions instead of patterns. end construct same drawbacks switch . this said, actually, yes! y
