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) .

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!

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

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...
