i'm trying implement method have obtain values of pixels forms line @ angle through pixel (i, j) consider following code snippet sum = image.getpixel(((i - 7), (j + 2))) + image.getpixel(((i - 6), (j + 2))) + image.getpixel( ((i - 5), (j + 1))) + image.getpixel( ((i - 4), (j + 1))) + image.getpixel(((i - 3), (j + 1))) + image.getpixel(((i - 2), (j + 1))) + image.getpixel( ((i - 1), j)) + image.getpixel((i, j)) + image.getpixel(((i + 1), j)) + image.getpixel( ((i + 2), (j - 1))) + image.getpixel(((i + 3), (j - 1))) + image.getpixel(((i + 4), (j - 1))) + image.getpixel( ((i + 5), (j - 1))) + image.getpixel(((i + 6), (j - 2))) + image.getpixel(((i + 7), (j - 2))) avg_sum = sum / 15 now in above code know pixels relative i, j forms line @ angle 15 degrees. hence able values of pixels. now there easy way because code find sum of grey level of 15 pixels forms line @ 15 degree through i, j. want code flexible can find sum of line of length 15 pixels or 13 p

just wanted know if possible eager load define accessor in laravel repository. using l5-repository package , laravel 5.4. in userinfo.php model, have function public function getfullnameattribute() { return ucfirst($this->first_name . " ". $this->last_name); } then trying eager load accessor in controller this. $user_infos = $this->repository->with('full_name')->all(); // or $user_infos = $this->repository->with('getfullnameattribute')->all(); return response()->json([ 'data' => $user_infos ]); i know not gonna work. looking similar way add accessor full_name in collection. don't need concatenate in front end. expected result { id : 1, first_name : "sample fname", last_name : "sample lname", ..... ..... full_name : "sample fname sample lname", } use $appends in model userinfo.php protected $appends = ['full_name']; this appen

i developing self graphing program draws binary tree using fabric.js. far have added draw node functions , working on drawing links between nodes, coordinates isn't getting calculated properly. can me point out error is? function(node1,node2,angle) draws node2 @ 200pixels away node1 @ angle passed. found start points of line following same method founded circle center adding circle's radius 20 in case instead of 200 pixels. end points calculated subtracting 20 200 , hence using value 180. code wrote: code: function addnode(node1,node2,angle) { var intialx=parseint(node1.get('left')); var initialy=parseint(node1.get('top')); if(angle<180) { var pointx =math.abs(math.cos(angle*math.pi/180)*200+intialx); var pointy=math.abs(math.sin(angle*math.pi/180)*200-initialy); var initiallinex=math.abs(math.cos(angle*math.pi/180)*20+intialx); var initialliney=math.abs(math.sin(angle*math.pi/180)*20-initialy);

suppose have symfony url: http:/www.site.com/page/parameter how can access "parameter" in twig? mean, conversion of $this->getpageparams() in symfony repository. i don't want explode url or similar, it's weird. thanks! in order access last element of pathinfo, following: {{ app.request.pathinfo|split('/')|last }} see this working example

i have teleric kendo ui automatic generated chart controller. , need send parameter. want load chart partial view , tryed send parameter this: @html.partial("~/views/graphs/tablestatementschart.cshtml", new { @model.servicesmodel.id } ); this doesn't work me, okay, tryed code: @{html.renderpartial( "~/views/graphs/tablestatementschart.cshtml", new { id = model.servicesmodel.id }); } and after had no data in chart diagram. how send model id in controller? this code of controller: namespace narkomapp.controllers.graphs { public class tablestatementschartcontroller : controller { private narkomdb db = new narkomdb(); int idservice = 0; public actionresult tablestatementschart(int id) { idservice = id; return view("~/views/graphs/tablestatementschart.cshtml"); } [httppost] public actionresult tablestatements_read(int id) { idservi

i wondering if me out following question: i have correlation matrix , third variable (continuous) every possible pair in correlation matrix. here toy example: set.seed(1234) x <- rnorm(1000,2,1) y <- 0.1*x+rnorm(1000,1,1) z <- y+rnorm(1000) third.dimension <- c("(x,y)" = 0.3, "(x,z)" = 0.5, "(y,z)"= 1) my.df <- data.frame(x,y,z) first, want create heatmap of correlation matrix with heatmap(cor(my.df)) next, have coloured dot within each "cell" of heatmap, depending on value of third dimension respective pair. example - if value between 0 , 0.49, have black dot, if between 0.5 , 1, grey dot etc. hence, have correlation between z , y, say, have grey dot painted in corresponding "cell" of correlation matrix. thanks in advance help! this should work you: set.seed(1234) x <- rnorm(1000,2,1) y <- 0.1*x+rnorm(1000,1,1) z <- y+rnorm(1000) third.dimension <- c("(x,y)" = 0.3, &qu

i'm new golang , not sure why prints same number rand.intn(n int) int every run: package main import ( "fmt" "math/rand" ) func main() { fmt.println(rand.intn(10)) } the docs says : intn returns, int, non-negative pseudo-random number in [0,n) default source. panics if n <= 0. and how seed random number generation? by calling rand.seed() function, passing (random) seed (typically current unix timestamp). quoting math/rand package doc: top-level functions, such float64 , int, use default shared source produces deterministic sequence of values each time program run. use seed function initialize default source if different behavior required each run. example: rand.seed(time.now().unixnano()) if rand.seed() not called, generator behaves if seeded 1: seed uses provided seed value initialize default source deterministic state. if seed not called, generator behaves if seeded seed(1).

i trying make datagridview checkboxes matrix work in particular way. mandatory requirements are. only 1 checkbox in datagridview row can selected. one checkbox per row must selected. program reading file during start , creating rows 3 out of 5 columns tick boxes column. make work in such way 1 tick box can selected per row , make impossible deselect tick box nothing in row selected. currently make sure 1 tickbox per row selected using code: private void datagridview1_cellcontentclick(object sender, datagridviewcelleventargs e) { (int = 0; <= 2; i++) { datagridview1.rows[e.rowindex].cells[i].value = false; } } nevertheless see row 2-3 have nothing selected. how can prevent unchecking checked box leave ability check other box in row? not sure want, may try this: private void datagridview1_cellcontentclick(object sender, datagridviewcelleventargs e) { if (datagridview1.rows[e.rowind
