c# - Getting Rectangles stacked vertically to horizontally but keeping shape -

-

i have input done correctly rectangles stacked vertically , have different colors each time new rectangle drawn, struggling output bottom pic. please can put me on right path.

rectangles

    //list strore randomly generated rectangles     list<rectangle> rectanglecollection = new list<rectangle>();     //counts amount of time rectangle needs drawn     int count = 0;      public static random ran = new random();      void createrectangle()     {         int tallestrectangle = 0; ;           int prevrecy = 0;          graphics graphic = picturebox1.creategraphics();         solidbrush brush;          foreach (rectangle rect in rectanglecollection)         {             if (rect.height > tallestrectangle)                 tallestrectangle = rect.height;         }          foreach (rectangle rect in rectanglecollection)         {             graphic.fillrectangle(brush = new solidbrush(color.fromargb(ran.next(1, 255), ran.next(1, 255), ran.next(1, 255))),                 new rectangle(rect.x + prevrecy, (tallestrectangle - rect.height), rect.width, rect.height));              prevrecy += rect.width;         }     }      private void button1_click(object sender, eventargs e)     {         count = int.parse(textbox1.text);         (int = 0; < count; i++)         {             getrandomrectangle();         }         createrectangle();     }      void getrandomrectangle()     {         graphics graph = this.creategraphics();         int x = 0;         int y = 0;          int width = ran.next(20, 100);         int height = ran.next(30, 150);          rectangle rec1 = new rectangle(x, y, width, height);         rectanglecollection.add(rec1);     }

for each rectangle, ordered shortest tallest,

  • make horizontal rectangle of height, starting left of rectangles taller that, ending @ right of rectangles right of that.

whenever you're creating horizontal rectangle place on top of highest horizontal rectangle below (in terms of hiorizontal position) 1 you're creating.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

Image
i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.

Cloning queue in c# -

i have following code: queue<string> oldqueue = new queue<string>(); oldqueue.enqueue("one"); oldqueue.enqueue("two"); oldqueue.enqueue("three"); queue newqueue = oldqueue; string newstring = newqueue.dequeue(); the problem once dequeue item newqueue , item dequeued oldqueue . there way "clone" queue in way removing item 1 queue keep it's clone queue unchanged? queue reference type, newqueue , oldqueue holds pointer same object. same ;-) see answer how "deep cloning" using reflection: deep copy using reflection in extension method silverlight?
