thumbnails - Image gallery assistance if you may -


i created image gallery works great, problem have don't know how set program when open it opens pictures thumbnails , if click on thumbnails image expands. 

int maximages;  int imageindex;  // declaring array of images. pimage[] images;  void setup() {    size(600,400);    images = new pimage[maximages];    maximages = 2;   imageindex = 0;     // initial image displayed first    (int = 0; < images.length; ++ ) {     images[i] = loadimage( "changeling" + + ".jpg" );    }  }  void draw() {    // displaying 1 image   image(images[imageindex],0,0);   }

here it's idea, show images i'm setting them whit width , height of 100 can use value or own algorithm best sizes. knowing space in sketch every image occupies can know when mouse inside 1 of them when mouse click event happen. proceed expand image doubling size until reaches size comparing whit screen size, again can use own value or algorithm best expansion ratio. once mouse it's clicked again when image expanded goes thumbnail again.

hope can useful.

int maximages;  int imageindex; boolean imageexpand;  // declaring array of images. pimage[] images;   void setup() {    size(600,400);    maximages = 2;   imageindex = 0; // initial image displayed first   boolean imageexpand;    images = new pimage[maximages];       imageexpand = false;    (int = 0; < images.length; ++ ) {     images[i] = loadimage( "changeling" + + ".jpg" );    }  }  void draw() {    if(!imageexpand){     showthumbnail();   }  }  void mouseclicked(){    if(!imageexpand){     for(int i=0; < images.length; i++){       if((images[i].x > mousex) && (images[i].x + images[i].width < mousex)){         if((images[i].y > mousey) && (images[i].y + images[i].height < mousey)){            expandimage(images[i]);           imageexpand = true;         }       }     }   }   else{     imageexpand = false;     showthumbnail();   }  }  void expandimage(pimage myimage){    int largewidth, largeheight;    while((myimage.width * 2 < 600) && (myimage.height * 2 < 400)){     largewidth = myimage.width * 2;     largewidth = myimage.height * 2;   }    image(myimage, 0, 0, largewidth, largeheight);  }  void showthumbnail(){    int posx = 0, posy = 0, lastimage = 0;   for(int i=0; < images.length; i++){     if(posx + 100 < 600){       image(images[i], posx, posy, 100, 100);       posx = posx + 100;     }     else{       posx = 0;       posy = posy + 100;       image(images[i], posx, posy, 100, 100);     }   }  }

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
