Julia 1.1 Create a grid (array of points in a grid)


By : Fred Silva
Date : October 01 2020, 01:00 AM
wish helps you Take a look at Iterators.product. It doesn't create the Arrays, but creates an object you can iterate over to get each new element of the grid as a Tuple (which is actually usually what you want).
code :
julia> p = Iterators.product(-1.:0.5:0., -1.:0.5:0., -1.:0.5:0.);
julia> println.(p);
(-1.0, -1.0, -1.0)
(-0.5, -1.0, -1.0)
(0.0, -1.0, -1.0)
(-1.0, -0.5, -1.0)
(-0.5, -0.5, -1.0)
(0.0, -0.5, -1.0)
(-1.0, 0.0, -1.0)

find all inner grid points of a polygon made up from neighbouring grid points

will help you To find all inner grid points of grid polygon, one can exploit these observations:
for each inner grid point (x,y) also (x,y+0.5) and (x,y-0.5) are inner points. the lines defined by y=n+0.5 have simple intersections with the grid polygon
code :
list<Point> polygon; // given polygon as list of neighbouring grid points

// get centers of non-horizontal edges organized by line
map<int, set<float> > edgeCentersX; // for each scan line the x-coords of edges in ascending order

p_i = polygon[0]
yMin, yMax =  999999, -999999
for (i=1; i<polygon.size(); ++i)
    p_i1 = polygon[i] // next point after p_i
    if (p_i.x == p_i1.x)
        continue // horizontal edges can be ignored
    yMin_i = min(p_i.y, p_i1.y)
    if (yMin_i % 2 == 1)
        continue // we only need to look at each second mid-row
    if (yMin_i < yMin)
        yMin = yMin_i
    if (yMin_i > yMax)
        yMax = yMin_i
    cx = 0.5*(p_i.x+p_i1.x)
    edgeCentersX[yMin_i].insert(cx) // store edge center (yMin_i+0.5, cx)
    p_i = p_i1

list<Point> innerPoints
for (y=yMin; y<= yMax; y+=2)
    inside = false
    cx_i = edgeCentersX[y][0]
    for (i=1; i<edgeCentersX[y].size(); ++i)
        cx_i1 = edgeCentersX[y][i]
        inside = !inside
        if (!inside)
            continue
        for (x=floor(cx_i)+1; x<cx_i1; ++x)
            pLower = Point(y,x)
            if (!polygon.contains(pLower))
                innerPoints.append(pLower)
            pUpper = Point(y+1,x)
            if (!polygon.contains(pUpper))
                innerPoints.append(pUpper)

Extjs create a grid feature or grid plugin that sets a tooltip for each column in the grid


By : Attar Islem

it helps some times In your plugins init method, you will be able to loop through the columns of the grid (the constructor and initComponent methods of the grid will have already been called at this point).
That means that you can inspect each column to see if the user has setup a custom renderer. If there is none, you can put your one, and if there is one, you can chain the existing renderer with yours.
code :
Ext.define('My.Plugin', {

    init: function(grid) {

        // You may not need the scope, but if you do, this binding will
        // allow to preserve the scope configured in the column...
        var pluginRenderer = Ext.Function.bind(this.renderer, this);

        Ext.each(grid.query('gridcolumn'), function(col) {
            var renderer = col.renderer;
            col.renderer = renderer
                ? Ext.Function.createSequence(renderer, pluginRenderer)
                : pluginRenderer;
        });
    }

    ,renderer: function(value, md) {

        // ...

        // You must return, in case your renderer is the only one (if
        // there is another one, this return will be ignored by createSequence)
        return value;
    }
});

evaluate matrix expression at points in a grid using Julia

it should still fix some issue Not sure if it's the canonical Julian approach, but you could use broadcast:
code :
julia> broadcast((x,y)->f(x*y), -N:N, (-N:N)')
5x5 Array{Int32,2}:
  4   2  0  -2  -4
  2   1  0  -1  -2
  0   0  0   0   0
 -2  -1  0   1   2
 -4  -2  0   2   4
julia> f((-N:N) .* (-N:N)')
5x5 Array{Int32,2}:
  4   2  0  -2  -4
  2   1  0  -1  -2
  0   0  0   0   0
 -2  -1  0   1   2
 -4  -2  0   2   4

How can i create a Bootstrap like 12 column ( only grid ) grid system using new CSS GRID Layout


By : micheal.liu
Date : March 29 2020, 07:55 AM
I wish did fix the issue. display:grid; allows you to create columns and also rows.
You need to define a grid of 12 columns and set up classes to span so many rows and so many columns, so alike bootsrap classes you can size your element within from 1th to 12th bits of a row, but , unlike bootstrap, it allows you also to span element through rows without extra markup/inbrication:
code :
.grid {
  margin: 1em;
  border: solid lightgray;
  background: lightgray;
  display: grid;
  grid-template-columns: repeat(12, 1fr);
  grid-gap: 2px;
  counter-reset: div;
}

.grid div {
  border: solid;
  text-align: center;
}

.grid div:before {
  counter-increment: div;
  content: 'N°' counter(div);
}

.grid div[class]:after {
  display: block;
  text-align: center;
  background: lightblue;
  content: "Class applied : "attr(class);
  color: crimson;
}


/* spanning cols, complete values missing */

.col-2 {
  grid-column: auto/span 2;
}

.col-3 {
  grid-column: auto/span 3;
}

.col-6 {
  grid-column: auto/span 6;
}

.col-8 {
  grid-column: auto/span 8;
}


/* spanning rows , complete values missing*/

.row-2 {
  grid-row: auto/span 2;
}
<div class="grid">
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
</div>
<div class="grid">
  <div class="col-3"></div>
  <div class="col-3"></div>
  <div class="col-3"></div>
  <div class="col-3"></div>
  <div class="col-6"></div>
  <div class="col-6"></div>
  <div class="col-2 row-2"></div>
  <div class="col-8"></div>
  <div class="col-2 row-2"></div>
  <div class="col-3"></div>
  <div class="col-2"></div>
  <div class="col-3"></div>
</div>

Why does a grid item with a grid-area name, but not defined in grid-template-areas, create an additional column?
