edges

When drawing polygons, Java2D leaves off the right and bottom edges. I understand why this is done. However, I would like to draw something that includes those edges. One thing that occurred to me was to follow fillPolygon with drawPolygon with the same coordinates, but this appears to leave a gap. (See the little triangular image at the bottom.) There are two possibilities, but I can't tell which. To enable antialiasing, I'm doing this: renderHints = new RenderingHints(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); renderHints.put(RenderingHints.KEY_RENDERING,

I'm working with igraph for R. My graph is based on an edgelist which includes parallel edges (more than one edge with the same source and target). I would like to convert these parallel edges to an edge attribute weight. Is there an eay way to do this? If there is no easy way. how can I identify these parallel edges? duplicated(E(net)) does not return a single duplicate. I suppose its looking for duplicated edge ids. You can also use E(graph)$weight <- 1 followed by simplify(graph, edge.attr.comb=list(weight="sum")) to assign a weight of 1 to each edge and then collapsing multiple edges into

How would I create a graph, such that the property map (weight of edges) is different in each property map? Is it possible to create such a property map? Like an array of property maps? I have not seen anyone on the Internet using it, could I have an example? Graph g(10); // graph with 10 nodes cin>>a>>b>>weight1>>weight2>>weight3>>weight4; and put each weight in a property map. You can compose a property map in various ways. The simplest approach would seem something like: Using C++11 lambdas with function_property_map Live On Coliru #include <boost/property_map/function_property_map.hpp>

I have a triangle ( JSFiddle ) using this CSS: .triangle { width: 0; height: 0; border-top: 0; border-bottom: 30px solid #666699; border-left: 20px solid transparent; border-right: 20px solid transparent; } And this HTML: <div class="triangle"></div> This makes a triangle, but the diagonal lines are jagged and pixelated. How can I make them smooth? (I was able to smooth them out in Safari and Chrome by making them dotted, but that broke the triangles in Firefox and IE.) Even in pure CSS we can get the smooth diagonals. .triangle { width: 0; height: 0; border-top: 0; border-bottom: 30px solid

Is it possible to refine or blur just the edges in an image with the white background ? I was thinking to get an edge mask of the image ( i already got it). After that use that mask to apply blur or smoothing function on the original image. So that only the edges will be blurred or refined. But i don't know how to achieve this. Thanks If you have an edge mask of the image, do that: Dilate(edgemask) Copy(source: original, destination: blurred) Smooth(blurred) Copy(source: blurred, destination: original, mask: edgemask) And your "original" image will be blurred. 来源： https://stackoverflow.com

digraph G { a -> b [ label = "foo" ]; a -> b [ label = "bar" ]; } This will create two edges between the 'a' and 'b' nodes. Is there a way to have only one edge (group them)? I think it really depends on what your desired output would be. One possibility is: digraph G { graph [ splines = false ] a -> b [ label = "foo" ]; a -> b [ label = "bar" ]; } Where not using splines draws edges with straight line segments and so duplicate edges will not be distinguished visually. In your ideal output, what would the single edge look like since there are to be two different labels for it? The "strict"

How to round edges in picturebox control. I Want to get angles like ellipse have but i dont know how to do it. I Use C#. Thanks! Yes, no problem, you can give a control an arbitrary shape with its Region property. Add a new class to your project and paste the code shown below. Compile. Drop the new control from the top of the toolbox onto your form. using System; using System.Drawing; using System.Drawing.Drawing2D; using System.Windows.Forms; class OvalPictureBox : PictureBox { public OvalPictureBox() { this.BackColor = Color.DarkGray; } protected override void OnResize(EventArgs e) { base
