This question already has an answer here: Displaying SVG in OpenGL without intermediate raster 5 answers Is there a way to load a vector graphics file and then render it using OpenGL? This is a vague question as I don't know much about file formats for vector graphics. I know of SVG, though. Turning it to raster isn't really helpful as I want to do real time zooming in on the objects. Let me expand on Greg's answer. It's true that Qt has a SVG renderer class, QSvgRenderer. Also, any drawing that you do in Qt can be done on any "QPaintDevice", where we're interested in the following "paint

Please tell me what libraries for drawing and handling of vector graphics within HTML5 Canvas do you know? Thank you!!! expiredninja There are a few options. I haven't used either of these libraries, but from what I can tell Cake seems generally more impressive, and imported, while also being three times as large. There is also the Burst Engine, currently an extension of processing.js, which is even smaller. I'm sure there are several more out there. Processing.js "Processing.js is the sister project of the popular Processing visual programming language..." size: 412 KB Raphael "Raphaël is a

I need to draw concentric arcs of various sizes using raphael.js. I tried to understand the code behind http://raphaeljs.com/polar-clock.html , which is very similar to what I want, but, whithout comments, it is quite difficult to fathom. Ideally, I would need a function that creates a path that is at a given distance from some center point, starts at some angle and ends at some other angle. genkilabs That answer is ok, but cant be animated. I ripped the important stuff out of polar-clock for you. Here is a red arc that animates growing. enjoy. // Custom Arc Attribute, position x&y, value

I'm a newbie to both R and LaTeX and have just recently found how to plot a standard time series graph using R and save it as a png image. What I'm worried about is that saving it as an image and then embedding it into LaTeX is going to scale it and make it look ugly. Is there a way to make R's plot() function output a vector graphic and embed that into LaTeX? I'm a total beginner in both so please be gentle :) Code snippets are highly appreciated! Dirk Eddelbuettel Shane is spot-on, you do want Sweave. Eventually. As a newbie, you may better off separating task though. For that, do this: open

In one of my projects I use JUNG2 to visualize a very large multiple-parent hierarchy graph, displayed in an applet. I would need to export the whole/parts of the graph to high resolution still images, since screenshots look hideous when printed (especially if the graph has been zoomed out). The code I use currently is as follows: public void writeToDisk(File saveToFolder, String filename) { //Dimension loDims = getGraphLayout().getSize(); Dimension vsDims = getSize(); int width = vsDims.width; int height = vsDims.height; Color bg = getBackground(); BufferedImage im = new BufferedImage(width

I would like to be able to use vector graphics, preferably defined in XAML, as the Source of an Image control, just like I can currently use a raster image like a PNG. That way I could easily mix and match between bitmap and vector images, like this: <StackPanel> <Image Source="Images/Namespace.png"/> <Image Source="Images/Module.xaml"/> </StackPanel> Module.xaml would most likely have <DrawingImage> as its root element instead of <UserControl> . Actually, what I'm really going for is this, so my ViewModel could select either a raster or vector image at its discretion: <Image Source="{Binding

With the new android support update, vector drawables get backward compatibility. I have a vector image with various paths. I want the color of the paths to change on click of a button or programmatically based on an input value. Is it possible to access the name parameter of the vector path? And then change the color. Use this to change a path color in your vector drawable VectorChildFinder vector = new VectorChildFinder(this, R.drawable.my_vector, imageView); VectorDrawableCompat.VFullPath path1 = vector.findPathByName("path1"); path1.setFillColor(Color.RED); Library is here: https://github
