Clip div with SVG path

阅读更多关于 Clip div with SVG path

问题 I have two overlapping divs and I am trying to achieve the following effect: In order to do that my logic is to get the two divs to overlap, create that shape with SVG inside the second div and use that shape to clip the second div and show what’s below it (the top div). I’m not sure if this is the best logic to follow to achieve this and if it is I’m not sure how to use the SVG to clip the HTML element. This is my HTML so far: <div class="banner_1"> </div> <div class="banner_2"> <svg viewBox

HTML5 Canvas ctx.clip() method used on a circle leaves a line underneath the circle

阅读更多关于 HTML5 Canvas ctx.clip() method used on a circle leaves a line underneath the circle

I've created a program to generate planet sprites. I'm doing that by creating a circular path, running ctx.clip() to keep all the following layers inside of the circle, then drawing a black and transparent texture layer, then a randomly colored rectangle over the full canvas, then a shadow and glow on top of it all. The issue is that a colored line also appears under the circle after clipping, and I'm not sure why. I need this removed. Here is a fiddle. The last line sets the code to loop every half second: https://jsfiddle.net/tzkwmzqu/4/ I am not sure I do understand your problem, but I will

Java play multiple Clips simultaneously

阅读更多关于 Java play multiple Clips simultaneously

So my application should play the WAV file every time I click on the panel. But the problem right now is, it waits for the first one to finish before it plays the second one. I want to be able to have them play simultaneously. The reason I put Thread.sleep(500) is because if I don't, then it won't play the sound at all :( import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.io.IOException; import java.net.MalformedURLException; import java.net.URL; import javax.sound.sampled.AudioInputStream; import javax.sound.sampled.AudioSystem; import javax.sound.sampled.Clip;

How to distort an image to any quadrangle?

阅读更多关于 How to distort an image to any quadrangle?

问题 Do any of you have an idea, how to distort an image in any quadrangle? I want to implement an image, which you can pull any corner in any direction, distorting the image. Anyone has an idea how to do that? I use and write stuff in android for a while now, but it does not seem like android has a function for that. I don't really feel like writing a new math library :). Greetings, Can 回答1: Looks like you need Canvas.drawBitmapMesh . There is a sample in Android SDK showing how to use it. You

Spritesheet in Silverlight

问题 Does anyone have an example of using a spritesheet in Silverlight? I'd like to clip the image and, when a button is pressed, jump to the next frame. (If the user keeps tapping the button, it'll look like an animation). I've looked around but haven't found exactly what I'm looking for. Thanks for any help. 回答1: The following will do exactly what you're looking for. You can use the Up ↑ and Down ↓ keys on your keyboard to navigate forwards and backwards through the animation.

How to render clipped surfaces as solid objects

阅读更多关于 How to render clipped surfaces as solid objects

In Three.js, I have a 3d object where I am using local clipping planes to only render a part of the object. However, since 3d objects are "hollow" (meaning only the outer surface is rendered), when we clip anything off that surface we can "see into" the object. Here's an example of what I mean, clipping a corner off a cube . Notice how we can see the backside of the opposite corner. I would like to give the appearance of the object being solid. Based on this issue , it seems that the best way to accomplish this is to create a surface over the clipped region, thus capping the hole and making

Clip values between a minimum and maximum allowed value in R

阅读更多关于 Clip values between a minimum and maximum allowed value in R

问题 In Mathematica there is the command Clip[x, {min, max}] which gives x for min<=x<=max , min for x<min and and max for x>max , see http://reference.wolfram.com/mathematica/ref/Clip.html (mirror) What would be the fastest way to achieve this in R? Ideally it should be a function that is listable, and should ideally work on either a single value, vector, matrix or dataframe... cheers, Tom 回答1: Rcpp has clamp for this: cppFunction('NumericVector rcpp_clip( NumericVector x, double a, double b){

Clipping raster using shapefile in R, but keeping the geometry of the shapefile

阅读更多关于 Clipping raster using shapefile in R, but keeping the geometry of the shapefile

问题 I am using {raster} to clip (or crop) a raster based on an irregular shapefile (the Amazon biome) but the output always has a rectangular extent. However, I need the output in the exact same geometry of the shapefile. Any tips? Cheers. library(raster) library(rgdal) myshp <- readOGR("Amazon.shp", layer="Amazon") e <- extent(myshp) myraster <- raster("Temperature.tif") myraster.crop <- crop(myraster, e, snap="out", filename="myoutput.tif") 回答1: One option is to use raster::mask() library

Component painting outside custom border

阅读更多关于 Component painting outside custom border

问题 In this custom border class, I define a RoundRectangle2D shape. This object is used to paint the border. Unfortunately, since the paint method of a JComponent invokes paintComponent before paintBorder , setting the Graphics clip to the RoundRectangle2D shape has no effect; even if I issue a repaint . Therefore, the component will paint outside it's border, which is understandably undesirable. So, I was wondering: how do I get the component to paint exclusively inside a custom border? One
