overlay

问题 I would like to display an image composed of two images. I want image rectangle.png to show with image sticker.png on top of it with its left-hand corner at pixel 10, 10. Here is as far as I got, but how do I combine the images? Image image = new Image(); image.Source = new BitmapImage(new Uri(@"c:\test\rectangle.png")); image.Stretch = Stretch.None; image.HorizontalAlignment = HorizontalAlignment.Left; Image imageSticker = new Image(); imageSticker.Source = new BitmapImage(new Uri(@"c:\test

问题 I have plotted a Seaborn JointPlot from a set of "observed counts vs concentration" which are stored in a pandas DataFrame . I would like to overlay (on the same set of axes) a marginal (ie: univariate distribution) of the "expected counts" for each concentration on top of the existing marginal, so that the difference can be easily compared. This graph is very similar to what I want, although it will have different axes and only two datasets: Here is an example of how my data is laid out and

问题 I have an android application which can playback audio/video and show pictures. For videos I want to overlay a play button on top of the preview image and also in list views.. Right now how I'm doing it is with an ImageView in xml, and then the drawable is a layer layer-list which I define programmatically because one of the images is dynamic, the play button is static of course. I want to align the play button 10px from the bottom, and centered horizontally. My ImageView is defined like this

问题 I want to show a display overlay over a video and export that video including this display. I had a look into the AVFoundation Framework, AVCompositions, AVAssets etc. but I still do not have an idea to achieve this. There is a class called AVSynchronizedLayer which lets you animate things synchrounous to the video, but I do not want to animate, I jsut want to overlay the time display into every single frame of the video. Any advice? Regards 回答1: Something like this... (NB: culled from a much

问题 Earlier today I asked Overlay a background-image with an rgba background-color. My goal is to have a div with a background-image, and when someone hovers the div, the background-image gets overlayed with an rgba color. In the answer, a solution with :after was given: #the-div { background-image: url('some-url'); } #the-div:hover:after { content: ' '; position: absolute; left: 0; right: 0; top: 0; bottom: 0; background-color: rgba(0,0,0,.5); } I now would like to have the same, but with a CSS

问题 I'd like to overlay a div (or any element that'll work) over a table row (tr tag) that happens to have more than one column. I have tried a few methods, which don't seem to work. I've posted my current code below. I do get an overlay, but not directly over just the row. I tried setting the overlay top to $divBottom.css('top'), but that is always 'auto'. So, am I on the right track, or is there a better way of doing it? Utilizing jQuery is fine as you can see. If I am on the right track, how

问题 I display thumbnails in a JPanel. When hovering over such a thumbnail, I want to display its full version in an overlay over the thumbnail. Using HTML I would just create a div with the proper positions and a high z-index, so that it overlays everything else. Is something similiar and lightweight possible with Swing? 回答1: One way is to use a tool-tip. import javax.swing.*; import java.awt.GridLayout; class ThumbTip { private static final String HTML = "<html><body>"; ThumbTip(String[] album)

问题 How would I darken (add a semi-transparent overlay) and add text to this image (but centred horizontally and vertically) as below: HTML <img src="http://luxurylaunches.com/wp-content/uploads/2014/05/uber-london.jpg" id="top" data-appear-animation="fadeIn"> CSS #top { width: 100%; height: auto; } body { margin: 0px; } Fiddle here: http://jsfiddle.net/6jf0nxd5/ 回答1: To center the text horizontaly and verticaly, you will need to wrap it in a container with text-align:center; .
