shape

问题 I want to use a background for my buttons. But when I use a png it slows down the app. Therefore I want to use a xml shape but I do not know how to make the corner cut (like on the picture). By now I have the following shape which is just a rectangle: <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"> <solid android:color="@color/blue_semi_transparent"/> <padding android:bottom="10dp" android:right="10dp" android:top="10dp" android:left=

问题 I'm in no way a professional programmer so, pls don't expect a sophisticated approach or language here. I'll however appreciate your advice and recommendations to materialize an algorithm which, at a later stage, I could programmatically add to my project... Here is the problem: Imagine an arbitrary point (Point X) in space with the following properties: has coordinates lies on a 2D-surface is stationary belongs to a single area (boundary coordinates of which are also known) at any given time

问题 I'm trying to make a triangle in CSS that takes the whole width of the parent with a fixed height. I successfully did so with a linear-gradient like this: .triangle { width: 100%; height: 120px; background: linear-gradient(to right bottom, blue 50%, transparent 50%); } <div class="triangle"></div> But the diagonal doesn't look crisp. How could I do the same in CSS without using gradient? 回答1: You can blur the edge a bit .triangle { width: 100%; height: 120px; background: linear-gradient(to

问题 Is it possible to keep the chart style (shape styles) from a xlsx file when I read and write it? With my code below the style is lost . require 'vendor/autoload.php'; use PhpOffice\PhpSpreadsheet\Spreadsheet; use PhpOffice\PhpSpreadsheet\Writer\Xlsx AS WXlsx; use PhpOffice\PhpSpreadsheet\Chart\Chart; use PhpOffice\PhpSpreadsheet\Settings; use PhpOffice\PhpSpreadsheet\Reader\Xlsx; echo "Opening file...<br>"; $spreadsheet = new Xlsx(); $spreadsheet->setIncludeCharts(true); $spreadsheet =

问题 I want to find custom shape in OpenCV. Shape is previously defined. I want to detect if this shape is equal or not equal to the current shape using WebCam in real time. How can I do that? How to compare pre-defined custom shape and current shape? 回答1: As the commenters have eluded, you can use template matching to detect custom shapes. So What Is Template Matching? Template matching is a technique in digital image processing for finding small parts of an image which match a template image. It

问题 So I created a really naive (probably inefficient) way of generating hasse diagrams. Question: I have 4 dimensions... p q r s . I want to display it uniformly (tesseract) but I have no idea how to reshape it. How can one reshape a networkx graph in Python? I've seen some examples of people using spring_layout() and draw_circular() but it doesn't shape in the way I'm looking for because they aren't uniform. Is there a way to reshape my graph and make it uniform? (i.e. reshape my hasse diagram
