问题 I'm using Angular 7. I'm having trouble rendering data stored in my model. I have this in my src/app/app.component.ts file @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent implements OnInit { currencies: Currency[] = []; title = 'app'; apiStatus: string; constructor(private _currencySrv: CurrencyService) { } ngOnInit() { this._currencySrv.index().subscribe(currencies => { this.currencies = currencies; }); }

问题 I'm drawing two exactly same paths on top of each other to an SVG canvas. The path behind can be seen even though the other path should hide it. Here's the SVG: <svg viewBox="0 0 100 100"> <!-- BLUE PATH --> <path id="blue" d="M 50,50 m 0,-48 a 48,48 0 1 1 0,96 a 48,48 0 1 1 0,-96" stroke="blue" stroke-width="4" fill-opacity="0" style="stroke-dasharray: 302px, 302px; stroke-dashoffset: 0px;"></path> <!-- YELLOW PATH --> <path id="yellow" d="M 50,50 m 0,-48 a 48,48 0 1 1 0,96 a 48,48 0 1 1 0,

问题 I am in the design stages of a new project which will take a data set and load it into a document, then render the document around a template. The rendered file could be a data set of CSV, a PDF marketing letter, an email, ... a lot of things. The data will not be math equations, I'm simply looking at an elegant way of connecting many data sources into many documents and outputting in many templates I'm entirely in the dark here with using latex in php. Is there anything like this out there?

问题 I have a couple of HTML elements on a page. Whenever the page context is invalidated and it re-renders the elements are re-rendered with no visual cue of the selected option. If I check for the selection using $('.select1 option:selected') the selected option is returned. However, it is not rendered as selected. If it's a drop-down, then the first element shows up. If it's a multi-line select, the first (firefox) or last (chrome) element shows up with a greyed out select line on it. If I then

问题 In rails, is there a way (in a controller) to: create a file render a view or template to that file redirect_to or render another view I've tried all kinds of constructions, but keep getting the same error: Render and/or redirect were called multiple times in this action.

问题 When I generate a set of rectangular patches in a matlab figure, some of the rectangle edges are rendered curved or clipped rather than sharp, which is unwanted. This depends on the scale, zooming into the image tends to eliminate the effect. I thought this might have to do with an aliasing/compression effect. Curiously, using rectangle the problem seems to go away. Here is an example of the problem at intermediate magnification (other problems such as dashed borders which shouldn't be there

问题 I receive the following error The following classes could not be instantiated: - android.support.design.widget.FloatingActionButton Lately that problem appears every time I opened new project in Android Studio, I tried many solutions written here, like .. Rebuild and re-sync project with gradle option. Change Android rendering version. Checking updates and install latest version. None of those solutions work for me. 回答1: Try update "build.gradle (Module.app)" like this: ... dependencies {

问题 Simply put, I'm trying to draw an image (2560x2048) that is supposed to be zoomed / draged and such but the performance is very bad, because it flickers everytime I move it. I use a custom control to be able to drag the image to a new position and zoom in and out, which means it have to be flexible and fast. So, what is the easiest and best way to just draw a single image with the graphics card? Without having to initialize a thousand directX objects just for one simple purpose. Overall, the

问题 How much can this cache hold? UIElement.CacheMode = new BitmapCache(); I don't get any exception, but a blurry (jpg-ish) appearance for given absurd size ( ClipToBounds = false ): protected override void OnRender(DrawingContext context) { context.DrawLine(new Pen(Brushes.Red, 1), new Point(-1000000, -1000000), new Point(1000000, 1000000)); } MSDN say The cache functions when hardware acceleration is not available. In this case, the bitmap is rendered in software, and the maximum bitmap
