UWP Tile not showing svg image - .net-core
Following code for a Tile on windows 10 start menu shows a '.png' image that I created using MS Paint. But the same code does not show a similar .svg image (in the Tile) that I created using InkScape.
Question: Why the same code does not work for .svg image while it works for .png image - and how can we make it work for .svg images, as well?
Snapshot of Start menu with a Tile display with .png file:
Code:
public void TileTest()
{
// Construct the tile content
TileContent content = new TileContent()
{
Visual = new TileVisual()
{
TileWide = new TileBinding()
{
Content = new TileBindingContentAdaptive()
{
Children =
{
new AdaptiveGroup()
{
Children =
{
new AdaptiveSubgroup()
{
HintWeight = 2,
Children =
{
new AdaptiveImage()
{
//NOTE: if I replace Test.png with Test.svg image, it
//does not show up
Source = "Images/MyImages/Test.png",
HintRemoveMargin = true
}
}
}
}
},
}
}
}
}
};
TileNotification notification = new TileNotification(content.GetXml());
TileUpdateManager.CreateTileUpdaterForApplication().Update(notification);
}
Remark: It may not matter, but just in case: I'm using a Packaged WPF app that is calling UWP/WinRT APIs - using VS2019 - ver 16.9 and .NET5 on Windows 10 Pro - ver 2004.
Following are the .png and .svg Images I tried on the above code. .svg did not show up in the tile:

SVG with marker having an issue on mouse over
I have a button with svg inside like: <button> Checkout <ArrowSvg /> </button> And ArrowSvg looks like this (line has class: svg-line): <svg fill="none" stroke="#000"> <defs> <marker id="m" overflow="visible"> <path d="M-4,-4L0,0 -4,4" /> </marker> </defs> <line x1="0" y1="50%" x2="100%" y2="50%"marker-end="url(#m)" class="svg-line" /> </svg> When button is hovered, I change the stroke color: btn:hover > .svg-line { stroke: blue; } It's working well - when I hover the button, the arrow (line and arrow head) turns blue. But when I display the multiple buttons (more than 1), hovering 1 button affects arrows in other buttons. The arrow head part (which is marker/path in svg?) of all the buttons get affected when hovering the first button. I am also working with the arrow width, so I need line. I can't make everything with path because I won't be able to expand the arrow width. Am I missing anything? Why am I seeing this issue?
Wrap it in a native JS Web Component, supported in all modern browsers, to create the <svg> because every SVG requires a unique marker ID note: the SVG is created for every instance, no need for a marker at all, use the path by itself customElements.define("svg-button",class extends HTMLElement{ connectedCallback(){ let id = "id" + (Math.floor(Math.random() * 1e10)); let stroke = this.getAttribute("stroke") || "#000"; this.innerHTML = ` <button> Checkout <svg fill="none" stroke="${stroke}" viewBox="0 0 10 10"> <defs> <marker id="${id}" overflow="visible"> <path d="M-4,-4L0,0 -4,4"/> </marker> </defs> <line x1="0" y1="5" x2="9" y2="5" marker-end="url(#${id})"/> </svg> </button>` } }); <style> button:hover svg { stroke:gold; } </style> <svg-button></svg-button> <svg-button stroke="red"></svg-button> <svg-button stroke="green"></svg-button> <svg-button stroke="blue"></svg-button>
What you are writing looks like .JSX syntax, but the question is lacking a react tag. I will assume it for this answer anyway, but other frameworks using the format will probably work comparably. All you need is a unique id for the <marker> element. This is easily done if you spell out the <ArrowSvg> as a function. Then, wrap it in a factory function to form a closure over a running number: const ArrowSvg = (() => { let id = 0; return function (props) { return ( const ref = 'arrowMarker' + ++id; <svg fill="none" stroke="#000"> <defs> <marker id=(ref) overflow="visible"> <path d="M-4,-4L0,0 -4,4" /> </marker> </defs> <line x1="0" y1="50%" x2="100%" y2="50%" marker-end=(`url(#${ref})`) class="svg-line" /> </svg> ); } })();
Having many SVG DomMarkers in HERE maps causes lag
I'm using HERE maps 3.0 (also tried 3.1 and have the same issue) with the default layers in an angular project. The map has DomMarkers using a complex SVG icon with many paths inside a div. I noticed that adding many markers (over 200) causes a lag when zooming or moving around the map. I'm using SVG instead of static image files to be able to change the colour and modify the shape of the icon before adding it to the map. Using a dom icon with multiple divs shaped with CSS instead of the SVG, results in the same lag. If I use a more simple SVG or a simple div, the lag is reduced significantly. What's causing the lag? Is it caused by the complexity of the SVG, or the large and many paths it has? Is there a way to have complex SVG markers and eliminate the lag?

The lag is happening not while loading the markers, but when trying to move around the map or zoom in and out. It's very laggy especially when zoomed out and many markers are visible. adding the group in the map: this.map.addObject(this.markerGroup); adding a marker: addMarker(data) { const id = data.id; if (!mapObjects[id]) { let coords; coords = { lat: data.lat, lng: data.lon }; const icon = new H.map.DomIcon(this.createMarkerIcon(data)); this.mapObjects[id] = new H.map.DomMarker(coords, { icon: icon }); this.mapObjects[id].setData(data); this.markerGroup.addObject(this.mapObjects[id]); } else if (this.markerChanged(data)) { this.updateMarker(data); } } loop that adds the markers: markers.forEach(markerData => { this.addMarker(markerData); }); edit: svg added, snippets added
Caching could help you to avoid this zoom out lag. reading larger marker data again and again with complex svg making it laggy. you can try to store the markers in one variable and cache it if the data is not changing all the time, like below var testObject = { 'one': 1, 'two': 2, 'three': 3 }; // Put the object into storage localStorage.setItem('testObject', JSON.stringify(testObject)); // Retrieve the object from storage var retrievedObject = localStorage.getItem('testObject');
The problem was that I used H.map.DomMarker instead of H.map.Marker and the many html elements caused the map to lag. H.map.Markers are rendered on the map and don't cause zooming and moving lag.

Here are some hints, tells you more about svg: http://edutechwiki.unige.ch/en/Using_SVG_with_HTML5_tutorial Youtube is full of howto's with inkscape. So in this case: 1. search youtube first 2. google 3. should search most of your issues with using inkscape - its easy to use editor. NOTE: Maybe try to save some svg image and look how it looks like inside (using pspad or notepad++ or whatever text editor).
Using an svg image with inline data uri
I'm pretty sure this isn't possible, but before giving up I wanted to throw it out there. Here's a fiddle, http://jsfiddle.net/sqszuzep/6/ <svg version="1.1" viewBox="0 0 2 1" width="100%"> <image xlink:href="http://fillmurray.com/600/300" x="0" y="0" height="100%" width="100%"/> </svg> <div id="bg" class="bg"></div> <div id="bg2" class="bg"></div> <h2>IE10/11</h2> <div id="bg3" class="bg"></div> <div id="bg4" class="bg"></div> js: // Chrome/Firefox/Safari var x = encodeURIComponent('<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 400 400"><circle fill="#000000" stroke="#000000" stroke-width="20" cx="105" cy="105" r="90"></circle> <circle fill="none" stroke="#0000FF" stroke-width="10" cx="300" cy="105" r="90"></circle></svg>'); var y = encodeURIComponent('<svg version="1.1" viewBox="0 0 2 1" width="100%"><image xlink:href="http://fillmurray.com/600/300" x="0" y="0" height="100%" width="100%"/></svg>'); $(function () { $('#bg').css('background-image', 'url("data:image/svg+xml;utf8,'+ x +'")'); $('#bg2').css('background-image', 'url("data:image/svg+xml;utf8,'+ y +'")'); }); // IE 10/11 // Chrome/Firefox/Safari var x = btoa('<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 400 400"><circle fill="#000000" stroke="#000000" stroke-width="20" cx="105" cy="105" r="90"></circle> <circle fill="none" stroke="#0000FF" stroke-width="10" cx="300" cy="105" r="90"></circle></svg>'); var y = btoa('<svg version="1.1" viewBox="0 0 2 1" width="100%"><image xlink:href="http://fillmurray.com/600/300" x="0" y="0" height="100%" width="100%"/></svg>'); $(function () { $('#bg3').css('background-image', 'url("data:image/svg+xml;base64,'+ x +'")'); $('#bg4').css('background-image', 'url("data:image/svg+xml;base64,'+ y +'")'); }); Essentially I was attempting to use a svg image, encode the svg element and use it in css on an element. This works for vectors, but not for images loaded via svg. I believe this pertains, https://bugs.webkit.org/show_bug.cgi?id=63548 saying that "Images are not allowed to load further resources". What I see is that no browser supports this feature, or I'm doing something wrong. It is possible to base64 encode image data and use that, as demonstrated in this fiddle I wrote: http://jsfiddle.net/N2n27/3/. On browsers that support svg filters (non-IE) this is a handy way to do blurring and other filter effects. Am I missing something here?
There are two issues with the y version. a) the svg element has no namespaces (it does in the x version) but in the y version it also needs the xlink namespace as the image href attribute is in the xlink namespace. b) the image in the SVG is external. A css background is an image itself so any SVG it references cannot load external resources. You therefore need to URI encode the inner image data and then uri encode the outer SVG (thereby doubly encoding the inner image data) So you need something like this... var y = encodeURIComponent('<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" viewBox="0 0 2 1" width="100%"><image xlink:href="data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEASABIAA.... Which I've completed here for the Firefox/Chrome case
How To Generate SVG using MVC Razor
We am trying to make an SVG generated radio button control for my MVC3 application. Ideally, the control would be a partial view and we would pass in a model which would contain data on how to generate the SVG using Razor. We have tried to write the SVG into Razor normally, but we get nothing but compile errors. How can we generate SVG using MVC3 Razor? The error is: Expression Must Return a Value To Render EDIT: The error is not coming from within the partial view, but when we call #Html.RenderPartial("SvgRadioButtonControl", ((IResponseLabeledItem)Model).ResponseOptions) it gives the error. #using SmartQWeb.Models.Entities #model IEnumerable<ResponseOption> <svg xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" version="1.1" width="300" height="400" id="radio"> <script type="application/ecmascript"><![CDATA[ var innerCircleExpandedSize = 11; function ResponseOptionClicked(evt) { console.log('Response option clicked'); // Remove circle in enabled element var enabledElem = document.getElementsByClassName('enabled')[0]; if (enabledElem != undefined) { console.log('Removing a inner circle'); enabledElem.getElementsByClassName('response-innercircle')[0].setAttribute('r', 0); enabledElem.className.baseVal = enabledElem.className.baseVal.replace('enabled', 'disabled') } // Add circle in radio button console.log('Adding a inner circle'); evt.currentTarget.getElementsByClassName('response-innercircle')[0].setAttribute('r', innerCircleExpandedSize); evt.currentTarget.className.baseVal = evt.currentTarget.className.baseVal.replace('disabled', 'enabled'); } ]]></script> <g id="base"> #{ int iteration = 1; } #foreach (ResponseOption option in Model) { <g id="response-never" class="response-option disabled" transform="translate(50,#{ (iteration++ * 1).ToString(); })" onclick="ResponseOptionClicked(evt)" fill="#ffffff"> <circle class="response-outercircle" r="18" stroke="#000000" stroke-width="3" stroke-miterlimit="4" stroke-opacity="1" stroke-dasharray="none" /> <circle class="response-innercircle" r="0" fill="#000000" stroke="#000000" /> <text x="40" y="6.5" font-size="1.5em" fill="blue" class="response-text">#option.Label</text> </g> } </g> </svg>
Replace: #Html.RenderPartial("SvgRadioButtonControl", ((IResponseLabeledItem)Model).ResponseOptions) with: #{Html.RenderPartial("SvgRadioButtonControl", ((IResponseLabeledItem)Model).ResponseOptions);} or if you prefer: #Html.Partial("SvgRadioButtonControl", ((IResponseLabeledItem)Model).ResponseOptions) Also the following expression in your partial just stinks: #{ (iteration++ * 1).ToString(); }) Didn't you mean: #(iteration++)
