Win2D | use Windows Runtime API for immediate mode 2D graphics | Runtime Evironment library

I'm having performance issue when I copy the data from input (ReadOnlySpan) to output (Span) using (Loops like 'for')

there is Span.CopyTo, it's perfect and very fast but for now it's useless without converting the pixels.

below is the code, I have feeling that there is some short way to do that instead of the current process:

I am trying to create a MSTest project for unit testing of our WinUI 3 development. I am able to run tests through the test explorer when targeting .NET 5.0.

Project Reunion requires net5.0-windows10.0.19041 as the target framework. When I try to run tests targeting net5.0-windows10.0.19041 the project builds but the tests do not run. The output of the Test log below says the WinUI3-UnitTests.dll file is not found but WinUI3-UnitTests.dll does exist in the specified location.

I am new to HLSL and is trying to compile a simple test with HLSL Helpers However, it doesn't compile. I want to compile shader for my Win2D UWP app.

The code:

I'm trying to create an SVG file from some shape objects(path geometries, ellipses etc.) drawn on XAML canvas controls (the canvases are rendered on top of each other inside grid controls). It looks like Win2D can provide the classes to generate the SVG file, but I'm struggling to figure out how to populate the CanvasSvgDocument class with the shapes.

This is the only partial example I've found, but the answer seems to include a conversion to XML strings to load into the CanvasSvgDocument which seems like doing the same task twice (as SVG files are XML). Is anybody able to provide an example of how I might do this?

My current best guess of what the resulting code might look like is:

Can anyone tell me how I can get lists of all installed fonts in c# uwp? I just want to put those fonts in combo box. So, I just need a list that has all the installed fonts of the PC.

I also tried to use Win2D but it gave me null output. My code:

What I'm trying to do in a UWP app with Win2D: User pressed a button to add an image and picks their file. That file gets loaded as a resource for a Canvas Control. The image then gets rendered to the current drawing session

When the button is clicked:

In my project i would like to do a special kind of plot in Win2D. For this i need a procedure to overwrite geometries in the bitmap with new geometries, without losing the complete information of the previous geometries. The CanvasBlend.Min function seems to be the way to go.

I tried the following code, but the min function does not work as expected. It does not compare the geometry of the bitmap with the new geometry.

I'm developing a UWP application using Win2D, where I want to place certain text inside a Rect (rectangle) of defined width and height. If the text exceeds the width of the Rect then I want to clip the text with respect to the Rect's width. Here I want to show the text that fits the Rect and also the one that is getting clipped. How to do that in CanvasTextLayout in Win2D using C#?

I'm creating a uwp app where text a user types in is converted into a video overlay. The user loads the video, types in their text, gets a preview of the video with the text, then they can save their video with the overlay. Right now it works with an image overlay, but not text. I'm trying to use win2d to format the text. However, I can't figure out how to get the win2d canvas control into a windows.media.editing media clip.

I thought I could go CanvasControl > Bitmap of some sort > Image > MediaClip, but media clips can only be created through storage files or direct 3d surfaces. Anything would be helpful! This is my first time trying to write something outside of a game engine.

The part that currently converts the canvas control to a bitmap:
