如何设置 OpenTK window 图标

Question

I've tried looking around and I cant figure out how to set the top-left window Icon for an OpenTK gameWindow, I'm using C# and I'm trying to set the icon to a image file on my computer.

My IDE is Visual Studio Code.

Answer 1

if you go to Project > (projectname) Properties > Application

you should see a section for setting your icon

if this section is blurred out

then open the.csproj file and add <ApplicationIcon>Path/to/file</ApplicationIcon>

in the <PropertyGroup> section.

Answer 2

You can set the GameWindow icon by using the NativeWindowSettings.Icon property.

var nativeWindowSettings = NativeWindowSettings.Default;
nativeWindowSettings.Icon = new WindowIcon(width, height, data); // data is a byte[]

If you want a more concrete example, I'm using ImageSharp to actually load the image and create the WindowIcon :

public static WindowIcon CreateWindowIcon()
{
    var image = (Image<Rgba32>)Image.Load(Configuration.Default, "./Assets/Images/Logo.png");
    image.TryGetSinglePixelSpan(out var imageSpan);
    var imageBytes = MemoryMarshal.AsBytes(imageSpan).ToArray();
    var windowIcon = new WindowIcon(new OpenTK.Windowing.Common.Input.Image(image.Width, image.Height, imageBytes));

    return windowIcon;
}
