I'm trying to create a surface from an OpenGL texture, and I'm trying to use an already existing OpenGL context (created by OpenTK's GameWindow).

I didn't really find any documentation on how to do that. I saw a test for GRGlInterface.AssembleGlInterface here: https://github.com/mono/SkiaSharp/blob/master/tests/Tests/GRGlInterfaceTest.cs, so I tried to use similar code for getting the existing context, no clue if that's how you actually should go about it.
I didn't find anything on how to use CreateAsRenderTarget so I tried to guess.

This is the code I used (currently on Mac only)

    public class SkiaSurface
    {
        private GRContext _context;
        private int _texture;

        public static int Texture;

        public void Load()
        {
            var lib = MacDynamicLibraries.dlopen("/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib", 1);

            var glInterface = GRGlInterface.AssembleGlInterface((context, name) => {
                return MacDynamicLibraries.dlsym(lib, name);
            });

            bool b = glInterface.Validate();
            Debug.Assert(b);

            _context = GRContext.Create(GRBackend.OpenGL, glInterface);
            Debug.Assert(_context.Handle != IntPtr.Zero);

            _texture = GL.GenTexture();

            glInterface.Handle;
        }

        public unsafe void Draw()
        {
            GL.BindTexture(TextureTarget.Texture2D, _texture);
            fixed (int* p = &_texture)
            {
                var desc = new GRBackendTextureDesc
                {
                    Width = 500,
                    Height = 300,
                    Config = GRPixelConfig.Bgra8888,
                    Origin = GRSurfaceOrigin.TopLeft,
                    SampleCount = 0,
                    Flags = GRBackendTextureDescFlags.RenderTarget,
                    TextureHandle = new IntPtr(_texture)
                };
                using (var surface = SKSurface.CreateAsRenderTarget(_context, desc))
                {
                    ... irrelevant drawing code goes here (it crashes on CreateAsRenderTarget) ...
                }
            }
        }
    }

This is the error I'm getting (dialog box- mono crashed)

(lldb) detach

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

To reproduce:

Grab my code from this branch: https://github.com/tzachshabtay/MonoAGS/tree/SkiaSharp
From Visual Studio on Mac, run DemoQuest.Desktop. It will crash on startup.

Hi there... sorry about the delay - I had to edit the issue to show the code. It appears that angle brackets < causes major issues in the issues :)

I had a look at this and I think I found out a few things. It appears that unlike the usual backend render target, the texture render target requires 2 pieces of information:

struct GrGLTextureInfo {
    GrGLenum fTarget;
    GrGLuint fID;
};

As the description type only accepts an IntPtr, this was not very clear. In the code, they just magically cast the type and that is why you got the exception. I will investigate this to see if there is some way to strongly type the handle (the Vulkan handle has a good few members). In the mean time, you can do something like this:

// declare the handle type
[StructLayout(LayoutKind.Sequential)]
public struct GRGlTextureInfo {
    public uint Target;
    public uint Id;
}

// create the handle
var textureInfo = new GRGlTextureInfo {
    Id = (uint)textureId,
    Target = (uint)TextureTarget.Texture2D
};

// pin the handle and pass it to the description
var textureHandle = GCHandle.Alloc(textureInfo, GCHandleType.Pinned);
var textureDesc = new GRBackendTextureDesc {
    Width = textureSize.Width,
    Height = textureSize.Height,
    Config = GRPixelConfig.Rgba8888,
    Flags = GRBackendTextureDescFlags.RenderTarget,
    Origin = GRSurfaceOrigin.TopLeft,
    SampleCount = 0,
    TextureHandle = textureHandle.AddrOfPinnedObject(),
};

// create the SkiaSharp texture surface
textureSurface = SKSurface.CreateAsRenderTarget(context, textureDesc);

// free the pinned GC handle when we are done
textureHandle.Free();

Another thing I noticed was that I had to specify a texture image:

textureId = GL.GenTexture();
GL.BindTexture(TextureTarget.Texture2D, textureId);
GL.TexImage2D(TextureTarget.Texture2D, 0, PixelInternalFormat.Rgba, textureSize.Width, textureSize.Height, 0, PixelFormat.Rgba, PixelType.UnsignedByte, IntPtr.Zero);

Here is my working sample: https://github.com/mattleibow/SkiaSharpTextures

The work done in the commit will make textures much easier using the new GRGlBackendTextureDesc type:

var desc = new GRGlBackendTextureDesc {
    ...
    TextureHandle = new GRGlTextureInfo {
        Id = textureId,
        Target = GL.Texture2D
    }
};

var context = GRContext.Create(GRBackend.OpenGL);
var surface = SKSurface.CreateAsRenderTarget(context, desc);

The pinning of the struct is now done automatically.

Hi @mattleibow thank you very much for all your help. I still can't get it to work, though. Your sample shows nicely how to use skiasharp in a gamewindow (note that I had to upgrade OpenTK to 2.0 in your example otherwise it crashes, at least on mac), but it doesn't show how to actually combine normal rendering to OpenGL with skiasharp, and when I try that everything blows up.

Working from your example (I'm working against your example, haven't tried the commit) I created an example trying to combine both drawing methods, here: https://github.com/tzachshabtay/SkiaSharpTextures

I've taken the code you had in OnLoad and OnRenderFrame and refactored it to "PrepareSkia" and "DrawSkia" and then also added a "PrepareDirect" and "DrawDirect" to prepare a texture, buffer and shader and use it to draw a simple rectangle (I just use skia there to draw to a bitmap, but then draw it with glDrawElements). I've also added a "GL.Clear" call to the beginning of the render loop.

Now, if I comment out "PrepareSkia" and DrawSkia", my OpenGL rectangle appear as expected. If I instead comment out "GL.Clear", "PrepareDirect" and "DrawDirect", your skia rendering appear as expected.

If I uncomment stuff, noticed 3 problems:

  1. If I just uncomment GL.Clear (but leave PrepareDirect and DrawDirect commented), your skia rendering appears except for the text on the texture (very odd considering the green background of the texture still appears).

  2. If I uncomment everything (i.e that's how the example is currently setup), the code crashes at at (wrapper managed-to-native) SkiaSharp.SkiaApi.gr_context_flush (intptr) [0x00009] in <cf546bad13294f0f88da02ef9d3e7062>:0

  3. If I then switch the order of DrawDirect and DrawSkia, the code crashes on "Invalid Operation" from OpenGL at the first check I do on the first line on DrawDirect (and it happens on the second "tick", so it appears as something in the skia drawing is causing an OpenGL error).

I am closing this as I am not sure if skia can be mixed in with normal OpenGL drawing. I feel that this is possible, but might be better discussed on the skia forums: https://groups.google.com/forum/#!forum/skia-discuss

In addition, it will also be better to open a issue that is specifically dedicated to any issues when mixing the drawings.
