@grokys @danwalmsley was right. I set xaml.cs file to compile, and remove compile option from xaml and it work. If you need i may upload my repository again
I am wondering how do I join the project/become contributor?
@bleepzter best place to start is here! what are you interested in doing?
Every single Cs file is explicitly set to compile
If you add a new Cs file to the project you have to manually add another entry in the csproj file
i thought you were talking about the csprojs from the templates
Hey all -- random question. Is there any way to accomplish something like AvaloniaUI/Avalonia#6 at the moment? It would be cool to be able to embed a "Veldrid widget" into an app. I have a general feel for what it would look like in theory, but I'm not sure what's exposed from Avalonia
If there's anything like this SDL2 function then I think I'd understand how it would work
interested in doing something like that myself, though I have no idea where to even begin
A question, I saw that Avalonia is using different backend for rendering (gtk on linux). Have you considered using Vulcan lowlevel 3d API? As I understand its supported (or will be) by Linux, Windows and Mac. Now with Wayland I think also all 3 OS are using Display Servers? Couldn't this simplify the architecture and minimize OS specific code?
Didn't WPF use DirectX as backend? so Vulcan would be very similar...
@mellinoe does https://github.com/AvaloniaUI/Avalonia/tree/master/samples/interop/Direct3DInteropSample do something like what you want?
@Weboholics we need a 2D drawing library, not a 3D library. we curerntly use skia and direct2d. if skia were to support vulcan then we'd get support automatically
oh in fact looks like it already does: https://github.com/google/skia/blob/master/site/user/special/vulkan.md
so yeah we should have vulkan support already i guess
For Vulkan support we might have to set some settings on Skia to use GPU acceleration.
Skia now has a WebAssembly backend so Avalonia could be compiled to wasm and statically linked to it. I am talking BS, or does that sound feasible?
Best way to do 2D drawing is using the 3D Graphics from what I have heard :-) . My idea was that using Vulkan for rendering would decrease OS dependent code and enable fast and efficient animations and effects. Of course you could combine this with some high level library like skia. If I am not wrong all major OS now separate rendering from presentation (Display server).
@Weboholics yes that is exactly what skia does - 2D drawing using 3D graphics APIs ;)
There are some project that tries to implement 2d graphics on the top of vulkan api like https://github.com/jpbruyere/vkvg but it will take years to reach skia/cairo level

@grokys I am getting this error when using
netcoreapp2.0 with UseDirect2D1()
Using
UseSkia() works fine. Is this know issue?
@wieslawsoltes there is a problem with using sharpdx on netcoreapp which is AvaloniaUI/Avalonia#1320
not sure if you're seeing the same problem or not though
The app runs ok, the exception is thrown only when using drawing context
are you drawing bitmaps?
let me take a look at that code
@wieslawsoltes ah yeah looks like a simple mistake i introduced in jan
fix incoming
Just checked my code and indeed I was passing pen as null in some cases.
@grokys Interesting. although it's a bit Windows and D2D-specific. I was thinking of something along the lines of an "EmbeddedNativePanel" that would let you hook your own renderer into it, and would be cross-platform. I have to admit I have no idea whether that would be possible outside of Windows, though.
yeah, i suspect achieving that cross-platform would be a bit difficult
@grokys I have found some issues on the border thickness branch posting details
@danwalmsley Did you try to improve text quality when using Skia backend?
The text sharpness is much worse when using Skia.
but only managed to make minimal improvement
@grokys By the way just refactored some code to use
Bind Commands to Methods and its so nice!
at somepoint there was a regression but never got chance to look at it
@jkoritzinsky
Bind Commands to Methods is so great! Thanks!
@grokys issue was in one of my styles I had
<sys:double x:Key="ThemeBorderThickness">2</sys:double>
had to change to Thickness
so I think that branch looks good
@danwalmsley The skia text rendering sharpness needs definitely improvement
let me know if you find any problems with corner radius
@wieslawsoltes I think when I looked at it the main improvement was setting LCDRendering or something of similar naming to true
@wieslawsoltes post a screen shot of the text you are seeing? so I can see we are talking about the same thing
Seems like this is already set here
yeah that's what I see, I put it down to skia not being able to take advantage of clear type?
that was my theory anyway
That corner radius =4 border thickness =1
could be textblock causing it
@wieslawsoltes hmmm looks interesting, so they render it at higher dpi then scale down
AvaloniaUI/Avalonia@ead7b3b
hmmm, I guess that was when text was visible through layers when it shouldn't have been, that didn't make the text perfect btw
just a little better
fixes a minor crash
Can you please explain what is working strange with textblock?
