avalonia.htmlrenderer's Issues

Is there no new version preview 6 released on NuGet?

Feature required - support letter-spacing

It does not appear to support <span style='letter-spacing:0.8em;'>.

This would would be a good one to add.

Current master branch does not build

When reverting back to 5243b3f, the build works again.

Avalonia.Browser demo broken?

Hi there,

The Html renderer looks great. Really impressed running the demo desktop app.

Unfortunately - I cannot get passed the below error with the Browser app. Tried multiple browsers running on Windows 10.

Uncaught SyntaxError SyntaxError: The requested module './avalonia.js' does not provide an export named 'registerAvaloniaModule'
at (program) (localhost꞉5001/main.js:2:10)

Thanks for any help!

Cannot set style on the 'tr' tag

Tables are supported, but setting the tr tag style does nothing. Instead, the td tags must be set individually.

Feature request - support for 'text-transform'

There doesn't appear to be any support for text-transform.

Consider adding it?

Feature request - support border dotted style

It seems to support border-style:dashed, but not dotted.

I would be surprised if people still cared about all the other styles such as ridge and groove etc., but having both dashed and dotted would be nice.

Nuget package points to wrong project site

See commit which broke this: AvaloniaUI/Avalonia@b89ab8f

Does not parse "border" fully + possible margin issue

Possibly two issues here. See screenshot below.

Does not parse the tag string border:medium solid blue fully but ignores the color. However, it does parse border:medium solid;border-color:blue;.
Correct me if I am mistaken on this, but there should be no spacing between the two borders shown in the screenshot and margin is explicitly set to 0 for both.

Linux Debian 12. Avalonia 11.

Polite feature request - consider adding support for 'ch' length?

I actually have a use for the ch length unit, but can hack around its absence. Would it be worth adding support for this?

HtmlLabel and HtmlPanel are not available on v0.10

Hello. I can't seem to be able to use both HtmlLabel and HtmlPanel on v0.10. I have tested v11 and it worked fine.

When I declare a XAML namespace for the HtmlRenderer package, only HtmlContainer is shown.

Creating a fresh project, adding the 0.10 nuget package, adding the namespace and trying to find the controls result in the following:

devenv_aoXJZBqHuC.mp4

The code-behind also doesn't feature them:

And these are the contents of the namespace in v11, which is the expected:

The "AvaloniaStatsTask" task failed unexpectedly

I've cloned the repo & I'm trying to build HtmlRenderer.Demo.Avalonia.Desktop and I'm getting the following build error:

Any tips?

Plans on "reintegration" html rendering?

I am evaluating avalonia in order to create an application that can display html generated from markdown.
It seems that the HtmlControl/Rendering is currently not usable (see AvaloniaUI/Avalonia#1493).

Are there any plans to "reintegrate" that feature?

Chinese characters are garbled

This is one of my tests, the red box is Chinese, but the characters are garbled
This is bug or my fault?
How to fixed it？
Thinks for your time.

Render to Bitmap

Is it possible to render content to Avalonia Bitmap? Original project has a HtmlRender.RenderToImage that fulfills this purpose.

Another feature request - support alpha channel

Does not support alpha in colors.

This is fine: background-color:#756575;
But this is not: background-color:#756575ff; and no background is shown.

This is also fine: background-color:rgb(201, 76, 76)
But this is not: background-color:rgba(201, 76, 76, 0.3)

Consider adding it?

Discussion - center align images with HtmlRenderer

This is more of a discussion, but I was trying to centre an image with HtmlRenderer. However, it supports neither margin:auto or float.

This is merely an online note to anyone trying to do the same thing. Here's how I managed it.

HtmlPanel control

In HtmlControl.cs there is a large comment referencing HtmlLabel and HtmlPanel. There doesn't appear to be an HtmlPanel, in fact the only public class with a public constructor appears to be HtmlLabel. Is there any way to render chunk of HTML in a panel with Avalonia?

I'm looking for a cross platform equivalent to the System.Windows.(Controls|Forms).WebBrowser control - preferably one that doesn't require a Chrome process to be loaded up (which I believe is how CefGlue works, if I'm not mistaken). Avoiding the Chrome process was my primary reason for choosing Avalonia over Electron for my project.

Thanks! :)

PS - are there any implementation examples/demos or documentation for this that I can reference? thx again

PS Again - when I say "WebBrowser" equivalent I should clarify that it doesn't need to be used for anything complex. I'm essentially rendering Markdown to HTML using Markdig. So it will be some headers, bold, italic, links, etc. No crazy layout or anything.

custom font not work

I use the demo to set custom fonts， like this：

var f = new FontFamily(
            new Uri("avares://AvaloniaPreviewApp/Assets/Fonts/CustomFont.ttf"),
            "1 Smoothy DNA");

HtmlRender.AddFontFamily(f);

HtmlLabel and HtmlControl Unable to use custom font rendering, but the same code works fine in WPF

.css class "Display: flex;" dose not render when applyed

Css in the style div on the head does not respect the display flag flex, and renders nothing with the class applyed.

Comment - thank you!

[Discussion]
Overrall I think HtmlRenderer is pretty good and will be using it. Thank you for providing it!

margin:auto does not work

margin:auto does not appear to be supported.

Means, for example, you can't center an image as described here:

https://www.w3schools.com/csS/css_align.asp

Update used Avalonia version / update nuget package

Is it possible to update the used Avalonia version in this project? I was using the nuget package of this project (version 0.6.1), in conjunction with NetSparkle.
When trying to open an update window from the netsparkle library the following error is thrown:

When I download the source code of this project and remove the nuget package reference and change it to a project reference, everything is working fine.
For now I can workaround by using the source code of this repository, but a refreshed nuget package would come in handy.

Feature request - support tab-size

Does not support setting of tab-size.

This would be easy to add, yes?

(In the screenshot below, they all align vertically but they shouldn't.)

Does not support float

Just say'in.

font-weight appears to recognise only normal and bold

The CSS style font-weight:400; generates bold. It would be nice if this recognised numbers.

No scrolling in stack panel

When you place the render in a stack panel the scroll bar disappears.

Trivial - &ensp; and &emsp; not recognised

Per title.

Just want to say -- this is brilliant. Just what I needed. Thank you!

HtmlLabel.cs seems not to be correct ...

Hi, I am particularly referring to the following code within HtmlLabel.cs and there f.e. to the first else if. Something seems to be missing there. Since Avalonia at the moment seems not to be capable of displaying text with inlines in it, I hoped that I could somehow use your HtmlRenderer ;).

      /// <summary>
        /// Handle when dependency property value changes to update the underline HtmlContainer with the new value.
        /// </summary>
        private static Action<IAvaloniaObject, AvaloniaPropertyChangedEventArgs> OnAvaloniaProperty_valueChanged = new Action<IAvaloniaObject, AvaloniaPropertyChangedEventArgs>((AvaloniaObject, e) =>
        protected override void OnPropertyChanged<T>(AvaloniaPropertyChangedEventArgs<T> e)
        {
            var control = AvaloniaObject as HtmlLabel;
            if (control != null)
            base.OnPropertyChanged(e);
            if (e.Property == AutoSizeProperty)
            {
                if (e.Property == AutoSizeProperty)
                if (e.NewValue.GetValueOrDefault<bool>())
                {
                    if ((bool)e.NewValue)
                    {
                        AvaloniaObject.SetValue(AutoSizeHeightOnlyProperty, false);
                        control.InvalidateMeasure();
                        control.InvalidateVisual();
                    }
                    SetValue(AutoSizeHeightOnlyProperty, false);
                }
                else if (e.Property == AutoSizeHeightOnlyProperty)
            }
            else if (e.Property == AutoSizeHeightOnlyProperty)
            {
                if (e.NewValue.GetValueOrDefault<bool>())
                {
                    if ((bool)e.NewValue)
                    {
                        AvaloniaObject.SetValue(AutoSizeProperty, false);
                        control.InvalidateMeasure();
                        control.InvalidateVisual();
                    }
                    SetValue(AutoSizeProperty, false);
                }
            }
        });

        }
        #endregion
    }

Doesn't work on nightly

When trying to use it on the nightly, I get the following error:

System.IO.FileNotFoundException: Could not load file or assembly 'Avalonia.Visuals, Version=0.10.0.0, Culture=neutral, PublicKeyToken=c8d484a7012f9a8b'. The system cannot find the file specified.

I assume that is because of this change:
https://github.com/AvaloniaUI/Avalonia/wiki/Breaking-Changes

Avalonia.Animation, Avalonia.Input, Avalonia.Interactivity, Avalonia.Layout, Avalonia.Visuals and Avalonia.Styling assemblies were merged into a Avalonia.Base assembly. While API surface wasn't changed, it's still a binary breaking change, and third-party packages needs to be recompiled to work with a new version.

So this package needs to be recompiled to work with it.
