I placed two texts on the window, but the display effects are inconsistent. How can I make Glyphs achieve the same display effect as TextBlock?

Hi,@HoWe Yu. Welcome to Microsoft Q&A.

If you want the text rendered by Glyphs and TextBlock to be consistent, you could refer to the following solution.

You need to cancel the additional settings for TextBlock: you need to delete <Window>'s TextOptions.TextFormattingMode="Display".

<Window
		...
        WindowStartupLocation="CenterScreen"      
        Background="#FFFFFF"
        TextOptions.TextRenderingMode="Aliased"
        Title="MainWindow" Height="720" Width="1280">

    <Grid x:Name="MainGrid">
        <Grid x:Name="PaperBox" Margin="0"></Grid>

        <Glyphs x:Name="MyGlyphs"  FontUri="C:\WINDOWS\Fonts\simsun.ttc" FontRenderingEmSize="13"  UnicodeString="Hello World!" Fill="Black" OriginX="100" OriginY="80" />

        <TextBlock x:Name="MyTextBlock" Text="Hello World!" FontFamily="NSimSun" FontSize="13" FontWeight="Normal" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="100"></TextBlock>
    </Grid>
</Window>

Hi,@HoWe Yu.

In my testing, I found that simply adjusting TextOptions.TextFormattingMode="Ideal" could make Glyphs and TextBlock render consistently.

Let me rephrase this: How to turn off anti-aliasing on Glyphs

Hi,@HoWe Yu.

If you want to turn off anti-aliasing on Glyphs, you could try using the following code.

RenderOptions.SetEdgeMode(MyGlyphs,EdgeMode.Aliased);

However, text objects are always displayed with anti-aliasing, as described in the relevant documentation. Although you could explicitly specify the TextFormattingMode of Glyphs with the following code, you still cannot make Glyphs render the same font as the TextBlock.

TextOptions.SetTextFormattingMode(MyGlyphs,TextFormattingMode.Display);

Setting <Glyphs FontRenderingEmSize="14"> could render more similarly. If you want to enable TextOptions.TextFormattingMode="Display" and still need Glyphs to render the same, you may need a custom font.
