Render problem with "Grid.ColumnDefinitions" on runtime

[cemalgulbeyaz]

I have using SharpVector library in my project (WPF Core) to showing SVG images and this is the my reference " < PackageReference Include="SharpVectors.Reloaded" Version="1.8.1" / > "
The problem is happening if i use the svg image in grid with column definations. SVG image is render and showing while desing time with column defination but if i go to debug and runtime, it doesn't render and show. Everyting works normal without column defination. I put the xaml codes and screenshots below

With Grid.ColumnDefinitions

<Grid>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="50*" />
            <RowDefinition Height="350*" />
            <RowDefinition Height="100*" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="50*" />
            <ColumnDefinition Width="700*" />
            <ColumnDefinition Width="50*" />
        </Grid.ColumnDefinitions>
        <Button Style="{DynamicResource ResourceKey=TransparentButton}" 
                Grid.Column="0"
                Grid.Row="0"
                Grid.RowSpan="3"
                Background="Transparent" >
            <Image Source="{svgc:SvgImage /CustomControls/images/left-arrow.svg}" Margin="15" RenderTransformOrigin="0.5,0.5"/>
        </Button>
    </Grid>
</Grid>

Without Grid.ColumnDefinitions

<Grid>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="50*" />
            <RowDefinition Height="350*" />
            <RowDefinition Height="100*" />
        </Grid.RowDefinitions>
        <Button Style="{DynamicResource ResourceKey=TransparentButton}" 
                Grid.Column="0"
                Grid.Row="0"
                Grid.RowSpan="3"
                Background="Transparent" >
            <Image Source="{svgc:SvgImage /CustomControls/images/left-arrow.svg}" Margin="15" RenderTransformOrigin="0.5,0.5"/>
        </Button>
    </Grid>
</Grid>

@cemalgulbeyaz Normal WPF behavior of layout. You can either control the dimension with the Grid dimension definition or set the dimension of the Image. By design, SharpVectors does not control the size of the generated drawing, allowing you to have full control.

[cemalgulbeyaz]

@paulushub Thanks to you for information. Yes you are right if i set the Width and Height for Grid wich one cover the Image is works fine. But there is another situation now. I using this Grid in a UserControl and this user control size can change depending on manin view. I have tried to set Auto width and height ( already default value :) ) for Grid but it didn't work. I have to figure out this one now :)

[paulushub]

Image has stretch property that determines how it flows with the layout.

I using this Grid in a UserControl and this user control size can change depending on main view.

The question then is how do you want the Image control to behave? Depending on your requirements you can control the sizes of the various controls or dynamically change the size definition of the grid in the C# code-behind. With this flexibility of the WPF layout and vector nature of the drawing output from SharpVectors, we decided to simply hand-off and let the user take the control.

The only time we try to restrict the size of the SharpVectors drawings is when rendering static image (bitmap), so the SvgImage has PixelWidth/PixelHeight properties to handle that.
Even SvgImage has a base class SvgImageBase, which handles the conversions, and you can extend this to create your customized behavior or use other controls (see the documentations).

I downgraded to version 1.8.0 to get the previous behaviour.

[paulushub]

I downgraded to version 1.8.0 to get the previous behaviour.

What behavior changed for you?

[cemalgulbeyaz]

@paulushub Ok i figured it by sertting MinWidth for CloumnDefination. Thanks for helping

[GioviQ]

I downgraded to version 1.8.0 to get the previous behaviour.

What behavior changed for you?

With 1.8.1 I do not see anymore SvgViewbox

[paulushub]

With 1.8.1 I do not see anymore SvgViewbox

Sorry, I could not verify your issue. I have just tested the three Nuget packages

• SharpVectors with .NET 4.8
• SharpVectors.Reloaded with .NET 4.6.2
• SharpVectors.Wpf with .NET 4.0

All show the SvgViewbox without any problem:

SharpVectors.Wpf with .NET 4.7.2

with 1.8.0 visible, with 1.8.1 not

The following simple use in user-control works with the SharpVectors.Wpf, .NET 4.7.2

<UserControl x:Class="WpfApp11.UserControl1"

             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:WpfApp11"
             xmlns:svgc="http://sharpvectors.codeplex.com/svgc/"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">

    </Grid>
</UserControl>

I do not know what is falling in your codes. Can you name all the packages/versions in your code or post a sample project for testing?

@GioviQ Fix the source Uri. With 1.8.1 there are several improvements and fixes in the support for the Uri to make it work in both design mode and runtime.
For the sample given, simply change the Uri to Source="/check-mark.svg" and it will work in both design mode and runtime.

The Uri Source="/WpfApp1;Component/check-mark.svg" is for a resource file in referenced assembly, see Using Pack URIs in Markup.
The design mode still tries to make it work, since it scans several possible sources, but it fails in runtime, which does not need all the additional scanning to work if the Uri is valid.

Also, SharpVectors adds support for assembly name with the AppName property, and it this case it will be AppName="WpfApp1".

[GioviQ]

Still I do not understand the need to remove the support to a valid URI just present in https://learn.microsoft.com/en-us/dotnet/desktop/wpf/app-development/pack-uris-in-wpf?view=netframeworkdesktop-4.8

[paulushub]

Still I do not understand the need to remove the support to a valid URI just present in

File	Relative pack URI	Adding an example
Resource file in local assembly	"/ResourceFile.xaml"	"/check-mark.svg"
Resource file in referenced assembly	"/ReferencedAssembly;component/ResourceFile.xaml"	"/WpfApp1;Component/check-mark.svg"

Again, SharpVectors does not expect the Resource file in referenced assembly format. It worked in the 1.8.0 versions of the SvgCanvas and SvgViewbox because these were not updated to the Uri supports found in SvgImage.

The updated Uri support in 1.8.1 did not break any samples in the SharpVectors, because all used the Resource file in local assembly format. If you wish to specify the referenced assembly name, SharpVectors provides AppName property for that.

You can avoid all that by providing the Full pack URI instead of the Relative pack URI.

In design mode, several possible scans and checks are made (WPF does not provide design time interfaces for controls), which is too expensive for runtime - loading all resources and checking for the existence like File.Exists is too expensive.
