&nbsp; 
## Installation
```
Install-Package Vitvov.Maui.PDFView
```

&nbsp; 
## Usage
Add `.UseMauiPdfView()` to MauiProgram
```C#
using Maui.PDFView;

public static class MauiProgram
{
 public static MauiApp CreateMauiApp()
 {
 var builder = MauiApp.CreateBuilder();
 builder
 .UseMauiApp<App>()
 .UseMauiPdfView(); // <- Write this

return builder.Build();
    }
}
```

&nbsp; 
Add `PdfView` to XAML
```xaml
<ContentPage
 x:Class="Example.Business.UI.Pages.MainPage"
 xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
 xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
 xmlns:pdf="clr-namespace:Maui.PDFView;assembly=Maui.PDFView">

<pdf:PdfView
 IsHorizontal="{Binding IsHorizontal}"
 Uri="{Binding PdfSource}"
 MaxZoom="4"
 PageIndex="{Binding PageInex}"
 PageChangedCommand="{Binding PageChangedCommand}">
 </pdf:PdfView>

</ContentPage>
```

&nbsp; 
Set `PdfSource` in ViewModel
```C#
internal partial class MainPageViewModel : ObservableObject
{
 [ObservableProperty] private string? _pdfSource;

[RelayCommand] private void ChangeUri()
    {
        try 
        {
            //  See the example project to understand how to work with paths.
            PdfSource = "/path/to/file.pdf";

//  You can set the Uri property to null to clear the component.
            //PdfSource = null;
        }
        catch(Exception ex)
        {
             // handle exceptions
        }
    }
}
```

&nbsp; 
## Personalization
You can customize the way pages are displayed by modifying the `PageAppearance` property in the `PdfView` component.
```xaml
<pdf:PdfView Uri="{Binding PdfSource}">

<pdf:PdfView.PageAppearance>
 <pdf:PageAppearance 
 Margin="16,8" 
 ShadowEnabled="True"
 Crop="64,32"/>
 </pdf:PdfView.PageAppearance>

</pdf:PdfView>
```

&nbsp; 
## Helper classes implementing `IPdfSource`
The `PdfView` component works **only with file paths**. This is because the native platform components primarily operate with file paths, and handling different PDF data sources directly inside the component would significantly complicate the code.

Therefore, you must always provide a **file path** regardless of the form your PDF data takes—whether it’s a byte array, a stream, an asset, or a URL.

To simplify working with these data sources, the component includes helper classes that implement the `IPdfSource` interface:

- `AssetPdfSource`
- `ByteArrayPdfSource`
- `FilePdfSource`
- `HttpPdfSource`

Example of using PdfSource
```C#
[RelayCommand] private async Task UploadUri()
{      
    var source = new HttpPdfSource("https://www.adobe.com/support/products/enterprise/knowledgecenter/media/c4611_sample_explain.pdf");
    PdfSource = await source.GetFilePathAsync();
}

[RelayCommand] private async Task UploadAsset()
{
    var source = new AssetPdfSource("Example.Resources.PDF.pdf2.pdf");
    PdfSource = await source.GetFilePathAsync();
}
```

You can also create your own implementation of the `IPdfSource` interface to address your specific needs.
