The possibly best solution is to include fonts files as embedded resources and then loading them as streams 😁 Embedded resources are included in the final binary, so it makes sure that they are always available. |

@MarcinZiabek I tried Using QuestPDF in Blazor but I'm getting error. Steps:
<PackageReference Include="QuestPDF" Version="2022.12.1" />
<PackageReference Include="SkiaSharp.Views.Blazor" Version="2.88.3" />
@page "/"
@using QuestPDF.Drawing;
@using QuestPDF.Fluent;
@using QuestPDF.Helpers;
@inject HttpClient Http;
@if (Base64String is not null)
{
<iframe src="@($"data:application/pdf;base64,{Base64String}")"></iframe>
}
@code {
protected string? Base64String { get; set; }
private const string _font = "NotoSansSmall";
protected async override Task OnInitializedAsync()
//protected override void OnInitialized()
{
FontManager.RegisterFont(await Http.GetStreamAsync(@"http://localhost:5119/NotoSansSmall.ttf"));
//FontManager.RegisterFont(File.OpenRead(@"NotoSansSmall.ttf"));
var document = Document.Create(container =>
{
container.Page(page =>

page.ContinuousSize(3, QuestPDF.Infrastructure.Unit.Inch);
page.MarginVertical(5);
page.MarginHorizontal(10);

});
document.WithMetadata(new QuestPDF.Drawing.DocumentMetadata
{
Title = "Articles Summary",
Author = "Abdul Rahman",
Creator = "I Love .NET",
PdfA = true
});
//Base64String = document.GenerateImages().First().ToString();
using var memstream = new MemoryStream();
document.GeneratePdf(memstream);
Base64String = Convert.ToBase64String(memstream.ToArray());
}
}I get the following Error: Please assist me on this. I'm planning to write an article showing usage of QuestPDF in blazor wasm. But got stuck with this issue. |
