Lyo.Pdf.Web.Components 3.0.0

Lyo.Pdf.Web.Components

Blazor / MudBlazor PDF UI: an HTML to PDF workbench, a PDF annotation workbench, and LyoPdfAnnotator so a user can draw bounding-box regions on a PDF and emit PdfBoundingBox payloads.

Targets net10.0. Razor SDK with FrameworkReference Microsoft.AspNetCore.App and MudBlazor 9.3+.

Examples

Add annotator services

services.AddPdfAnnotatorService(); // IPdfAnnotatorService -> BrowserPdfAnnotator
services.AddPdfAnnotatorInterop(); // LyoPdfAnnotatorController (scoped)

Components

• HtmlToPdfWorkbench.razor. Paste HTML or upload an .html / .htm / .txt file, pick PDF, PNG, JPEG, or WebP, and for PDF pick paper and orientation. The result previews in the page and can be downloaded.
• PdfAnnotationWorkbench.razor. Hosts LyoPdfAnnotator and shows a live table of saved annotations and their extracted payloads.
• PdfAnnotator/LyoPdfAnnotator.razor (+ LyoPdfAnnotator.razor.cs, LyoPdfAnnotatorResultsView.razor). Drawing canvas and result list. Fires AnnotationsChanged and AnnotationsSaved.

Annotator services

• IPdfAnnotatorService (BrowserPdfAnnotator). After the user finishes annotating a PDF given as Stream, byte[], or file path, returns IReadOnlyDictionary<string, PdfBoundingBox> (AnnotateAsync / AnnotateFileAsync).
• LyoPdfAnnotatorController. Scoped controller the Blazor components use.
• LyoPdfAnnotationResult. Payload for each saved region: Key, BoundingBoxSummary, ExtractionType (BoundingBoxText, KeyValue, Table), ExtractedText, optional KeyValuePairs / TableRows, KnownKeys, TableHeaders, YTolerance, KeyValueLayout (PdfKeyValueLayout), InferFormattingFlags (PdfInferFormattingFlags), KeyValueInferDelimiters, TableKeyColumnLabel, ColumnCount, and ColumnTexts.

DI registration

Pair with Lyo.Pdf's AddPdfService(...) so the annotator can call IPdfReader.Text for bounding-box extraction.

Browser scripts

Scripts sit under wwwroot/scripts/. Point at them from the host page or via the usual Razor class-library _content/Lyo.Pdf.Web.Components/ path.
