Lyo.Pdf.Models

Interfaces and value types for the Lyo PDF stack. Defines the contracts implemented by Lyo.Pdf so consumers can depend on IPdfService, IPdfReader, IPdfWriter, and ITextExtractor without pulling in PdfPig or PDFsharp directly.

Service contracts

  • IPdfService — façade for loading PDFs (OpenFromFile/Bytes/Stream plus …Async and batch variants), URL loading (OpenFromUrlAsync / OpenFromUrlsAsync — async only), creating empty / opening for edit (CreateEmpty, OpenForEdit / OpenForEditAsync), and merging (MergePdfs, MergePdfsToFile, MergePdfsToStream, MergePdfFiles, MergePdfBytes, all sync + async).
  • IPdfReader (IDisposable, IAsyncDisposable) — open PDF: SourceBytes (immutable buffer for merges / OpenForEdit), Metrics, Text (ITextExtractor), GetInfo(), and GetPageSizePoints(pageNumber1Based). Not thread-safe.
  • IPdfWriter (IDisposable) — PdfSharp-backed editor with PageCount, ImportPagesFrom(IPdfReader) / ImportPagesFrom(ReadOnlySpan<byte>), RemovePage, InsertBlankPage, ReorderPages, ToBytes, Save / SaveAsync, and CopyTo / CopyToAsync. Page indices are zero-based; not thread-safe.
  • ITextExtractor — composition of IPdfDocumentText + IPdfDocumentSections, reachable as IPdfReader.Text.
  • IPdfDocumentText — words / lines (GetWords, GetLines, GetWordsBetween, GetLinesBetween), bounding-box and columnar reads (GetLinesInBoundingBox, GetColumnarTextInBoundingBox, GetColumnarText), key/value extraction (ExtractKeyValuePairs with page, word-list, PdfSection, and section-name overloads, plus InferKeyValuePairsFromFormatting), table extraction (ExtractTable / ExtractDataTable with the same overload shapes plus ParseBytesAsDataTable), and inference helpers (InferTableHeadersFromFormatting). Every method has matching sync and async variants.
  • IPdfDocumentSections — section slicing: GetWordsBetweenSections, GetLinesBetweenSections / GetLinesBetweenSectionsAsync, GetSection / GetSectionAsync. Section navigation is anchored by ordered section labels with optional defaultEndSection, startPage, endPage, and yTolerance.

Value types

  • PdfInfo — PageCount, Title, Author, Subject, Creator, Producer, FilePath, Url, CreationDate, ModifiedDate.
  • PdfWord(Text, BoundingBox, Format?) and PdfWordFormat(FontSize?, FontName?, FontBold, FontItalic, FontColor?, FontUnderline).
  • PdfTextLine(Y, Words, Text) — words on the same visual row.
  • PdfBoundingBox(Page, Box) — 1-based page + Lyo.Common.Records.BoundingBox2D in PDF points.
  • PdfColumnarText(Columns) with ToCombinedString(separator).
  • PdfSection(Name, StartPage, EndPage, Lines) with computed Words property.
  • ColumnHeader(Label, IsKey = false) — drives table extraction; IsKey columns anchor a new row, others let unmatched lines append to the previous row.
  • KvColumnResult(ColumnIndex, Values) with KvColumnResult.Merge(...) helper.
  • PdfKeyValueLayout — Horizontal (value to the right of the key) or Vertical (value below the key).
  • PdfInferFormattingFlags — None, Bold, Semicolon (punctuation-terminated labels), Underline.

Options

  • PdfServiceOptions — knobs registered as a singleton by AddPdfService(...): DefaultYTolerance (5.0), DefaultKeyValueGap (0.0), TableHeaderMergeThreshold (20.0), TableHeaderMatchThreshold (0.75), TableColumnXTolerance (5.0), BoundingBoxOverlapThreshold (0.8), MaxContinuationYGap (10.0), MaxContinuationXDistance (100.0), ValueColumnXTolerance (20.0), KeyValueStackedMaxFirstGap (120.0), MaxPdfSizeBytes (falls back to SuggestedMaxPdfSizeBytes = 25 MiB), EnableMetrics (default false), and configuration SectionName = "PdfServiceOptions". MaxTotalLoadedBytes is [Obsolete]; the shared catalog is gone — each IPdfReader is caller-owned.
